如果它落在某个街区上，我该如何杀死我的玩家

编程问答 2022-06-10

问题描述

所以我的问题是，当我降落在第3块或熔岩上时，我的播放器没有死，并且我尝试了是否tile =='3'：display.blit及其内部的内容，但在我之后的行中将pygame.quit放到下一行sys.exit上

DeprecationWarning：必需为整数（got类型为float）。不建议使用 int 隐式转换为整数，并且在将来的Python版本中可能会将其删除。 obj_rect = pygame.Rect（background_object [1] [0]-滚动[0] * background_object [0]，

那我的解决方案是什么，如果您需要我的地图，那就是。 一点点解释。 0是空气，1是泥土，2是草，3是熔岩。请全屏查看地图，否则将看起来一团糟。

 idle位于播放器动画文件夹中的空闲设置中，运行位于播放器动画文件夹中的运行设置中。很抱歉，如果很小，但我希望熔岩变大，并且由于弃用警告，该代码未运行且仅结束。

解决方法

（评论要回答）

警告仅表示您正在将浮点数传递给Rect构造函数。 Pygame无法绘制半像素，因此它内部会四舍五入，浪费了CPU周期。

一个快速解决方案是将参数转换为整数。使用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]))
