Method Summary

static org.jbox2d.dynamics.joints.DistanceJoint	createDistanceJoint(org.jbox2d.dynamics.Body a, org.jbox2d.dynamics.Body b) Creates and returns a simple distance joint between two bodies, based on their world body positions (NOT their centers of mass).
static org.jbox2d.dynamics.joints.DistanceJoint	createDistanceJoint(org.jbox2d.dynamics.World w, org.jbox2d.common.Vec2 pA, org.jbox2d.common.Vec2 pB) Creates a distance joint between bodies that touch the given points, anchored at those points.
static org.jbox2d.dynamics.joints.RevoluteJoint	createRevoluteJoint(org.jbox2d.dynamics.Body a, org.jbox2d.dynamics.Body b, org.jbox2d.common.Vec2 worldCenter) Creates a RevoluteJoint between two bodies that rotates around a given point in World coordinates.

createDistanceJoint

public static org.jbox2d.dynamics.joints.DistanceJoint createDistanceJoint(org.jbox2d.dynamics.World w,
                                                                           org.jbox2d.common.Vec2 pA,
                                                                           org.jbox2d.common.Vec2 pB)

Creates a distance joint between bodies that touch the given points, anchored at those points. Returns null if there are not two different bodies at the points given. Behavior is undetermined if more than one body touches a point.

Parameters:

w - World to add joint to and read bodies from

pA - First point to attach to

pB - Second point to attach to

Returns:

Joint created, or null if impossible to create the joint

createDistanceJoint

public static org.jbox2d.dynamics.joints.DistanceJoint createDistanceJoint(org.jbox2d.dynamics.Body a,
                                                                           org.jbox2d.dynamics.Body b)

Creates and returns a simple distance joint between two bodies, based on their world body positions (NOT their centers of mass).

Parameters:

a -

b -

Returns:

a new DistanceJoint

createRevoluteJoint

public static org.jbox2d.dynamics.joints.RevoluteJoint createRevoluteJoint(org.jbox2d.dynamics.Body a,
                                                                           org.jbox2d.dynamics.Body b,
                                                                           org.jbox2d.common.Vec2 worldCenter)

Creates a RevoluteJoint between two bodies that rotates around a given point in World coordinates.

Parameters:

a -

b -

worldCenter -

Returns:
