python - 如果我的玩家降落在某个街区，我如何杀死它

Question

所以我的问题是，当我降落在第 3 块或熔岩上时，我的玩家并没有死，我尝试了 if tile == '3': display.blit 和里面的东西，但在我放 pygame.退出并在下一行 sys.exit 它说

DeprecationWarning：需要一个整数（获取类型浮点数）。不推荐使用int隐式转换为整数，并且可能会在 Python 的未来版本中删除。obj_rect = pygame.Rect(background_object[1][0] - scroll[0] * background_object[0],

那么我的解决方案是什么，如果你需要我的地图，它就是。稍微解释一下。0 是空气，1 是泥土，2 是草，3 是熔岩。请全屏查看地图，否则它看起来会一团糟。

[ Grass.png 抱歉它很小，但我不在乎熔岩很大 ] 2 idle 位于播放器动画文件夹中的空闲集中，运行位于播放器动画文件夹中的运行集中。对不起，如果有小，但我希望熔岩很大，并且由于弃用警告代码没有运行并且刚刚结束。

警告只是意味着您将浮点数传递给Rect构造函数。Pygame 无法绘制半像素，因此它会在内部进行舍入，从而浪费 CPU 周期。

一个快速的解决方法是将参数转换为整数。用于int截断浮点数的小数部分。

obj_rect = pygame.Rect(int(background_object[1][0] - scroll[0] * background_object[0]),
                       int(background_object[1][1] - scroll[1] * background_object[0]), 
                       int(background_object[1][2]),
                       int(background_object[1][3]))
