弹跳小球 V1.0

今天休息，用VS2005写了个简单小游戏，贴出代码，与大家分享一下，一步步都做了什么。

第一步：画出框架，22*22的框子，一个球，一个档板1*4


第二步：档板的左右移动 档板的方向变量


第三步：让球自己向左上 左下 右上 右下四个方向移动


第四步：让球碰到墙后，反弹


第五步：让球碰到档板后，反弹


第六步：如何计算失败 到最底部


第七步：档板的移动速度与小球的移动速度分开 (这里原来是用单进程的，发现不好处理，档板移动快了，小球也跟着移动快，原来是想着，让小球以某一个固定的速度移动，想来想去，用了两个进程，进程1处理档板。进程2处理小球)


第八步：得分计算 增加难度 速度加快

现贴出图来，有图有真相啊！！(让我想起一句广告，“就放在这里晒，晒足180天”)

代码：
