Pygame真的很慢

[英]Pygame Being Really Slow

我在pygame中有一個程序。 我有許多不同的部分,其中兩個如下所示。 在第二個游戲中,游戲的運行速度正常,但是在第一個游戲中,即使它具有相同的滴答速度,也非常落后。 有什么我想念的嗎? 順便說一下,每個游戲循環周期中只有一個被執行。 請注意,以#結尾的行在兩者之間重復。

for event in pygame.event.get():#
    if event.type==pygame.QUIT:#
        pygame.quit()#
        sys.exit()#
    if event.type==pygame.KEYDOWN:#
        if event.key==pygame.K_ESCAPE:#
            pygame.quit()#
            sys.exit()#
for ball in balls:#
    ball.update(winrect, walls)#
window.fill(WHITE)#
for box in boxes:#
    pygame.draw.rect(window, box[1], box[0])#
for wall in walls:#
    if wall.orientation==0:#
        pygame.draw.rect(window, BLACK, (wall.left, wall.top, wall.ttopleft, wall.height))#
        pygame.draw.rect(window, BLACK, (wall.bbottomright, wall.top, wall.right-wall.bbottomright, wall.height))#
    else:#
        pygame.draw.rect(window, BLACK, (wall.left, wall.top, wall.width, wall.ttopleft))#
        pygame.draw.rect(window, BLACK, (wall.left, wall.bbottomright, wall.width, wall.bottom-wall.holesize))#
for ball in balls:#
    pygame.draw.circle(window, ball.color, ball.center, round(ball.width/2))#
    pygame.draw.circle(window, BLACK, ball.center, round(ball.width/2), 2)#
window.blit(coverso, winrect)
window.blit(texts['complete'][0], texts['complete'][1])
window.blit(stuff[0], stuff[1])
pygame.display.update()#
pygame.time.Clock().tick(100)#

第二個:

    #event loop
    for event in pygame.event.get():#
        if event.type==pygame.QUIT:#
            pygame.quit()#
            sys.exit()#
        if event.type==pygame.KEYDOWN:#
            if event.key==pygame.K_ESCAPE:#
                mode='pause'#
    #updates
    updates=[]
    for wall in walls:
        wall.update()
    for ball in balls:#
        updates.append(ball.update(winrect, walls))#similar
    #Seeing if won
    won=True
    for update in updates:
        if not update:
            won=False
    if won:
        if levels[loadinglevel][4]==0:
            levels[loadinglevel][4]=1
        levels[loadinglevel-1][4]=2
        mode='complete'
        stuff=getcomplete(loadinglevel, coins, bigfont, texts['complete'][1].bottom+100, winrect.centerx)
        for wall in walls:
            wall.bbottomright=100000
            wall.ttopleft=90000
        coins+=loadinglevel
    #blitting
    window.fill(WHITE)#
    for box in boxes:#
        pygame.draw.rect(window, box[1], box[0])#
    for wall in walls:#
        if wall.orientation==0:#
            pygame.draw.rect(window, BLACK, (wall.left, wall.top, wall.ttopleft, wall.height))#
            pygame.draw.rect(window, BLACK, (wall.bbottomright, wall.top, wall.right-wall.bbottomright, wall.height))#
        else:#
            pygame.draw.rect(window, BLACK, (wall.left, wall.top, wall.width, wall.ttopleft))#
            pygame.draw.rect(window, BLACK, (wall.left, wall.bbottomright, wall.width, wall.bottom-wall.holesize))#
    for ball in balls:#
        pygame.draw.circle(window, ball.color, ball.center, round(ball.width/2))#
        pygame.draw.circle(window, BLACK, ball.center, round(ball.width/2), 2)#
    pygame.display.update()#
    pygame.time.Clock().tick(100)#
    if mode=='pause':
        window.blit(coverso, winrect)

在第一部分中唯一不重復的行是:

window.blit(coverso, winrect)
window.blit(texts['complete'][0], texts['complete'][1])
window.blit(stuff[0], stuff[1])

如果不使用Alpha ,建議您在創建曲面時使用surface.convert()

如果您使用Alpha,則可以使用色鍵,因為它們 Alpha曲面要快得多

為了加快計算速度,我建議使用Psyco

http://www.psyco.sourceforge.net/

除了alexpinho98所說的,您不必在alpha曲面上使用色鍵。 您可以改用surface.convert_alpha()。

使用以下代碼可以節省一些時間,並使您不必重復鍵入.convert_alpha():

def loadify(imgname):
    return pygame.image.load(imagename).convert_alpha()
