MilkshapeASCIIModel DeformationJointController

Troubleshooting General Help
1

In a MilkshapeASCIIModel that I’ve been able to load reliably, I’ve added a simple animation where one piece of it rotates. There are 360 frame and 1 joint.



When loading the model:



MilkshapeASCIIModel modelToLoad = new MilkshapeASCIIModel

(entityIdString);

modelToLoad.load(fileToLoad.toURL(),"…/textures");



DeformationJointController modelToLoadJointController =

(DeformationJointController)modelToLoad.getAnimationController();

modelToLoadJointController.setupJointAnimations();

modelToLoad.addController(modelToLoadJointController);





I get the following error:



INFO: Node created.

java.lang.ArrayIndexOutOfBoundsException: 4872

Are there any other steps I missed to get a MilkshapeASCIIModel animation to play in JME?



Thanks.

MilkshapeASCIIModel modelToLoad = new MilkshapeASCIIModel

(entityIdString);

modelToLoad.load(fileToLoad.toURL(),"…/textures");



alone should load the animations. You should not require a call to setup the deformation joint controller.



your code:



DeformationJointController modelToLoadJointController =

(DeformationJointController)modelToLoad.getAnimationController();

modelToLoadJointController.setupJointAnimations();

modelToLoad.addController(modelToLoadJointController);



was building an empty controller than replacing the filled controller. So when animation started, the array had zero elements.

I get the same error when only loading the model:



modelToLoad = new MilkshapeASCIIModel(entityIdString);

modelToLoad.load(fileToLoad.toURL(),"…/textures");

I may back off to a simpler model as a test case. Let me know if you have something I should try.



Thanks.

I had some vertices that were not assigned to a joint - everything seems to be working fine now.



Thanks.

You do bring up an interesting case. Your model worked fine in Milkshape, but crashed in jME. I guess we need to do a little work to make sure it can load models that have little "quirks" like that.
