ALIS is an open-source Unreal Engine 5 survival project set in a post-apocalyptic
real-world city. The public repository exposes the full modular C++ plugin architecture,
data-driven workflows, and gameplay systems under active development.
The project is built around modular plugins with clear ownership boundaries,
contract-first integration, and JSON-driven definitions. Each gameplay system
lives in its own plugin with its own README and architecture docs.
Current public systems:
- Inventory - server-authoritative with equip, use, drop, weight, volume, depth stacking
- Vitals - server-side metabolism tick, threshold states, condition regen/drain
- Dialogue - universal data-driven dialogue for NPCs, objects, terminals
- Mind - inner-voice thought guidance system
- Interaction - player interaction via trace and prompt
- Object Capabilities - composable components: lockable, loot container, pickup
- GAS - Gameplay Ability System integration layer
- Character, Motion, Settings, Loading (6-phase pipeline)
The repo is public and designed for architecture study, code review, and contributions.
