# ApplyLinearImpulse(Vector2, Vector2, bool)

> Apply an impulse at a point. This immediately modifies the velocity and also modifies the angular velocity if the point of application is not at the center of mass. This should be used for one-shot impulses. If you need a steady force, use a force instead, which will work better with the sub-stepping solver.
