利用python制作俄罗斯方块详细图文教程

作者:极客李华

俄罗斯方块是一款经典的游戏,它可以用多种编程语言来实现,这篇文章主要给大家介绍了关于利用python制作俄罗斯方块的详细图文教程,文中通过代码介绍的非常详细,需要的朋友可以参考下

简介

俄罗斯方块》(Tetris, 俄文:Тетрис)是一款由俄罗斯人阿列克谢·帕基特诺夫于1984年6月发明的休闲游戏。

该游戏曾经被多家公司代理过。经过多轮诉讼后,该游戏的代理权最终被任天堂获得。 [1] 任天堂对于俄罗斯方块来说意义重大,因为将它与GB搭配在一起后,获得了巨大的成功。 [1]

《俄罗斯方块》的基本规则是移动、旋转和摆放游戏自动输出的各种方块,使之排列成完整的一行或多行并且消除得分。

编码

搭建基础页面

首先是创建一个python文件

创建一个窗体,用来显示这个游戏的界面

代码

import tkinter as tk
# 首先创建一个窗体
win = tk.Tk()
win.mainloop()

运行结果

绘制格子

原理如下

画格子,这里主要应用的是tkinter里面Canvas功能。

代码如下

import tkinter as tk

# 设置行数和列数
row = 20
col = 12

# 设置每个格子的大小
cell_size = 30

# 设置窗口的高和宽
height = row * cell_size
width = col * cell_size

# 首先创建一个窗体
win = tk.Tk()

# 在画板上绘制格子
def draw_cell(canvas, col, row, color="#CCCCCC"):
    x0 = col * cell_size
    y0 = row * cell_size

    x1 = col * cell_size + cell_size
    y1 = row * cell_size + cell_size

    # 创建矩形
    canvas.create_rectangle(x0, y0, x1, y1, fill=color, outline="white", width=2)

def draw_blank_board(canvas):
    for ri in range(row):
        for cj in range(col):
            draw_cell(canvas, cj, ri)


# 绘制画布的长宽
canvas = tk.Canvas(win, width=width, height=height)

# 打包放置组件对象
canvas.pack()

draw_blank_board(canvas)

win.mainloop()

绘制俄罗斯方块

现根据这个规则绘制一个看看情况

代码讲解

import tkinter as tk

# 设置行数和列数
Row = 20
Col = 12

# 设置每个格子的大小
cell_size = 30

# 设置窗口的高和宽
height = Row * cell_size
width = Col * cell_size

# 设置不同形状的格子
SHAPES = {
    "O": [(-1, -1), (0, -1), (-1, 0), (0, 0)]
}

# 设置格子的颜色
SHAPESCOLOR = {
    "O":"blue"
}

# 在画板上绘制格子
def draw_cell_background(canvas, col, row, color="#CCCCCC"):
    x0 = col * cell_size
    y0 = row * cell_size

    x1 = col * cell_size + cell_size
    y1 = row * cell_size + cell_size

    # 创建矩形
    canvas.create_rectangle(x0, y0, x1, y1, fill=color, outline="white", width=2)

def draw_blank_board(canvas):
    for ri in range(Row):
        for cj in range(Col):
            draw_cell_background(canvas, cj, ri)

def draw_cells(canvas, col, row, cell_list, color="#CCCCCC"):
    """
    :param canvas: 画板对象
    :param col: 这个形状的的原点所在的列
    :param row: 这个形状所的原点所在的行
    :param cell_list: 这个形状各个格子相对于自身的原点所处的位置坐标
    :param color: 这个形状的颜色
    :return:
    """
    for cell in cell_list:
        cell_col, cell_row = cell
        ci = cell_col + col
        ri = cell_row + row
        # 判断是否越界
        if 0 <= col < Col and 0 <= row < Row:
            draw_cell_background(canvas, ci, ri, color)

# 首先创建一个窗体
win = tk.Tk()

# 绘制画布的长宽
canvas = tk.Canvas(win, width=width, height=height)

# 打包放置组件对象
canvas.pack()

# 画背景
draw_blank_board(canvas)

# 开始画图形了, 这里是先测试一下
draw_cells(canvas, 3, 3, SHAPES['O'], SHAPESCOLOR['O'])


win.mainloop()

运行结果,通过运行结果可以看出来没有太大的问题

绘制其他的样式的格子

这里是其他的格子的各种坐标,只需要往上面的代码中的SHAPES和SHAPESCOLOR中放就可以了。

演示代码

import tkinter as tk

# 设置行数和列数
Row = 20
Col = 12

# 设置每个格子的大小
cell_size = 30

# 设置窗口的高和宽
height = Row * cell_size
width = Col * cell_size

# 设置不同形状的格子
SHAPES = {
    "O": [(-1, -1), (0, -1), (-1, 0), (0, 0)],
    "S":[(-1, 0),(0, 0),(0, -1),(1, -1)],
    "T":[(-1, 0),(0, 0),(0, -1),(1, 0)],
    "I":[(0, 1),(0, 0),(0, -1),(0, -2)],
    "L":[(-1, 0),(0, 0),(-1, -1),(-1, -2)],
    "J":[(-1, 0),(0, 0),(0, 1),(0, -2)],
    "Z":[(-1, -1),(0, -1),(0, 0),(1, 0)]

# 设置格子的颜色

    "O":"blue",
    "S":"red",

    for cell in cell_list:

        ri = cell_row + row
        # 判断是否越界
        if 0 <= col < Col and 0 <= row < Row:
            draw_cell_background(canvas, ci, ri, color)

# 首先创建一个窗体
win = tk.Tk()

# 绘制画布的长宽
canvas = tk.Canvas(win, width=width, height=height)

# 打包放置组件对象
canvas.pack()

# 画背景
draw_blank_board(canvas)

# 开始画图形了, 这里是先测试一下
draw_cells(canvas, 3, 3, SHAPES['O'], SHAPESCOLOR['O'])
draw_cells(canvas, 3, 8, SHAPES['S'], SHAPESCOLOR['S'])
draw_cells(canvas, 3, 13, SHAPES['T'], SHAPESCOLOR['T'])
draw_cells(canvas, 8, 3, SHAPES['I'], SHAPESCOLOR['I'])
draw_cells(canvas, 8, 8, SHAPES['L'], SHAPESCOLOR['L'])
draw_cells(canvas, 8, 13, SHAPES['J'], SHAPESCOLOR['J'])
draw_cells(canvas, 5, 18, SHAPES['Z'], SHAPESCOLOR['Z'])


win.mainloop()

运行结果

通过测试这个各种的图形格子是完成了的。

让格子动起来

让这个格子使人感觉动起来,主要的原理就是设置一个刷新时间,然后这个格子不断的加载,然后不断的刷新,这样是利用的是game_loop(),draw_block_move(canvas, block, direction=[0,0])两个函数。

Col = 12

# 设置每个格子的大小

# 设置窗口的高和宽
height = Row * cell_size

    "J":[(-1, 0),(0, 0),(0, 1),(0, -2)],
    "Z":[(-1, -1),(0, -1),(0, 0),(1, 0)]
}

# 设置格子的颜色
SHAPESCOLOR = {
    "O":"blue",

    new_c, new_r = c + dc, r + dr
    block['cr'] = [new_c, new_r]
    draw_cells(canvas, new_c, new_r, cell_list, SHAPESCOLOR[shape_type])

# 用字典定义每个形状的属性

    'kind': 'O', # 对应俄罗斯方块的类型
    'cell_list': SHAPES['O'], # 对应的每个俄罗斯方块的坐标

draw_block_move(canvas, one_block)
# 让游戏不断循环 通过递归实现
def game_loop():
    win.update()

    # 往下走
    down = [0, 1]
    draw_block_move(canvas, one_block, down)
    win.after(FPS, game_loop) # 注意的是这个game_loop后面不能加括号

game_loop()
win.mainloop()

运行结果

这里生成了一个,往下掉的小俄罗斯方块。

在这这里我们实现了这个俄罗斯方块的不断的生成,和俄罗斯方块的不断的叠加,基本实现了俄罗斯方块的生产功能。

运行结果

移动

运行结果

这个效果就是可以左右移动,具体代码看下面,主要依靠的是horizontal_move_block(event)这个函数的实现。

运行结果

这个是游戏最后的样子,其实可以后面再加一个数据库的功能,记录每一次的得分结果。
