用python编写中国象棋，规则完善，用turtle库编写

以下是一个使用 Python 的`turtle`库编写的简单中国象棋程序示例。这个程序实现了基本的棋盘绘制和棋子放置功能，同时包含了一些简单的走子规则判断，但并没有实现完整的中国象棋规则（如吃子、将军、困毙等复杂规则）。 ```python import turtle # 棋盘尺寸 BOARD_SIZE = 9 GRID_SIZE = 60 BOARD_WIDTH = GRID_SIZE * (BOARD_SIZE - 1) BOARD_HEIGHT = GRID_SIZE * 10 # 棋子类 class ChessPiece: def __init__(self, name, color, x, y): self.name = name self.color = color self.x = x self.y = y self.piece = turtle.Turtle() self.piece.shape("circle") self.piece.color(color) self.piece.penup() self.piece.goto(x, y) self.piece.write(name, align="center", font=("Arial", 18, "bold")) def move(self, new_x, new_y): # 简单的走子规则判断，这里只是示例，未实现完整规则 if self.name in ["车", "炮"]: # 车和炮只能直线移动 if new_x == self.x or new_y == self.y: self.piece.goto(new_x, new_y) self.x = new_x self.y = new_y elif self.name == "马": # 马走日 dx = abs(new_x - self.x) dy = abs(new_y - self.y) if (dx == 2 and dy == 1) or (dx == 1 and dy == 2): self.piece.goto(new_x, new_y) self.x = new_x self.y = new_y # 绘制棋盘 def draw_board(): board = turtle.Turtle() board.speed(0) board.penup() board.goto(-BOARD_WIDTH / 2, -BOARD_HEIGHT / 2) board.pendown() # 绘制横线 for i in range(10): board.penup() board.goto(-BOARD_WIDTH / 2, -BOARD_HEIGHT / 2 + i * GRID_SIZE) board.pendown() board.forward(BOARD_WIDTH) # 绘制竖线 for i in range(BOARD_SIZE): board.penup() board.goto(-BOARD_WIDTH / 2 + i * GRID_SIZE, -BOARD_HEIGHT / 2) board.pendown() board.setheading(90) board.forward(BOARD_HEIGHT) board.setheading(0) # 绘制楚河汉界 river = turtle.Turtle() river.penup() river.goto(-BOARD_WIDTH / 2, -BOARD_HEIGHT / 2 + 5 * GRID_SIZE) river.pendown() river.write("楚河 汉界", align="center", font=("Arial", 36, "bold")) # 初始化棋子 def init_pieces(): pieces = [] # 红方棋子 pieces.append(ChessPiece("车", "red", -BOARD_WIDTH / 2, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("马", "red", -BOARD_WIDTH / 2 + GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("相", "red", -BOARD_WIDTH / 2 + 2 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("仕", "red", -BOARD_WIDTH / 2 + 3 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("帅", "red", -BOARD_WIDTH / 2 + 4 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("仕", "red", -BOARD_WIDTH / 2 + 5 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("相", "red", -BOARD_WIDTH / 2 + 6 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("马", "red", -BOARD_WIDTH / 2 + 7 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("车", "red", -BOARD_WIDTH / 2 + 8 * GRID_SIZE, BOARD_HEIGHT / 2 - GRID_SIZE)) pieces.append(ChessPiece("炮", "red", -BOARD_WIDTH / 2 + GRID_SIZE, BOARD_HEIGHT / 2 - 2 * GRID_SIZE)) pieces.append(ChessPiece("炮", "red", -BOARD_WIDTH / 2 + 7 * GRID_SIZE, BOARD_HEIGHT / 2 - 2 * GRID_SIZE)) for i in range(0, 9, 2): pieces.append(ChessPiece("兵", "red", -BOARD_WIDTH / 2 + i * GRID_SIZE, BOARD_HEIGHT / 2 - 3 * GRID_SIZE)) # 黑方棋子 pieces.append(ChessPiece("车", "black", -BOARD_WIDTH / 2, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("马", "black", -BOARD_WIDTH / 2 + GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("象", "black", -BOARD_WIDTH / 2 + 2 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("士", "black", -BOARD_WIDTH / 2 + 3 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("将", "black", -BOARD_WIDTH / 2 + 4 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("士", "black", -BOARD_WIDTH / 2 + 5 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("象", "black", -BOARD_WIDTH / 2 + 6 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("马", "black", -BOARD_WIDTH / 2 + 7 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("车", "black", -BOARD_WIDTH / 2 + 8 * GRID_SIZE, -BOARD_HEIGHT / 2 + GRID_SIZE)) pieces.append(ChessPiece("炮", "black", -BOARD_WIDTH / 2 + GRID_SIZE, -BOARD_HEIGHT / 2 + 2 * GRID_SIZE)) pieces.append(ChessPiece("炮", "black", -BOARD_WIDTH / 2 + 7 * GRID_SIZE, -BOARD_HEIGHT / 2 + 2 * GRID_SIZE)) for i in range(0, 9, 2): pieces.append(ChessPiece("卒", "black", -BOARD_WIDTH / 2 + i * GRID_SIZE, -BOARD_HEIGHT / 2 + 3 * GRID_SIZE)) return pieces # 鼠标点击事件处理 def click_handler(x, y): global selected_piece if selected_piece is None: for piece in pieces: if abs(x - piece.x) < GRID_SIZE / 2 and abs(y - piece.y) < GRID_SIZE / 2: selected_piece = piece break else: selected_piece.move(x, y) selected_piece = None # 主函数 if __name__ == "__main__": screen = turtle.Screen() screen.title("中国象棋") draw_board() pieces = init_pieces() selected_piece = None screen.onscreenclick(click_handler) screen.mainloop() ``` 代码说明： 1. 棋盘绘制：`draw_board`函数使用`turtle`库绘制了中国象棋的棋盘，包括横线、竖线和楚河汉界。 2. 棋子类：`ChessPiece`类表示一个棋子，包含棋子的名称、颜色、位置等属性，以及移动方法`move`。 3. 初始化棋子：`init_pieces`函数初始化了红方和黑方的棋子，并将它们放置在棋盘上。 4. 鼠标点击事件处理：`click_handler`函数处理鼠标点击事件，实现了棋子的选择和移动。 5. 主函数：在`__main__`部分，创建了一个`turtle`屏幕，调用`draw_board`和`init_pieces`函数，设置鼠标点击事件处理函数，并启动主循环。 注意事项： - 这个程序只是一个简单的示例，没有实现完整的中国象棋规则，如吃子、将军、困毙等。 - 可以根据需要进一步扩展`ChessPiece`类的`move`方法，实现更复杂的走子规则。 [2025-11-22 11:28:14 | AI问答 | 2127点数解答]
