Question

当两个精灵节点发生碰撞时，我想为我的游戏制作动画。所以我创建了这个函数：

func contactEntreMeteorites(Meteorites : SKSpriteNode , Meteorites2 : SKSpriteNode){

        Meteorites.removeFromParent()
        Meteorites2.removeFromParent()

        let ExplosionTexture1 = SKTexture(imageNamed: "Explosion1.png")
        let ExplosionTexture2 = SKTexture(imageNamed: "Explosion2.png")
        let ExplosionTexture3 = SKTexture(imageNamed: "Explosion3.png")
        let ExplosionTexture4 = SKTexture(imageNamed: "Explosion4.png")
        let ExplosionTexture5 = SKTexture(imageNamed: "Explosion5.png")
        let ExplosionTexture6 = SKTexture(imageNamed: "Explosion6.png")
        let ExplosionTexture7 = SKTexture(imageNamed: "Explosion7.png")
        let ExplosionTexture8 = SKTexture(imageNamed: "Explosion8.png")
        let ExplosionTexture9 = SKTexture(imageNamed: "Explosion9.png")
        let ExplosionTexture10 = SKTexture(imageNamed: "Explosion10.png")
        let ExplosionTexture11 = SKTexture(imageNamed: "Explosion11.png")
        let ExplosionTexture12 = SKTexture(imageNamed: "Explosion12.png")

        let animateExplosion = SKAction.sequence([
            SKAction.waitForDuration(0, withRange: 0),
            SKAction.animateWithTextures([ExplosionTexture1,ExplosionTexture2,ExplosionTexture3,ExplosionTexture4,ExplosionTexture5,ExplosionTexture6,ExplosionTexture7,ExplosionTexture8,ExplosionTexture9,ExplosionTexture10,ExplosionTexture11,ExplosionTexture12 ], timePerFrame: 0.1)
            ])

        Explosion = SKSpriteNode(texture: ExplosionTexture1)
        Explosion.position = CGPointMake(Meteorites.position.x, Meteorites.position.y)
        Explosion.runAction(animateExplosion)
        self.addChild(Explosion)

    }

此代码完美无缺，但我不知道如何在SpriteNode animateExplosion完成时删除SKAction sequence“Explosion”。

感谢您的帮助:)对不起我的英语我是法国人;）

Answer 1

您实施了错误的方法。而不是runAction:，实施runAction:completion:。 completion方法在完成时将被称为！这是删除爆炸节点的地方。

Answer 2

所以这就是解决方案：

Explosion = SKSpriteNode(texture: ExplosionTexture1)
        Explosion.position = CGPointMake(Meteorites.position.x, Meteorites.position.y)
        self.addChild(Explosion)
        Explosion.runAction(animateExplosion, completion : {self.Explosion.removeFromParent()})

制作爆炸动画SKaction并删除
