pygame窗口显示“无响应”

如何解决pygame窗口显示“无响应”

当我运行pygame程序时，游戏窗口显示无响应，并且我还编写了退出功能，但我不知道为什么它的广告再次显示无响应 我的笔记本电脑是Windows 8和32位

    import pygame

#initializing pygame
pygame.init()

# create game screen
screen = pygame.display.set_mode((800,600))

# Title and Icon
pygame.display.set_caption("Space Invader")
icon = pygame.image.load('spaceship.png')
pygame.display.set_icon(icon)

# Player
playerImg = pygame.image.load('player.png')
playerX = 370
playerY = 480
playerX_change = 0

def player(x,y):
    screen.blit(playerImg,(x,y))

# Game Loop
running = True
while running:

    # RGB - Red,Green,Blue
    screen.fill((0,0))
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

        # if keystroke is pressed check the weather its right or left
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                playerX_change = -0.1
            if event.key == pygame.K_RIGHT:
                playerX_change = 0.1 
        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                playerX_change = 0.1
        
        # 5 = 5 + -0.1 -> 5 = 5 - 0.1
        # 5 = 5 + 0.1
        playerX += player_change
        player(playerX,playerY)

        pygame.display.update()
    
       

解决方法

这是Indentation的问题。您必须在应用程序循环而不是事件循环中更新显示。
此外，变量的名称是playerX_change而不是player_change，并且在释放键时，必须设置playerX_change = 0.0而不是playerX_change = 0.1：

running = True
while running:

    # RGB - Red,Green,Blue
    screen.fill((0,0))
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

        # if keystroke is pressed check the weather its right or left
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                playerX_change = -0.1
            if event.key == pygame.K_RIGHT:
                playerX_change = 0.1 
        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                playerX_change = 0.0 # <---- 0.0 instead of 0.1


    #<--| INDENTATION
    # 5 = 5 + -0.1 -> 5 = 5 - 0.1
    # 5 = 5 + 0.1
    playerX += playerX_change
    player(playerX,playerY)

    pygame.display.update()
