Detect touch on child node of object in SpriteKit
提问by Kyle Goslan
I have a custom class that is an SKNode, which in turn has several SKSpriteNodes in it. Is there a way I can detect touches on these child SKSpriteNodes from my game scene?
我有一个自定义类，它是一个 SKNode，其中又包含多个 SKSpriteNode。有没有办法可以从我的游戏场景中检测到这些子 SKSpriteNodes 上的触摸？

override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {
let touch = touches.anyObject() as UITouch
let touchLocation = touch.locationInNode(self)
if([yourSprite containsPoint: touchLocation])
{
//sprite contains touch
}
}

Examine Apple's SceneKitVehicledemo. Someone kindly ported it to Swift.
检查 Apple 的SceneKitVehicle演示。有人好心地将它移植到 Swift。
The code you want is in the GameView.swift file. In the GameView you'll see the touchesBegan override. Here's my version of it for Swift 2.1:
您需要的代码在 GameView.swift 文件中。在 GameView 中，您将看到 touchesBegan 覆盖。这是我的 Swift 2.1 版本：
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
guard let scene = self.overlaySKScene else {
return
}
let touch = touches.first!
let viewTouchLocation = touch.locationInView(self)
let sceneTouchPoint = scene .convertPointFromView(viewTouchLocation)
let touchedNode = scene.nodeAtPoint(sceneTouchPoint)
if (touchedNode.name == "Play") {
print("play")
}
}
If it's not clear; the GameView is set as the app's view class by way of the Storyboard.
如果不清楚；GameView 通过 Storyboard 设置为应用程序的视图类。

You'll need to compare the location of your Touch to the location of your SKNode
您需要将 Touch 的位置与 SKNode 的位置进行比较
You can get the location of your touch at one of the following methods, using locationInNode():
您可以通过以下方法之一使用 locationInNode() 获取触摸的位置：
- touchesBegan()
- touchesMoved()
- touchesEnded()
- 触摸开始（）
- 触摸移动（）
- 触摸结束（）
