我在一个破解得的课件中发现有你说的功能，但不很全。
画线的代码为：onClipEvent(load){
this.createTextField("tip",0,0,-10,0,0);
with(tip){
autoSize="center";
type="dynamic";
textColor=16711680;
}
path=_parent._parent.paper;
this.onRelease=function(){
varRegister_1_=_parent;
Register_1_.handler4();
if(_currentframe==1){
Register_1_.handler();
gotoAndStop(2);
Register_1_._parent.mask._visible=true;
tip.text="èú";
}else{
gotoAndStop(1);
tip.text="ú";
}
tabEnabled=false;
};
this.onRollOver=function(){
if(_currentframe==1){
tip.text="ú";
}else{
tip.text="èú";
}
};
this.onRollOut=function(){
tip.text="";
};
this.onMouseDown=function(){
if(_currentframe==2&&path.write){
down=true;
n=path.n;
path.createEmptyMovieClip(("instance"+n),n);
with(path[("instance"+n)]){
lineStyle(3,path.RGB,100);
moveTo(path._xmouse,path._ymouse);
lineTo((path._xmouse+0.201),(path._ymouse+0.201));
}
}
};
this.onMouseMove=function(){
if(down&&path.write){
with(path[("instance"+n)]){
lineTo(path._xmouse,path._ymouse);
}
}
};
this.onMouseUp=function(){
if(down){
down=false;
n++;
path.n=path.m=n;
}
};
}
清除的代码为：
on(release){
n=0;
while(n<path.n){
path[("instance"+n)].removeMovieClip();
path[("instance"+n)].removeTextField();
n++;
}
path.n=path.m=0;
handler1();
}
我不知道得很详细，但能实现你说的功能，不知你是否满意？？
