Swift：在不同场景中更新变量

我的游戏场景中有一个变量，它是score变量，它用SKLabelNode显示在屏幕上

每次发生冲突时，都会将1添加到score，并将其作为字符串传输到SKLabelNode，然后在屏幕上更新

问题是，当我从GameOverScene（最终分数与“game over”（游戏结束）一起显示的场景）调用它时，我得到分数的第一个值，即0。像GameOverScene一样，正在读取变量，但不是更新的变量。 如何获取更新的变量？有人能帮忙吗

代码：

class GameScene: SKScene, SKPhysicsContactDelegate {
    // S C O R E !
    var score = 0
    var scoreText: String = ""

    var scoreOnScreen = SKLabelNode()
...

override func didMoveToView(view: SKView) {
    // S C O R E
    scoreOnScreen.position = CGPoint(x: size.width / 2, y: size.height * 0.8)
    scoreText = String(score)
    scoreOnScreen.text = scoreText

发生碰撞时，得分为get的+1

func bulletDidCollideWithEnemy(enemy: SKSpriteNode, bullet: SKSpriteNode) {

        score++
        scoreText = String(score)
        scoreOnScreen.text = scoreText

然后，游戏场景：

import SpriteKit
import UIKit

class GameOverScene: SKScene {

    let GameSceneInstance = GameScene()
    let bgImage = SKSpriteNode(imageNamed: "background")
    let afraidLogo = SKSpriteNode(imageNamed: "gameoverlogo")
    var gameOverLabel = SKLabelNode()

    override func didMoveToView(view: SKView) {

        GameSceneInstance.scoreOnScreen.text = String(GameSceneInstance.score)

        bgImage.position = CGPoint(x: size.width / 2, y: size.height / 2)
        bgImage.setScale(0.75)
        addChild(bgImage)

        afraidLogo.position = CGPoint(x: size.width / 2, y: size.height / 2)
        afraidLogo.setScale(0.50)
        addChild(afraidLogo)

        gameOverLabel.fontSize = 40
        gameOverLabel.fontColor = SKColor.whiteColor()
        gameOverLabel.text = "score: \(GameSceneInstance.scoreOnScreen.text)"
        gameOverLabel.position = CGPointMake(self.size.width/2, 2.0 / 3.0 * self.size.height);
        addChild(gameOverLabel)

    }

class GameOverScene: SKScene {

    var gameScene = GameScene()
override func didMoveToView(view: SKView) {
   gameOverLabel.text = "score: \(gameScene.score)"

我打赌这只是代码的一个简单问题。感谢您的帮助。

我是在一个昵称为贾萨默的reddit人的帮助下想出这个主意的。盖伊摇滚

以下是我所改变的：

当场景被改变时

let scene = GameOverScene(size: skView.bounds.size)

我补充说：

    scene.gameScene = self
    scene.score = score

然后，游戏场景：

import SpriteKit
import UIKit

class GameOverScene: SKScene {

    let GameSceneInstance = GameScene()
    let bgImage = SKSpriteNode(imageNamed: "background")
    let afraidLogo = SKSpriteNode(imageNamed: "gameoverlogo")
    var gameOverLabel = SKLabelNode()

    override func didMoveToView(view: SKView) {

        GameSceneInstance.scoreOnScreen.text = String(GameSceneInstance.score)

        bgImage.position = CGPoint(x: size.width / 2, y: size.height / 2)
        bgImage.setScale(0.75)
        addChild(bgImage)

        afraidLogo.position = CGPoint(x: size.width / 2, y: size.height / 2)
        afraidLogo.setScale(0.50)
        addChild(afraidLogo)

        gameOverLabel.fontSize = 40
        gameOverLabel.fontColor = SKColor.whiteColor()
        gameOverLabel.text = "score: \(GameSceneInstance.scoreOnScreen.text)"
        gameOverLabel.position = CGPointMake(self.size.width/2, 2.0 / 3.0 * self.size.height);
        addChild(gameOverLabel)

    }

class GameOverScene: SKScene {

    var gameScene = GameScene()
override func didMoveToView(view: SKView) {
   gameOverLabel.text = "score: \(gameScene.score)"

它是有效的

我认为主要的问题是没有设置

scene.GameScene=self

我希望有一天这能帮助别人
