这是我在这里的第一个问题 - Hello Word。
我的代码有一个小问题。我想强制执行这个程序,只有当你触摸并等于y:650点时才会出现球,并且只有当你在y:650点下触摸时才出现方框。 x位置在这里没有任何作用。
那是我的代码:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
if let touch = touches.first {
let location = touch.location(in: self)
let objects = nodes(at: location)
if objects.contains(editLabel) {
editingMode = !editingMode
} else {
if editingMode {
let size = CGSize(width: GKRandomDistribution(lowestValue: 16, highestValue: 128).nextInt(), height: 16)
let box = SKSpriteNode(color: RandomColor(), size: size)
box.zRotation = RandomCGFloat(min: 0, max: 3)
box.position = location
box.physicsBody = SKPhysicsBody(rectangleOf: box.size)
box.physicsBody!.isDynamic = false
addChild(box)
} else {
let ball = SKSpriteNode(imageNamed: "ballRed")
ball.physicsBody = SKPhysicsBody(circleOfRadius: ball.size.width / 2.0)
ball.physicsBody!.contactTestBitMask = ball.physicsBody!.collisionBitMask
ball.physicsBody!.restitution = 0.4
ball.position = location
ball.name = "ball"
addChild(ball)
}
}
}
}
期待寻求帮助:)
答案 0 :(得分:0)
对我来说这很有效:
ball.position = location
if (location.y < 500) {
ball.position.y = 500
}
