如何让我的 pygame 关卡更有效率？ [关闭]

Question

为了提高效率，我一直在重做我的很多游戏，在我为每个级别设置函数之前，每个级别都有大约 300 多行重复的代码，但我已经把它拿出来了'正在尝试让一级功能正常运行。下面是我的代码，关于如何让我的代码在我运行游戏时玩 level1 的任何帮助，因为现在它只显示背景屏幕，没有敌人、平台或角色。

我认为您应该看看您的“级别”课程。 例如，给它一个适当的 init 方法。 我通过如下修改类来运行游戏：

class levels():
def __init__(self):
    self.levelind = levelInd()
    self.character = Character()
    self.all_sprites = pygame.sprite.Group()
    self.platforms = pygame.sprite.Group()
    self.enemies = pygame.sprite.Group()
    self.bullet_list = pygame.sprite.Group()
    self.background_image = pygame.image.load("1LPqX.png")
    self.score1 = 0
    self.running = True

def run(self):
    while self.running:
        self.level1()
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                self.running = False
                pygame.display.quit()
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_w:
                    self.haracter.characterJump(self.platforms)

            if event.type == pygame.KEYDOWN and event.key == pygame.K_SPACE:

                bullet = Bullet()

                bullet.rect.x = self.character.rect.x + 10
                bullet.rect.y = self.character.rect.y + 50

                self.bullet_list.add(bullet)
                self.all_sprites.add(bullet)

                for bullet in self.bullet_list:

                    # See if the enemy is hit
                    enemyHit = pygame.sprite.spritecollide(bullet, self.enemies, True)
                    if enemyHit:
                        self.enemies.remove(Enemy)
                        self.score1 += 10
                    if bullet.rect.x > 700:
                        self.bullet_list.remove(bullet)

        if self.character.rect.y >= 500:
            self.background_image = pygame.image.load("1LPqX.png")
            pygame.display.update()
            self.all_sprites.empty()

        death = pygame.sprite.spritecollide(self.character, self.enemies, True)
        if len(death) > 0:

            self.background_image = pygame.image.load("1LPqX.png")
            self.all_sprites.empty()

        self.all_sprites.update()

        hits = pygame.sprite.spritecollide(self.character, self.platforms, False)
        for platform in hits:
            if self.character.vel.y > 0:
                self.character.rect.bottom = self.character.rect.bottom
                self.character.vel.y = 0
            elif self.character.vel.y < 0:
                self.character.rect.top = self.character.rect.top
                self.character.vel.y = 3

            self.character.pos.y = self.character.rect.bottom

        screen.blit(self.background_image, [0, 0])
        self.all_sprites.draw(screen)
        pygame.display.flip()

def level1(self):

    done = False
    clock = pygame.time.Clock()
    font_name = pygame.font.match_font("Arial")
    black = (0, 0, 0)
    white = (255, 255, 255)
    x = 300
    y = 88

    e1 = Enemy(250, 125)

    self.enemies.add(e1)

    self.all_sprites.add(self.character)
    self.all_sprites.add(self.levelind)
    self.all_sprites.add(e1)

    p1 = Platform(-80, 400, WIDTH - 400, HEIGHT - 10)
    p2 = Platform(175, 210, WIDTH - 400, HEIGHT - 10)
    p3 = Platform(500, 400, WIDTH - 400, HEIGHT - 10)

    self.all_sprites.add(p1, p2, p3)
    self.platforms.add(p1, p2, p3)

    self.score1 = 0

# level1()

（好像没有正确复制缩进，“class levels()”下面的所有内容都必须缩进4个空格）

添加

if __name__ == '__main__':
    game = levels()
    game.run()

在文件的底部。
