关于UITouch (雪碧套件)确实需要帮助

Question

我喜欢创造左侧和右侧，当我触摸它们时，一只鸟会向左或向右飞！

1. 我创造了一只鸟 鸟纹理= SKTexture(imageNamed："flappy1.png")鸟=SKSpriteNode(纹理:鸟纹理) bird.position bird.size bird.physicsBody = SKPhysicsBody(circleOfRadius: bird.size. false /2) bird.physicsBody?.dynamic = true bird.physicsBody?.allowsRotation =false self.addChild(鸟)
2. 然后创建左节点。 SKPhysicsBody(rectangleOfSize:CGSizeMake(self.size.width，groundleft.position = CGPoint(x: 0，y: 50) groundleft.size =CGSize(宽度: 500，高度: 100) groundleft.color =UIColor(红色: 7，绿色: 5，蓝色: 7，α: 20) groundleft.physicsBody =CGPoint 100) groundleft.physicsBody?.dynamic = true groundleft.physicsBody?.affectedByGravity = false groundleft.name = "toleft“self.addChild(左)
3. 然后我去了TouchBegan 让触摸= touches.first！bird.physicsBody?.applyImpulse(CGVectorMake(-10，UITouch touchLocation = touch.locationInNode(self)让touchedNode = self.nodeAtPoint(touchLocation) if(touchedNode.name == "toleft"){ bird.physicsBody?.velocity = CGVectorMake(0，0) touchedNode 100)}

为什么它不起作用。我的方法错了吗？我还有别的办法让它起作用吗?？请帮帮忙，非常感谢

在您的touchesBegan方法中，请尝试如下：

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

    if let touch = touches.first as? UITouch {

        let touchLocation = touch.locationInNode(self)
        if nodeAtPoint(touchLocation) == groundleft {   //your sprite node
            //do something

        } 
    }
    super.touchesBegan(touches , withEvent:event)
}
