html 写的俄罗斯方块游戏
5星 · 资源好评率100%
HTML 是一种标记语言,主要用于网页的布局和呈现,无法直接实现游戏逻辑和交互等方面的功能。如果您想要编写一个完整的俄罗斯方块游戏,需要借助其他编程语言和技术,如 JavaScript、CSS、Canvas 等。下面是一个简单的 HTML、CSS 和 JavaScript 代码示例,可以实现一个基本的俄罗斯方块游戏:
HTML 代码:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>俄罗斯方块游戏</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="game-container">
<canvas id="game-canvas"></canvas>
<div id="game-info">
<h1>俄罗斯方块游戏</h1>
<p>得分:<span id="score">0</span></p>
<p>下一个方块:</p>
<canvas id="next-canvas"></canvas>
<button id="start-button">开始游戏</button>
</div>
</div>
<script src="game.js"></script>
</body>
</html>
```
CSS 代码:
```css
body {
margin: 0;
padding: 0;
font-family: Arial, sans-serif;
background-color: #f5f5f5;
}
#game-container {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
#game-canvas {
background-color: #fff;
border: 2px solid #ccc;
}
#game-info {
margin-left: 50px;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}
#game-info h1 {
margin: 0;
font-size: 36px;
}
#game-info p {
margin: 10px 0;
font-size: 24px;
}
#game-info #score {
font-weight: bold;
color: #f00;
}
#game-info #next-canvas {
background-color: #fff;
border: 2px solid #ccc;
margin-top: 10px;
}
#game-info #start-button {
margin-top: 20px;
padding: 10px 20px;
font-size: 24px;
background-color: #f00;
color: #fff;
border: none;
border-radius: 10px;
cursor: pointer;
}
```
JavaScript 代码:
```javascript
