Collision question.

Is the collision pixel-perfect, evan when using scaling and rotation, and is it fast?

Thanks

The sample in the docs of BMax scales the Images.
So yes.

its prety fast but I would advise you try and use rect collision where possible

So could a metal slug type game with scaling and rotation be possible and would it be fast with paralax scrolling ect?

Yes if you optimize the collision handling a little this is possible without any problems.

On decent hardware, yes.

He's going to have fill rate problems well in advance of collision problems.

My FX-57 with 2x7800gtx's should be fast enough. :)
