liming, The solution is simple. It is true: the only thing that can be added to a live scene is a branch group. But that is not as restrictive as it may seem at first because you can add anything to the branchgroup while it is still not live and then add the branch group to the live scene. So, assuming you have set the correct capabilities on your avatar, you can add a behavior to the avatar by attaching the behavior to an unlive branchgroup and then attaching the branchgroup to the avatar. required capabilities are: Group.ALLOW_CHILDREN_EXTEND, Group.ALLOW_CHILDREN_WRITE, Group.ALLOW_CHILDREN_READ Raffi -----Original Message----- From: Liming CHEN [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 30, 2001 2:01 PM To: [EMAIL PROTECTED] Subject: [JAVA3D] add behaviour to a live scene Hi, Is it possible to add a behaviour to a live scene? This problem comes from: I create an avatar and make it live in the virtual world , then later through interface (button or menu) I would like to add some behaviour to the avatar. I have tried it but there is a message displaying that "RestrictedAccessException - only a BranchGroup node can be added". I can create a static avatar without behaviour and the same avatar with behaviour; First show the static avatar, when we want to show some behaviour of the avatart. Wwe detach the static avatar and add another BranchGroup containing the behavioring avatar. However, I think there should be a direct way that an avatar can act directly from static posture. Can anyone give a clue? thanks liming =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
