  move/lookat - need to pause renderer  (Read 698 times)

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

move-lookat-move-lookat-move-.....

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

move-render-lookat-render-move-render-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:

Render:

   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.
