Question

当我使用screen.fill制作背景时，我的代码正在检查英雄与大量射弹的碰撞-程序仍然没有滞后。但是当我决定添加绘制的背景（3600x1200 pix）作为精灵时，fps下降到约20 fps。我删除了所有弹丸，但fps仍然非常低。选择如此大的背景来移动它，而不是移动主要英雄。这是我的代码和显示背景的问题行（没有它，一切都很好）。

    settings = Settings()
    screen = pg.display.set_mode((settings.screen_width,settings.screen_height))
    pg.display.set_caption(settings.caption)
    hero = Hero(0, 0, "Right", 1/240, pg.image.load('images/hero/hero1.png'), 128, 16, 15, 0.08, 0.2, settings,27)

        hero.orientation()
        #screen filling with backgroung color
        screen.fill([255, 255, 255])
        screen.blit(bg.image, bg.rect)
        #displaying projectiles(walls,floor,etc.)
        for projectile in projectiles:
            projectile.display(screen)
        #displaying hero image and all his atributes
        hero.display(screen, myfont)
        gf.command_block_draw(settings,myfont,screen,cl)
        #test string for displaying problematic variables
        gf.test_string_draw(settings,myfont,hero,screen)
        #display updating
        pg.display.flip()
    #quit
    pg.quit()

#running game
run_game()

行：

screen.blit(bg.image, bg.rect)

BackGround类：

import pygame as pg

class Background(pg.sprite.Sprite):
    def __init__(self, image_file, location):
        pg.sprite.Sprite.__init__(self)
        self.image = pg.image.load(image_file)
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = location

确保对图像进行convert（）。

更改这一行代码将大大提高您的性能。

它可以将Surface转换为pygame预先喜欢的格式，从而加快所有后续的blit。
