swiftでspritekit

swiftのスプライトキットのサンプルになれば。
やってること
・イメージを取り込んで、物理特性を持たせる
・ボタンクリックでイメージをジャンプさせる

ほとんどobjective-cと変わらないですね。

import SpriteKit

class GameScene: SKScene {

    let Jump : CGFloat = 400.0
    let imageWidth : CGFloat = 30.0
    let FloarWidth : CGSize = CGSizeMake(500, 500)

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */
        let iorin = SKSpriteNode(imageNamed:"minase-iori0020")

        iorin.xScale = 0.1
        iorin.yScale = 0.1
        iorin.position = CGPoint(x:CGRectGetMidX(self.frame),y:CGRectGetMidY(self.frame));
        iorin.name = "iori"

        let body = SKPhysicsBody(circleOfRadius:imageWidth)
        iorin.physicsBody = body

        self.addChild(iorin)

        let floor = SKSpriteNode(imageNamed:"minase-iori0020")
        floor.xScale = 0.3
        floor.yScale = 0.3
        floor.position = CGPoint(x:CGRectGetMidX(self.frame),y:CGRectGetMinY(self.frame));
        floor.name = "floor"

        let body2 = SKPhysicsBody(rectangleOfSize:FloarWidth)
        body2.affectedByGravity = false
        body2.dynamic = false
        body2.contactTestBitMask = 1
        floor.physicsBody = body2

        self.addChild(floor)
    }

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        /* Called when a touch begins */
        self.childNodeWithName("iori").physicsBody.velocity.dy = Jump
    }

    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame is rendered */
        self.childNodeWithName("floor").position =CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMinY(self.frame));
    }
