我正在制作一个突破版本，虽然基础游戏正在运作，但我想制作等级。所以我想做的就是让它在球被击中x次之前不会被移除。
我试过添加一个计数器：
for brick in self.bricks:
if self.ball.colliderect(brick):
self.brick_counter += 1
self.score += 3
self.ball_vel[1] = -self.ball_vel[1]
if self.brick_counter == 2:
self.bricks.remove(brick)
break
但结果是球刚穿过砖块。
我还考虑过创建两层（或更多层）砖块，但我不确定如何实现它。
以下是完整的代码：

答案 0 :(得分：2)
看起来你正在使用pygame.Rect作为你的砖块对象和一个全局计数器来判断砖被击中的次数。一旦任何砖被击中两次，那么计数器就不再适当地达到其目的。你真正应该做的是创建一个同时具有矩形和计数器的Brick类，并更新砖块的计数器。
...
Application.CutCopyMode = False
dim nrw as long
nrw = activecell.row
with range(cells(nrw, "A"), cells(nrw, columns.count).end(xltoleft))
.cells(1, 1) = .cells(1, 1).value & "A"
.cells(1, .columns.count) = .cells(1, .columns.count).value & "A"
end with
然后self.bricks将是这些对象的列表。
此外，看起来你假设砖块会从底部或顶部碰撞并导致速度的y分量反转。如果它从侧面发生碰撞，弹跳看起来会有些奇怪，可能会导致球“刚刚穿过”的感觉。在发生碰撞时，您必须查看球相对于砖块的位置，并决定翻转速度的x分量或y分量。
这样的事情（抱歉，我可能不完全匹配您的字段，但您明白了）：
class Brick:
def __init__(self, rect):
self.rect = rect
self.hit_counter = 2
