				-</li>
			
 
				-<li><div> Position the camera node in its start location.</div>
			
 
				-</li>
			
 
				-<li><div> Use activateCamera() to give the control of the camera to this node. You now see the scene from this camera&#039;s point of view. For example to see through the camera node named “top view”, 6 seconds after the start of the cinematic, you&#039;d write <pre>cinematic.activateCamera&#40;6, &quot;topView&quot;&#41;;</pre></div>

				-<div>

				-<p>
			
 
				-
			
 
				-A PhysicsHingeJoint is an invisible connection between two nodes – here between the pendulum body and the hook. Why are hinges and joints represented by the same class? Hinges and joints have something in common: They constrain the <em>mechanical degree of freedom</em> (DOF) of another object. 
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Consider a free falling, “unchained” object in physical 3D space: It has 6 DOFs:
			
 
				-</p>
			
 
				-<ul>
			
 
				-<li><div> It translates along 3 axes</div>
			
 
				-</li>
			
 
				-<li><div> It rotates around 3 axes</div>
			
 
				-</li>
			
 
				-</ul>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-Now consider some examples of objects with joints:
			
 
				-</p>
			
 
				-<ul>
			
 
				-<li><div> An individual chain link is free to spin and move around, but joined into a chain, the link&#039;s movement is restricted to stay with the surrounding links.</div>
			
 
				-</li>
			
 
				-<li><div> A person&#039;s arm can rotate around some axes, but not around others. The shoulder joint allows one and restricts the other.</div>
			
 
				-</li>
			
 
				-<li><div> A door hinge is one of the most restricted types of joint: It can only rotate around one axis. </div>
			
 
				-</li>
			
 
				-</ul>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-You&#039;ll understand that, when creating any type of joint, it is important to correctly specify the DOFs that the joint restricts, and the DOFs that the joint allows. For the typical DOF of a <a href="/com/jme3/gde/core/docs/jme3/advanced/ragdoll.html">ragDoll</a> character&#039;s limbs, jME even offers a special joint, <code>PhysicsConeJoint</code>.

				-<h2><a>Creating the Joint</a></h2>
			
 
				-<div>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-You create the PhysicsHingeJoint after you have created the nodes that are to be chained together. In the code snippet you see that the PhysicsHingeJoint constructor requires the two node objects. You also have to specify axes and pivots – they are the degrees of freedom that you just heard about.

				-<li><div> The localizer only sees the strings, without any context. E.g. does “Search History” mean “display the history of searches”, or “search through the history”? ⇒ Use clear key labels and work closely with the localizers if they require extra info.</div>

				-Some parameters are “optional” because they are somewhat advanced. If you don&#039;t know what an option means, chances are that you are not using this feature in your textures – and you don&#039;t need to specify it. (E.g. YCoCg and LATC are image compression formats; Minnaert and WardIso are shader types.)
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Also note that many other parameters are optional, even if they are not explicitly marked optional. For example, it&#039;s okay to specify solely the <code>DiffuseMap</code> and <code>NormalMap</code> when using <code>Lighting.j3md</code>. You are only using a subset of what is possible, but if that&#039;s what you want, you can do that. The developer should be in contact with the designer regarding what jME features individual Materials/Textures require.

If you don&#039;t know what an option means, chances are that you are not using this feature in your textures – and you don&#039;t need to specify it. (E.g. YCoCg and LATC are image compression formats; Minnaert and WardIso are shader types.)
			
 
				+Also note that many other parameters are optional, even if they are not explicitly marked optional. For example, it&#039;s okay to specify solely the <code>DiffuseMap</code> and <code>NormalMap</code> when using <code>Lighting.j3md</code>. You are only using a subset of what is possible, but if that&#039;s what you want, you can do that. The developer should be in contact with the designer regarding what jME features individual Materials/Textures require.</p></div><h3><a

If we would execute the operations directly in the simpleUpdate() loop, it would block the game  each time a NPC wants to move from A to B. Even if we move this behaviour into the update() method of a dedicated NPC Control, we would still get annoying freeze frames, because it still runs on the same update loop thread.

				-Most of the new SpiderMonkey <acronym title="Application Programming Interface">API</acronym> now exists as a set of interfaces and helper classes in the &#039;com.jme3.network&#039; package.  For most users, this package and the &#039;message&#039; package will be all they need to worry about.  The &#039;base&#039; and &#039;kernel&#039; packages only come into play when implementing custom network transports or alternate client/server protocols (<em>which are now possible</em>).

				-Clients and Servers can be created from the factory methods on the Network helper class.  Once a Server instance is created and started, it can accept remote connections from Clients.  The Client objects represent the client-side of a client→server connection.  Within the Server, these are HostedConnections.  This is a distinct change from the old <acronym title="Application Programming Interface">API</acronym>.

				-As you&#039;ve seen above, there are quite a few changes necessary to migrate to the new <acronym title="Application Programming Interface">API</acronym>.  You might be asking yourself if it&#039;s worth the trouble.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-The bottom line is that the old architecture had threading and stability issues that just couldn&#039;t be fixed in any reasonable way.  Some were minor, others kind of severe… and they combined to make trouble.  If you&#039;ve ever wondered why sometimes your clients connect and then the network connection hangs or stops sending data.  Or if you&#039;ve ever wondered why UDP/unreliable messages get corrupted or somehow won&#039;t deserialize properly then you&#039;ve run into some of these issues.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Moreover, the lack of thread safety meant that user code sometimes had to do some strange and/or complicated work-arounds.  The goal should be that the <acronym title="Application Programming Interface">API</acronym> should just work like it looks like it will with a minimum of hassle.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-The new architecture is built from the ground up for threading stability and for a clean separation between the public <acronym title="Application Programming Interface">API</acronym>, the message passing layer, and the underlying network transport implementations.  You should be able to throw all kinds of stuff at it that would make the old system fall over and it should just hum along.  
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-There will certainly be some growing pains as we work the kinks out of the new system but it is already much more stable in even the most basic of stress tests.

This removes some of the inconsistency on when to use the old player ID and when to use the old client ID as the new client ID serves both purposes.  This leaves the game to be able to define its own player ID based on whatever user criteria it wants.</p><p><p><div
			
 
				+class="noteclassic">Many of the reasons for accessing the client ID on the server can now be taken care of using the session attributes on HostedConnection.  It seems like a common use-case for these IDs was to look-up player/client-specific information in a java.util.Map.  This information can now be set directly on the HostedConnection.</div></p></p></div><h3><a

				+title="Application Programming Interface">API</acronym>.  You might be asking yourself if it&#039;s worth the trouble.</p><p> The bottom line is that the old architecture had threading and stability issues that just couldn&#039;t be fixed in any reasonable way.  Some were minor, others kind of severe… and they combined to make trouble.  If you&#039;ve ever wondered why sometimes your clients connect and then the network connection hangs or stops sending data.  Or if you&#039;ve ever wondered why UDP/unreliable messages get corrupted or somehow won&#039;t deserialize properly then you&#039;ve run into some of these issues.</p><p> Moreover, the lack of thread safety meant that user code sometimes had to do some strange and/or complicated work-arounds.  The goal should be that the <acronym
			
 
				+title="Application Programming Interface">API</acronym> should just work like it looks like it will with a minimum of hassle.</p><p> The new architecture is built from the ground up for threading stability and for a clean separation between the public <acronym
			
 
				+title="Application Programming Interface">API</acronym>, the message passing layer, and the underlying network transport implementations.  You should be able to throw all kinds of stuff at it that would make the old system fall over and it should just hum along.</p><p> There will certainly be some growing pains as we work the kinks out of the new system but it is already much more stable in even the most basic of stress tests.</p><div

				-<p>
			
 
				-
			
 
				-You can control the game by triggering forces; or may want to respond to collisions, e.g. by substracting health points, or by playing a sound. To specify how the game responds to physics events, you use <a href="/com/jme3/gde/core/docs/jme3/advanced/physics_listeners.html">Physics Listeners</a>. 
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Do not overuse physics nodes. Although the physics nodes are put to “sleep” when they are not moved, creating a world solely out of dynamic physics nodes will quickly bring you to the limits of your computer&#039;s capabilities.

				+Do not overuse physics nodes. Although the physics nodes are put to “sleep” when they are not moved, creating a world solely out of dynamic physics nodes will quickly bring you to the limits of your computer&#039;s capabilities.
			
 
				 You can use normal non-physical Nodes in the same scene next to physical ones. Use the non-physical ones for non-solid things for which you do not want to detect collisions (ghost, foliage, plants, effects, …). This improves performance.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				 If you get weird behaviour, such as physical nodes jittering wildy and being ejected for no apparent reason, it usually means you have created an impossible state. Verify that none of the collision shapes overlap. This can happen when you create physical nodes in positions that are too close to other nodes; or if you position a physical node using setLocalTranslation() and it touches another node&#039;s collision shape.

				-The GameDev.net article describes how those effects are achieved, but the main idea is to generate waves from a height map, create ripples from a normal map, blend in the foam texture when the water depth is below a certain height, compute the refraction color with a clever color extinction algorithm, and then, display the reflection and specular effect by computing a Fresnel term (like in standard water effect). In addition this effect, allow to blend the water shore with the ground to avoid the hard edges effect of classic water effects based on grids or quads.

				 You can do this with the LodCalculator interface.
			
 
				 GeoMipMapping in TerraMonkey has been split into several parts: the terrain quad tree, and the LODGeomap. The geomap deals with the actual LOD and seaming algorithm. So if you want a different data structure for your terrain system, you can re-use this piece of code.
			
 
				 The quad tree (TerrainQuad and TerrainPatch) provide a means to organize the LODGeomaps, notify them of their neighbour&#039;s LOD change, and to update the geometry when the LOD does change.
			
 
				-To change the LOD it does this by changing the index buffer of the triangle strip, so the whole geometry doesn&#039;t have to be re-loaded onto the video card.

				-For physical vehicles, jME&#039;s uses the jBullet ray-cast vehicle. In this vehicle implementation, the physical chassis &#039;floats&#039; along on four non-physical vertical rays. 
			
 
				-</p>

				-Internally, each wheel casts a ray down, and using the ray&#039;s intersection point, jBullet calculates the suspension length, and the suspension force. The suspension force is applied to the chassis, keeping it from hitting the ground. The friction force is calculated for each wheel where the ray intersects with the ground. Friction is applied as a sideways and forwards force. <sup><a href="#fn__1">1)</a></sup>

				-You have learned how to create a Material, specify its properties, and use it on a Geometry. You know how to load an image file (.png, .jpg) as texture into a material. You know to save texture files in a subfolder of your project&#039;s <code>assets/Textures/</code> directory.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-You have also learned that a material can be stored in a .j3m file. The file references a built-in Material Definition and specifies values for properties of that MaterialDefinition. You know to save your custom .j3m files in your project&#039;s <code>assets/Materials/</code> directory.

Using the same value for each dimension scales an object proportionally, using different values stretches it. <br/>

				- Important: <strong>You do not specify the rotation in degrees from 0° to 360°, but in radians from 0.0f to 6.28f (FastMath.PI*2) !</strong> <br/>

				-Every milestone is made up of a development phase and a test phase. Here are some best practices:

				-<div>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-You have a list of features that you want in game, but which one do you implement first? You will keep adding features to a project that grows more and more complex, how can you minimize the amount of rewriting required? 
			
 
				-
			
 
				-</p>
			
 
				-<ol>
			
 
				-<li><div> Start with implementing the most complex game feature first – the one that imposes most constraints on the structure of your project (for instance, networking.)</div>
			
 
				-</li>
			
 
				-<li><div> Make sure the game&#039;s high-level frame (screen switching, networking, physics, loading/saving) is sound and solid before you implement low-level details of gameplay. </div>
			
 
				-</li>
			
 
				-<li><div> Only add one larger feature at a time. If there are complex interactions (such as “networking + physics”), start with a small test case (“one cube”) and work your way up, don&#039;t start with a whole scene.</div>
			
 
				-</li>
			
 
				-<li><div> Test for side-effects on existing code before you add the next feature.</div>
			
 
				-</li>
			
 
				-</ol>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-Acknowledge whether you want a feature because it is necessary for gameplay, or simply because “everyone else has it”. Successful high-performance games are the ones where someone made smart decisions what to keep and what to drop. 
			
 
				-</p>
			
 
				-<ul>
			
 
				-<li><div> Example: Everybody wants “full physics, AI, post-rendering effects, and multi-player networking”… Make certain you truly understand what that requires (e.g. client-server synchonization)! Your goal should be to bring out the essence of your game idea, don&#039;t water down gameplay but attempting to make it “do everything, but better”. </div>

				-<h3><a>Extend SimpleApplication</a></h3>
			
 
				-<div>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-Typically, developers extend a custom class off of jME3&#039;s com.jme3.app.SimpleApplication (or even com.jme3.app.Application). For a racing game you would create a different base game class than for a space game or a shooter.
			
 
				-
			
 
				-</p>
			
 
				-<ol>
			
 
				-<li><div> Create a generic game class for your custom game:</div>
			
 
				-<ol>
			
 
				-<li><div> Create a jME3-based project with all necessary JARs on the classpath. </div>
			
 
				-</li>
			
 
				-<li><div> Create a class in this package that extends SimpleApplication, name it something like <code>my.company.MyBaseGame.java</code>.</div>
			
 
				-</li>
			
 
				-<li><div> Implement all generic features that the game type needs in the MyBaseGame class. For example methods for loading and saving scenes, physics, networking and multi-player logon screen, switching to settings screen, etc. </div>
			
 
				-</li>
			
 
				-<li><div> Include generic assets (company logo, reusable <acronym title="Graphical User Interface">GUI</acronym> elements in your company style, etc) in the MyBaseGame&#039;s assets directory.</div>
			
 
				-</li>
			
 
				-</ol>
			
 
				-</li>
			
 
				-<li><div> Create your actual game, e.g. a shooter: </div>
			
 
				-<ol>
			
 
				-<li><div> Create another jME3-based project, and a new package for the game itself, e.g. <code>my.company.zombieshooter.MyGame.java</code>. </div>
			
 
				-</li>
			
 
				-<li><div> Add MyBaseGame.jar to the classpath of MyGame.java.</div>
			
 
				-</li>
			
 
				-<li><div> Make MyGame.java&#039;s main class extend MyBaseGame. </div>
			
 
				-</li>
			
 
				-<li><div> The specific assets (scenes, models) of this game go into MyGame&#039;s own assets folder.</div>
			
 
				-</li>
			
 
				-<li><div> Now implement this game&#039;s mechanics and levels – without having to worry about logon&amp;settings screens and all the other features that you already dealt with in MyBaseGame.</div>
			
 
				-</li>
			
 
				-</ol>
			
 
				-</li>
			
 
				-</ol>

				-<h3><a>Controls and AppStates -- The Smart Way to Implement Game Logic</a></h3>
			
 
				-<div>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-As your jME3-based application grows more advanced, you may find yourself putting more and more tests in the simpleUpdate() loop, and passing around lots of object references. Don&#039;t implement game behaviour by copying and pasting boilerplate code! It is a best practice to move game behaviour into classes of their own. In jME3 these classes are Controls and AppStates.
			
 
				-
			
 
				-</p>
			
 
				-<ul>
			
 
				-<li><div> Use Controls to implement the behaviour of types of game entities. A character control that defines how this type of Spatials moves, an animation control that plays animations in this type of Spatial&#039;s model, etc.</div>
			
 
				-</li>
			
 
				-<li><div> Use AppStates to implement global game behaviour: A physics manager, a custom artificial intelligence manager, etc.</div>
			
 
				-</li>
			
 
				-<li><div> Use the simpleUpdate() loop for the remaining “one-off” tests and interactions.</div>
			
 
				-</li>
			
 
				-</ul>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-Both classes automatically hook into the main update loop. Instead of remote controlling game entities via simpleUpdate(), you define the desired behaviour in the update methods of custom Controls and AppStates. You then add Controls to Spatials, and AppStates to the application, and jME3 will automatically trigger the update methods. This cleans up your simpleUpdate() loop code considerably.

				-
			
 
				-Put your assets into subfolders of your project&#039;s <code>assets</code> directory. This is the default path where the assetManager looks for files.

				+class="level3"><p> As your jME3-based application grows more advanced, you may find yourself putting more and more tests in the simpleUpdate() loop, and passing around lots of object references. Don&#039;t implement game behaviour by copying and pasting boilerplate code! It is a best practice to move game behaviour into classes of their own. In jME3 these classes are Controls and AppStates.</p><ul><li
			
 
				+class="level1"><div
			
 
				+class="li"> Use Controls to implement the behaviour of types of game entities. A character control that defines how this type of Spatials moves, an animation control that plays animations in this type of Spatial&#039;s model, etc.</div></li><li
			
 
				+class="level1"><div
			
 
				+class="li"> Use AppStates to implement global game behaviour: A physics manager, a custom artificial intelligence manager, etc.</div></li><li
			
 
				+class="level1"><div
			
 
				+class="li"> Use the simpleUpdate() loop for the remaining &quot;one-off&quot; tests and interactions.</div></li></ul><p> Both classes automatically hook into the main update loop. Instead of remote controlling game entities via simpleUpdate(), you define the desired behaviour in the update methods of custom Controls and AppStates. You then add Controls to Spatials, and AppStates to the application, and jME3 will automatically trigger the update methods. This cleans up your simpleUpdate() loop code considerably.</p><p> Learn more about <a

				-Unit Tests (Java Assertions) have a different status in 3D graphics development than in other types of software. You cannot write any assertions that automatically test whether the rendered image looks correct, or whether interactions are intuitive. Still you should create simple test cases for separate game features such as loaders, content generators, effects. Run them now and then to see whether they still work as intended – or whether they are affected by side effects. Keep the test classes in a test directory in the project, but don&#039;t include them in the distribution.

				-Quality Assurance (QA) means maintaining a clear list of steps that must always work, and checking them. There can be bugs in software, but tasks such as installing and de-installing, saving and loading, starting/pausing/quitting the game, <em>must work</em>, no excuse. After every milestone, you go through the list again, on every supported operating system, and systematically look for regressions or bugs.

				-<p>
			
 
				-Alpha and Beta Testing means that you ask someone to try to install and run your game. It should be a real user situation, where they are left to figure it out by themselves (you only can include the usual read-me and help docs). Provide the testers with an easy method to report back descriptions of their problems, e.g. why they gave up. Evaluate whether these problems are exceptions or must be fixed for the game to be playable.

You cannot write any assertions that automatically test whether the rendered image looks correct, or whether interactions are intuitive. Still you should create simple test cases for separate game features such as loaders, content generators, effects. Run them now and then to see whether they still work as intended – or whether they are affected by side effects. Keep the test classes in a test directory in the project, but don&#039;t include them in the distribution.</p><p> Quality Assurance (QA) means maintaining a clear list of steps that must always work, and checking them. There can be bugs in software, but tasks such as installing and de-installing, saving and loading, starting/pausing/quitting the game, <em>must work</em>, no excuse. After every milestone, you go through the list again, on every supported operating system, and systematically look for regressions or bugs.</p><p> Alpha and Beta Testing means that you ask someone to try to install and run your game. It should be a real user situation, where they are left to figure it out by themselves (you only can include the usual read-me and help docs). Provide the testers with an easy method to report back descriptions of their problems, e.g. why they gave up. Evaluate whether these problems are exceptions or must be fixed for the game to be playable.</p></div><h3><a

				-<p>
			
 
				-In 3D space, speaking of an orthogonal only makes sense with respect to a plane. You need two vectors to uniquely define a plane. The cross product of the two vectors, <code>v1 × v2</code>, is a new vector that is perpendicular to this plane. A vector perpendicular to a plane is a called <em>Surface Normal</em>.

				-Most visible objects in a 3D scene are made up of polygon meshes – characters, terrains, buildings, etc. A mesh is a grid-like structure that represents a complex shape. The advantage of a mesh is that it is mathematically simple enough to render in real time, and detailed enough to be recognizable. 
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Every shape is reduced to a number of connected polygons, usually triangles; even round surfaces such as spheres are reduced to a grid of triangles. The polygons&#039; corner points are called vertices. Every vertex is positioned at a coordinate, all vertices together describe the outline of the shape.

				-You create 3D meshes in tools called mesh editors, e.g in Blender.

				-Textures are part of Materials. In the simplest case, an object could have just one texture, the Color Map, loaded from one image file. When you think back of old computer games you&#039;ll remember this looks quite plain.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-The more information you (the game designer) provide additionally to the Color Map, the higher the degree of detail and realism. Whether you want photo-realistic rendering or “toon” rendering (Cel Shading), everything depends on the quality of your materials and texture maps. Modern 3D graphics use several layers of information to describe one material, each layer is a Texture Map.

				-</p>
			
 
				-
			
 
				-<p>
			
 
				-A seamless texture is an image file that has been designed so that it can be used as tiles: The right edge matches the left edge, and the top edge matches the bottom edge. The onlooker cannot easily tell where one starts and the next one ends, thus creating an illusion of a huge texture. The downside is that the tiling becomes painfully obvious when the area is viewed from a distance. Also you cannot use it on more complex models such as characters.

				-Creating a texture for a cube is easy – but what about a character with a face and extremities? For more complex objects, you design the texture in the same ways as a sewing pattern: One image file contains the outline of the front, back, and side of the object, next to one another. Specific areas of the flat texture (UV coordinates) map onto certain areas of your 3D model (XYZ coordinates), hence the name UV map.

The renderer uses this as base to texture the reflective surface.

				-Of course these reflections are static and not “real”, e.g. the player will not see his avatar&#039;s face reflected, etc… But they cause the desired “glass/mirror/water” effect, and are fast enough to render in real usecases, it&#039;s better than nothing.

Depending on how close (or far) the camera is, the engine automatically renders a more (or less) detailed texture for the object. Thus objects look smooth from close up, but don&#039;t waste resources with unspottable details when far away. Good for everything, but requires more time to create and more space to store textures.

				-A procedural texture is generated from repeating one small image, plus some pseudo-random, gradient variations (Perlin noise). Procedural textures look more natural than static rectangular textures, for instance, they look less distorted on spheres. On big meshes, their repetitiveness is much less noticable than tiled seamless textures. Procedural textures are ideal for irregular large-area textures like grass, soil, rock, rust, and walls.

				-In 3D games, Skeletal Animation is used for animated characters, but in principle the skeleton approach can be extended to any 3D mesh (for example, an opening crate&#039;s hinge can be considered a joint). 
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Unless you animate a 3D cartoon, realism of animated characters is generally a problem: Movement can look alien-like mechanical or broken, the character appears hollow, or as if floating. Professional game designers invest a lot of effort to make characters animate in a natural way (including motion capturing).

				-An animated character has an armature: An internal skeleton (Bones) and an external surface (Skin). The Skin is the visible outside of the character and it includes clothing. The Bones are not visible and are used to interpolate (calculate) the morphing steps of the skin.

				-Non-player (computer-controlled) characters (NPCs) are only fun in a game if they do not stupidly bump into walls, or blindly run into the line of fire. You want to make NPCs “aware” of their surroundings and let them make decisions based on the game state – otherwise the player can just ignore them. The most common use case is that you want to make enemies interact in a way so they offer a more interesting challenge for the player. 
			
 
				-</p>

				-<p>
			
 
				-“Smart” game elements are called artificially intelligent agents (AI agents). An AI agent can be an NPC, but also an “automatic alarm system” that locks doors after an intruder alert, or a trained pet.

				-The domain of artificial intelligence deals, among other things, with:
			
 
				-</p>
			
 
				-<ul>
			
 
				-<li><div> Knowledge – An agent only “knows” what it can “see and hear”, this implies that things can be hidden from it. You can make a group of agents share knowledge (e.g. guards with two-way radios know, other guards don&#039;t know about the intruder).</div>
			
 
				-</li>
			
 
				-<li><div> Goal Planning – The agent has a priority to achieve a specific goal (a future state). It splits the goal into subgoals, determines tactics and strategies, and prioritizes them. The agent keeps testing whether the current state is closer to the (sub)goal. If unsuccessful, the agent changes the tactics/strategy. E.g. Finding the best path to reach a target in a changing environment.</div>
			
 
				-</li>
			
 
				-<li><div> Problem solving – The agent uses a given set of facts and rules to deduct what state it is in. In every state, only a certain subset of reactions makes sense. The actual decision depends on the agent&#039;s goal. Examples: If target in range, attack or protect base or raise alarm. If idle, lay traps or heal oneself or recharge ammunition. If floor on fire, then danger. If danger, escape or kamikaze.</div>

The advantage of a mesh is that it is mathematically simple enough to render in real time, and detailed enough to be recognizable.
			
 
				+Every shape is reduced to a number of connected polygons, usually triangles; even round surfaces such as spheres are reduced to a grid of triangles. The polygons&#039; corner points are called vertices. Every vertex is positioned at a coordinate, all vertices together describe the outline of the shape.

When texturing a wide area (e.g. walls, floors), you don&#039;t create one huge texture, instead you tile a small texture repeatedly to fill the area.
			
 
				+A seamless texture is an image file that has been designed so that it can be used as tiles: The right edge matches the left edge, and the top edge matches the bottom edge. The onlooker cannot easily tell where one starts and the next one ends, thus creating an illusion of a huge texture. The downside is that the tiling becomes painfully obvious when the area is viewed from a distance. Also you cannot use it on more complex models such as characters.</p></div><h2><a

For more complex objects, you design the texture in the same ways as a sewing pattern: One image file contains the outline of the front, back, and side of the object, next to one another. Specific areas of the flat texture (UV coordinates) map onto certain areas of your 3D model (XYZ coordinates), hence the name UV map.

You create a Cube Map to represent your environment, similar to a skybox. (Sphere Maps are possible, but often look too distorted.) You give the Cube Map a set of images showing a &quot;360° view&quot; of the completed scene. The renderer uses this as base to texture the reflective surface.
			
 
				+Of course these reflections are static and not &quot;real&quot;, e.g. the player will not see his avatar&#039;s face reflected, etc… But they cause the desired &quot;glass/mirror/water&quot; effect, and are fast enough to render in real usecases, it&#039;s better than nothing.</p></div><h2><a

Depending on how close (or far) the camera is, the engine automatically renders a more (or less) detailed texture for the object.

Good for everything, but requires more time to create and more space to store textures.</p></div><h2><a

Procedural textures look more natural than static rectangular textures, for instance, they look less distorted on spheres. On big meshes, their repetitiveness is much less noticable than tiled seamless textures. Procedural textures are ideal for irregular large-area textures like grass, soil, rock, rust, and walls.

You want to make NPCs &quot;aware&quot; of their surroundings and let them make decisions based on the game state – otherwise the player can just ignore them. The most common use case is that you want to make enemies interact in a way so they offer a more interesting challenge for the player.
			
 
				+&quot;Smart&quot; game elements are called artificially intelligent agents (AI agents). An AI agent can be an NPC, but also an &quot;automatic alarm system&quot; that locks doors after an intruder alert, or a trained pet.
			
 
				+The domain of artificial intelligence deals, among other things, with:</p><ul><li
			
 
				+class="level1"><div
			
 
				+class="li"> Knowledge – An agent only &quot;knows&quot; what it can &quot;see and hear&quot;, this implies that things can be hidden from it. You can make a group of agents share knowledge (e.g. guards with two-way radios know, other guards don&#039;t know about the intruder).</div></li><li
			
 
				+class="level1"><div
			
 
				+class="li"> Goal Planning – The agent has a priority to achieve a specific goal (a future state). It splits the goal into subgoals, determines tactics and strategies, and prioritizes them. The agent keeps testing whether the current state is closer to the (sub)goal. If unsuccessful, the agent changes the tactics/strategy. E.g. Finding the best path to reach a target in a changing environment.</div></li><li
			
 
				+class="level1"><div
			
 
				+class="li"> Problem solving – The agent uses a given set of facts and rules to deduct what state it is in. In every state, only a certain subset of reactions makes sense. The actual decision depends on the agent&#039;s goal. Examples: If target in range, attack or protect base or raise alarm. If idle, lay traps or heal oneself or recharge ammunition. If floor on fire, then danger. If danger, escape or kamikaze.</div></li></ul><p> There are lots of resources explaining interesting AI algorithms:</p><ul><li

				-Web Start allows your users to start your application by simply clicking a link that you provide, for example in a button on your web page. The browser downloads the JAR file and then automatically runs your game in an extra window. The only requirement is that the user&#039;s browser has the Java plugin installed. This is a very user-friendly way for your customers to play your game without any extra steps to install it. Optionally, you can set it up so the file is saved to their desktop and can be restarted later, so they do not need to be online to play.

				-AssetPacks are a way to package jME3 compatible assets like models, textures, sounds and whole scenes into a package that contains publisher info, license info, descriptions etc. for all of the assets. An AssetPack basically consists of an <code>assetpack.xml</code> file that describes the content and an <code>assets</code> folder that contains the content. The integrated browser in jMP allows you to add the assets of installed AssetPacks to any project you are doing.

				-The AssetPack browser in jMP makes browsing the installed AssetPacks easy. Browse categories, search for tags and find the right asset for your project. When you have found it, you can add it with one click to your current scene. The AssetPack manager will automagically copy all needed textures, sounds etc. to your projects assets folder.

				-The AssetPack browser uses a predefined directory to store the AssetPacks which is also used for new AssetPack projects. You can see and change the folder path in the AssetPack preferences (jMonkeyPlatform→Settings).

				-The global asset type can be “model”, “scene”, “texture”, “sound”, “shader” or “other”
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-With the “model” or “scene” types, the AssetPack browser will try to load and add a model file from the selected assets when the user selects “Add to SceneComposer”. Specify the “load this model with material” flag for the model file that should be loaded via the AssetManager, you can also specify multiple mesh or scene files to be loaded. All texture and other needed files will be copied to the users project folder.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-On the “Add Files” page you define the path of the files in the AssetPack. The importer tries to generate a proper path from the info entered on the first page. Note that for j3o binary models, the texture paths have to be exactly like they were during conversion. The given paths will also be used when copying the data to the users “assets” folder.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-With the “add files” button you can open a file browser to select files from your harddisk that will be copied into the <code>assets/</code> folder of the AssetPack project. With the “add existing” button you can add a file thats already in your AssetPack assets folder to a new asset item. This way you can reuse e.g. textures for asset items or make items for an existing collection of asset files that you copied to the projects assets folder.

				-You can specify a specific material to be used for the single mesh/scene files, just select it in the dropdown below the mesh or scene file. If you don&#039;t select a material file here, the first found material file is used or none if none is found.
			
 
				-</p>

				-If the material file is an Ogre material file (.material) it will be used for loading an Ogre scene or mesh file. If it is a jMonkeyEngine3 material file (.j3m), it will be applied to the mesh regardless of model type. Note that for j3o models you don&#039;t need material files as the material is stored inside the j3o file.

				-The jMonkeyPlatform supports the JUnit testing framework. It is a good practice to write tests (assertions) for each of your classes. Each test makes certain this “unit” (e.g. method) meets its design and behaves as intended. Run your tests after each major change and you immediately see if you broke something.

This documentation shows you how to make the most of the jMonkeyPlatform&#039;s assistive features.</p><p> <br/></p><p> Note: Since the jMonkeyPlatform is based on the NetBeans Platform framework, you can learn about certain jMonkeyPlatform features by reading the corresponding NetBeans IDE tutorials (in the &quot;see also links&quot;).</p></div><h2><a
			
 
				+name="testing">Testing</a></h2><div
			
 
				+class="level2"><p> The jMonkeyPlatform supports the JUnit testing framework. It is a good practice to write tests (assertions) for each of your classes. Each test makes certain this &quot;unit&quot; (e.g. method) meets its design and behaves as intended. Run your tests after each major change and you immediately see if you broke something.</p></div><h4><a

				-The original OgreXML <code>.mesh.xml</code>, <code>.scene</code>, <code>.material</code> and <code>.skeleton.xml</code> model files <strong>will not be included</strong> in the distribution <code>assets.jar</code> file of your distributed game, they are only available in the assets folder so you are able to recreate the <code>.j3o</code> file from the original if you ever come to change it in blender and have to export it again.

				-<h2><a>About the SceneViewer and SceneExplorer window</a></h2>
			
 
				-<div>
			
 
				-
			
 
				-<p>
			
 
				-
			
 
				-The SceneViewer and SceneExplorer windows are shared among plugins to save system resources. This means that you will have to keep an eye on what plugin is using the scene right now and what you are actually modifying in these windows.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-Most plugins will deliver their own UI elements to modify the scene so the SceneExplorer is more of a global tool. The simple SceneComposer however heavily relies on its functions as other plugins might too in the future.
			
 
				-</p>

				-<h3><a>About the projects AssetManager</a></h3>
			
 
				-<div>
			
 
				-
			
 
				-<p>
			
 
				-Each jMP project has its own internal AssetManager that has the projects assets folder registered as a FileLocator. When the project is run, the assets folder is compressed into a jar file and added to the projects main jar classpath. This way the editors in jMP and the running game have the same asset folder structure.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-You might wonder why jMP requires you to copy the model that is to be converted to j3o into the assets folder before. The Model Import Tool also copies the model and associated files to the project directory before converting. To load the model it needs to be in a folder (or jar etc..) that belongs to the projects AssetManager root. To load a model from some other folder of the filesystem, that folder would have to be added to the AssetManager root. If every folder that contains a model was in the root of the AssetManager, all textures named “hull.jpg” for example would be the same for the AssetManager and it would only deliver the texture of the first model folder that was added.
			
 
				-</p>
			
 
				-
			
 
				-<p>
			
 
				-To have a valid jME3 object, the paths to textures and other assets belonging to the model have to be read with the correct, final path that can then be stored in the j3o object. The j3o object will use those paths when it is loaded with the AssetManager and it requires the AssetManager to deliver the assets on those paths, this is why the folder structure while converting has to be the same as when loading.

This means that you will have to keep an eye on what plugin is using the scene right now and what you are actually modifying in these windows.</p><p> Most plugins will deliver their own UI elements to modify the scene so the SceneExplorer is more of a global tool.

				+class="level3"><p> Each jMP project has its own internal AssetManager that has the projects assets folder registered as a FileLocator. When the project is run, the assets folder is compressed into a jar file and added to the projects main jar classpath. This way the editors in jMP and the running game have the same asset folder structure.</p><p> You might wonder why jMP requires you to copy the model that is to be converted to j3o into the assets folder before. The Model Import Tool also copies the model and associated files to the project directory before converting. To load the model it needs to be in a folder (or jar etc..) that belongs to the projects AssetManager root. To load a model from some other folder of the filesystem, that folder would have to be added to the AssetManager root. If every folder that contains a model was in the root of the AssetManager, all textures named &quot;hull.jpg&quot; for example would be the same for the AssetManager and it would only deliver the texture of the first model folder that was added.</p><p> To have a valid jME3 object, the paths to textures and other assets belonging to the model have to be read with the correct, final path that can then be stored in the j3o object. The j3o object will use those paths when it is loaded with the AssetManager and it requires the AssetManager to deliver the assets on those paths, this is why the folder structure while converting has to be the same as when loading.</p></div>

				-Also note that although it its possible to directly link external model files (OgreXML, OBJ etc.), this is not recommended. Convert the original file to a j3o file by right-clicking it and selecting “Convert to jME Binary” before linking it. This is required because the original model files are not included in the release version of the application.

Tri-planar mapping does not use the texture coordinates of the geometry, but real world coordinates.

The advantages are that you can keep track of changes (who did it, when, and why), you can compare versions line-by-line, you can revert changes to files and lines, merge multiple changes to one file, and you can even undelete files.</p></div><h2><a

				-Really simple, but ZIP requires some explanation. The ZIPCompressedMessage class also has two extra methods; setLevel(int) and getLevel(). These methods are for setting the compression level, where 1 is best compression but slowest, and where 9 is weakest compression but fastest. Please note that 9 is <strong>not</strong> the so called &#039;store&#039; ZIP method, which simply stores file in the ZIP, instead of compressing it. This &#039;store&#039; feature is not in SpiderMonkey since otherwise it would not have been called compression.

				-Now of course I&#039;d love to see more compression methods in SpiderMonkey, so I&#039;ll discuss how to write your own. Let&#039;s just take GZIPCompressedMessage as example, since that one is the most straightforward. What I&#039;ve done, is I&#039;ve just created a GZIPCompressedMessage which extends CompressedMessage. It does not contain any extra messages, so the GZIPCompressedMessage class is practically &#039;empty&#039;. The magic happens at the serializer, which is called the GZIPSerializer (you can read about writing your own serializer <a href="/com/jme3/gde/core/docs/spidermonkey/tutorial/serializing.html">here</a>). Then I just registered the GZIPSerializer to GZIPCompressedMessage and presto - you&#039;re done. Don&#039;t forget that in the Serializer you need to use writeClassAndObject first and then compress that data, and for read you&#039;d need to use readClassAndObject after you&#039;ve uncompressed (inflated) the message. For this to be clear, it may be useful to read <object classid="java:org.netbeans.modules.javahelp.BrowserDisplayer"><param name="content" value="http://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/src/networking/com/jme3/network/serializing/serializers/GZIPSerializer.java"><param name="text" value="<html><u>the GZIPSerializer class</u></html>"><param name="textColor" value="blue"></object>.
