The standard tool for updating a node's worldBound is using updateGeometricState(0,true).
Problem with this is that all controllers are called (with time 0) and if you don't catch that
your controllers might be called too often. For that I added a possibility for nodes to update
the whole subtree's worldboundings before. (Of course you have to use updateWolrdVectors(true) before and propagateBoundToRoot() after inorder to have the same effect as the updategeometricstate(…) )
Now you can update the worldboundings inside the controller without being forced to use the GameTaskManager as well.
This is the patch:
