How to implement Tetris dodge game based on Python

Tetris is a classic puzzle game, first developed by Russian Alexei Pajitnov in 1984. It is said that his inspiration came from his childhood experience of building blocks. The game first became popular on computers in the Soviet Union and later became popular around the world. Its original design intention is to train players' reaction speed and spatial imagination through this game.

For many people born in the 1980s, Tetris is a memory of their teenage years. At that time, people did not have as many types of games to choose from now, and Tetris was one of the most popular games. People often get together to play Tetris on Famicom or other game consoles, and spend countless hours together. This kind of game experience is not only the game itself, but also the communication and interaction between people, which has become a precious memory for many people.

I have nothing to do recently, so I played a little dodge game. I hope it will be helpful and inspiring to the friends who saw it. Of course, only a simple function is implemented here, and it also gives other friends room to modify or expand again.

Let’s take a look at the implementation of this code.

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口大小和标题
win_width, win_height = 640, 480
win = pygame.display.set_mode((win_width, win_height))
pygame.display.set_caption("小游戏")

# 设置游戏颜色
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)

# 设置关键物属性
man_width, man_height = 50, 100
man_x, man_y = win_width // 2 - man_width // 2, win_height - man_height
man_vel = 5

# 设置障碍物属性
obstacle_width, obstacle_height = 50, 50
obstacle_x, obstacle_y = random.randint(0, win_width - obstacle_width), 0
obstacle_vel = 2

# 设置字体和文本
font = pygame.font.SysFont(None, 30)
score_text = font.render("得分: 0", True, white)

# 初始化分数和帧率
score = 0
fps = 30
clock = pygame.time.Clock()

# 游戏循环
game_over = False
while not game_over:
    # 设置帧率
    clock.tick(fps)

    # 检测事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 获取键盘输入
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and man_x > 0:
        man_x -= man_vel
    if keys[pygame.K_RIGHT] and man_x < win_width - man_width:
        man_x += man_vel

    # 移动障碍物
    obstacle_y += obstacle_vel

    # 判断是否碰撞
    if obstacle_y > man_y:
        if man_x < obstacle_x < man_x + man_width or man_x < obstacle_x + obstacle_width < man_x + man_width:
            game_over = True

    # 判断障碍物是否移出屏幕
    if obstacle_y > win_height:
        obstacle_x, obstacle_y = random.randint(0, win_width - obstacle_width), 0
        score += 1
        score_text = font.render("得分: " + str(score), True, white)

    # 绘制屏幕
    win.fill(black)
    pygame.draw.rect(win, red, (man_x, man_y, man_width, man_height))
    pygame.draw.rect(win, white, (obstacle_x, obstacle_y, obstacle_width, obstacle_height))
    win.blit(score_text, (10, 10))
    pygame.display.update()

# 退出 Pygame
pygame.quit()

Rendering

In this sample code, we use the clock.tick(fps) function to limit the game frame The fps rate controls how fast the game runs. In the game loop, use the pygame.time.Clock().tick(fps) function to pause the game for a period of time after each loop ends so that the frame rate of the game will not be too high.

In addition, we also use Pygame's font module to display scores. Each time a score is scored, the score text will be re-rendered and the display updated.

After this modification, the game should run at a relatively stable speed. You can adjust the frame rate as needed to control the running speed of the game. You can modify and extend the code to your needs to achieve more complex and interesting gameplay.
