Question

我这里有一个结构，用于将函数传递给GameScene，我可以随时调用它。

问题是行GameScene.addChild(explosionFirst)生成以下错误：

'SKSpriteNode'无法转换为'GameScene'

我如何将其他类的节点添加到GameScene？

import Foundation
import SpriteKit

struct Explosion {

    var explosions = [SKTexture]()

    mutating func spawnExplosion(spawnPosition: CGPoint) {

        for i in 0...79 {
            let explosion = SKTexture(imageNamed: String(i))
            explosions.append(explosion)
        }

        let explosionFirst = SKSpriteNode(texture: explosions[0])
        explosionFirst.position = spawnPosition
        explosionFirst.zPosition = 1
        explosionFirst.setScale(5)

        GameScene.addChild(explosionFirst)

        let animation = SKAction.animate(with: explosions, timePerFrame: 0.1)

        let scaleIn = SKAction.scale(to: 10, duration: 2.3)
        let fadeOut = SKAction.fadeOut(withDuration: 1.0)
        let delete = SKAction.removeFromParent()

        let explosionSequence = SKAction.sequence([scaleIn, fadeOut, delete])

        explosionFirst.run(animation)
        explosionFirst.run(explosionSequence)
    }
}

编译器看到self.GameScene.addChild并且你没有引用你的GameScene对象所以创建一个

var gameScene : GameScene!

现在使用：

gameScene.addChild(explosionFirst)

注意：默认情况下，您的初始化工具现在为gameScene: GameScene，因此您必须在Gamescene

上注入init依赖关系

从另一个类向GameScene添加节点
