先看效果：

点击这里下载源文件

制作非常简单，新建立文档，然后按Ctrl+J修改属性。

按Ctrl+R导入一幅图片，或者自己绘制一幅铅笔图。

按F8转变为元件。

为该元件设置实例名。

选择第一帧，添加如下Action。

this.attachMovie("cursor_id", "cursor_mc", this.getNextHighestDepth(), 

{_x:_xmouse, _y:_ymouse});

Mouse.hide();

var mouseListener:Object = new Object();

mouseListener.onMouseMove = function() {

pencil._x = _xmouse;

pencil._y = _ymouse;

updateAfterEvent();

};//建立一个铅笔图标

Mouse.addListener(mouseListener);//和铅笔图片联系在一起

this.createEmptyMovieClip("drawing_mc", this.getNextHighestDepth());

var mouseListener:Object = new Object();

mouseListener.onMouseDown = function() {

this.drawing = true;

drawing_mc.moveTo(_xmouse, _ymouse);

drawing_mc.lineStyle(3, 0x99CC00, 100);

};

mouseListener.onMouseUp = function() {

this.drawing = false;

};

mouseListener.onMouseMove = function() {

if (this.drawing) {

drawing_mc.lineTo(_xmouse, _ymouse);

}

updateAfterEvent();

};

Mouse.addListener(mouseListener);

var keyListener:Object = new Object();

keyListener.onKeyDown = function() {

if (Key.isDown(Key.DELETEKEY) || Key.isDown(Key.BACKSPACE)) {

drawing_mc.clear();

}

};

Key.addListener(keyListener);

按Ctrl+Enter测试吧！
