Like patching of classes, you can also patch single objects. The difference is that only that one instance can use the new method. Example: Override a string object to provide parsing to boolean s = 'true' t = 'false' def s.to_b self =~ /true/ ? true : false end >> s.to_b =&...

A very simple example would be to fade out an SKSpriteNode. In Swift: let node = SKSpriteNode(imageNamed: "image") let action = SKAction.fadeOutWithDuration(1.0) node.runAction(action)

Sometimes it is necessary to do an action on repeat or in a sequence. This example will make the node fade in and out a total of 3 times. In Swift: let node = SKSpriteNode(imageNamed: "image") let actionFadeOut = SKAction.fadeOutWithDuration(1.0) let actionFadeIn = SKAction.fadeInWithD...

One helpful case is to have the action run a block of code. In Swift: let node = SKSpriteNode(imageNamed: "image") let actionBlock = SKAction.runBlock({ //Do what you want here if let gameScene = node.scene as? GameScene { gameScene.score += 5 } }) node.runActi...
