A Constraint that rotates a node to point towards another node. The target node is allowed to have a different parent, but they must be in the same SpriteBox.

Constructors

ConstraintRotationToNode(Node targetNode, { double baseRotation: 0.0, double dampening })

Creates a new Constraint that rotates the node towards the targetNode. The baseRotation will be added to the nodes rotation, and dampening can be used to ease the rotation.

Properties

baseRotation double

The base rotation will be added after the target rotation is calculated.

read-only
dampening double

The filter factor used when constraining the rotation of the node. Valid values are in the range 0.0 to 1.0

read-only
hashCode int

Get a hash code for this object.

read-only, inherited
runtimeType Type

A representation of the runtime type of the object.

read-only, inherited
targetNode Node

The node to rotate towards.

Operators

operator ==(other) bool

The equality operator.

Methods

constrain(Node node, double dt) → void

Called after update is complete, if the constraint has been added to a Node. Override this method to modify the node's property according to the constraint.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
preUpdate(Node node, double dt) → void

Called before the node's update method is called. This method can be overridden to create setup work that needs to happen before the the node is updated, e.g. to calculate the node's speed.

inherited
toString() String

Returns a string representation of this object.
