影片片段Code

>> 要讓走路走10次之後回到原本靜止的狀態。
影格1    stop()，並宣告i。

stop()
var i:int=0;

影格10  按F7，之後F9，輸入i=i+1;

i=i+1;

影格24  按F7，之後F9，寫if判斷式，i<=10跳至影格10繼續播，否則跳至影格1並停止。

if(i<=10)
{
this.gotoAndPlay("_walk")
}else{
this.gotoAndStop("_stand")
}

影格32

i=i+1;

影格42

if(i<=10)
{
this.gotoAndPlay("_jump")
}

控制Code

滑鼠滑過、按下可以跑跳

pig.addEventListener(MouseEvent.MOUSE_OVER, pigover);
pig.addEventListener(MouseEvent.CLICK, pigjump);
function pigover(e:MouseEvent):void
{
this.pig.gotoAndPlay("_walk")
}
function pigjump(e:MouseEvent):void
{
this.pig.gotoAndPlay("_jump")
}

避免重跳、互相干擾 _ 方法1

pig.addEventListener(MouseEvent.MOUSE_OVER, pigover);
pig.addEventListener(MouseEvent.CLICK, pigjump);
function pigover(e:MouseEvent):void
{
if (Object(this).pig.currentFrame == 1) {
Object(this).pig.i = 0;
this.pig.gotoAndPlay("_walk");
}
}
function pigjump(e:MouseEvent):void
{
if (Object(this).pig.currentFrame < 25) {
Object(this).pig.i = 0;
this.pig.gotoAndPlay("_jump");
}
}

 避免重跳、互相干擾 _ 方法2

取消登記，將addevent在function中remove。
EX.
this.removeEventListener(MouseEvent.MOUSE_OVER, thisover);

為了提供大量複製功用，將程式複製至影片片段的影格1。

最後完整的Code

stop();
var i:int = 0;


this.addEventListener(MouseEvent.MOUSE_OVER, thisover);
this.addEventListener(MouseEvent.CLICK, thisjump);

function thisover(e:MouseEvent):void
{
this.removeEventListener(MouseEvent.MOUSE_OVER, thisover);

this.i = 0;
this.gotoAndPlay("_walk");

}
function thisjump(e:MouseEvent):void
{
this.removeEventListener(MouseEvent.CLICK, thisjump);

this.i = 0;
this.gotoAndPlay("_jump");

}
