SKAction Class

Definition

Modifies properties on a SKNode, often animating the changes. Sometimes reversible.

Remarks

Application developers use the static methods of SKAction to create actions that can be applied to the SKNodes of a SKScene. Generally, animations are animated.

The Group(SKAction[]), RepeatAction(SKAction, UIntPtr) and RepeatActionForever(SKAction), and Sequence(SKAction[]) methods are composite actions that take, as parameters, children SKActions.

Once a SKAction is created, application developers run it with the RunActionAsync(SKAction) method, as shown in this example:

var actions = SKAction.Group(
	new SKAction[] {
		SKAction.MoveBy(new CGVector(10, 10), 1),
		SKAction.FadeAlphaTo(0.3f, 1),
		SKAction.ScaleBy(0.8f, 1)
});

b.Node.RunAction(actions);          

Constructors

Name	Description

SKAction(NSCoder)	A constructor that initializes the object from the data stored in the unarchiver object.
SKAction(NSObjectFlag)	Constructor to call on derived classes to skip initialization and merely allocate the object.
