用python写一个2048小游戏

好的，我可以为您提供一些Python代码来实现2048小游戏。您可以使用Pygame模块创建游戏窗口并实现游戏逻辑。

以下是一个简单的示例代码：

import pygame
import random

# 游戏窗口的大小
WIDTH = 400
HEIGHT = 400

# 游戏方格的大小
CELL_SIZE = 100

# 游戏方格的颜色
COLORS = {
    2: (238, 228, 218),
    4: (237, 224, 200),
    8: (242, 177, 121),
    16: (245, 149, 99),
    32: (246, 124, 95),
    64: (246, 94, 59),
    128: (237, 207, 114),
    256: (237, 204, 97),
    512: (237, 200, 80),
    1024: (237, 197, 63),
    2048: (237, 194, 46),
}

# 游戏方格的字体
FONT = pygame.font.Font(None, 40)

# 初始化游戏方格
grid = [[0 for y in range(4)] for x in range(4)]

# 在游戏方格中随机生成一个新方块
def new_block():
    while True:
        x = random.randint(0, 3)
        y = random.randint(0, 3)
        if grid[x][y] == 0:
            grid[x][y] = 2 if random.random() < 0.9 else 4
            break

# 在游戏窗口中绘制游戏方格
def draw_grid(screen):
    for x in range(4):
        for y in range(4):
            color = COLORS.get(grid[x][y], (255, 255, 255))
            pygame.draw.rect(screen, color, (x * CELL_SIZE, y * CELL_SIZE, CELL_SIZE, CELL_SIZE))
            if grid[x][y]:
                text = FONT.render(str(grid[x][y]), True, (0, 0, 0))
                text_rect = text.get_rect(center=(x * CELL_SIZE + CELL_SIZE / 2, y * CELL_SIZE + CELL_SIZE / 2))
                screen.blit(text, text_rect)

# 判断游戏是否结束
def is_game_over():
    for x in range(4):
        for y in range(4):
            if grid[x][y] == 0:
                return False
            if x < 3 and grid[x][y] == grid[x + 1][y]:
                return False
            if y < 3 and grid[x][y] == grid[x][y + 1]:
                return False
    return True

# 向上移动游戏方格
def move_up():
    global grid
    for y in range(4):
        for x in range(4):
            if grid[x][y] == 0:
                continue
            for i in range(x):
                if grid[i][y] == 0:
                    grid[i][y] = grid[x][y]
                    grid[x][y] = 0
                    break
                if grid[i][y] == grid[x][y]:
                    grid[i][y] *= 2
                    grid[x][y] = 0
                    break

# 向下移动游戏方格
def move_down():
    global grid
    for y in range(4):
        for x in range(3, -1, -1):
            if grid[x][y] == 0:
                continue
            for i in range(x + 1, 4):
                if grid[i][y] == 0:
                    grid[i][y] = grid[x][y]
                    grid[x][y] = 0
                    break
                if grid[i][y] == grid[x][y]:
                    grid[i][y] *= 2
                    grid[x][y] = 0
                    break

# 向左移动游戏方格
def move_left():
    global grid
    for x in range(4):
        for y in range(4):
            if grid[x][y] == 0:

                if grid[x][i] == 0:
                    grid[x][i] = grid[x][y]
                    grid[x][y] = 0
                    break
                if grid[x][i] == grid[x][y]:
                    grid[x][i] *= 2
                    grid[x][y] = 0
                    break

# 向右移动游戏方格
def move_right():
    global grid
    for x in range(4):
        for y in range(3, -1, -1):
            if grid[x][y] == 0:
                continue
            for i in range(y + 1, 4):
                if grid[x][i] == 0:
                    grid[x][i] = grid[x][y]

                    grid[x][y] = 0
                    break

# 初始化Pygame
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode((WIDTH, HEIGHT))

# 设置窗口标题
pygame.display.set_caption("2048")

# 随机生成两个新方块
new_block()
new_block()

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP:
                move_up()

    # 绘制游戏方格
    draw_grid(screen)

    # 显示屏幕
    pygame.display.flip()

这个示例代码可以实现一个简单的2048小游戏，您可以根据自己的需要进行修改和扩展。
