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 sysimport timeimport pygamefrom 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)

画已经落下的方块

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)

画单个方块

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)

画得分等信息

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()
