使用子节点

Question

我试图在SKSpriteNode上触发触摸事件，其中点击了其子节点。当它触摸的子节点时，事件不会被触发。我发现使用.parent进行黑客攻击，但并不觉得最有效或最优雅的做法是。

请参阅以下代码：

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    let touch = touches.first! as UITouch
    let location = touch.locationInNode(self)
    let node = self.nodeAtPoint(location)

    if node is PlanListItem || node.parent is PlanListItem {

        for plan in planListItems as [PlanListItem] {
            plan.selected = false
        }

        // Some more code...
    }
}

非常感谢。

您可以在节点子类中执行此操作：

class PlanListItem:SKSpriteNode {

    var isSelected: Bool = false
    override init(texture size etc) {
        //your init
        self.userInteractionEnabled = true
    }

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        print("PlanListItem touched")
        isSelected = !isSelected
    }
}
