/** A Sprite subclass that is bound to a physics body.
|
|
It works with:
|
|
- Box2D
|
|
|
|
Features and Limitations:
|
|
- Scale and Skew properties are ignored.
|
|
- Position and rotation are going to updated from the physics body
|
|
- If you update the rotation or position manually, the physics body will be updated
|
|
- You can't enble both Chipmunk support and Box2d support at the same time. Only one can be enabled at compile time
