我怎样才能连续减少as3中的数字

Question

我打算做拔河比赛，并且我在这部分中遇到困难......游戏是用户必须快速点击按钮才能赢得比赛。我在数字使它1次点击= + 1，并在同一时间或不通过0.5

感谢一下控制器的值减小的帮助

var controller = 10; 
blocker.visible = false; 

function decreasing(){ 
controller = controller - 0.5; 
} 

decreasing(); 

pushBtn.addEventListener(MouseEvent.CLICK, theGame); 

function theGame (e:MouseEvent): void { 
controller = controller + 1; 

if ((controller <= 5) || (controller >=9)){ 
    ropeMc.gotoAndPlay("down1"); 
} 

if ((controller <= 1) || (controller >=4)){ 
    ropeMc.gotoAndPlay("down1"); 
} 

if ((controller >= 15) || (controller <=19)){ 
    ropeMc.gotoAndPlay("up1"); 
} 

if ((controller >= 20) || (controller <=29)){ 
    ropeMc.gotoAndPlay("up2"); 
} 

if (controller >= 30){ 
    ropeMc.gotoAndStop(20); 
    blocker.visible = true; 
} 

}

试试这个，

var controller = 10; 
    blocker.visible = false; 


stage.addEventListener(Event.ENTER_FRAME, decreasing); 
pushBtn.addEventListener(MouseEvent.CLICK, theGame); 

function theGame (e:MouseEvent): void { 
controller = controller + 1; 
changeState(); 

} 


function decreasing(e:Event){ 
controller = controller - 0.5; 
} 

function changeState():void{ 

if ((controller <= 5) || (controller >=9)){ 
    ropeMc.gotoAndPlay("down1"); 
} 

if ((controller <= 1) || (controller >=4)){ 
    ropeMc.gotoAndPlay("down1"); 
} 

if ((controller >= 15) || (controller <=19)){ 
    ropeMc.gotoAndPlay("up1"); 
} 

if ((controller >= 20) || (controller <=29)){ 
    ropeMc.gotoAndPlay("up2"); 
} 

if (controller >= 30){ 
    ropeMc.gotoAndStop(20); 
    blocker.visible = true; 
    stage.removeEventListener(Event.ENTER_FRAME, decreasing); 
} 
} 

希望它有帮助。
