spriteKit 一些功能总结

1.初始化窗口

orride func viewDidLoad() {
  super.viewDidLoad()
  if let view = self.view as! SKView? {
  //用来加载自己的页面
    let scence = FirstScence(size:view.bounds.size)
            scence.scaleMode = .AspectFill
            //页面跳转
            view.presentScene(scence)
            
  }
}

2.创建文本

//SKLabelNode
let myLabel = SKLabel.init()
myLabel.text = "hello"
self.addChild(myLabel)

3.添加动作

//SKAction
let moveSequence = SKAction.sequence([])

4.界面跳转

self.view?.presentScence(scence);

5.获取当前位置

var x = myLabel.postion.x
var y = myLabel.postion.y

6.物体碰撞
spriteKit有自己的碰撞识别方法，我们只需要实现代理即可
SKPhysicsContactDelegate

override func didMoveToView(view: SKView) {
   //     
  self.physicsWorld.contactDelegate = self
        A.physicsBody?.categoryBitMask = 1
        A.physicsBody?.categoryTestBitMask = 2
        B.physicsBody?.categoryBitMask = 2
        B.physicsBody?.categoryTestBitMask = 1
    }
//发生碰撞调用
func didBeginContact(contact:SKPhysicsContact) {

}

7.删除

myLabel.romoveFromParent()
