主要是利用Flash Actionscript一步一步学习Flash高射炮简单游戏的制作过程，最终效果只是一个简单的演示，如果你有兴趣可以继续深入学习！(教程最后页提供演示动画的源程序下载）

第一步：首先简单的制作一个鼠标动画，绘制一个鼠标的图，自己定。然后选择第一帧输入下面代码： http://www.it55.com/
Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
}; www.it55.com |
效果如下：

绘制坦克

把下面的命名实例名为tank。代码如下： IT资讯之家 www.it55.com
Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle += 180;
}
if (mousex>=0 && mousey<0) {
angle += 360;
}
this.cannon._rotation = angle*-1;
};

第三步：我这里设置转动的一定的角度。 IT资讯之家 www.it55.com
Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle += 180;
}
if (mousex>=0 && mousey<0) {
angle += 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
this.cannon._rotation = angle*-1;
};

然后是计算开火的目标：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle += 180;
}
if (mousex>=0 && mousey<0) {
angle += 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
firepower = Math.sqrt(mousex*mousex+mousey*mousey);
if (firepower>200) {
firepower = 200;
}
this.cannon._rotation = angle*-1; http://www.it55.com/
};
