AS代码如下：
//这个函数是用来绘制线条的
function connect(){
this.clear()
this.lineStyle(3,0x660000,100)
this.moveTo(anchorOne._x,anchorOne._y)
this.curveTo(controlOne._x,controlOne._y,anchorTwo._x,anchorTwo._y)
updateAfterEvent()
}
//这个函数是用来绘制替代描点跟控制点的MC，就绘制一个正方形吧
function createSquare(handle,side,offset){
if(offset==undefines){
offset=0
}
with(handle){
moveTo(offset,offset)
lineTo(offset,side)
lineTo(side,side)
lineTo(side,offset)
lineTo(offset,offset)
endFill()
}
}
//这是用来控制描点跟控制点的移动，并且用延时，间隔一段时间调用一次绘制线条
function setDraggable(handle){
handle.onPress=function(){
clearInterval(_global.refreshScreen)
_global.refreshScreen=setInterval(this._parent,"connect",10)
this.startDrag(false)
}
handle.onRelease=function(){
clearInterval(_global.refreshScreen)
this.stopDrag()
}
handle.onReleaseOutside=function(){
clearInterval(_global.refreshScreen)
this.stopDrag()
}
}
//建立描点
anchorOne=createEmptyMovieClip("anchorPoint1",this.getNextHighestDepth())
