Joint class abstract

The base joint class. Joints are used to constrain two bodies together in various fashions. Some joints also feature limits and motors.

Implementers

Constructors

anchorA → Vector2: Get the anchor point on bodyA in world coordinates.
no setter
anchorB → Vector2: Get the anchor point on bodyB in world coordinates.
no setter
bodyA ↔ Body: getter/setter pair
bodyB ↔ Body: getter/setter pair
collideConnected → 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.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isActive → bool: Short-cut function to determine if either body is inactive.
no setter
islandFlag ↔ bool: getter/setter pair
localAnchorA → Vector2: final
localAnchorB → Vector2: final
renderColor → Color3i: Color used to render.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

containsBody(Body body) → bool: Whether the body is connected to the joint
destructor() → void: Override to handle destruction of joint
initVelocityConstraints(SolverData data) → void
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
otherBody(Body body) → Body: Get the other body than the argument in the joint
reactionForce(double invDt) → Vector2: Get the reaction force on body2 at the joint anchor in Newtons.
reactionTorque(double invDt) → double: Get the reaction torque on body2 in N*m.
render(DebugDraw debugDraw) → void
solvePositionConstraints(SolverData data) → bool: This returns true if the position errors are within tolerance. Internal.
solveVelocityConstraints(SolverData data) → void
toString() → String: A string representation of this object.
