- Flushing Areas before anything else. - Make sure to correctly fetch gravity when the integrate_forces function is used - Lazy reload body when layer and mask changes - Shapes are reloaded just before the physics step starts. - Improved some other parts of the code. - Added override keyword - Using LocalVector
