B2.Body:applyLinearImpulse

Available since: Gideros 2011.6
Class: b2.Body

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. <syntaxhighlight lang="lua"> b2.Body:applyLinearImpulse(impulsex,impulsey,pointx,pointy) </source>

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
