我必须为上课做一场游戏，必须有滚动照相机，完全纹理的背景，并且要使子画面流畅。我需要将矩形变成精灵。我在Add scrolling to a platformer in pygame上找到了此代码，但是我试图弄清楚如何删除矩形并导入精灵。也许在关卡上添加一些纹理。有人可以帮我弄这个吗？谢谢：）

图像必须b加载到pygame.Surface
而不是创建一个Surface并用一种颜色填充它（如您所愿）
pygame.Surface
您必须通过加载图像来创建表面（请参见self.image = Surface((TILE_SIZE, TILE_SIZE))
self.image.fill(color)
）
pygame.image.load[pygame.image.load是图像文件的完整路径和文件名。
