我想在我的射击游戏中添加一个弹药夹子的东西，它非常简单我所做的就是blit我*弹药的数量，但我希望有三条线来显示这样的剪辑：
IIIIIIIIIIIIIIIIIIIIII
IIIIIIIIIIIIIIIIIIIIII
IIIIIIIIIIIIIIIIIIIIII
每一行都有35个弹药符号，但如果玩家的弹药数量超过95，我希望它能弹出那个弹药夹旁边的数字，但无论我有多少弹药，它都不会闪现数字，无论如何我开始时有多少弹药，它在开始时不会比这更多，直到我收集一个弹药箱：
IIIIIIIIII
我真的无法找出它为什么会这样做，我试图改变它的数量以及许多其他东西，但似乎没有任何效果，所以听到我的代码：
#wave font
font = pygame.font.SysFont("", 34)
self.text_pause = font.render("WAVE " + str(self.wave) * self.blitwave, -1, RED)
self.text_pause_rect = self.text_pause.get_rect(center=self.screen.get_rect().center) # center text
texthealth = int(self.health / 10)
#health font
self.text_health = font.render("o" * texthealth, -1, RED)
#score font
self.text_score = font.render("SCORE " + str(self.score), -1, BLACK)
#cash font
self.text_cash = font.render(str(self.cash), -1, GREEN)
#ammo font
self.text_ammoS = font.render("I" * 35, -1, RED)
self.text_ammo = font.render("I" * self.ammo_amount, -1, RED)
self.text_ammoW = font.render("I" * (self.ammo_amount - 35), -1, RED)
self.text_ammoE = font.render("I" * (self.ammo_amount - 70), -1, RED)
self.text_ammoN = font.render(str(self.ammo_amount), -1, RED)

我以为我可以制作一个跟随块的矩形，如果那个矩形与他的玩家发生碰撞他们死了，几乎使用与弹药相同的系统，因为它立即起作用

非常感谢您的时间和帮助。
答案 0 :(得分：1)
你没有弹出弹药号码 - 请参阅#排队：
#self.screen.blit(self.text_ammo, (450, 610))
必须是text_ammoN而不是text_ammo
顺便说一下：
你需要在主循环中使用很多代码 - 将一些代码放在诸如update_wave_text（），update_ammo_text（）等函数中，blit_wave_text（），blit_ammo_tex（）等等。
在self.设置
__init__ :.
self.screen_width = 850
self.screen_height = 640
而不是使用self.screen_width，self.screen_height，您将不必重复
screen_width = 850
screen_height = 640
