MouseJoint class

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. NOTE: this joint is not documented in the manual because it was developed to be used in the testbed. If you want to learn how to use the mouse joint, look at the testbed.

Methods

getAnchorA(Vector2 argOut) → void
get the anchor point on bodyA in world coordinates. [...]
override
getAnchorB(Vector2 argOut) → void
get the anchor point on bodyB in world coordinates. [...]
override
getReactionForce(double invDt, Vector2 argOut) → void
get the reaction force on body2 at the joint anchor in Newtons. [...]
override
getReactionTorque(double invDt) double
get the reaction torque on body2 in N*m. [...]

getTarget() Vector2
initVelocityConstraints(SolverData data) → void
Internal
override
setTarget(Vector2 target) → void
solvePositionConstraints(SolverData data) bool
This returns true if the position errors are within tolerance. Internal.

inherited
getBodyA() Body
get the first body attached to this joint.
inherited
getBodyB() Body
get the second body attached to this joint. [...]
inherited
getCollideConnected() bool
Get collide connected. Note: modifying the collide connect flag won't work correctly because the flag is only checked when fixture AABBs begin to overlap.
inherited
getNext() Joint
get the next joint the world joint list.
inherited
getType() JointType
get the type of the concrete joint. [...]
inherited
isActive() bool
Short-cut function to determine if either body is inactive. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toString() String
Returns a string representation of this object.
