Say I want to apply an impulse to an object relative to the position of the mouse cursor. For example I click the mouse creating an explosion at the mouse x and y and the object moves away in the proper direction. What should I be using for the last 2 parameters of SetSpritePhysicsImpulse? I have the mouse coords converted to world space for the location of the impulse and am using those for the first 2 parameters but I have no idea what I should be using for the second 2.

EDIT: I basically want to create an impulse from the mouse x, y to my objects x, y

Also, SetSpritePhysicsVelocity() might work better for you
