🔧 分步教程

index.html — 主 HTML 文件。
style.css — CSS 样式。
script.js — JavaScript 代码。

制作 HTML 结构

首先，我们将设置基本的 HTML 结构，包括游戏画布、HUD （Heads-Up Display）和叠加层元素。

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Futuristic Neon Space Shooter Game</title><link href="https://fonts.googleapis.com/css2?family=Orbitron:wght@700&display=swap" rel="stylesheet"><link rel="stylesheet" href="style.css">
</head>
<body><!-- Futuristic Overlay Elements -->

</div><div class="game-container"><!-- Heads-Up Display (HUD) --><div class="hud"><div class="score">Score: <span id="score">0</span></div><div class="lives">Lives: <span id="lives">3</span></div><div class="instructions"><div class="control"><span class="icon">⬆️⬇️⬅️➡️</span><span class="text">Move</span></div><div class="control"><span class="icon">⎵</span><span class="text">Shoot</span></div></div></div><!-- Game Canvas --><canvas id="gameCanvas"></canvas><!-- Game Over Screen --><div class="game-over" id="gameOver"><h1>Game Over</h1><p>Your Score: <span id="finalScore"></span></p><button id="restartButton">Restart</button></div>
</div><!-- Futuristic Background Elements -->
<div class="background-elements"><!-- Animated Stars --><div class="stars"></div><!-- Glowing Nebula --><div class="nebula"></div>
</div><script src="script.js"></script>
</body>
</html>
</code></span></span>

解释：

未来派叠加元素：这些元素添加了动态视觉效果，如网格和电路。
Game Container：包含 HUD、Game Canvas 和 Game Over 屏幕。
HUD：用极简主义图标显示乐谱、生活和说明。
背景元素：包括动画星星和发光的星云，以增加深度。

使用 CSS 设置样式

接下来，我们将使用 CSS 让游戏栩栩如生，增强视觉效果以实现未来主义的霓虹灯美学。

解释：

全局样式：使用径向渐变设置深色背景，并应用 Orbitron 字体以获得未来感。
HUD 样式：位于左上角，具有霓虹灯发光效果。说明以极简图标显示。
叠加效果：动画网格和电路可增强未来主义美感。
背景元素：动画星星和发光的星云营造出深度和沉浸感。
响应式设计：媒体查询可针对较小的屏幕调整样式。
