使用HTML5画布技术制作一款拼图小游戏,要求将图像划分为3X3共9块方块并打乱排序每个方块间有分隔线,用户可以移动方块拼成完整图片

使用HTML5画布技术制作一款拼图小游戏,可以按照以下步骤进行:
准备工作:
- 准备一张图片作为拼图的素材。
- 创建一个HTML文件和一个JavaScript文件。
HTML结构:
- 创建一个
<canvas>
元素用于绘制拼图。 - 添加一些按钮用于控制游戏,例如重置按钮。
- 创建一个
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>拼图游戏</title>
<style>
canvas {
border: 1px solid black;
}
#controls {
margin-top: 10px;
}
</style>
</head>
<body>
<canvas id="gameCanvas" width="300" height="300"></canvas>
<div id="controls">
<button id="resetButton">重置</button>
</div>
<script src="puzzle.js"></script>
</body>
</html>
- JavaScript逻辑:
- 初始化画布和图片。
- 将图片划分为3X3共9块方块。
- 打乱方块的顺序。
- 处理用户点击事件,移动方块。
// puzzle.js
const canvas = document.getElementById('gameCanvas');
const ctx = canvas.getContext('2d');
const resetButton = document.getElementById('resetButton');
const rows = 3;
const cols = 3;
const image = new Image();
image.src = 'path_to_your_image.jpg'; // 替换为你的图片路径
let tiles = [];
let emptyTile = { x: cols - 1, y: rows - 1 };
image.onload = function() {
initializeTiles();
shuffleTiles();
drawTiles();
};
function initializeTiles() {
for (let y = 0; y < rows; y++) {
for (let x = 0; x < cols; x++) {
tiles.push({ x, y, imgX: x, imgY: y });
}
}
}
function shuffleTiles() {
for (let i = 0; i < 1000; i++) {
let neighbors = getNeighbors(emptyTile);
let randomNeighbor = neighbors[Math.floor(Math.random() * neighbors.length)];
swapTiles(emptyTile, randomNeighbor);
}
}
function getNeighbors(tile) {
let neighbors = [];
if (tile.x > 0) neighbors.push({ x: tile.x - 1, y: tile.y });
if (tile.x < cols - 1) neighbors.push({ x: tile.x + 1, y: tile.y });
if (tile.y > 0) neighbors.push({ x: tile.x, y: tile.y - 1 });
if (tile.y < rows - 1) neighbors.push({ x: tile.x, y: tile.y + 1 });
return neighbors;
}
function swapTiles(tile1, tile2) {
let temp = tiles.find(t => t.x === tile1.x && t.y === tile1.y);
let other = tiles.find(t => t.x === tile2.x && t.y === tile2.y);
[temp.x, other.x] = [other.x, temp.x];
[temp.y, other.y] = [other.y, temp.y];
}
function drawTiles() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
for (let tile of tiles) {
ctx.drawImage(image, tile.imgX * (image.width / cols), tile.imgY * (image.height / rows), image.width / cols, image.height / rows, tile.x * (canvas.width / cols), tile.y * (canvas.height / rows), canvas.width / cols, canvas.height / rows);
}
}
canvas.addEventListener('click', function(event) {
const rect = canvas.getBoundingClientRect();
const x = Math.floor((event.clientX - rect.left) / (canvas.width / cols));
const y = Math.floor((event.clientY - rect.top) / (canvas.height / rows));
let clickedTile = tiles.find(t => t.x === x && t.y === y);
let neighbors = getNeighbors(clickedTile);
if (neighbors.some(t => t.x === emptyTile.x && t.y === emptyTile.y)) {
swapTiles(clickedTile, emptyTile);
emptyTile = clickedTile;
drawTiles();
}
});
resetButton.addEventListener('click', function() {
shuffleTiles();
drawTiles();
});
