我怎樣才能連續減少as3中的數字

Question

我打算做拔河比賽，並且我在這部分中遇到困難......遊戲是用戶必須快速點擊按鈕才能贏得比賽。我在數字使它1次點擊= + 1，並在同一時間或不通過0.5

感謝一下控制器的值減小的幫助

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; 
} 

}

試試這個，

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); 
} 
} 

希望它有幫助。
