我在暂停和取消暂停场景时遇到两个问题。我有按钮:
playPause = SKSpriteNode(imageNamed: "buttPause.png")
playPause.name = "pause"
playPause.setScale (0.65)
playPause.position = CGPoint(x: -self.frame.width / 2.55 , y: self.frame.height / 2.27)
playPause.zPosition = 10
self.addChild(playPause)
我已经设置了暂停和取消暂停场景+更改按钮纹理的功能:
func buttonpauseplayTouched() {
if isPlaying {
playPause.texture = SKTexture(imageNamed: "buttPlay")
isPlaying = false
self.scene?.view?.isPaused = true
}
else {
playPause.texture = SKTexture(imageNamed: "buttPause")
isPlaying = true
self.scene?.view?.isPaused = false
}
}
我已经设置了触摸按钮:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
location = touch.location(in: self)
node = self.atPoint(location)
if node.name == "pause" {
buttonpauseplayTouched()
}
else {print ("Blank space")}
}
}
现在,当我触摸暂停按钮时,我可以暂停和取消暂停场景,但纹理不会改变?怎么了?或者,如果我想在暂停时将其他 spritekit 节点添加到场景中,我不能。
第二个问题是,我在场景中还有一些其他 SKSpriteNode,并且当我触摸它们时我已经设置了操作。如果我在场景暂停时触摸它们,则不会发生任何事情,但是当我取消暂停场景时,对象上的操作就会运行。如何防止场景暂停时无法对对象执行操作。我尝试:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
location = touch.location(in: self)
node = self.atPoint(location)
if node.name == "pause" {
buttonpauseplayTouched()
}
else if scene?.view?.isPaused == true && node.name == "object" {print ("Nothing!!")}
}
else {print ("Blank space")}
}
}
没有成功。感谢您的任何提示。
UPDATE:
再次感谢两位!
带图层的解决方案更好,我尝试了一下,效果很好!一个小问题是移动背景:
override func didMove(to view: SKView) {
createBackground()
}
func createBackground(){
for i in 0...3 {
background = SKSpriteNode(imageNamed: "background1.png")
background.name = "background"
background.setScale(0.694)
background.position = CGPoint(x: 0, y: CGFloat(i) * background.size.height)
background.zPosition = 1
gameLayer.addChild(background)
}
}
func moveBackground(){
gameLayer.enumerateChildNodes(withName: "background", using: ({
(node, error) in
node.position.y -= 7
if node.position.y < -((self.background.size.height)) {
node.position.y += (self.background.size.height) * 3
}
}))
}
override func update(_ currentTime: TimeInterval) {
moveBackground()
}
当我暂停游戏层时,背景仍在移动。如何编辑代码以在游戏层暂停时停止移动背景?我希望只需要稍微改变一下代码就可以解决这个问题。谢谢!
