突破游戏擦除矩形pygame

Question

我正在使用pygame模块制作一个突破性游戏，我已经建立了大部分功能。然而，我很难让球与屏幕顶部的盖帽相撞。具体地说；碰撞"；方法。我写了一个for循环来遍历块列表，以检查块是否与球碰撞，如果碰撞了，那么它会从row_1列表中删除块的相应索引，理论上会将块从屏幕上擦除。但我得到一个AttributeError："pygame.Rect"对象没有属性"collidirect"。我很感激你的帮助。

Answer 1

这是一个拼写错误。方法的名称是colliderect，而不是collidirect:

if block.collidirect(self.ball.ball_rect):

if block.colliderect(self.ball.ball_rect):
