SpriteKit를 통한 화면 마이그레이션

코드

최초 화면을 담당하는 HopScene class를 쓰도록 하겠습니다.

import SpriteKit

class HopScene: SKScene{
    override func didMoveToView(view: SKView) {
//この画面に来たときにHopって書いてあるラベルを配置
        let label = SKLabelNode()
        label.text = "Hop"
        label.position = CGPoint(x:100,y:70)
        self.addChild(label)        
    }

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        if let _ = touches.first as UITouch? {
//タッチを検出したときにStepSceneを呼び出す
            let scene = StepScene(size: self.scene!.size)
            scene.scaleMode = SKSceneScaleMode.AspectFill
            self.view!.presentScene(scene)

        }
    }
}

JumpScene class 만들기

import SpriteKit

class StepScene: SKScene{
    override func didMoveToView(view: SKView) {
        let label = SKLabelNode()
        label.text = "Step"
        label.position = CGPoint(x:100,y:70)
        self.addChild(label)
    }

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        if let _ = touches.first as UITouch? {
            let scene = JumpScene(size: self.scene!.size)
//呼び出すSceneをJumpScene classにしただけ
            scene.scaleMode = SKSceneScaleMode.AspectFill
            self.view!.presentScene(scene)
        }
    }
}

import SpriteKit

class JumpScene: SKScene{
    override func didMoveToView(view: SKView) {

        let label = SKLabelNode()
        label.text = "Jump"
        label.position = CGPoint(x:100,y:70)
        self.addChild(label)

    }

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        if let _ = touches.first as UITouch? {
            let scene = HopScene(size: self.scene!.size)
            scene.scaleMode = SKSceneScaleMode.AspectFill
            self.view!.presentScene(scene)
        }
    }
}

ViewController.swift에서 최초의 SKScene class를 부르다

import UIKit
import SpriteKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        //HopSceneを呼ぶ
        let view = self.view as! SKView
        let scene = HopScene()
        scene.size = view.frame.size
        view.presentScene(scene)
    }
}
