draw_cells

`draw_cells`通常指的是在编程中用于绘制网格或单元格的函数，这通常与图形界面(GUI)编程、数据可视化或者游戏开发中的场景有关。这个函数可能是用来在屏幕上显示网格结构，每个单元格可能有不同的颜色、形状或者代表特定的数据状态。它可能会接受参数来控制网格的大小、线条样式、填充颜色等。

例如，在Python的Tkinter库中，你可能会看到这样的函数，用于在一个窗口上绘制一个由小格子组成的矩阵：

import tkinter as tk

def draw_cells(window, cell_size, color):
    for row in range(num_rows):
        for col in range(num_cols):
            cell = tk.Canvas(window, width=cell_size, height=cell_size)
            cell.create_rectangle(col * cell_size, row * cell_size, (col + 1) * cell_size, (row + 1) * cell_size, fill=color)
            cell.pack()

好的，为了添加图形设计界面和计分系统，我们需要使用Python中的GUI库。这里我们选择使用Pygame库来实现游戏界面和计分系统。

首先，我们需要安装Pygame库。在命令行中输入以下命令：

pip install pygame

安装完成后，我们可以开始编写代码了。

首先，我们需要导入Pygame库并初始化它：

import pygame

pygame.init()

然后，我们需要定义一些常量来表示游戏界面的大小和颜色：

SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480
CELL_SIZE = 80
CELL_PADDING = 20
BACKGROUND_COLOR = (250, 248, 239)
CELL_COLORS = {
    0: (205, 193, 180),
    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)
}

其中，SCREEN_WIDTH和SCREEN_HEIGHT分别表示游戏界面的宽度和高度，CELL_SIZE和CELL_PADDING分别表示每个方格的大小和间距，BACKGROUND_COLOR表示游戏界面的背景色，CELL_COLORS是一个字典，用于表示不同数字的方格的颜色。

接下来，我们需要定义一些函数来绘制游戏界面和方格：

def draw_board(board, screen):
    screen.fill(BACKGROUND_COLOR)
    for i in range(4):
        for j in range(4):
            cell_color = CELL_COLORS[board[i][j]]
            cell_rect = pygame.Rect(j * (CELL_SIZE + CELL_PADDING) + CELL_PADDING, i * (CELL_SIZE + CELL_PADDING) + CELL_PADDING, CELL_SIZE, CELL_SIZE)
            pygame.draw.rect(screen, cell_color, cell_rect)
            if board[i][j] != 0:
                font = pygame.font.SysFont(None, int(CELL_SIZE * 0.4))
                text = font.render(str(board[i][j]), True, (255, 255, 255))
                text_rect = text.get_rect(center=cell_rect.center)
                screen.blit(text, text_rect)

def draw_score(score, screen):
    font = pygame.font.SysFont(None, 50)
    text = font.render("Score: {}".format(score), True, (0, 0, 0))
    text_rect = text.get_rect(center=(SCREEN_WIDTH // 2, SCREEN_HEIGHT - 50))
    screen.blit(text, text_rect)

其中，draw_board函数用于绘制游戏界面，draw_score函数用于绘制得分。

然后，我们需要修改一下add_new函数，让它返回新生成的数字的位置：

def add_new(board):
    empty_cells = []
    for i in range(4):
        for j in range(4):
            if board[i][j] == 0:
                empty_cells.append((i, j))
    if empty_cells:
        i, j = random.choice(empty_cells)
        board[i][j] = 2 if random.random() < 0.9 else 4
        return (i, j)
    else:
        return None

接着，我们需要修改main函数，让它使用Pygame库来显示游戏界面和得分：

def main():
    board = init_board()
    add_new(board)
    add_new(board)

    score = 0

    screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
    pygame.display.set_caption("2048")

    while not is_game_over(board):
        draw_board(board, screen)
        draw_score(score, screen)
        pygame.display.flip()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_a:
                    move_left(board)
                    add_new_pos = add_new(board)
                elif event.key == pygame.K_d:
                    move_right(board)
                    add_new_pos = add_new(board)
                elif event.key == pygame.K_w:
                    move_up(board)
                    add_new_pos = add_new(board)
                elif event.key == pygame.K_s:
                    move_down(board)
                    add_new_pos = add_new(board)
                else:
                    add_new_pos = None

                if add_new_pos:
                    score += board[add_new_pos[0]][add_new_pos[1]]

        pygame.display.flip()

    draw_board(board, screen)
    draw_score(score, screen)

    font = pygame.font.SysFont(None, 50)
    text = font.render("Game Over!", True, (255, 0, 0))
    text_rect = text.get_rect(center=(SCREEN_WIDTH // 2, SCREEN_HEIGHT // 2))
    screen.blit(text, text_rect)

    pygame.display.flip()

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

最后，我们需要在代码开头添加以下代码来保证程序正确运行：

if __name__ == "__main__":
    main()

这样，我们就完成了2048游戏的图形界面和计分系统的添加。完整代码如下：

mxgraph加载drawio

MXGraph是一个强大的JavaScript库，用于创建交互式的图形编辑器和流程图工具。Draw.io是一个在线绘图工具，提供了类似Visio的界面，用于制作图表、流程图和其他类型的图形。

如果你想在MXGraph中集成Draw.io的内容或样式，MXGraph本身并不直接支持Draw.io文件的导入，但你可以通过一些步骤间接实现这种功能：

1. 将Draw.io生成的SVG或者JSON导出文件转换：Draw.io的图形可以导出为SVG或JSON格式，这两个格式都可以被MXGraph识别。你需要使用第三方工具或者开发一个脚本来将Draw.io的图形数据转换成MXGraph能理解的格式。

2. 数据解析：将导出的SVG或JSON数据解析成MXGraph可以处理的对象模型（通常是GraphModel或者cells）。

3. 加载到MXGraph：将解析后的数据添加到MXGraph的画布上，作为新节点、边或连接。

4. 适应MXGraph交互：可能需要对Draw.io的样式进行调整，使其符合MXGraph的交互模式，如缩放、拖拽等。
