使用Pyglet制作“彩色方块连连看”游戏（续）

在前面的部分，我们已经构建了游戏的基本框架，并实现了方块的随机生成和显示。接下来，我们将继续开发这款连连看游戏，实现方块的点击和消除功能。以下是具体的步骤和代码示例。

环境准备

确保你已经安装了Pyglet库，可以通过以下命令进行安装：

pip install pyglet

然后，创建一个新的Python文件，比如lianliankan.py，并导入所需的模块。

import pyglet
import random

继续上一步的游戏设计

我们将定义一些常量，比如窗口的宽度和高度，以及方块的大小。然后，创建一个用于存储方块的容器。

# 游戏设置
WINDOW_WIDTH = 400
WINDOW_HEIGHT = 400
BLOCK_SIZE = 40
GRID_WIDTH = WINDOW_WIDTH // BLOCK_SIZE
GRID_HEIGHT = WINDOW_HEIGHT // BLOCK_SIZE

# 颜色
COLORS = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0),
          (255, 165, 0), (128, 0, 128), (0, 255, 255), (255, 20, 147)]

# 创建窗口
window = pyglet.window.Window(WINDOW_WIDTH, WINDOW_HEIGHT)

# 创建网格数据
grid = [[None for _ in range(GRID_WIDTH)] for _ in range(GRID_HEIGHT)]

初始化游戏网格

我们需要初始化游戏的网格，并为每个方块随机赋予一种颜色。

def init_grid():
    for row in range(GRID_HEIGHT):
        for col in range(GRID_WIDTH):
            # 随机选择颜色
            color = random.choice(COLORS)
            grid[row][col] = color

# 初始化
init_grid()

渲染方块

我们需要在窗口上绘制这些方块。重写on_draw事件来实现这一功能。

@window.event
def on_draw():
    window.clear()
    for row in range(GRID_HEIGHT):
        for col in range(GRID_WIDTH):
            color = grid[row][col]
            pyglet.graphics.draw(4, pyglet.gl.GL_QUADS,
                                 ('v2f', [col * BLOCK_SIZE, row * BLOCK_SIZE,
                                           col * BLOCK_SIZE, (row + 1) * BLOCK_SIZE,
                                           (col + 1) * BLOCK_SIZE, (row + 1) * BLOCK_SIZE,
                                           (col + 1) * BLOCK_SIZE, row * BLOCK_SIZE]),
                                 ('c3B', color * 4))

处理点击事件

为了实现点击方块的功能，我们需要添加一个鼠标事件侦听器来检测玩家的点击。

selected_block = None

@window.event
def on_mouse_press(x, y, button, modifiers):
    global selected_block
    col = x // BLOCK_SIZE
    row = y // BLOCK_SIZE

    if 0 <= col < GRID_WIDTH and 0 <= row < GRID_HEIGHT:
        if selected_block is None:
            selected_block = (row, col)  # 选中方块
        else:
            if grid[row][col] == grid[selected_block[0]][selected_block[1]]:
                # 消除方块
                grid[selected_block[0]][selected_block[1]] = None
                grid[row][col] = None
            selected_block = None  # 重置选中

主循环

最后，我们需要启动主循环，保持窗口的打开状态。

pyglet.app.run()

完整代码

将以上所有代码整合在一起，形成完整的lianliankan.py文件。运行程序，你会看到一个400x400的窗口，里面有彩色方块。点击相同颜色的方块，能够将其消除。

import pyglet
import random

# 游戏设置
WINDOW_WIDTH = 400
WINDOW_HEIGHT = 400
BLOCK_SIZE = 40
GRID_WIDTH = WINDOW_WIDTH // BLOCK_SIZE
GRID_HEIGHT = WINDOW_HEIGHT // BLOCK_SIZE

COLORS = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0),
          (255, 165, 0), (128, 0, 128), (0, 255, 255), (255, 20, 147)]

window = pyglet.window.Window(WINDOW_WIDTH, WINDOW_HEIGHT)
grid = [[None for _ in range(GRID_WIDTH)] for _ in range(GRID_HEIGHT)]
selected_block = None

def init_grid():
    for row in range(GRID_HEIGHT):
        for col in range(GRID_WIDTH):
            color = random.choice(COLORS)
            grid[row][col] = color

init_grid()

@window.event
def on_draw():
    window.clear()
    for row in range(GRID_HEIGHT):
        for col in range(GRID_WIDTH):
            color = grid[row][col]
            pyglet.graphics.draw(4, pyglet.gl.GL_QUADS,
                                 ('v2f', [col * BLOCK_SIZE, row * BLOCK_SIZE,
                                           col * BLOCK_SIZE, (row + 1) * BLOCK_SIZE,
                                           (col + 1) * BLOCK_SIZE, (row + 1) * BLOCK_SIZE,
                                           (col + 1) * BLOCK_SIZE, row * BLOCK_SIZE]),
                                 ('c3B', color * 4))

@window.event
def on_mouse_press(x, y, button, modifiers):
    global selected_block
    col = x // BLOCK_SIZE
    row = y // BLOCK_SIZE

    if 0 <= col < GRID_WIDTH and 0 <= row < GRID_HEIGHT:
        if selected_block is None:
            selected_block = (row, col)
        else:
            if grid[row][col] == grid[selected_block[0]][selected_block[1]]:
                grid[selected_block[0]][selected_block[1]] = None
                grid[row][col] = None
            selected_block = None

pyglet.app.run()

通过这段代码，你已经实现了一个基础的“彩色方块连连看”游戏。可以继续扩展游戏，比如增加计时器、分数系统、重新开始游戏等功能，让游戏更加丰富和有趣。希望你能享受这个开发的过程！
