I have a problem using 2 different behaviours : one is listening for
MOUSE_MOVED and the other for WakeupOnElapsedTime(10000).
As far as i join only one of them at time to my BranchRoot , everything
works properly, but when i add them both , it happens that:
- as far as i do not move the mouse, the elapsedTimeB works properly.
When i move the mouse in the canvas , i get the following error message:
java.lang.NullPointerException:
at
javax.media.j3d.WakeupCriteriaEnumerator.reset(WakeupCriteriaEnumerator.java:73)
at
javax.media.j3d.WakeupCriteriaEnumerator.<init>(WakeupCriteriaEnumerator.java:36)
at
javax.media.j3d.BehaviorScheduler.processBehaviors(BehaviorScheduler.java:779)
at
javax.media.j3d.BehaviorScheduler.run(BehaviorScheduler.java:953)
I even do not understand what causes this error: maybe some conflict
between the 2 Behavs...
I hope someone may help me .
Thank you so much.
