[英]How can I pause a game in SpriteKit and SceneKit - SWIFT
I'm trying to pause my game by touching a button but I can't get it to work. 我试图通过触摸按钮来暂停游戏,但无法正常工作。
I tried this : 我尝试了这个:
pause = SKSpriteNode (imageNamed: "pause.png")
pause.size = CGSizeMake(30, 30)
pause.position = CGPointMake(30, 30)
self.addChild(pause)
and I'm trying to call a function like this: 我正在尝试调用这样的函数:
func touchesBegin (touches: NSSet!, withEvent event: UIEvent!)
{
for touch: AnyObject in touches
{
let location = touch.locationInNode(self)
if self.nodeAtPoint(location) == self.pause
{
let skView = self.view as SKView
skView.paused = true
}
}
}
When I touch the pause button nothing happens... what's wrong? 当我触摸暂停按钮时,什么都没有发生……怎么了?
Thank you! 谢谢!
I resolved by myself the problem : 我自己解决了这个问题:
here my code function : 这是我的代码功能:
override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!)
{
var touch:UITouch = touches.anyObject() as UITouch
pauseText.text = "Pause"
pauseText.fontSize = 50
pauseText.position = CGPointMake(self.frame.size.width/2, self.frame.size.height/2)
/* bouton play/pause */
var locationPause: CGPoint = touch.locationInNode(self)
if self.nodeAtPoint(locationPause) == self.pause
{
addChild(pauseText) // add the text
pause.removeFromParent () // to avoid error when you touch again
self.runAction (SKAction.runBlock(self.pauseGame))
}
}
To resume the game you just have to add this code before the last "}" : 要继续游戏,您只需在最后一个“}”之前添加以下代码:
if self.nodeAtPoint(locationPause) == self.pauseText
{
pauseText.removeFromParent() // remove the pause text
self.view.paused = false // resume the game
addChild(pause) // add the pause button
}
And in SKScene subclass add this function to add a label during the pause : 并在SKScene子类中添加此函数以在暂停期间添加标签:
func pauseGame()
{
self.view.paused = true // to pause the game
}
