我试图检测我的精灵节点是否被触动，我不知道从哪里开始。
let Pineapple = SKSpriteNode(imageNamed: "Pineappleimg") Pineapple.userInteractionEnabled = true Pineapple.position = CGPoint(x: CGRectGetMidX(self.frame) - 200,y: CGRectGetMidY(self.frame)); self.addChild(Pineapple)
首先将SKSpriteNode的name属性设置为字符串。
pineapple.name = "pineapple" pineapple.userInteractionEnabled = false
然后在场景中的touchesBegan功能
override func touchesBegan(touches: NSSet,withEvent event: UIEvent) {
let touch:UITouch = touches.anyObject()! as UITouch
let positionInScene = touch.locationInNode(self)
let touchedNode = self.nodeAtPoint(positionInScene)
if let name = touchedNode.name
{
if name == "pineapple"
{
print("Touched")
}
}
}
这是一种方法。
您也可以将SKSpriteNode子类化并覆盖其中的touchesBegan。
class TouchableSpriteNode : SKSpriteNode
{
override func touchesBegan(touches: NSSet,withEvent event: UIEvent) {
print("touched")
}
}
然后做
let pineapple = TouchableSpriteNode(imageNamed: "Pineappleimg") pineapple.userInteractionEnabled = true pineapple.position = CGPoint(x: CGRectGetMidX(self.frame) - 200,y: CGRectGetMidY(self.frame)); self.addChild(pineapple)
