First of all, libgdx is a great and amazing android engine, I love it, I used
it for my 2d game development now I want to walk into 3d, I test the examples
that is very nice when loading .g3d model, but I met some problems when load
md2 models
What steps will reproduce the problem?
1. I follow the steps and modify the KeyframedModelViewer.java as
http://code.google.com/p/libgdx-users/wiki/MD2_Keyframe_Animation#Implement_MD2_
in_Game mentioned
2. then I got the error:
Exception in thread "AWT-EventQueue-0"
java.lang.ArrayIndexOutOfBoundsException: 2160
at com.badlogic.gdx.graphics.g3d.model.keyframe.KeyframedModel.setAnimation(KeyframedModel.java:150)
at com.badlogic.gdx.graphics.g3d.test.KeyframedModelViewer.render(KeyframedModelViewer.java:131)、
the code are there
final float valSrc = src[srcIdx];
final float valSrc2 = src2[srcIdx++];
I 've no idea with what's wrong with the logic, because it works well for g3d
models...
What is the expected output? What do you see instead?
To load md2 without any errors
What version of the product are you using? On what operating system?
the latest version of svn sources.
OS: windows 7
Please provide any additional information below.

I've tried the same code for g3d and .md2 and the code works if you follow the
instructions. One instruction missing is that when going for .md2 you need to
add an import to
import com.badlogic.gdx.graphics.g3d.materials.*;
and everything works, UNTIL,
you try to play animation other than default, which is 0("all")
anim = (KeyframedAnimation)model.getAnimations()[0];
The sam issue is with g3d animations. So both of us do not know how to start an
animation other than "all".
I tried my model animation exported from blender and there is the same issue.
If I play [0] animation, all is ok, but if I change it to other, say [2]
I get an error you are pointing out.

Hi,
i resolved the issue with ArrayIndexOutOfBoundsException problem when playing
selected parts of .md2 keyframe animation.
The workaround is somewhere around line 175 of file MD2Loader.java:
float[] vertices = new float[header.numVertices * 6]; // changed from *3 to *6
and
around line 182, added 3 lines for vertices:
vertices[idx++] = frame.vertices[idxV++];
vertices[idx++] = frame.vertices[idxV++];
vertices[idx++] = frame.vertices[idxV++];
I really hope this is not just a workaround, and that it's not going to create
some other issues :)
Hope this helps someone else...
