pygame精灵协助

Question

我基本上才刚开始使用PyGame进行开发，而整个Sprite概念都遇到了麻烦。我一直在到处寻找有关如何使用它的指南，但似乎找不到任何指南。我想知道所有工作原理的基本概念。这是我一直在努力的代码：#!/usr/bin/pythonimport pygame, sysfrom pygame.locals import *size = width, height = 320, 320clock = pygame.time.Clock()xDirection = 0yDirection = 0xPosition = 32yPosition = 256blockAmount = width/32pygame.init()screen = pygame.display.set_mode(size)screen.fill([0, 155, 255])pygame.display.set_caption("Mario Test")background = pygame.Surface(screen.get_size())mainCharacter = pygame.sprite.Sprite()mainCharacter.image = pygame.image.load("data/character.png").convert()mainCharacter.rect = mainCharacter.image.get_rect()mainCharacter.rect.topleft = [xPosition, yPosition]screen.blit(mainCharacter.image, mainCharacter.rect)grass = pygame.sprite.Sprite()grass.image = pygame.image.load("data/grass.png").convert()grass.rect = grass.image.get_rect()for i in range(blockAmount):    blockX = i * 32    blockY = 288    grass.rect.topleft = [blockX, blockY]    screen.blit(grass.image, grass.rect)grass.rect.topleft = [64, 256]  screen.blit(grass.image, grass.rect.topleft )running = Falsejumping = False falling = Falsestanding = Truejumpvel = 22gravity = -1while True:    for event in pygame.event.get():        if event.type == KEYDOWN and event.key == K_ESCAPE:            pygame.quit()            sys.exit()        elif event.type == QUIT:            pygame.quit()            sys.exit()        if event.type == KEYDOWN:            if event.key == K_LEFT:                running = True                xRun = -5            elif event.key == K_RIGHT:                running = True                xRun = 5            elif event.key == K_UP or event.key == K_SPACE:                jumping = True        elif event.type == KEYUP:            if event.key == K_LEFT or event.key == K_RIGHT:                running = False基本上，我只是想知道如何将这些草块组合成一个精灵，这样当我添加播放器（也是精灵）时，我可以通过碰撞系统确定他是否在空中。有人可以向我解释我将如何做。我所寻找的基本上只是一个启动器，因为我认为某些文档非常糟糕，因为它不能完全告诉您如何使用它。任何帮助是极大的赞赏 ：）
