我正在制作一個 pygame 游戲，一個人可以從商店購買炸彈。玩家也可以投下他購買的炸彈。我需要一種方法讓每個炸彈在投下 3 秒后消失。在下面的代碼中，我只能投下炸彈，但是我嘗試了各種方法但都失敗了。import pygameimport randompygame.font.init()width = 900height = 600screen = pygame.display.set_mode([width, height])walkRight = [pygame.image.load('R1.png'), pygame.image.load('R2.png'), pygame.image.load('R3.png'), pygame.image.load('R4.png'), pygame.image.load('R5.png'), pygame.image.load('R6.png'), pygame.image.load('R7.png'), pygame.image.load('R8.png'), pygame.image.load('R9.png')]walkLeft = [pygame.image.load('L1.png'), pygame.image.load('L2.png'), pygame.image.load('L3.png'), pygame.image.load('L4.png'), pygame.image.load('L5.png'), pygame.image.load('L6.png'), pygame.image.load('L7.png'), pygame.image.load('L8.png'), pygame.image.load('L9.png')]char = pygame.image.load('standing.png')bomb_pic = pygame.transform.scale(pygame.image.load('bomb.png'), (20,20))bomb_explosion = pygame.transform.scale(pygame.image.load('explosion1.png'), (40,40))# char_rect = char.get_rect()enemy_Left = [pygame.image.load('L1E.png'), pygame.image.load('L2E.png'), pygame.image.load('L3E.png'), pygame.image.load('L4E.png'), pygame.image.load('L5E.png'), pygame.image.load('L6E.png'), pygame.image.load('L7E.png'), pygame.image.load('L8E.png'), pygame.image.load('L9E.png')] x = 50y = 50width = 40height = 60vel = 5isJump = FalsejumpCount = 10left = Falseright = Falsedown = Falseup = FalsewalkCount = 0enemy_vel = 2enemy_list = []shop = pygame.transform.scale(pygame.image.load("shop.png"), (60, 60))clock = pygame.time.Clock()FPS = 60font = pygame.font.Font('freesansbold.ttf', 32)items_font = pygame.font.Font('freesansbold.ttf', 16)bombs =[]bag = {'bomb': 0}print(bag["bomb"])

用于pygame.time.get_ticks()獲取當前時間（以毫秒為單位）。計算炸彈必須消失的時間。將時間存儲到列表中bombs。該列表bombs必須包含位置和時間的元組。
如果時間已到，則從列表中刪除炸彈：
def redrawGameWindow():
current_time = pygame.time.get_ticks()
# [...]
for i in reversed(range(len(bombs))):
pos, end_time = bombs[i]
if current_time > end_time
bombs.pop(i)
else:
screen.blit(bomb_pic, pos)
def main():
# [...]
while run:
current_time = pygame.time.get_ticks()
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
# [...]
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE and bag["bomb"] >= 1:
pos = x + char.get_width()/2, y + char.get_height() - 20
end_time = current_time + 3000 # 3000 milliseconds = 3 seconds
bombs.append((pos, end_time))
bag["bomb"] -= 1
redrawGameWindow()
