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.
read-only
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.
