Er I've bumped into a weird (maybe not) problem.
I've made a Sprite with a Physics Behavior. All is cool, it falls and collides with a ground Solid object.
Now I want the Sprite to change Size as it rolls on the ground but as soon as I put a Sine behavior (to have it grow), my Sprite looses apparently its Physics Behavior (it doesn't fall, it just stays there on screen with it's size pulsing).
As soon as I remove the Sine (or any Scale animation), it falls again on the ground as expected...
Am I doing something wrong?
I want to have an animation of a snowball rolling (with Physics) and growing bigger as time passes.
