Apply a positioned impulse (which will be affected by the body mass and shape). This is the equivalent of hitting a billiard ball with a cue: a force that is applied once, and only once. Both the impulse and the position are in global coordinates, and the position is relative to the object's origin.
Applies a positioned impulse to the body. An impulse is time independent! Applying an impulse every frame would result in a framerate dependent force. For this reason it should only be used when simulating one-time impacts. The position uses the rotation of the global coordinate system, but is centered at the object's origin.

<description>
Applies a positioned impulse to the body (which will be affected by the body mass and shape). This is the equivalent of hitting a billiard ball with a cue: a force that is applied instantaneously. Both the impulse and the offset from the body origin are in global coordinates.
Applies a positioned impulse to the body. An impulse is time independent! Applying an impulse every frame would result in a framerate dependent force. For this reason it should only be used when simulating one-time impacts (use the "_force" functions otherwise). The position uses the rotation of the global coordinate system, but is centered at the object's origin.
