ios - 带子节点的SKSpriteNode的触摸检测

Question

我正在尝试在点击其子节点的 SKSpriteNode 上触发触摸事件。当它接触到子节点时，不会触发该事件。我发现了一种使用 .parent 的 hack 方法，但我觉得这不是最有效或最优雅的方法。

请看下面的代码:

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...
    }
}

非常感谢帮助。

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
    }
}
