开发环境

Python版本：3.6.4

环境搭建

安装Python并添加到环境变量，pip安装需要的相关模块即可。

原理介绍

通过“↑”，“↓”，“←”，“→”，操控紫色的小豆子移动，当然我们一定要注意的是红色的豆子是不能触碰的哟！不然就gg啦。废话不多说，上才艺：

def main():    pygame.init()    screen = pygame.display.set_mode((HEIGHT * BLOCK_SIZE + GAP * 2, WIDTH *BLOCK_SIZE + GAP * 2), 0, 32)    pygame.display.set_caption('吃豆人小游戏——彳余大胆')    # print(WIDTH, HEIGHT)    font1 = pygame.font.SysFont('SimHei', 20)           # 人和恶魔    font2 = pygame.font.SysFont('SimHei', 24)           # 显示结局    win = False    lose = False    curMap = restart()    evils = randomCreateEvils()    pac = Pac(1, 1)    # for evil in evils:    #     print(evil)    # 用来控制移动速度不能太快    last_pac_move_time = time.time()                    # 上一次人移动时间    last_evil_move_time = time.time()                    # 上一次恶魔移动时间    while True:        for event in pygame.event.get():            if event.type == QUIT:                pygame.quit()                sys.exit()            elif event.type == KEYDOWN:                if win or lose:                    if event.key == K_SPACE:                        win = False                        lose = False                        curMap = restart()                        evils = randomCreateEvils()                        pac = Pac(1, 1)        if event.type == KEYDOWN:            if not win and not lose:                if time.time() - last_pac_move_time > 0.1:                    if event.key == K_UP:                        pac = moveUp(pac, curMap)                    elif event.key == K_DOWN:                        pac = moveDown(pac, curMap)                    elif event.key == K_LEFT:                        pac = moveLeft(pac, curMap)                    elif event.key == K_RIGHT:                        pac = moveRight(pac, curMap)                    win = judgeWin(curMap)                    last_pac_move_time = time.time()        if not win and not lose:            if time.time() - last_evil_move_time > 0.5:                evilCatch(evils, pac)                last_evil_move_time = time.time()        draw_map(screen, curMap, font1)        draw_evil(screen, evils, font1)        lose = judgeLose(evils, pac)        if lose:            draw_lose(screen, font2)        if win:            draw_win(screen, font2)        pygame.display.update()

设置地图的大小，背景颜色，豆子的颜色等等：

WIDTH = len(map1)                               # 地图宽度HEIGHT = len(map1[0])                           # 地图高度BLOCK_SIZE = 20                                 # 单位块大小GAP = 5                                         # 地图四周空隙BG_COLOR = (40, 40, 60)                         # 背景颜色PAC_COLOR = (255, 255, 0)                       # 豆子颜色BLOCK_COLOR = (100, 100, 100)                   # 墙颜色MAN_COLOR = (148, 0, 211)                       # 人颜色ENEMY_COLOR = (200, 30, 30)                     # 恶魔颜色INFO_COLOR = (255, 50, 50)                      # 信息颜色PAC_RADIU = 4                                   # 豆子半径EX = int((BLOCK_SIZE - PAC_RADIU) / 2)          # 画豆子的额外计算距离DIRECTION = [[-1, 0], [1, 0], [0, -1], [0, 1]]  # 恶魔随机移动方向

画出地图：

# 画出地图def draw_map(screen, curMap, font):    # 填充背景色    screen.fill(BG_COLOR)    for i in range(WIDTH):        for j in range(HEIGHT):            w = GAP + j * BLOCK_SIZE            h = GAP + i * BLOCK_SIZE            if curMap[i][j] == 0:                # pygame.draw.circle(screen, PAC_COLOR, (w + EX, h + EX), PAC_RADIU, 0)                                # 抗锯齿的圆                pygame.gfxdraw.aacircle(screen, w + EX, h + EX, PAC_RADIU, PAC_COLOR)                pygame.gfxdraw.filled_circle(screen, w + EX, h + EX, PAC_RADIU, PAC_COLOR)            elif curMap[i][j] == 1:                pygame.draw.rect(screen, BLOCK_COLOR, (w, h, BLOCK_SIZE, BLOCK_SIZE), 0)            elif curMap[i][j] == 3:                pygame.gfxdraw.aacircle(screen, w + 10, h + 10, 8, MAN_COLOR)                pygame.gfxdraw.filled_circle(screen, w + 10, h + 10, 8, MAN_COLOR)

总体代码的话就是这些啦：
