我担心这个问题过于局部化了，但我希望你仍然会对这种情况提出一些建议。
我会直截了当地说，左上角不断显示“草”，偶尔会出现“立方体”瓷砖闪烁。我无法找到我的代码在哪里这样做，这真的令我感到困惑。请查看以下代码，并发表您对我的代码为何会这样做的想法。我附上了一段视频，以便进一步澄清。
编辑：删除了不相关的代码。

答案 0 :(得分：1)
你有两个问题：
您正在使用Sprite.update()进行绘制，然后您正在调用tile_set.draw(screen)，因此每个图块都会绘制两次。
您没有为贴图设置rect属性，因此当您调用draw时，每个贴图都会根据其rect属性绘制在0,0位置
要解决此问题，请执行如下的Sprite子类：
class Grass(pygame.sprite.Sprite):
def __init__(self, tileX, tileY):
pygame.sprite.Sprite.__init__(self)
self.image = tile_dict[0]
self.rect = self.image.get_rect(topleft=(tileX,tileY))
update方法（如果将来需要它，请不要在其中绘制）。get_rect方法中设置坐标。
