Up To Date physics library w/collision masks for Go

<p>Are there any? The physics libraries that i can find (all chipmunk2d bindings) are several years out of date.</p> <hr/>**评论：**<br/><br/>Sythe2o0: <pre><p>There was a chipmunk2d binding set released a couple weeks ago, I assume it isn&#39;t out of date but I don&#39;t actually know: <a href="https://github.com/jakecoffman/cp" rel="nofollow">https://github.com/jakecoffman/cp</a></p> <p>There was also a box2d binding released around the same time, but I don&#39;t know if it satisfies what you&#39;re looking for: <a href="https://github.com/ByteArena/box2d" rel="nofollow">https://github.com/ByteArena/box2d</a></p></pre>moonheart08: <pre><p>thats not a chipmunk2d binding... thats a <em>port</em></p> <p>Even better. Thanks.</p></pre>Sythe2o0: <pre><p>Right, so is the box2d, sorry I wasn&#39;t thinking about terminology</p></pre>moonheart08: <pre><p>No need to apologize. a <em>Port</em> is always better than a binding (usually)</p></pre>
