如何让pygame仅通过一次鼠标点击来识别？

问题描述

我有一个简单的游戏，我希望我的鼠标点击（按钮无关紧要）每次点击只注册一次。现在即使按住它也能工作。

def drawer(x,y):
    pygame.draw.circle(screen,(0,0),[int(x),int(y)],20)

def main():
 running = True
    while running:

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
                exit()
            if event.type == pygame.MOUSEBUTTONDOWN:
                playerY_change = -player.vy
            if event.type == pygame.MOUSEBUTTONUP:
                playerY_change = player.vy
   player.y += PlayerY_change
   drawer(player.x,player.y)
   
   # Other game code
   pygame.display.update()

现在，只要您按住按钮，我希望它仅在每次点击时改变，玩家的运动就会不断变化。我该怎么办？

解决方法

一旦设置了 playerY_change，玩家就会连续移动。因此不要设置playerY_change，而是在鼠标点击时更改player.y：

def main():
 running = True
    while running:

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            if event.type == pygame.MOUSEBUTTONDOWN:
                player.y -= player.vy
            
   drawer(player.x,player.y)
   
   # Other game code
   pygame.display.update()

pygame.quit()
exit()
