  move/lookat - need to pause renderer  (Read 913 times)

I move my object, and then I set the view to look at it, and then I do it all over again.


My problem is that the render thread manages to render the scene between move and lookat


This gives the effect of that the object is shaking.

How do I solve this? Is there any pause/unpause on the render thread??

-- Edit --
View.setMinimumFrameCycleTime()  seem to have done the trick, is there any more sofisticated way?

You need to use behaviours. If you just want a single hook you can simple put a behaviour that wakes up every frame at the top of your scenegraph.

Then each render what'll happen is:


   Do what ever the behaviour tells you to do
   Render scene

In that behaviour you can just put a call out into your main logic handling classes.

Na, very easy. Just another scenegraph node that wakes up when you tell it to. The only gotcha I ever noticed was that you need to reschedule waking up once you've completed your action. Can't remember the method names but its something like this:

clazz LogicBehaviour extends Behaviour {
 init() {
   schedule wake up next frame

 wakeUp() {
   do your logic here
   schedule wake up next frame

I kept forgetting to put the second schedule in.
