Question

我正在制作一个pygame游戏，玩家并不总是移动到我按下的箭头键。这是移动播放器的代码。

def playerstuff(self):
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                self.XChange = 3
            if event.key == pygame.K_LEFT:
                self.XChange = -3
            if event.key == pygame.K_DOWN:
                self.TownYChange = -5
            if event.key == pygame.K_UP:
                self.TownYChange = 5
        if event.type == pygame.KEYUP:
            if event.key == pygame.K_RIGHT:
                self.XChange = 0
            if event.key == pygame.K_LEFT:
                self.XChange = 0
            if event.key == pygame.K_DOWN:
                self.TownYChange = 0
            if event.key == pygame.K_UP:
                self.TownYChange = 0
    if self.TownYChange != 0:
        self.TownY += self.TownYChange
        gameDisplay.blit(Town,(0,self.TownY))
    self.Xpos += self.XChange
    gameDisplay.blit(Town,(self.Xpos,self.Ypos),pygame.Rect(self.Xpos,self.Ypos,40,50))
    gameDisplay.blit(Idle_man,(self.Xpos,self.Ypos))
    pygame.display.update()

这是制作关卡并执行其他操作的代码

def game():         
    gameDisplay.blit(Town,(0,0))
    player1 = Player(width/2,height/2 - 20)
    while True:
        player1.playerstuff()
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
        clock.tick(60)
        pygame.display.update()

我也遇到过这条线的问题：

gameDisplay.blit(Town,(self.Xpos,self.Ypos),pygame.Rect(self.Xpos,self.Ypos,40,50))

我想用这一行来删除角色并重绘他。这条线做了我想做的事情，但是当我踩到背景的绿色部分时，它会用灰色填充玩家周围的空间。

您可能会在全局事件队列中丢弃事件。您检查事件队列两次，一次在playerstuff()，一次在您的全局游戏循环中，但第二次您不处理按键事件。

def game():         
    gameDisplay.blit(Town,(0,0))
    player1 = Player(width/2,height/2 - 20)
    while True:
        player1.playerstuff() # you check the event queue in this method already
        for event in pygame.event.get():
        # gets all the events that are currently in the queue, meaning all
        # that occured since you last checked the queue in playerstuff()
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            # if event.type was a keypress, you dismiss the event here, 
            # causing you to "lose" keystrokes
        clock.tick(60)
        pygame.display.update()

解决方案是只有一个全局事件队列并处理那里的所有按键。
