用python写一个俄罗斯方块小游戏

相信大家都玩过俄罗斯方块吧，应该是小时候的回忆吧，但是想不想了解一下这个程序是怎么写出来的呢，自己写出来的应该玩起来更有感觉吧！

感觉还是蛮好玩吧！

接下来，我就分享一下这个游戏的源码过程啊！

先用python创建一个py文件

定义这次程序所需要的类

import sys

import time

import pygame

from pygame.localsimport *

import blocks

然后写出它所需要的模块

SIZE =30 # 每个小方格大小

BLOCK_HEIGHT =25 # 游戏区高度

BLOCK_WIDTH =10 # 游戏区宽度

BORDER_WIDTH =4 # 游戏区边框宽度

BORDER_COLOR = (40, 40, 200)# 游戏区边框颜色

SCREEN_WIDTH = SIZE * (BLOCK_WIDTH +5)# 游戏屏幕的宽

SCREEN_HEIGHT = SIZE * BLOCK_HEIGHT# 游戏屏幕的高

BG_COLOR = (40, 40, 60)# 背景色

BLOCK_COLOR = (20, 128, 200)#

BLACK = (0, 0, 0)

RED = (200, 30, 30)# GAME OVER 的字体颜色

 

 

# 画背景

```python

```python
def _draw_background(screen):
# 填充背景色
screen.fill(BG_COLOR)
# 画游戏区域分隔线
pygame.draw.line(screen, BORDER_COLOR,
(SIZE * BLOCK_WIDTH + BORDER_WIDTH // 2, 0),
(SIZE * BLOCK_WIDTH + BORDER_WIDTH // 2, SCREEN_HEIGHT), BORDER_WIDTH)

 

# 画网格线

```python
def _draw_gridlines(screen):
# 画网格线 竖线
for x in range(BLOCK_WIDTH):
pygame.draw.line(screen, BLACK, (x * SIZE, 0), (x * SIZE, SCREEN_HEIGHT), 1)
# 画网格线 横线
for y in range(BLOCK_HEIGHT):
pygame.draw.line(screen, BLACK, (0, y * SIZE), (BLOCK_WIDTH * SIZE, y * SIZE), 1)

 

def _draw_game_area(screen, game_area):
if game_area:
for i, row in enumerate(game_area):
for j, cell in enumerate(row):
if cell != '.':
pygame.draw.rect(screen, BLOCK_COLOR, (j * SIZE, i * SIZE, SIZE, SIZE), 0)

 

def _draw_block(screen, block, offset_x, offset_y, pos_x, pos_y):
if block:
for i in range(block.start_pos.Y, block.end_pos.Y + 1):
for j in range(block.start_pos.X, block.end_pos.X + 1):
if block.template[i][j] != '.':
pygame.draw.rect(screen, BLOCK_COLOR,
(offset_x + (pos_x + j) * SIZE, offset_y + (pos_y + i) * SIZE, SIZE, SIZE), 0)

 

def _draw_info(screen, font, pos_x, font_height, score):
print_text(screen, font, pos_x, 10, f'得分: ')
print_text(screen, font, pos_x, 10 + font_height + 6, f'{score}')
print_text(screen, font, pos_x, 20 + (font_height + 6) * 2, f'速度: ')
print_text(screen, font, pos_x, 20 + (font_height + 6) * 3, f'{score // 10000}')
print_text(screen, font, pos_x, 30 + (font_height + 6) * 4, f'下一个：')

if __name__ == '__main__':
main()
