python制作俄罗斯方块
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

draw_cells(canvas, 3, 13, SHAPES['T'], SHAPESCOLOR['T'])
draw_cells(canvas, 8, 3, SHAPES['I'], SHAPESCOLOR['I'])

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。

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。
