Question

我目前正在开发一款由三个场景组成的游戏，GameScene，ArcheryScene和GameOverScene。当我开始游戏时GameScene呈现得很好，然后我点击屏幕开始游戏，ArcheryScene呈现得很好。 GameOverScene会在游戏中建立联系时触发，并且也可以。然而，一旦呈现GameOverScene，我希望能够点击屏幕返回ArcheryScene并重新开始游戏。然而，当我点击屏幕时，根本没有任何反应。任何建议或建议都将非常感谢，谢谢。

GameScene Code在点击时显示ArcheryScene :(有效）

import UIKit
import SpriteKit

class GameScene: SKScene {

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */

    }

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        /* Called when a touch begins */

    let welcomeNode = childNodeWithName("welcomeNode")

        if (welcomeNode != nil) {
            let fadeAway = SKAction.fadeOutWithDuration(1.0)

            welcomeNode?.runAction(fadeAway, completion: {
                let doors = SKTransition.pushWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let archeryScene = ArcheryScene(fileNamed: "ArcheryScene")
                archeryScene.scaleMode = .AspectFill
                self.view?.presentScene(archeryScene, transition: doors)
            })
        }

    }

    override func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
    }
}

ArcheryScene代码，用于在联系人时显示GameOverScene :(有效）

let fadeOut = SKAction.sequence([SKAction.waitForDuration(3.0)])
            let welcomeReturn = SKAction.runBlock({
                let Transition = SKTransition.revealWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let gameOverScene = GameScene(fileNamed: "GameOverScene")
                gameOverScene.scaleMode = .AspectFill
                self.scene!.view?.presentScene(gameOverScene, transition: Transition)
            })
            let sequence = SKAction.sequence([fadeOut, welcomeReturn])
            self.runAction(sequence)

GameOverSceneCode在点击时显示ArcheryScene :(不起作用）

import UIKit
import SpriteKit

class GameOverScene: SKScene {

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */

    }

   override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        /* Called when a touch begins */

        let gameOverNode = childNodeWithName("gameOverNode")

        if (gameOverNode != nil) {

            let fadeAway2 = SKAction.fadeOutWithDuration(1.0)

            gameOverNode?.runAction(fadeAway2, completion: {
                let doors2 = SKTransition.pushWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let archeryScene = ArcheryScene(fileNamed: "ArcheryScene")
                archeryScene.scaleMode = .AspectFill
                self.view?.presentScene(archeryScene, transition: doors2)
            })
        }

    }

    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame is rendered */
    }
}

Answer 1

gameOverNode不存在。你说let gameOverNode = childNodeWithName("gameOverNode") .. gameOverNode是零！它什么都没有，所以条件语句中的代码块没有做任何事情。

您需要添加名为“gameOverNode”的节点才能引用它。 childNodeWithName引用场景中已存在的节点..它不会创建新节点。

Sprite Kit场景不会出现
