象棋对弈python代码

以下是一个简单的 Python 代码实现象棋双人对战的示例：

import pygame

# 定义棋盘大小和格子大小
SCREEN_SIZE = WIDTH, HEIGHT = 720, 720
GRID_SIZE = CELL_WIDTH, CELL_HEIGHT = 80, 80
ROWS, COLS = 9, 8

# 定义棋子类型
KING, ADVISOR, ELEPHANT, HORSE, CHARIOT, CANNON, SOLDIER = range(7)

# 定义棋子颜色
RED, BLACK = 0, 1

# 定义棋子图片
PIECE_IMAGES = {
    (KING, RED): pygame.image.load("red_king.png"),
    (ADVISOR, RED): pygame.image.load("red_advisor.png"),
    (ELEPHANT, RED): pygame.image.load("red_elephant.png"),
    (HORSE, RED): pygame.image.load("red_horse.png"),
    (CHARIOT, RED): pygame.image.load("red_chariot.png"),
    (CANNON, RED): pygame.image.load("red_cannon.png"),
    (SOLDIER, RED): pygame.image.load("red_soldier.png"),
    (KING, BLACK): pygame.image.load("black_king.png"),
    (ADVISOR, BLACK): pygame.image.load("black_advisor.png"),
    (ELEPHANT, BLACK): pygame.image.load("black_elephant.png"),
    (HORSE, BLACK): pygame.image.load("black_horse.png"),
    (CHARIOT, BLACK): pygame.image.load("black_chariot.png"),
    (CANNON, BLACK): pygame.image.load("black_cannon.png"),
    (SOLDIER, BLACK): pygame.image.load("black_soldier.png"),
}

# 定义棋子初始位置
INITIAL_POSITIONS = [
    (CHARIOT, RED, (0, 0)), (HORSE, RED, (0, 1)), (ELEPHANT, RED, (0, 2)),
    (ADVISOR, RED, (0, 3)), (KING, RED, (0, 4)), (ADVISOR, RED, (0, 5)),
    (ELEPHANT, RED, (0, 6)), (HORSE, RED, (0, 7)), (CHARIOT, RED, (0, 8)),
    (CANNON, RED, (2, 1)), (CANNON, RED, (2, 7)),
    (SOLDIER, RED, (3, 0)), (SOLDIER, RED, (3, 2)), (SOLDIER, RED, (3, 4)),
    (SOLDIER, RED, (3, 6)), (SOLDIER, RED, (3, 8)),
    (CHARIOT, BLACK, (9, 0)), (HORSE, BLACK, (9, 1)), (ELEPHANT, BLACK, (9, 2)),
    (ADVISOR, BLACK, (9, 3)), (KING, BLACK, (9, 4)), (ADVISOR, BLACK, (9, 5)),
    (ELEPHANT, BLACK, (9, 6)), (HORSE, BLACK, (9, 7)), (CHARIOT, BLACK, (9, 8)),
    (CANNON, BLACK, (7, 1)), (CANNON, BLACK, (7, 7)),
    (SOLDIER, BLACK, (6, 0)), (SOLDIER, BLACK, (6, 2)), (SOLDIER, BLACK, (6, 4)),
    (SOLDIER, BLACK, (6, 6)), (SOLDIER, BLACK, (6, 8))
]

# 定义棋盘二维数组，表示棋子位置
board = [[None] * COLS for _ in range(ROWS)]

# 初始化棋子位置
for piece_type, piece_color, piece_pos in INITIAL_POSITIONS:
    row, col = piece_pos
    board[row][col] = (piece_type, piece_color)

# 初始化 pygame
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode(SCREEN_SIZE)
pygame.display.set_caption("Chinese Chess")

# 主循环
running = True
selected_piece = None  # 被选中的棋子
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:  # 左键点击
                x, y = event.pos
                row, col = y // CELL_HEIGHT, x // CELL_WIDTH
                piece = board[row][col]
                if piece:  # 点击有棋子的格子
                    if piece == selected_piece:  # 取消选择
                        selected_piece = None
                    else:  # 选择棋子
                        selected_piece = piece
                elif selected_piece:  # 移动棋子
                    row0, col0 = selected_piece_pos = selected_piece_pos(row, col)
                    if can_move(board, selected_piece, selected_piece_pos):
                        board[row][col] = selected_piece
                        board[row0][col0] = None
                        selected_piece = None

    # 绘制棋盘和棋子
    for row in range(ROWS):
        for col in range(COLS):
            x, y = col * CELL_WIDTH, row * CELL_HEIGHT
            pygame.draw.rect(screen, (255, 255, 255), (x, y, CELL_WIDTH, CELL_HEIGHT))
            piece = board[row][col]
            if piece:
                piece_type, piece_color = piece
                image = PIECE_IMAGES[piece_type, piece_color]
                screen.blit(image, (x, y))

    # 绘制选中框
    if selected_piece:
        row, col = selected_piece_pos
        x, y = col * CELL_WIDTH, row * CELL_HEIGHT
        pygame.draw.rect(screen, (255, 0, 0), (x, y, CELL_WIDTH, CELL_HEIGHT), 3)

    # 刷新屏幕
    pygame.display.flip()

# 退出游戏
pygame.quit()

上述代码中，棋盘使用二维数组表示，棋子使用类似元组的数据结构表示，棋子图片使用字典表示，棋子初始位置使用常量列表表示。在主循环中，处理鼠标事件，根据鼠标点击的位置选择或移动棋子，然后绘制棋盘和棋子。
