安卓游戏 收集钱袋（自制）

本人对游戏这一块很有兴趣，刚好 又兼着学安卓，所以就学着做了下安卓的 游戏

本文章是自己学习和记录用，喜欢的人可以阅读，写的不好的勿喷

开始，安卓基本的东西和环境的搭建就不细说了，先进行游戏的基本分析：

需要的元素：钱 钱袋 画板

小游戏，仅仅是机能的一些测试，所以没有做的很好，

个人喜欢做游戏的原因就是因为游戏和现实的世界非常的贴近，能够用现实的想法去思考游戏

比如本游戏：首先，钱肯定是默认的情况下就不停的运动的，然后钱袋，由玩家去控制，也能进行移动，当钱和钱袋接触，进行加分，并且钱消失，就是这么一段简单的想法

　钱这个类

　　这里加入了一个摇杆系统，没特别作用，好看罢了

基本代码已经给出，也没什么素材，代码本人亲测成功的，后期有打算完善的可能性，当然还是得需要一个美工得协助
