Question

当我将精灵移动到屏幕右侧时，我不断收到分段错误或崩溃。

我试图让我的＆＃34;精灵＆＃34;到＆＃34;切换＆＃34;我在与面具接触点处有另一个图像的像素，然后在它离开时改回来。目前它做得不太好，分段错误也没有帮助。

此项目的基础是https://www.youtube.com/watch?v=Idu8XfwKUao上 code.Pylet 所示的基础。在我修改它的地方就是我遇到问题的地方，从while循环开始。根据我的IDE，它与 maskOverlap 变量的设置有关，我认为错误更具体地说是 offset2 变量

所以我的问题是：任何人都可以看到分段错误发生的地点和原因，以及：我可以做些什么来改善我的精灵的结果，然后改变颜色，然后再回来。
