Re: [JAVA3D] Problems with Behavior

[Olivier Tassy]

Hi, I am doing the same thing and it works well with these settings: for shape3D (to declare in the branchgroup where they are):                     node.setCapability(Shape3D.ALLOW_GEOMETRY_READ);                     node.getGeometry().setCapability(Geometry.ALLOW_INTERSECT);                     node.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);                     node.setCapability(Shape3D.ALLOW_APPEARANCE_READ); and  for the branchgroup:                     branchgroup.setCapability(Node.ENABLE_PICK_REPORTING);   bye.

Unfortunately I keep getting a CapabilityNotSetException:   Exception occurred during Behavior execution: javax.media.j3d.CapabilityNotSetException: Shape3D: no capability to get appearance     at javax.media.j3d.Shape3D.getAppearance(Shape3D.java:430)     at ids.java3d.HatColourBehavior.updateScene(HatColourBehavior.java:55)     at com.sun.j3d.utils.picking.behaviors.PickMouseBehavior.processStimulus(PickMouseBehavior.java:153)     at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:167)     at javax.media.j3d.J3dThread.run(J3dThread.java:256)   The failure occurs when trying to execite the getAppearance() method. The thing is, as far as I know, I *have* set the capability. The code I'm using to create the object is:   MagicHat hat = new MagicHat(); hat.setPickable(true); hat.setCapability(Node.ENABLE_PICK_REPORTING); hat.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE); hat.setCapability(Shape3D.ALLOW_APPEARANCE_READ);   I even went into the MagicHat class (which extends Shape3D and consists of two Cylinders) and set ENABLE_APPEARANCE_MODIFY on the two Cylinders.   Any ideas what I'm doing wrong? Am I missing something really obvious?   Thanks, Matt
