[英]How can I stop the timer?
I just started to learn how to program games for Apple and i've been searching how to stop a timer. 我刚开始学习如何为Apple编写游戏程序,并且一直在寻找如何停止计时器的方法。 In the following code i have i want to stop the timer i made but I'm having trouble how to stop it. 在下面的代码中,我想停止计时器,但是我很难停止它。 i have no clue. 我没有任何线索。 Please help me! 请帮我! Thank you! 谢谢!
class Game: SKScene { 类游戏:SKScene {
var Ball = SKSpriteNode(imageNamed: "Red.png")
var QuitOption = SKLabelNode()
var ScoreLabel = SKLabelNode()
var timescore = Int()
var timesecond = Int()
var locked = false
override func didMoveToView(view: SKView) {
backgroundColor = SKColor.blackColor() // background for the display
self.physicsWorld.gravity = CGVectorMake(0, -9.8)
let SceneBody = SKPhysicsBody(edgeLoopFromRect: self.frame)
SceneBody.friction = 0
self.physicsBody = SceneBody
Ball.size = CGSize(width: 120, height: 120)
Ball.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.7)
Ball.physicsBody = SKPhysicsBody(circleOfRadius: 60)
Ball.physicsBody?.affectedByGravity = true
Ball.physicsBody?.restitution = 0.1
Ball.physicsBody?.linearDamping = 0
Ball.name = "Ball"
self.addChild(Ball)
QuitOption.text = "Quit"
QuitOption.fontName = "Noteworthy-Light"
QuitOption.fontColor = SKColor.greenColor()
QuitOption.fontSize = 35
QuitOption.position = CGPoint(x: self.frame.size.width/2 - 160, y: self.frame.size.height*1 - 110)
QuitOption.name = "Quit"
addChild(QuitOption)
ScoreLabel = SKLabelNode(fontNamed: "Noteworthy-Light")
ScoreLabel.fontSize = 50 // The + will move it to the right side and - to the left side for more accuracy.
ScoreLabel.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/4 + 400) // position of ScoreLabelNode
ScoreLabel.name = "Score+"
ScoreLabel.hidden = false
self.addChild(ScoreLabel)
}
// Making the ball jump after user touches ball
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
var touch = touches.first as! UITouch
var location = touch.previousLocationInNode(self)
// var location = touch.locationInNode(self)
var node = self.nodeAtPoint(location)
if (node.name == "Quit"){
let myScene = GameScene(size: self.size)
myScene.scaleMode = scaleMode
let reveal = SKTransition.fadeWithDuration(1)
self.view?.presentScene(myScene, transition: reveal)
}
if (node.name == "Ball"){
for touch: AnyObject in touches {
let location = touch.locationInNode(Ball)
Ball.physicsBody?.allowsRotation = true
Ball.physicsBody?.velocity = CGVectorMake(0, 0)
Ball.physicsBody?.applyImpulse(CGVectorMake(0, 100))

}
if(!self.locked){
self.locked = true
var actionrun = SKAction.waitForDuration(0.5)
var actionwait = SKAction.runBlock({
var stopTimer = false
self.timescore++
self.timesecond++
if self.timesecond == 60 {self.timesecond = 0}
self.ScoreLabel.text = " \(self.timescore/60):\(self.timesecond)"})
ScoreLabel.runAction(SKAction.repeatActionForever(SKAction.sequence([actionrun,actionwait])))
}
}
} }
Not a 100% sure what if I understand your question. 不能100%确定我是否理解您的问题。 But if "timer" is referring to your looping action, you could do this: 但是,如果“定时器”是指您的循环操作,则可以执行以下操作:
// This is just running your action with a name "scoreAction"
let loopAction = SKAction.repeatActionForever(
SKAction.sequence([actionrun,actionwait]))
ScoreLabel.runAction(loopAction, withKey: "scoreAction")
Later somewhere in you code you can stop this action by: 稍后在代码中的某个位置,您可以通过以下方式停止此操作:
ScoreLabel.removeActionForKey("scoreAction")
UPDATE: 更新:
If you only want to pause/un-pause animations you can use the paused
property on the objects you want to pause. 如果只想暂停/取消暂停动画,则可以对要暂停的对象使用paused
属性。
ScoreLabel.pause = true
It is good to know that the .pause
will affect the Node and any child nodes. 很高兴知道.pause
会影响Node和任何子节点。 You could pause the whole scene for instance: 例如,您可以暂停整个场景:
self.pause = true
Even the SKScene is a "node". 甚至SKScene都是一个“节点”。
