Access to Sprite Kit, a library for animation and physics.
Remarks
Sprite Kit is a library that provides a high-performance animation and physics loop. It is well-suited for 2D game programming and is available on both iOS and OS X.
The animation loop:
- The MonoTouch.SpriteKit.SKScene calls MonoTouch.SpriteKit.SKScene.Update.
- For each MonoTouch.SpriteKit.SKNode in its MonoTouch.SpriteKit.SKNode.Children, executes the child node's MonoTouch.SpriteKit.SKActions.
- The MonoTouch.SpriteKit.SKScene calls MonoTouch.SpriteKit.SKScene.DidEvaluateActions
- For each MonoTouch.SpriteKit.SKNode in its MonoTouch.SpriteKit.SKNode.Children, executes the child node's physics
- The MonoTouch.SpriteKit.SKScene calls MonoTouch.SpriteKit.SKScene.DidSimulatePhysics
The system restricts the animation loop to a maximum rate of 60Hz.
The visual aspect of the animation loop is determined by a scene-graph consisting of a hierarchy of MonoTouch.SpriteKit.SKNodes. The root of the scene-graph is a MonoTouch.SpriteKit.SKScene which itself is a MonoTouch.SpiteKit.SKNode (see illustration below). MonoTouch.SpriteKit.SKNodes can be rectangular, based on a MonoTouch.CoreGraphics.CGPath, or display text. MonoTouch.SpriteKit.SKNodes can be textured, colored, or display video. They can have MonoTouch.CoreImage.CoreFilters applied to them and can be composited.
MonoTouch.SpriteKit.SKNodes can have an associated MonoTouch.SpriteKit.SKPhysicsBody. All of the MonoTouch.SpriteKit.SKPhysicsBodys in the MonoTouch.SpriteKit.SKScene.PhysicsWorld of the MonoTouch.SpriteKit.SKScene are part of the physics loop. MonoTouch.SpriteKitSKPhysicsBodys are joined to each other with MonoTouch.SpriteKit.SKJoints, of which there are several sub-classes as shown in the following illustration.
