<p>In the <a href="../../tutorials/beginner/hello_collision.html" class="xref page">Hello Collision</a> tutorial and the <a href="https://github.com/jMonkeyEngine/jmonkeyengine/blob/master/jme3-examples/src/main/java/jme3test/bullet/TestQ3.java">TestQ3.java</a> code sample you have seen how to create collidable landscapes and walk around in a first-person perspective. The first-person camera is enclosed by a collision shape and is steered by the BetterCharacterControl.</p>
</div>
<div class="paragraph">
<p>Other games however require a third-person perspective of the character: In these cases you use a CharacterControl on a Spatial. This example also shows how to set up custom navigation controls, so you can press WASD to make the third-person character walk; and how to implement dragging the mouse to rotate.</p>

<h2 id="bettercharactercontrol"><a class="anchor" href="#bettercharactercontrol"></a>BetterCharacterControl</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Motivation: When you load a character model, give it a RigidBodyControl, and use forces to push it around, you do not get the desired behaviour: RigidBodyControl&#8217;ed objects (such as cubes and spheres) roll or tip over when pushed by physical forces. This is not the behaviour that you expect of a walking character. JME3&#8217;s BulletPhysics integration offers a BetterCharacterControl with a <code>setWalkDirection()</code> method. You use it to create simple characters that treat floors and walls as solid, and always stays locked upright while moving.</p>
</div>
<div class="paragraph">
<p>To use the BetterCharacterControl, you may load your character like this:</p>
</div>
<div class="listingblock">
<div class="content">
<pre class="highlightjs highlight"><code class="language-java hljs" data-lang="java">// Load any model
Spatial playerSpatial = assetManager.loadModel("Models/Oto/Oto.mesh.xml");
player =  (Node)playerSpatial; // You can set the model directly to the player. (We just wanted to explicitly show that it's a spatial.)
Node playerNode = new Node(); // You can create a new node to wrap your player to adjust the location. (This allows you to solve issues with character sinking into floor, etc.)
playerNode.attachChild(player); // add it to the wrapper
player.move(0,3.5f,0); // adjust position to ensure collisions occur correctly.
player.setLocalScale(0.5f); // optionally adjust scale of model
// setup animation:
control = player.getControl(AnimControl.class);
control.addListener(this);
channel = control.createChannel();
channel.setAnim("stand");
playerControl = new BetterCharacterControl(1.5f, 6f, 1f); // construct character. (If your character bounces, try increasing height and weight.)
playerNode.addControl(playerControl); // attach to wrapper
// set basic physical properties:
playerControl.setJumpForce(new Vector3f(0,5f,0));
playerControl.warp(new Vector3f(0,10,10)); // warp character into landscape at particular location
// add to physics state
bulletAppState.getPhysicsSpace().add(playerControl);
bulletAppState.getPhysicsSpace().addAll(playerNode);
// You can change the gravity of individual physics objects after they are
// added to the PhysicsSpace.
playerControl.setGravity(new Vector3f(0,-1f,0));

rootNode.attachChild(playerNode); // add wrapper to root</code></pre>
