v1.3.3 — Minecraft 1.20–1.20.4 · In-game behavior editor · Smart path smoothing

Three version-specific JARs — pick the one matching your Minecraft version. Requires Java 17+. Builds for Minecraft 1.20.5–1.21.4 (Java 21+ targets) are not published for this release; only 1.20–1.20.4 is supported.

Behavior editor (editor.zip) — the optional offline Blockly editor: download from GitHub release, or grab it under Files → Additional files on any 1.3.3 version page. Unzip it, open editor/behavior-editor.html in your browser, build behaviors with 100+ Scratch-like blocks, save the .json into .minecraft/config/my-bot-mod/behaviors/, then assign it to a bot in game. (v1.3.3 also adds an in-game editor, so the HTML editor is entirely optional.)

Highlights

• Multi-version build system — toolchain upgraded to Gradle 9.7 + Fabric Loom 1.17.19; one codebase builds every target via Stonecutter conditional comments. This release publishes 1.20.1, 1.20.2 and 1.20.4 JARs (Minecraft 1.20–1.20.4).
• In-game behavior editor — write behaviors without leaving the game: category panel, statement list, parameter forms, breadcrumb navigation for nested control flow; output fully compatible with the HTML editor. "Save" writes to the behaviors folder and hot-reloads.
• New export blocks — outputRaw (raw line), outputTemplate (custom template with {time} {bot} {var:name} placeholders), outputTable (custom header + row-append CSV); existing output blocks gain append/overwrite write modes.
• Behavior execution UI rework — live status line with queue progress (x/y), playlist ▲▼ reorder / remove / clear-all, behavior search box, per-row "run only this" and edit shortcuts.
• Creative flight inheritance — bots summoned mid-flight enter flight too; state persisted with preserveBotState.
• Ender chest — /bot <name> enderchest opens the bot's real ender chest for live editing, auto-saved on close.
• Smart path smoothing (pathfindingSmooth, default on) — width-aware line-of-sight merging of waypoints; jump/fall/swim anchors and ravines unaffected.

Pathfinding rework

• Pathfinder rewritten as a synchronous optimized A* with hard caps (15000 iterations / 25000 nodes); old string-pulling smoothing removed in favor of the width-aware smart smoothing.

Removals

• Group & cooperative building system fully removed: /botmod group * and /bot <name> build * commands, related UIs, behavior blocks and config options.
• Carpet compatibility mode removed (carpetModCompatibility): the mod can be installed alongside Carpet.
• Creative-mode restriction on baton teleport removed (allowBatonTeleportNonCreative); dead code removed (onMessage event, ineffective configMenuKey).

Bug fixes

• Right-click panel "Delete bot" button now actually works (via new /bot <name> kill confirm with strictly validated confirmation window).
• Skin priority fixed: local skins/ PNG and Base64 skins now take precedence over the Mojang API — offline play no longer stalls on network timeouts.
• In-game behavior editor UI text is now fully localized (EN/中文).
• Behavior script exceptions no longer crash the server tick; broadcast no longer double-executes; behavior restarts no longer leak runtimes; failed createBot rolls back ghost players; auto-respawned bots no longer appear dead on other clients; interaction rays are occluded by blocks; backpack UI gains same-dimension & distance checks; /botmod config set/get covers 7 previously missing options; skin filename traversal validation and concurrent-safe skin cache.

v1.3.3 — 支持 Minecraft 1.20–1.20.4 · 游戏内行为编辑器 · 智能路径平滑

共 3 个对应版本的 JAR，按你的 Minecraft 版本选择。需要 Java 17+。本次发布不含 Minecraft 1.20.5–1.21.4（需 Java 21+ 的构建目标），仅支持 1.20–1.20.4。

行为编辑器（editor.zip）——可选的离线 Blockly 编辑器：GitHub 下载，或在任意 1.3.3 版本页的 文件 → Additional files 获取。解压后用浏览器打开 editor/behavior-editor.html，用 100+ 积木编排行为，保存 .json 到 .minecraft/config/my-bot-mod/behaviors/，游戏内分配给假人即可。（v1.3.3 也新增了游戏内编辑器，HTML 编辑器完全是可选的。）

更新要点

• 多版本构建升级：工具链升级到 Gradle 9.7 + Fabric Loom 1.17.19，改用 Stonecutter 单代码库多版本构建。本版发布 1.20.1、1.20.2、1.20.4 三个 JAR，覆盖 Minecraft 1.20–1.20.4。
• 游戏内行为编辑器：分类面板、语句列表、参数表单、嵌套控制流面包屑导航；产物与 HTML 编辑器完全兼容，保存即热重载，可导出到任意文件夹（服务端校验）。
• 新输出积木：outputRaw（无前缀原始行）、outputTemplate（自定义模板，{time} {bot} {var:名} 占位符）、outputTable（自定义表头 + 逐行追加 CSV）；原有输出积木增加追加/覆盖模式。
• 行为执行界面重做：实时状态行显示队列进度（x/y）；播放列表 ▲▼ 排序、移除、一键清空；行为搜索框；每行可单独快捷执行或直接进编辑器。
• 创造飞行继承：飞行中召唤的假人同样进入飞行并悬停；状态随 preserveBotState 保存。
• 末影箱：/bot <名字> enderchest 直接绑定假人末影箱实时编辑，关闭自动保存。
• 智能路径平滑（pathfindingSmooth，默认开）：宽度感知视线法合并可直行路标点；跳跃/下落/游泳锚点与裂谷不受影响。

寻路重构

• 寻路器重写为同步一次性优化 A*（硬上限 15000 次迭代 / 25000 节点）；移除旧的 string-pulling 平滑，由宽度感知智能平滑取代。

移除的功能

• 编组与合作建造系统整体移除：/botmod group * 与 /bot <名字> build * 命令、相关界面、行为积木与配置项。
• 移除 Carpet 兼容模式（carpetModCompatibility）：可与 Carpet 同时安装，各自管理假人。
• 移除指挥棒传送的创造模式限制（allowBatonTeleportNonCreative）；清理死代码（从未实现的 onMessage 事件、无效的 configMenuKey）。

BUG 修复

• 右键面板"删除假人"按钮现在真的能用了（走新增的 /bot <名字> kill confirm，确认窗口严格校验）。
• 修复皮肤优先级反了：本地 skins/ 的 PNG 和 Base64 皮肤优先于 Mojang API，离线不再白等网络超时。
• 行为编辑器界面文案全部走语言文件（原来硬编码中文）。
• 行为脚本异常不再崩掉服务器 tick；broadcast 不再同 tick 双重执行；重复启动行为不再泄漏运行时；createBot 失败回滚假玩家（不再有幽灵玩家）；自动重生的假人不再在其他客户端躺尸；交互射线被方块遮挡；背包界面加同维度与距离校验；/botmod config set/get 补齐 7 个缺失配置项；皮肤文件名防路径穿越、缓存改并发安全。
