重播按钮不起作用。 （Swift，SpriteKit）

Question

一旦我的游戏结束，它会显示一个重播按钮，但我无法理解如何在游戏结束后让Xcode知道是否有触摸。我的重播按钮的代码在didBeginContact方法中，如下所示：

func didBeginContact(contact: SKPhysicsContact) {
       if (.....) {
            ..........
      }  else {
         replayButton = SKSpriteNode(imageNamed: "ReplayButton")
            replayButton.position = CGPoint(x: size.width / 1.75, y: size.height / 2.5)
            replayButton.name = "replayButton"
            self.addChild(replayButton)
       }

New Swift文件：

class button: SKSprideNode {

let replayButton = button(imageNamed: "replayButton")


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

var touch = touches as!  Set<UITouch>
var location = touch.first!.locationInNode(self)
var node = self.nodeAtPoint(location)


if (node.name == "replayButton") {

    let myScene = EMode(size: self.size)
    let reveal = SKTransition.fadeWithDuration(2.0)
    self.scene!.view(myScene, transition: reveal)  //error on this line
    }
  }
}

Answer 1

您需要将重播按钮的用户互动设置为true，如下所示：

replayButton.userInteractionEnabled = true

然后你只需要听一下触摸按钮或场景的时间。一种方法是将SKSpriteNode的子类称为Button或其他内容，并覆盖touchesBegan方法。

实施例

<强> ButtonClass

class ExampleButton: SKSpriteNode {
    override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        //do stuff here
    }
}

按钮初始化

let button = ExampleButton(imageNamed: "ButtonImage")
button.userInteractionEnabled = true
