Support / Loading animation from a md2 file
« on: March 22, 2005, 11:49:52 pm »
Hello there, How are you?

Í'm beginning to work with JPCT and I'm having some problems to use animations from md2 files. I'm working with the tutorials for learning.

This is the code for loading the md2 file:
.
.
.
Object3D hombre=Loader.loadMD2("3d"+File.separator+"hombre.md2", 1f);
hombre.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS);
TextureManager.getInstance().addTexture("hombretex", new Texture("3d"+File.separator+"hombre.jpg"));
hombre.setTexture("hombretex");
hombre.setCenter(SimpleVector.ORIGIN);
hombre.translate(50, 0, 0);
hombre.build();
theWorld.addObject(hombre);

Animation anima=new Animation(61);
anima.createSubSequence("stand");
anima.addKeyFrame(hombre.getMesh().cloneMesh(true));
hombre.setAnimationSequence(anima);

theWorld.addObject(hombre);
.
.
.
private void gameloop() {
.
.
   while (!exit) {
            hombre.animate(0, 0);
            if (anim>1) {
               anim=0;
               } else {
               anim+=0.1f;
               }
.
.
.
But when I'm running the .class I get this error:

Can you help me to understand how to use the animations contained into a md2 file?
 :wink:
Thanks in advance.
