我是python和pygame的初学者，我一直在制作一个2D自上而下的游戏（非常类似于《塞尔达传奇》）。我只制作了开始屏幕和第一个屏幕，你可以在那里到处跑，但fps处于20度以下，我想知道我能做些什么来提高它。我根本不知道该做什么

执行而不是的代码总是最快的

正如拉比76所建议的，你每一帧都暂停/取消暂停音乐，这是没有必要的。使用KEYUP事件触发它：

        if event.key == pygame.K_i:
            inv += 1
            if ( inv % 2 ):
                arangeinventory = False
                accessinventory = False
                pygame.mixer.music.unpause()
            else:
                arangeinventory = True
                accessinventory = True
                pygame.mixer.music.pause()

当你blit一个图像时，PyGame需要将其转换为与目标表面相同的格式。你可以做一次，也可以每次都做。我个人喜欢一次：

walkRight = [ pygame.image.load('Wraith/Wraith_01.png').convert_alpha(), 
              pygame.image.load('Wraith/Wraith_02.png').convert_alpha(),
              ...

别忘了convert()你的背景和健康栏图片也要

在这个动画加载中有很多代码，为什么要在已有的重复帧中加载呢？目前，您正在加载和存储同一帧集四次。当然，它不会在播放过程中减慢执行速度，但会不必要地使用资源。只加载您需要的图像。12点循环，而不是48点

walkRight = []
for i in range( 1, 13 ):
    filename = 'Wraith_%02d.png' % ( i )
    filename = os.path.join( 'Wraith', filename ) 
    frame = pygame.image.load( filename ).convert_alpha()
    walkRight.append( frame )
 ### etc. for left and idle.

要绘制健康条，您需要做3个独立的blit()。也许您可以预先创建一个健康栏图像列表，只需在屏幕上显示一次

您似乎没有使用太多的else逻辑。这对执行时间的影响非常小，但是如果在一个紧密的循环中，它会无缘无故地进行比较检查。例如，考虑你的方向代码：

if move_right == False and move_left == False:
    screen.blit(idle[walkCount], (playerx, playery))
    walkCount += 1
if move_right:
    screen.blit(walkRight[walkCount], (playerx, playery))
    walkCount += 1
if move_left:
    screen.blit(walkLeft[walkCount], (playerx, playery))
    walkCount += 1

玩家可以同时向左和向右行走吗；对吧?？如果我们已经检查过玩家没有移动，为什么还要再次测试

if move_right:
    screen.blit(walkRight[walkCount], (playerx, playery))  # go right
elif move_left:
    screen.blit(walkLeft[walkCount], (playerx, playery))   # go left
else:
    screen.blit(idle[walkCount], (playerx, playery))       # idle
walkCount += 1

与事件逻辑类似，单个事件不能有超过1个键值，请使用if/elif/else，以便进行较少的检查。一旦得出结果，就不再进行进一步的测试

        if event.key == pygame.K_a:
            move_left = True
            move_right = False
        elif event.key == pygame.K_d:
            move_right = True
            move_left = False
        elif event.key == pygame.K_w:
            move_up = True
        ... etc.
