无法更新矩形对象 pygame
Trouble updating rect object pygame
我是编码新手，玩游戏时遇到了问题。我希望白色矩形在单击时更改为新颜色。如果它们不是白色并且被点击它们不应该改变颜色。现在他们只是保持白色，所以我不确定他们是否没有更新或者我的鼠标点击检测是否错误。非常感谢任何帮助，谢谢！

您需要将颜色与白色进行比较，而不是与字符串 'white':
self.color == 'white'
self.color == pygame.Color('white')
collidepoint是pygame.Rect的一个方法。因此，您需要创建一个 pygame.Rect 对象：

# Updates rectangle to new colour if it is white and detects a mouse click
rect = pygame.Rect(self.center)
if self.color == pygame.Color('white') and rect.collidepoint(mouse_pos):
