Free Unreal Engine 5.8 Project: Mass ECS AI Examples with State Tree and Smart Objects (JiRath)

Overview

JiRath shares MassAIExample, an Unreal Engine project primarily used to experiment with Mass, the engine's ECS framework, with each example in its own map. The open simulation example has agents gather resources to build houses, using smart objects to query resources, State Tree for AI logic and subsystems to bridge Mass and the game world.

Other examples cover Niagara visualization of about 50k entities with three LODs using bone vertex animation and billboards, nav mesh pathing, a save and load approach, wander AI, a spatial hash grid for fast queries, vertex animation characters and a bullet hell demo. The project targets engine version 5.8, with tags for older versions, and is a free MIT-licensed download from GitHub.
