呈现瓷砖中的显示错误- PyGame
提问于 2014-05-10 01:49:18
我担心这个问题过于本土化，但我希望你仍能对这种情况提出一些建议。
我将直截了当地说，一个“草”不断地显示在左上角，偶尔的“立方体”瓷砖也在那里闪烁。我找不到我的代码在哪里做这件事，这真的令我困惑。请看下面的代码，并发布您的想法，为什么我的代码会这样做。我已附上一段录像，以作进一步澄清。
编辑：删除不相关的代码。

你有两个问题：
- 您正在
Sprite.update()中绘图，然后调用tile_set.draw(screen)，因此您要绘制两次每个瓷砖。 - 您没有为您的瓷砖设置
rect属性，所以当您调用draw时，每个瓷砖都会根据它的rect属性在0,0位置绘制。
要解决这个问题，请实现如下所示的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))- 消除
update方法(如果将来需要它，不要使用它)。 - 在
get_rect方法中设置坐标。
