Joint class abstract Physics

A constraint between this node's RigidBody and otherNode's (or the world, when otherNode is null).

Add after both bodies. Property setters reconfigure the live joint.

Constructors

collisionsEnabled ↔ bool: Whether the joined bodies still collide with each other.
getter/setter pair
enabled ↔ bool: Whether this component's update hook runs each frame.
getter/setter pairinherited
handle → int?: The joint's simulation handle, or null while unmounted.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isAttached → bool: Whether this component is currently attached to a node.
no setterinherited
isLoaded → bool: Whether onLoad has completed.
no setterinherited
isMounted → bool: Whether the owning node is part of a live scene graph.
no setterinherited
node → Node: The node this component is attached to.
no setterinherited
otherNode → Node?: The body on the other side, or null to anchor against the world.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
world → PhysicsWorld?: The owning world while mounted.
no setter

buildDesc(int bodyA, int bodyB, bool collisionsEnabled) → JointDesc: Builds the description for the current property values.
cloneFor(Node cloneOwner) → Component?: Returns a copy of this component for cloneOwner, the Node.clone counterpart of the owning node, or null to not carry the component to clones (the default).
inherited
fixedUpdate(double fixedDt) → void: Called once per fixed physics step while the component is mounted, enabled, and loaded. fixedDt is the fixed timestep of the surrounding PhysicsWorld, not the frame interval.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onAttach() → void: Called when this component is added to a node.
inherited
onDetach() → void: Called when this component is removed from a node.
inherited
onLoad() → Future<void>: Optional asynchronous setup, such as loading an asset.
inherited
onMount() → void: Called when the owning node enters a live scene graph.
override
onUnmount() → void: Called when the owning node leaves a live scene graph.
override
push() → void: Reconfigures the live joint after a property change.
toString() → String: A string representation of this object.
inherited
update(double deltaSeconds) → void: Called once per frame while the component is mounted, enabled, and loaded. deltaSeconds is the elapsed time since the previous tick.
