Description
Applies an impulse at a point. This immediately modifies the velocity. It also
modifies the angular velocity if the point of application is not at the center of
mass. This wakes up the body.
b2.Body:applyLinearImpulse(impulsex,impulsey,pointx,pointy)
Parameters
impulsex: (number) the x coordinate of the world impulse vector, usually in N-seconds or kg-m/s
impulsey: (number) the y coordinate of the world impulse vector, usually in N-seconds or kg-m/s
pointx: (number) the x coordinate of the world position of the point of application
pointy: (number) the y coordinate of the world position of the point of application
