基于SpringBoot和Vue写一个2048小游戏
作者:战族狼魂
创建一个基于 Java Spring Boot 后端和 Vue 前端的 2048 游戏,可以按照以下步骤进行,这个项目将包括后端(用来处理游戏逻辑)和前端(用来显示游戏界面和与用户交互),感兴趣的小伙伴可以参考本文自己动手尝试一下
1. 设置项目结构
你需要创建一个包含两个部分的项目:
- 后端 (Java Spring Boot)
- 前端 (Vue.js)
2. 后端 (Spring Boot)
首先,创建一个新的 Spring Boot 项目。你可以使用 Spring Initializr 或者任何其他你喜欢的方式。
项目依赖
确保添加以下依赖:
Spring Web
Spring Boot DevTools
编写游戏逻辑
在 src/main/java
下创建一个用于处理游戏逻辑的包,例如 com.example.game
.
GameController.java
package com.example.game; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RestController; @RestController public class GameController { private Game game = new Game(); @GetMapping("/game") public int[][] getGameState() { return game.getBoard(); } @PostMapping("/move") public int[][] makeMove(@RequestBody String direction) { switch (direction) { case "up": game.moveUp(); break; case "down": game.moveDown(); break; case "left": game.moveLeft(); break; case "right": game.moveRight(); break; } game.addRandomTile(); return game.getBoard(); } }
Game.java
package com.example.game; import java.util.Random; public class Game { private int[][] board = new int[4][4]; private Random random = new Random(); public Game() { addRandomTile(); addRandomTile(); } public int[][] getBoard() { return board; } public void moveUp() { for (int col = 0; col < 4; col++) { int[] column = new int[4]; int index = 0; for (int row = 0; row < 4; row++) { if (board[row][col] != 0) { column[index++] = board[row][col]; } } merge(column); for (int row = 0; row < 4; row++) { board[row][col] = column[row]; } } } public void moveDown() { for (int col = 0; col < 4; col++) { int[] column = new int[4]; int index = 0; for (int row = 3; row >= 0; row--) { if (board[row][col] != 0) { column[index++] = board[row][col]; } } merge(column); for (int row = 0; row < 4; row++) { board[3 - row][col] = column[row]; } } } public void moveLeft() { for (int row = 0; row < 4; row++) { int[] newRow = new int[4]; int index = 0; for (int col = 0; col < 4; col++) { if (board[row][col] != 0) { newRow[index++] = board[row][col]; } } merge(newRow); board[row] = newRow; } } public void moveRight() { for (int row = 0; row < 4; row++) { int[] newRow = new int[4]; int index = 0; for (int col = 3; col >= 0; col--) { if (board[row][col] != 0) { newRow[index++] = board[row][col]; } } merge(newRow); for (int col = 0; col < 4; col++) { board[row][3 - col] = newRow[col]; } } } private void merge(int[] row) { for (int i = 0; i < 3; i++) { if (row[i] != 0 && row[i] == row[i + 1]) { row[i] *= 2; row[i + 1] = 0; i++; } } int[] newRow = new int[4]; int index = 0; for (int num : row) { if (num != 0) { newRow[index++] = num; } } System.arraycopy(newRow, 0, row, 0, 4); } public void addRandomTile() { int emptyTiles = 0; for (int[] row : board) { for (int tile : row) { if (tile == 0) { emptyTiles++; } } } if (emptyTiles == 0) { return; } int randomTile = random.nextInt(emptyTiles); int value = random.nextInt(10) < 9 ? 2 : 4; for (int i = 0; i < 4; i++) { for (int j = 0; j < 4; j++) { if (board[i][j] == 0) { if (randomTile == 0) { board[i][j] = value; return; } randomTile--; } } } } }
3. 前端 (Vue.js)
创建一个新的 Vue 项目,你可以使用 Vue CLI 或者 Vite 等工具。
设置 Vue 项目
安装 Axios 以便与后端进行通信:
npm install axios
创建游戏界面
在 src/components
目录下创建一个 Game.vue
组件:
<template> <div class="game"> <div class="board"> <div v-for="(row, rowIndex) in board" :key="rowIndex" class="row"> <div v-for="(cell, colIndex) in row" :key="colIndex" class="cell"> {{ cell || '' }} </div> </div> </div> <div class="controls"> <button @click="move('up')">Up</button> <button @click="move('down')">Down</button> <button @click="move('left')">Left</button> <button @click="move('right')">Right</button> </div> </div> </template> <script> import axios from 'axios'; export default { data() { return { board: [[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]] }; }, mounted() { this.getBoard(); }, methods: { async getBoard() { const response = await axios.get('/game'); this.board = response.data; }, async move(direction) { const response = await axios.post('/move', direction); this.board = response.data; } } }; </script> <style> .game { text-align: center; } .board { display: inline-block; } .row { display: flex; } .cell { width: 50px; height: 50px; background-color: #ccc; margin: 5px; display: flex; justify-content: center; align-items: center; font-size: 18px; font-weight: bold; } .controls { margin-top: 20px; } </style>
在 App.vue 中导入 Game.vue
<template> <div id="app"> <Game /> </div> </template> <script> import Game from './components/Game.vue'; export default { name: 'App', components: { Game } }; </script> <style> #app { font-family: Avenir, Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; margin-top: 60px; } </style>
4. 运行和调试
- 启动 Spring Boot 项目。
- 启动 Vue 前端项目。
确保 Spring Boot 的默认端口(8080)与 Vue 的默认端口(通常是8081)不会冲突。
你现在应该能够在浏览器中访问 Vue 前端,并与 Spring Boot 后端进行交互,从而玩 2048 游戏。
