Hi,

I've got a problem using a WakeupCriterion. My scenegraph contains a
set of MorphBehaviors. Now I'd like them to invoke their
processStimulus() method if the control class says "lets go". But
which WakeUpCriterion should I use? I thought of WakeupOnAWTEvent, but
somewhere I read this works only with events like "Key_Pressed" and
not with an Action_Event. The best would be a boolean trigger var that
can be set to start the behavior's movement.

Thanks for helping me,
André

The problem is that you can't create your own wakeup conditions! I hit
that one. What I did was create a subclass of Behaviour, which can post
wakeup events (postId(int) ) and then use WakeupOnBehaviorPost. My
control class invoked a method on the subclass, which then woke up the
behaviour I wanted.

The nice thing about this was that I could then use any conditions I
liked, which would call the controller and which then posted the
appropriate ID, eg

class Controller extends Behavior {
...
void requestPost(int postIdToSend){
postId(postIdToSend;
}

AFAIK, the WakeupOnAWTEvent works with any AWT event, though I haven't
tried it.
