blaze.dynamics.joints.mouseJoint

class MouseJointDef : blaze.dynamics.joints.joint.JointDef;

Mouse joint definition. This requires a world target point,

tuning parameters, and the time step.

this(Body body1, Body body2);

Initialize the body and target point

bVec2 target ;

The initial world target point. This is assumed

to coincide with the body anchor initially.

float maxForce ;

The maximum constraint force that can be exerted

to move the candidate body. Usually you will express

as some multiple of the weight (multiplier * mass * gravity).

float frequencyHz ;

The response speed.

float dampingRatio ;

The damping ratio. 0 = no damping, 1 = critical damping.

class MouseJoint : blaze.dynamics.joints.joint.Joint;

A mouse joint is used to make a point on a body track a

specified world point. This a soft constraint with a maximum

force. This allows the constraint to stretch and without

applying huge forces.

bVec2 anchor1 ();

Implements b2Joint.

bVec2 anchor2 ();

Implements b2Joint.

bVec2 reactionForce (float inv_dt);

Implements b2Joint.

float reactionTorque (float inv_dt);

Implements b2Joint.

void setTarget (bVec2 target);

Use this to update the target point.
