Java实现微信跳一跳脚本

思路：

1.截取安卓模拟器对应窗口的图像内容

2.处理图像找出起点和终点

3.计算距离

4.鼠标事件

经过：

1.一开始想先将截图储存在某个路径，在用文件流读取那个图片，对图片进行处理。之后发现直接对BufferedImage里的内容进行处理更方便。

2.在计算距离的时候遇到了一点困难，用了取巧的办法。即找到新台阶中心点的横坐标，找到小人起跳点的横坐标，相减求得横向距离。手测三角形的长边和底边的比例，乘一下求出距离。

3.距离和按键时间的关系一开始以为是线性关系，后来发现好像并不是这样，想利用神经网络来拟合一下，还在思考实现方法。

结果：

1.能够自动地在安卓模拟器上刷到600+分，遇到圆形小台阶不是很稳，会掉下去。

2.在遇到圆形台阶时距离的测算会遇到一点问题，应该是三角形的形状变了，导致距离计算不准确，很难刷到高分。

待改进：

1.拟合距离-时间公式。

2.找到测距离更准确的办法。
