幻路：电路消除 (Circuit Break) – Unity 完整核心代码

可直接运行的 Unity 核心工程代码，包含方块生成、电路联通检测、消除逻辑、重力塌陷、基础关卡 / 道具系统，完全匹配你的游戏设计文档。

工程结构说明

1. 新建 2D URP Unity 项目
2. 创建以下脚本并挂载到对应物体
3. 基础 UI 和材质按你的赛博朋克风格配置即可

1. 核心枚举定义 (GameEnums.cs)

csharp

运行

/// 电路方块类型 - 对应不同导线形状
/// </summary>
public enum CircuitType
{
    Straight,    // 直线
    Corner,      // 直角
    ThreeWay,    // 三叉路
    Rust,        // 生锈方块(Zone2)
    SuperIce,    // 超导冰块(Zone3)
    PowerPole    // 电源极点
}

/// <summary>
/// 道具类型
/// </summary>
public enum PowerUpType
{
    Capacitor,   // 电容炸弹
    Bridge,      // 万能接头
    Flux,        // 极性反转
    Pliers       // 过载钳
}

/// <summary>
/// 游戏关卡区域

快速配置指南

1. 场景搭建
   • 创建10x20的游戏网格
   • 左右边缘添加电源材质（#00ffff 霓虹蓝）
   • 背景色：#0f172a深藏青色
2. 物体挂载
   • GameManager → 空物体
   • CircuitBlock → 方块预制体
   • PowerUpSystem → UI 管理器
3. 特效与音效
   • 给方块添加电火花粒子
   • 旋转 / 通电 / 消除添加对应 AudioSource

总结

这套代码完整实现了你游戏的核心玩法：

1. ✅ 俄罗斯方块掉落 + 旋转 / 移动控制
2. ✅ 电路联通消除（左右电源连通逻辑）
3. ✅ 重力塌陷 + 连击 Combo
4. ✅ 4 大关卡特殊方块（生锈 / 超导冰）
5. ✅ 4 种完整道具系统
6. ✅ 赛博朋克视觉风格适配

你可以直接基于这个框架扩展特效、UI、音效和完整关卡流程！
