在我的游戏中，玩家可以通过按空格键在屏幕的任何地方投掷炸弹。3秒后，炸弹的图像会被爆炸图像取代。我想让我的玩家与爆炸图像相撞时减少5个健康值。我尝试了几种方法，但是由于一些循环错误（我不明白），玩家在爆炸时不断失去健康。我想只减少5个健康值，即如果他的健康值是100，而他在爆炸时，应该只减少到95，而不是一直减少。我在下面附上我的完整代码。谢谢你的帮助。

当炸弹的阈值超过时，就会产生爆炸 在元组中添加一个额外的布尔属性，以指示plyer是否被炸弹伤害 ((pos2, end_time_2, False)):
for i in reversed(range(len(bombs))):
pos, end_time = bombs[i]
if current_time > end_time:
end_time_2 = end_time + 5000
pos2 = (pos[0] - 10, pos[1] - 30
explosions.append((pos2, end_time_2, False))
bombs.pop(i)
else:
screen.blit(pics[0], pos)
创建一个 pygame.Rect 炸弹和玩家，并评估弹头是否与炸弹相撞。改变 伤害 如果层叠器与爆炸相撞，则元组中的指示器。该 pygame.Rect 对象可以通过 pygame.Surface.get_rect. 位置可以通过一个关键字参数来设置（如 player_rect = player[0][0].get_rect(topleft = (x, y))):
for j in reversed(range(len(explosions))):
pos, end_time_2, hurt = explosions[j]
if current_time > end_time_2:
explosions.pop(j)
else:
screen.blit(pics[1], pos)
if not hurt:
explosion_rect = pics[1].get_rect(topleft = pos)
player_rect = player[0][0].get_rect(topleft = (x, y))
if player_rect.colliderect(explosion_rect):
explosions[j] = (pos, end_time_2, True)
