Python 实现消消乐小游戏

简介

消消乐（Match-3）是一款经典的益智游戏，核心玩法是通过交换相邻的方块，使三个或更多相同颜色的方块连成一线从而消除得分。本文使用 Python 和 Pygame 库实现一个基础的消消乐游戏，涵盖游戏界面绘制、网格管理、方块交换、匹配检测及消除逻辑。

环境准备

在开始之前，请确保已安装 Python 环境并安装 Pygame 库：

pip install pygame

项目结构与常量定义

游戏主体主要由窗口设置、网格系统、计分器和计时器组成。首先定义全局常量和必要的导入模块。

导入依赖

import os
import sys
import time
import pygame
import random

常量配置

设定窗口大小、网格行列数及边距等参数，便于后续调整。

WIDTH = 400
HEIGHT = 400
NUMGRID = 8
GRIDSIZE = 36
XMARGIN = (WIDTH - GRIDSIZE * NUMGRID) // 2
YMARGIN = (HEIGHT - GRIDSIZE * NUMGRID) // 2
ROOTDIR = os.getcwd()
FPS = 30

游戏主窗口初始化

使用 Pygame 初始化显示模式并设置窗口标题。

pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('消消乐')

网格与方块绘制

绘制网格背景

在主循环中填充背景色，并调用绘制函数画出 8x8 的网格线。

screen.fill((255, 255, 220))

def drawGrids(self):
    for x in range(NUMGRID):
        for y in range(NUMGRID):
            rect = pygame.Rect(
                XMARGIN + x * GRIDSIZE,
                YMARGIN + y * GRIDSIZE,
                GRIDSIZE, GRIDSIZE
            )
            self.drawBlock(rect, color=(, , ), size=)

 ():
    pygame.draw.rect(.screen, color, block, size)

def removeMatched(self, res_match): if res_match[0] > 0: self.generateNewGems(res_match) self.score += self.reward return self.reward return 0 def generateNewGems(self, res_match): if res_match[0] == 1: # 横向消除 start = res_match[2] while start > -2: for each in [res_match[1], res_match[1]+1, res_match[1]+2]: gem = self.getGemByPos(*[each, start]) if start == res_match[2]: self.gems_group.remove(gem) self.all_gems[each][start] = None elif start >= 0: gem.target_y += GRIDSIZE gem.fixed = False gem.direction = 'down' self.all_gems[each][start+1] = gem else: gem = Puzzle( img_path=random.choice(self.gem_imgs), size=(GRIDSIZE, GRIDSIZE), position=[XMARGIN + each * GRIDSIZE, YMARGIN - GRIDSIZE], downlen=GRIDSIZE ) self.gems_group.add(gem) self.all_gems[each][start+1] = gem start -= 1 elif res_match[0] == 2: # 纵向消除 start = res_match[2] while start > -4: if start == res_match[2]: for each in range(0, 3): gem = self.getGemByPos(*[res_match[1], start+each]) self.gems_group.remove(gem) self.all_gems[res_match[1]][start+each] = None elif start >= 0: gem = self.getGemByPos(*[res_match[1], start]) gem.target_y += GRIDSIZE * 3 gem.fixed = False gem.direction = 'down' self.all_gems[res_match[1]][start+3] = gem else: gem = Puzzle( img_path=random.choice(self.gem_imgs), size=(GRIDSIZE, GRIDSIZE), position=[XMARGIN + res_match[1] * GRIDSIZE, YMARGIN + start * GRIDSIZE], downlen=GRIDSIZE * 3 ) self.gems_group.add(gem) self.all_gems[res_match[1]][start+3] = gem start -= 1
