本教程介绍如何使用Flash CS3的ActionScript (AS) 制作一个简单的鼠标跟随弹性小球游戏。主要步骤包括创建四个电影剪辑元件、编写AS代码实现小球跟随鼠标并具有弹性效果。

用Flash CS3的AS制作跟随鼠标弹性小游戏，主要是练习AS的使用。
先看演示：

首先建立4个小的电影剪辑元件，分别设置如下：

回到主场景中加入如下代码：
attachMovie("newmouse","newmouse",_root.getNextHighestDepth());
attachMovie("circle","circle",_root.getNextHighestDepth(),{_x:250, _y:200});
attachMovie("crosshair","crosshair",_root.getNextHighestDepth());
attachMovie("ball","ball",_root.getNextHighestDepth());
Mouse.hide();
friction = 0.9;
speed_scale = 0.1;
xspeed = 0;
yspeed = 0;
newmouse.onEnterFrame = function() {
    this._x = _root._xmouse;
    this._y = _root._ymouse;
};
crosshair.onEnterFrame = function() {
    this._x = _root._xmouse;
    this._y = _root._ymouse;
    dist_x = this._x-circle._x;
    dist_y = this._y-circle._y;
    distance = Math.sqrt(dist_x*dist_x+dist_y*dist_y);
    if (distance>45) {
        angle = Math.atan2(dist_y, dist_x);
        this._x = 250+45*Math.cos(angle);
        this._y = 200+45*Math.sin(angle);
    }

};
ball.onEnterFrame = function() {
    dist_x = (crosshair._x-this._x)*speed_scale;
    dist_y = (crosshair._y-this._y)*speed_scale;
    xspeed += dist_x;
    yspeed += dist_y;
    xspeed *= friction;
    yspeed *= friction;
    this._x += xspeed;
    this._y += yspeed;
};
按Ctrl+Enter测试影片吧！
