# Bedrock Allow Deny Border ## English A faithful, **client-side Fabric mod for Minecraft Java Edition 1.21** that ports the Bedrock / Education Edition **Allow**, **Deny**, and **Border** blocks to Java Edition. Designed specifically for single-player adventure maps and **LAN co-op worldbuilding**. Every rule is evaluated consistently across all clients, and host configurations are synchronized live to everyone on the LAN. > **Note**: In LAN worlds, all participating players must have the same mod version installed for permissions and barrier rules to be enforced uniformly. ### 🧱 What Does It Add? Three "teacher-block" style utility blocks in a dedicated creative tab: | Block | Purpose & Behavior | | :--- | :--- | | **Allow Block** | Marks its vertical column as buildable even within restricted areas. | | **Deny Block** | Prohibits block placement and breaking throughout the entire column (highest stacked block takes precedence). | | **Border Block** | Creates an invisible impassable wall covering the **entire (X, Z) column across all Y levels** (cannot be jumped over, flown over, or tunneled beneath). | *All utility blocks are blast-resistant, unmovable by pistons, and immune to griefing.* ### 🛡️ Border Passing Matrix The border wall operates in two distinct modes, configurable in-game: | Entity Type | Bedrock-like (Default) | Block All Entities | | :--- | :---: | :---: | | **Unprivileged Players & Hostile Mobs** | ❌ Blocked | ❌ Blocked | | **Privileged Players** (Whitelist / OP + Creative) | ✅ Allowed | ✅ Allowed | | **Spectator Mode Players** | ✅ Allowed | ✅ Allowed | | **Projectiles** (Arrows, Ender Pearls, Fireballs, etc.) | ✅ Allowed | ❌ Blocked | | **Vex & Ender Dragon** | ✅ Allowed | ❌ Blocked | ### ✨ Key Features - **Column-Based Protection**: Build permissions apply to the entire vertical column above the block, faithfully matching Bedrock Edition mechanics. - **Whole-Column Barrier**: Border walls span from world bottom (Y=-64) to world ceiling (Y=320). - **Flexible Permission Hierarchy**: - Global whitelist (`/allowdeny whitelist ...`) - Per-block NBT whitelist (attached directly to item/block entities) - Operator bypass (OP level 2, optionally requiring Creative mode) - **Visual Cues**: Optional subtle red particles render when players approach invisible border walls. - **Host-to-Client Live Sync**: Config and whitelist updates by the host instantly replicate to all LAN peers. - **In-Game GUI Support**: Direct configuration via the Mods menu when Mod Menu & Cloth Config are installed. ### ⚙️ Configuration & Commands #### Graphical Interface Open **Mods Menu** → Select **Bedrock Allow Deny Border** → Click **Config**. #### In-Game Commands (OP Level 2) ```mcfunction # Switch border barrier behavior mode /allowdeny config borderMode bedrock_like /allowdeny config borderMode block_all_entities # Toggle operator bypass and creative requirements /allowdeny config opBypass /allowdeny config requireCreative # Toggle boundary particle indicator /allowdeny config showBorderEffect # Manage global whitelist /allowdeny whitelist add /allowdeny whitelist remove /allowdeny whitelist list /allowdeny whitelist clear # Query current position rules or reload configuration /allowdeny query /allowdeny reload ``` ### 📦 Requirements | Component | Required Version | | :--- | :--- | | **Minecraft** | Java Edition 1.21 | | **Fabric Loader** | ≥ 0.19.4 | | **Fabric API** | Any compatible 1.21 build | | **Mod Menu** *(Optional)* | 11.x (for in-game config button) | | **Cloth Config** *(Optional)* | 15.x (for in-game config GUI) | ### 🔨 Building from Source Requires **JDK 21+**: ```bash git clone https://github.com/zihan-ds/minecraft-bedrock-adb.git cd minecraft-bedrock-adb ./gradlew build ``` --- ## 中文说明 **Bedrock Allow Deny Border** 是一款专为 **Minecraft Java 版 1.21** 打造的 Fabric **客户端模组**。它完美还原了基岩版 / 教育版中的**允许方块 (Allow)**、**拒绝方块 (Deny)** 与**边界方块 (Border)**，专为单人冒险地图制作与**局域网联机合作**设计。所有规则由各客户端一致判定，房主修改的配置与白名单会自动实时同步给局域网内的所有玩家。 > **注意**：在局域网联机世界中，所有加入的玩家都需要安装相同版本的模组，以确保权限与空气墙阻挡规则在各客户端表现完全一致。 ### 🧱 新增方块与作用在创造模式独立标签页中新增了三种“教师方块”风格的实用功能方块： | 方块 | 功能与核心机制 | | :--- | :--- | | **允许方块 (Allow Block)** | 将其所在垂直列标记为允许建造（即使处于被拒绝的区域内也可生效）。 | | **拒绝方块 (Deny Block)** | 禁止在其整列范围内放置与破坏方块（位置下方最近的规则生效；堆叠时位置最高的方块优先）。 | | **边界方块 (Border Block)** | 在该坐标生成一道**贯穿整列全高度 (所有 Y 轴)** 的隐形阻挡墙——无法通过搭高翻越、飞行越过或向下挖掘绕过。 | *所有实用方块均具备极高的抗爆性能，无法被活塞推动，防止被恶意破坏。* ### 🛡️ 边界阻挡通行矩阵边界方块提供两种不同的运作模式，可在游戏内随时切换： | 实体类型 | 仿基岩版模式 (默认) | 拦截所有实体模式 | | :--- | :---: | :---: | | **无特权玩家 & 敌对生物** | ❌ 拦截阻挡 | ❌ 拦截阻挡 | | **特权玩家** (白名单 / OP + 创造模式) | ✅ 正常通行 | ✅ 正常通行 | | **旁观模式玩家** | ✅ 正常通行 | ✅ 正常通行 | | **弹射物** (箭矢、末影珍珠、恶魂火球等) | ✅ 正常穿过 | ❌ 拦截阻挡 | | **恼鬼 (Vex) & 末影龙** | ✅ 正常穿过 | ❌ 拦截阻挡 | ### ✨ 核心特性 - **整列保护机制**：破坏与建造权限作用于方块上方的整条垂直列，完全还原基岩版原生机制。 - **全高度绝对屏障**：边界墙从世界最底层（Y = -64）一直延伸至世界顶层（Y = 320）。 - **灵活的权限体系**： - 全局白名单（通过 `/allowdeny whitelist ...` 管理） - 方块级 NBT 白名单（直接存储在物品/方块实体中） - 管理员特权绕过（OP 权限等级 2，可选是否强制要求创造模式） - **视觉粒子提示**：当玩家靠近隐形边界墙时，会产生微弱的红色粒子效果以作提示（可配置开关）。 - **局域网实时同步**：房主对配置与白名单的任何改动，均会秒级同步给局域网内的其他客户端。 - **游戏内图形化配置**：安装 Mod Menu 与 Cloth Config 后，可直接在 Mods 界面呼出配置面板。 ### ⚙️ 配置与指令速查 #### 图形化配置界面进入游戏主菜单或暂停菜单 → **Mods (模组)** → 选择 **Bedrock Allow Deny Border** → 点击 **Config (配置)**。 #### 游戏内指令 (需 OP 等级 2) ```mcfunction # 切换边界墙行为模式（仿基岩版 / 拦截所有实体） /allowdeny config borderMode bedrock_like /allowdeny config borderMode block_all_entities # 设置管理员绕过权限及是否强制创造模式 /allowdeny config opBypass /allowdeny config requireCreative # 开关边界隐形墙红色粒子提示效果 /allowdeny config showBorderEffect # 白名单管理（添加/移除/查看列表/清空） /allowdeny whitelist add <玩家名> /allowdeny whitelist remove <玩家名> /allowdeny whitelist list /allowdeny whitelist clear # 查询当前站立位置生效的规则 / 重载配置文件 /allowdeny query /allowdeny reload ``` ### 📦 环境依赖 | 组件 | 要求版本 | | :--- | :--- | | **Minecraft** | Java Edition 1.21 | | **Fabric Loader** | ≥ 0.19.4 | | **Fabric API** | 适配 1.21 的任意正式构建版本 | | **Mod Menu** *(选装)* | 11.x (用于在模组列表显示配置按钮) | | **Cloth Config** *(选装)* | 15.x (用于提供游戏内图形化配置弹窗) | ### 🔨 源码构建指南构建需要安装 **JDK 21+** 环境： ```bash git clone https://github.com/zihan-ds/minecraft-bedrock-adb.git cd minecraft-bedrock-adb ./gradlew build ``` --- ## 📄 License & Credits / 开源许可 -
