Features

本页把 Fab 商店页 Mass Battle Crowds — 100,000+ crowd battling at 60 FPS 的核心功能清单逐条对照到 1.19.20 插件源码:每个功能组列出商店页宣称的能力、对应实现的源码位置(链接到本站 API 页)与关键类型/函数。标注 (Repo) 的条目为仓库/Demo 附带内容,不随插件 zip 发行。所有链接均可在左侧目录与各 API 页之间互跳。

This page maps every feature group from the Fab listing Mass Battle Crowds — 100,000+ crowd battling at 60 FPS onto the 1.19.20 plugin source: for each group it lists the advertised capability, the implementing source location (linked to the API pages on this site), and the key types/functions. Items marked (Repo) ship with the repository/demo download, not the plugin zip.

总体架构一句话:纯 CPU 驱动的 Mass Entity 模拟——确定性锁步、单一渲染管线、数据驱动 ECS;每个引擎帧按 6 个 SimStage 派发 14 个处理器,GPU 只做渲染插值,无 GPU 回读。

One-line architecture: a fully CPU-driven Mass Entity simulation — deterministic lockstep, a single rendering pipeline, data-driven ECS; every engine tick dispatches 14 processors across 6 SimStages, the GPU only renders interpolated results, with no GPU readback.
