You can have the bullet behavior bounce off solids, but the physics behavior needs the other objects to have physics to work. The physics behavior will give more realistic bounces though. The third option would be to do your own physics with events, but this isn't by any means simple.
The problem is that with bullet behaviour the sprite move towards the rotation angle, so i can't make the ball moves, bounce and give them some sprite rotation depending of the velocity because this will change the real direction.
I mean, actually with physics i give the ball impulse to move/bounce and give the sprite some rotation depending of the velocity and works correctly.
So or there is any form to use the Bullet behaviour to move, bounce and rotate the sprite without this affect to the direction angle of the movement or i use 2 sprites, one that moves and bounce and set invisible and the sprite ball every tick in the same position giving rotation depending of the speed. But with the last one i will have to create/use 2 sprites for every thing i want to make the same effect.
Create my own physics well, i'm a noob i only have a few days of experience on C2 so not .
