Thanks !, the example of the bridge is good but when you press 1 for breaking the bridge in half, the behavior is strange when it hits the wall is very rigid.
I guess you could get with the physical library but I meant to do without the library.
The game is Castlevania of super nes.
Do you plan to break it up?
If you dont want to use the Physics Behavior (a behavior like any other behavior to simplify movements) then you can still just program the movements. One by one, event by event.
I was about to make you an example, but without using behaviours, i am not really interrested.
