      jMonkeyEngine is a modern developer friendly game engine written primarily in Java. 
      <br />
      Its minimalistic and code first approach makes it perfect for developers who want the support of a game engine
      while retaining full control over their code with the ability to extend and adapt the engine to their workflow.

</figure> I started learning jME back in the 3.0 days, as I recall,<br>
and I was impressed with the features it offered.<br>
The scene-graph control and appstate design made a lot of sense to me &mdash;<br>
at the time both were novel concepts.</p>
<p>Not long after that, I adopted jME for a project called “OpenWorld.”</p>

</figure> I first heard of them from<br>
a magazine article about Second Life, over a decade ago.<br>
I was fascinated, and despite being underage<br>
(accounts were restricted to users 18 and over), I created an account.</p>
<p>Since I was underage my adventures there did not last long, but<br>
I was hooked from the start.<br>
It was like a game, but there were so many things to do and places to explore,<br>
and the built-in creation system blew my mind.</p>
<p>A couple years later, I discovered OpenSimulator,<br>
an open-source server that’s compatible with Second Life clients (viewers).<br>
Since then, I’ve been a member of various OpenSimulator virtual worlds (or grids, as they’re called).</p>
<p>During my second year in OpenSimulator, I began to keenly notice<br>
some limitations that OpenSimulator inherited from Second Life.<br>
Compared to multi-player games, virtual worlds always felt slow and bloated,<br>
and the architecture was fundamentally limiting.</p>
<p>At that point I had the idea that grew into MyWorld:<br>
apply multiplayer game technology to social virtual worlds.<br>
Later on, I realized that a social virtual-world platform<br>
could also be a powerful MMO gaming platform, and<br>
since then I’ve worked towards the dual goal of supporting<br>
social virtual worlds and MMO games as first-class citizens on MyWorld.</p>

We see this as an advantage, for two reasons:</p>
<ol>
<li>We’re not beholden to shareholders,<br>
so we’re free to make decisions that bring the best experience to our users.</li>
<li>Our runway is infinitely long &mdash; we have no pressure to grow rapidly to avoid bankruptcy.<br>

Specifically, how would you compare it to Minecraft and Second Life?</p>

</figure> Unlike Minecraft, MyWorld is not a game itself &mdash;<br>
it’s a platform that supports dynamic content creation and scripting,<br>
and unlike games more generally, MyWorld provides first-class support<br>
for uploading 3D models, textures, audio, etcetera<br>
and distributing them to clients on an as-needed basis.<br>
It also has a professional-grade scripting language you can use<br>
to add custom behavior to your creations.</p>
<p>Unlike current-generation virtual worlds,<br>
MyWorld was designed from Day One to satisfy<br>
the performance requirements of multiplayer action games.<br>
This means that exploring a virtual world can have the same fast,<br>
fluid feel as playing a well-designed multiplayer game.</p>
<p>Another difference is that we support scripting on both client and server,<br>
allowing scripted effects and latency-elimination techniques<br>
that are impossible in current virtual worlds.</p>
<p>In addition, our internal systems can be extended via plugins<br>
that can integrate into the entity system and<br>
host or call HTTP endpoints (for custom REST APIs, for example).<br>
Plugins can even extend the core network protocol<br>
with jME’s fast, intuitive, and efficient RMI implementation.</p>

</figure> Our vision for MyWorld has always been to release it open-source,<br>
so the client will always be free to download and use, as will the core server.<br>
We may eventually release some commercial plugins for professional use,<br>
but these would be extensions to the core server,<br>
not permanently built-in proprietary code.</p>
<p>In a project like MyWorld,<br>
there are many opportunities to provide value to users,<br>
so there are many potential revenue streams.<br>
Initially we’re looking at a revenue model similar to Second Life:<br>
users can rent space in the virtual world to build homes,<br>
businesses, workshops, etcetera.<br>
We may also introduce a subscription model that offers<br>
extra benefits to heavy users.</p>
<p>We’re also investigating how we can monetize<br>
by offering professional hosting and support services to game developers<br>
and those interested in running MyWorld servers.</p>

</figure> While MyWorld needs a virtual currency to effectively operate,<br>
issuing one ourselves is not currently a viable choice for a couple of reasons:</p>
<ol>
<li>
<p>Issuing in-house currency is a large financial liability &mdash;<br>
there are many ways to destabilize an economy, virtual or otherwise,<br>
that are largely or completely outside the control of the currency issuer,<br>
which would present a risk both to us and our users.</p>
</li>
<li>
<p>Governments have begun regulating virtual currencies,<br>
making it expensive and difficult to issue them.</p>
</li>
</ol>
<p>Fortunately, we’re not the only ones with this need<br>
and there are several good virtual currency services,<br>
some of which allow the same currency to be used across many games or virtual worlds.</p>
<p>So yes, we will have a virtual currency,<br>
but we’re not planning on issuing it ourselves.</p>

</figure> Initially yes, unfortunately.<br>
Allowing minors requires extra legal compliance<br>
and stringent moderation of content and user interactions.</p>
<p>I don’t see this as a notable limitation, especially early on.<br>
Most of our initial user base will be developers and creators,<br>
not general users,<br>
so I expect the overwhelming majority of interest to be coming from adults.</p>
<p>I want to allow minors to access at least some areas within MyWorld<br>
as soon as it makes sense for us as an organization and community,<br>

</figure> Chipmunk was born out of necessity.</p>
<p>Like Second Life,<br>
MyWorld allows content creators to script anything they create.<br>
Scripting can include physics, movement, particle/sound/animation effects,<br>
HTTP calls, etcetera.</p>
<p>The problems here are security and resource use.<br>
Since anyone with creation privileges can upload scripts to a server<br>
(and scripts can also run client side), sandboxing is a must.</p>
<p>My first choice for scripting was Groovy.<br>
It’s a powerful, well-known language with many features,<br>
and the compiler supports AST transformations for customizing compiled code.<br>
I spent a great deal of time pursuing this route,<br>
but the shoe always pinched in the same spots: preemption and checkpointing.</p>
<p>Preemption means that the script engine can stop a running script at any time.<br>
This is necessary to ensure that misbehaving (or resource-intensive) scripts<br>
don’t overuse CPU resources.<br>
Preemption is also necessary for checkpointing:<br>
freezing a script so it can be persisted to disk or sent to another server.</p>
<p>Java was not designed for preemption.<br>
Every mechanism I could think of to fit preemption support<br>
into Java’s compiled bytecode came with substantial overhead and other nasty limitations.</p>
<p>I also experimented with an assembly-like language for scripting,<br>
but it was too difficult to read to be suitable for anything more than trivial scripts.</p>
<p>I designed Chipmunk to fit a unique place in the language spectrum &mdash;<br>
easy for a first-time programmer to pick up,<br>
but powerful enough for an experienced developer to hit the ground running.<br>
For example, classes declare state that’s shared between all instances<br>
via the “shared” keyword,<br>
which is semantically identical to Java’s “static” keyword,<br>
but expresses the concept in terms that make intuitive sense<br>
to inexperienced programmers.</p>
<p>In terms of features, Chipmunk supports modules, classes, polymorphism,<br>
first-class functions, anonymous (lambda) functions, exceptions,<br>
and dynamic typing.</p>

<p>What audio formats will MyWorld support?</p>

</figure> MyWorld is built around the assumption that users will create digital content.<br>
One of the first things I wrote was the dynamic asset upload/download mechanism.</p>
<p>Our initial creation pipeline is based around the GLTF format.<br>
Thanks to jME’s GLTF importer, most modern GLTF files should import seamlessly.<br>
Our primary interest in external tools is Blender 3D,<br>
but anything that exports to GLTF should do fine.</p>
<p>Later on, we plan to support in-world creation via constructive solid geometry<br>
with procedural extensions, as a supplement to the GLTF pipeline.</p>
<p>Any audio format supported by jME (OGG &amp; WAV in particular)<br>
can be opened by the client for upload.<br>
Streaming media can be in any format supported by JavaFX’s media framework.</p>
