On Controller.RT_CYCLE mode,
When BoneAnimation is updated through Node.updateWorldData(), it works well.
(in other words, updated by AnimationController attached to Node)
But if BoneAnimation is updated directly, it fails.
For the test, I modified "TestColladaLoading.java" like below
import java.io.InputStream;
import java.net.URISyntaxException;
import java.util.ArrayList;
import java.util.logging.Logger;

AnimationController ac;
boolean boneOn = false;

app.setDialogBehaviour(AbstractGame.ALWAYS_SHOW_PROPS_DIALOG);
app.start();
}
protected void simpleUpdate() {
if( KeyBindingManager.getKeyBindingManager().isValidCommand( "bones", false ) ) {
boneOn = !boneOn;
}
anim1.update(tpf, Controller.RT_CYCLE, 1f);
}
protected void simpleRender() {
//If we want to display the skeleton use the BoneDebugger.
if(boneOn) {
BoneDebugger.drawBones(rootNode, display.getRenderer(), true);
}
}
protected void simpleInitGame() {
try {
ResourceLocatorTool.addResourceLocator(
ResourceLocatorTool.TYPE_TEXTURE,
new SimpleResourceLocator(TestColladaLoading.class
.getClassLoader().getResource(
"jmetest/data/model/collada/")));
} catch (URISyntaxException e1) {
logger.warning("Unable to add texture directory to RLT: "
+ e1.toString());
}
KeyBindingManager.getKeyBindingManager().set( "bones", KeyInput.KEY_SPACE );
//Our model is Z up so orient the camera properly.
cam.setAxes(new Vector3f(-1,0,0), new Vector3f(0,0,1), new Vector3f(0,1,0));
cam.setLocation(new Vector3f(0,-100,20));
input = new FirstPersonHandler( cam, 80,
1 );
//this stream points to the model itself.
InputStream mobboss = TestColladaLoading.class.getClassLoader()
.getResourceAsStream("jmetest/data/model/collada/man.dae");
//this stream points to the animation file. Note: You don't necessarily
//have to split animations out into seperate files, this just helps.
InputStream animation = TestColladaLoading.class.getClassLoader()
.getResourceAsStream("jmetest/data/model/collada/man_walk.dae");
if (mobboss == null) {
logger.info("Unable to find file, did you include jme-test.jar in classpath?");
System.exit(0);
}
//tell the importer to load the mob boss
ColladaImporter.load(mobboss, "model");
//we can then retrieve the skin from the importer as well as the skeleton
SkinNode sn = ColladaImporter.getSkinNode(ColladaImporter.getSkinNodeNames().get(0));
Bone skel = ColladaImporter.getSkeleton(ColladaImporter.getSkeletonNames().get(0));
//clean up the importer as we are about to use it again.
ColladaImporter.cleanUp();
//load the animation file.
ColladaImporter.load(animation, "anim");
//this file might contain multiple animations, (in our case it's one)
ArrayList<String> animations = ColladaImporter.getControllerNames();
if(animations != null) {
logger.info("Number of animations: " + animations.size());
for(int i = 0; i < animations.size(); i++) {
logger.info(animations.get(i));
}
anim1 = ColladaImporter.getAnimationController(animations.get(0));
//set up a new animation controller with our BoneAnimation
ac = new AnimationController();
ac.addAnimation(anim1);
ac.setRepeatType(Controller.RT_CYCLE);
ac.setActive(false);
ac.setActiveAnimation(anim1);
//assign the animation controller to our skeleton
skel.addController(ac);
}
//attach the skeleton and the skin to the rootnode. Skeletons could possibly
//be used to update multiple skins, so they are seperate objects.
rootNode.attachChild(sn);
rootNode.attachChild(skel);
rootNode.updateGeometricState(0, true);
//all done clean up.
ColladaImporter.cleanUp();
lightState.detachAll();
PointLight pl = new PointLight();
pl.setAmbient(new ColorRGBA(0.5f,0.5f,0.5f,1));
pl.setDiffuse(new ColorRGBA(1,1,1,1));
pl.setLocation(new Vector3f(10,-50,20));
pl.setEnabled(true);
lightState.attach(pl);
}
}
I deactivated aniamtion controller and updated BoneAnimation on "simpleUpdate()" method
java.lang.ArrayIndexOutOfBoundsException: 30
at com.jme.animation.BoneAnimation.update(BoneAnimation.java:263)
at jmetest.TestColladaLoading.simpleUpdate(TestColladaLoading.java:44)
at com.jme.app.SimpleGame.update(SimpleGame.java:72)
at com.jme.app.BaseGame.start(BaseGame.java:79)
at jmetest.TestColladaLoading.main(TestColladaLoading.java:37)
I suggest that the conditions be modified
(BoneAnimation: line 263)
NOT while (currentTime >= keyframeTime[currentFrame]) {
BUT while (currentTime > keyframeTime[currentFrame]) {
(BoneAnimation: line 273 )
NOT while (currentTime <= keyframeTime[currentFrame]) {
BUT while (currentTime < keyframeTime[currentFrame]) {
I hope it helps
PS. I have one more question unrelated to this.
How can I embed the code to a box with scrollerbar like others do?? :?
