![SKAction
・SKNodeの動きを作るやつ
->ノードの移動、回転、拡大縮小などの変化を作ることができる
・使い方は、作ったActionをnodeの持つrunAction
メソッドに渡すだけ
・連続的なActionも渡せるよ！
let action = SKAction.moveByX(…)
node.runAction(action)
let action1 = SKAction.moveByX(…)
let action2 = SKAction.moveByX(…)
let sequenceAction = SKAction.sequence([action1,action2])
node.runAction(sequenceAction)](https://image.slidesharecdn.com/spritekit-150706033917-lva1-app6891/85/Introduction-of-Swift-from-Game-Development-8-320.jpg)
![Step5 Swiftのちょっとした文法
class Grape:SKSpriteNode {
var hitCount:Int = 0
}
・クラスの継承
・データ構造
let grapesPosition:[(x:CGFloat,y:CGFloat)] = [(60.0,500.0),
(160.0,500.0),(260.0,500.0),(110.0,400.0),(220.0,400.0)]
配列、タプル
・繰り返し
//グレープの配置
for pos in grapesPosition{
makeGrape(pos)
}](https://image.slidesharecdn.com/spritekit-150706033917-lva1-app6891/85/Introduction-of-Swift-from-Game-Development-21-320.jpg)
![Step9 パーティクル
let particle = SKEmitterNode(fileNamed: "MyParticle.sks")
self.addChild(particle)
let removeAction = SKAction.removeFromParent()
let durationAction = SKAction.waitForDuration(1)
let sequenceAction = SKAction.sequence([durationAction,removeAction])
particle.runAction(sequenceAction)
particle.position = CGPoint(x: g.position.x, y: g.position.y)
particle.alpha = 1](https://image.slidesharecdn.com/spritekit-150706033917-lva1-app6891/85/Introduction-of-Swift-from-Game-Development-26-320.jpg)
