我正在使用升级系统在Pygame中制作游戏。每轮结束后，玩家将进入升级屏幕，点击他们想要使用他们收集的积分升级的统计数据。但是，如果玩家有足够的积分进行第一次升级并点击ATK升级，它将升级攻击然后再次检查循环。因此，如果玩家也有足够的积分进行第二次升级，我的程序第二次运行升级而玩家没有点击按钮两次。
如果只注册一次点击，我该怎么做才能让我的程序在一次点击中不会花费每一点？
更新：我发现，如果我真的很快点击升级按钮，那么它会注册为一次点击，但如果它被保持不超过一秒钟，它会重复“点击”。当按下鼠标按钮然后释放时，有没有人知道如何只输入一次？
按钮类逻辑：
if x + width > mouse_pos[0] > x and y + height > mouse_pos[1] > y:
text_to_button(message, color, x, y, width, height)
if event.type == pygame.MOUSEBUTTONDOWN and pygame.mouse.get_pressed() == (1, 0, 0) and action != None:
实际按钮：
button("ATK", RED, D_RED, 110, 280, 145, 50, action = "ATK")
ATK升级逻辑：
if action == "ATK":
if player.attack == 1 and up_points >= 3:
player.attack += .5
up_points -= 3
elif player.attack == 1.5 and up_points >= 6:
player.attack += .5

答案 0 :(得分：0)
您没有显示完整的代码，但我猜您的问题是在pygame.mouse.get_pressed()某处使用MOUSEBUTTONDOWN事件。
每次鼠标点击都会生成一个MOUSEBUTTONDOWN个事件;但是如果你在循环中检查pygame.mouse.get_pressed()，你会看到该循环的多次迭代按下按钮（如果你的速度不够快，不能释放鼠标按钮）。
请注意，MOUSEBUTTONDOWN事件具有button属性，可用于检查按下了哪个按钮。
