俄罗斯方块python小程序（免费）

学习前的准备

1. python编译器
2. pygame库和random库
3. 清醒的头脑
4. 一双能三连实践的双手

让我们开始吧

导入

import pygame
from pygame import locals
import random
pygame.init()   # 初始化

pygame库可以做一些小游戏，如果报这个错的话(见#1)就打开cmd，输入(见#2)就可以解决了。

#1：

ModuleNotFoundError: No module named 'pygame'

#2：

pip install pygame

 创建窗口

# 创建窗口
screen = pygame.display.set_mode((460, 500))
pygame.display.set_caption("俄罗斯方块")
clock = pygame.time.Clock()  # pygame时钟，控制游戏速度（帧数）

载入

素材

# 载入素材
background = pygame.image.load('bg.png')
font = pygame.font.Font('STKAITI.TTF', 60)  # 字体
fontovor = pygame.font.Font('STKAITI.TTF', 100)

素材都打包进了俄罗斯方块python小程序（免费）-Python文档类资源-CSDN下载

 形状

颜色

# 一些RGB颜色

    (204, 153, 153), (102, 102, 153),(153, 0, 102),

        # 当前的小方块超出网格的行、列，就返回False

主体

循环

while True:

侦测

    for event in pygame.event.get():
        if event.type == locals.QUIT:
            exit()
        if event.type == locals.KEYDOWN:
            if gameovor==True:
                gameovor=False
            if event.key == locals.K_LEFT:    # 向左
                center[1] = center[1] - 1       # 左移1列
                if check(center) == False:
                    center[1] = center[1] + 1   # 右移1列

            elif event.key == locals.K_RIGHT:     # 向右
                center[1] = center[1] + 1
                if check(center) == False:
                    center[1] = center[1] - 1
                    
            elif event.key == locals.K_DOWN:    # 向下
                center[0] = center[0] + 1
                if check(center) == False:
                    center[0] = center[0] - 1
            
            elif event.key == locals.K_UP:      # 向上键
                old_index = index
                index += 1
                if index >= len(shape):
                    index = 0
                current_shape = shape[index]
                if check(center) == False:
                    index = old_index
                    current_shape = shape[index]

此处左右键移动，下键加速，上键旋转。

游玩

游戏结束为假    

    if gameovor==False:

方块掉落

        if states == False:

覆盖背景图

        # 将背景图画上去
        screen.blit(background, (0, 0))

计算方块位置

        # 计算出所有小方块的行、列位置

绘制方块

得分

        # 得分
        text_surface = font.render(str(score), True, (0, 0, 0))
        screen.blit(text_surface, (350,70))

游戏结束

    if gameovor==True:

画面刷新

    # 刷新画面
    pygame.display.update()
    clock.tick(FPS)

现在游戏就做完了，敬请大家一键扇脸。
