pygame多键射击冷却

问题描述

在我的游戏中，玩家可以使用WASD键发射不同颜色的子弹。播放器可以立即发射子弹，就像他们现在按下键一样快，这意味着您可以将WASD键混在一起并发射子弹流。我曾尝试创建一个USEREVENT来冷却玩家可以射击的时间，但是我不确定自己是否做对了，因为我在玩游戏时根本不射击。

#cooldown userevent
shot_cool = pygame.USEREVENT + 2
pygame.time.set_timer(shot_cool,10)

running = True 
while running:
  clock.tick(FPS) 
    
    for event in pygame.event.get(): 
        
        if event.type == pygame.QUIT: 
            running = False #breaks out of the while loop
        if event.type == pygame.KEYDOWN and event.type == shot_cool: 
            if event.key == pygame.K_w: 
                pygame.time.set_timer(shot_cool,10)
                player.shoot('red')   
          
            elif event.key == pygame.K_a: 
                pygame.time.set_timer(shot_cool,10)
                player.shoot('green')

            elif event.key == pygame.K_s: 
                pygame.time.set_timer(shot_cool,10)
                player.shoot('white')

            elif event.key == pygame.K_d: 
                pygame.time.set_timer(shot_cool,10)
                player.shoot('blue')

有什么办法可以使玩家有短暂的冷却时间，直到他可以发射另一枚子弹？

解决方法

正如我在评论中所说，您完美地解决了您的问题。但是由于我已经在编辑器中拥有它，所以我决定再分享一点。由于所有按键的功能相同，因此您可以使用字典在同一功能块中对其进行处理。最终可能看起来像这样：

#cooldown userevent
EVT_SHOT_COOLDOWN = pygame.USEREVENT + 2

# shot cool down time
COOLDOWN_TIME_MS = 100

SHOT_KEYS = {
    pygame.K_w:'red',pygame.K_a:'green',pygame.K_s:'white',pygame.K_d:'blue',}

running = True 
shot_delay = False
while running:
    clock.tick(FPS) 
    for event in pygame.event.get(): 

        if event.type == pygame.QUIT: 
            running = False #breaks out of the while loop

        elif event_type == shot_cool:
            shot_delay = False
        
        elif event.type == pygame.KEYDOWN: 
            
            # handle shooting keys
            if (event.key in SHOT_KEYS and not shot_delay):
                pygame.time.set_timer(shot_cool,COOLDOWN_TIME_MS)
                shot_delay = True
                player.shoot(SHOT_KEYS[event.key])
            
            # handle other keys (if any)

感谢RufusVS的评论，您说的很完美。这是工作代码：

shoot_cooldown = pygame.USEREVENT +2
pygame.time.set_timer(shoot_cooldown,100)
shot_delay = False

running = True
while running:
     for event in pygame.event.get(): 
        
        if event.type == pygame.QUIT: 
            running = False 
        if event.type == shoot_cooldown:
            shot_delay = False
        if event.type == pygame.KEYDOWN: 
            if event.key == pygame.K_w and shot_delay == False: 
                pygame.time.set_timer(shoot_cooldown,100)
                shot_delay = True
                player.shoot('red')             
            elif event.key == pygame.K_a and shot_delay == False: 
                pygame.time.set_timer(shoot_cooldown,100)
                shot_delay = True
                player.shoot('green')
            elif event.key == pygame.K_s and shot_delay == False: 
                pygame.time.set_timer(shoot_cooldown,100)
                shot_delay = True
                player.shoot('white')
            elif event.key == pygame.K_d and shot_delay == False: 
                pygame.time.set_timer(shoot_cooldown,100)
                shot_delay = True
                player.shoot('blue')
