[quote="Azu":3f5rx2xi]How do I not have an background or object with out a box collision? I made a curve, yet it still has a box collision. Also, how do I rotate objects in the animation editor.[/quote:3f5rx2xi]
Under the sprite properties, set the collision to Per Pixel. I think it's in the Attributes section, but I'm not sure right now (posting from my Wii).
As for rotations, you can make new angles from the Animations bar, not in the picture editor.
