I built OpenClaw plugins for the three major game engines. The AI agent controls the editor directly through native APIs: creating objects, modifying scenes, simulating input, running play mode.

Instead of copy-pasting code from ChatGPT, you tell the agent "place 3 enemy spawners near the bridge" and it actually does it in the editor.

- Unity Plugin (~100 tools): GameObject/Component manipulation, Play mode, input simulation - Godot Plugin (30 tools): Scene/node management, resources, editor control - Unreal Plugin (40+ tools): Actors, components, blueprints, level management

How it works: - Install via each engine's package manager (UPM, AssetLib, Marketplace) - Plugin runs an HTTP server inside the editor - OpenClaw connects and exposes editor operations as agent tools - Works in Editor mode too — no need to enter Play mode

All Apache 2.0. Solo dev.

Creator here. I built these over ~2 weeks each as a solo dev.

The key insight: instead of generating code for you to paste, the agent directly manipulates the editor through HTTP polling. This means it can:

- Create/modify/delete objects in the scene - Simulate keyboard and mouse input during play mode - Take screenshots and inspect the scene tree - Work in Editor mode without entering Play

Unity has ~100 tools, Godot 30, Unreal 40+. All Apache 2.0.

The plugins also work with game dev AI personas from https://clawsouls.ai/souls (gamedev-mentor, game-designer, etc.)

Happy to answer questions about the architecture or specific use cases.
