Swift 3 测试 SKNode 的 SKSpriteNode 子类是否包含触摸

Question

class MainNode:SKNode {
    class Box: SKSpriteNode {
        override init(texture: SKTexture?, color: UIColor, size: CGSize) {
            super.init(texture: SKTexture(imageNamed: "testIMG1"), color: UIColor.clear, size: CGSize(width: 50, height: 50))
        }
        required init?(coder aDecoder: NSCoder) {
            fatalError("init(coder:) has not been implemented")
        }
    }
    var subclassNode: SKSpriteNode!
    var box = Box()
    convenience init(size: CGSize) {
        self.init()
        box = Box()
        box.position.x = 0
        subclassNode = SKSpriteNode(color: UIColor.red, size: CGSize(width: 40, height: 40))
        subclassNode.position.x =  0
        subclassNode.zPosition = 6
        self.addChild(subclassNode)
    }
}

在我的课堂上MainNode我试图测试SKSpriteNode子类Box是否包含我的游戏场景中的触摸

添加

for touch in touches {
    let location = touch.location(in: self)
    if MainNode.SubclassNode.contains(location) {
        print("Subclass contains touch")
    }
}

到我的 GameScene 类或我的 MainNode 类似乎根本不起作用

，即使SubclassNode.isUserInteractionEnabled = true

如何确定触摸是否在我的子类中？

Answer 1

我在KnightOfDragon的更多研究和帮助下弄清楚

了

我设置了self.isUserInteractionEnabled = true，然后给我的子类节点起了一个名字subclassNode.name = "SubclassNode"然后将这段代码添加到我的MainNode类中

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in touches {
        let location = touch.location(in: self)
        let touchedNode = self.atPoint(location)
        if let name = touchedNode.name
        {
            if name == "SubclassNode" {
                print("touched Subclass Node")
            }
        }
    }
}
