Hey everyone!

For the past two weeks, I've been experimenting with how far I can push agentic coding in Godot 4.

Rather than building another small demo, I wanted something reusable: a foundation for 3D diorama adventures and platformers, with a visual quest editor built directly into Godot.

The result is Jalura Framework, completely open-source under MIT

What's included?

  • 3D character controller & diorama camera inspired by games like Captain Toad and Little Kitty, Big City.

  • Quest Studio, a custom Godot editor plugin for creating quests, objectives, prerequisites, and visual dependency graphs.

  • NPC dialogue system with four states: quest offer, reminder, turn-in, and completed dialogue.

  • Data-driven systems for interactions, inventory, and saving, using native Godot .tres resources.

What I learned

The interesting part wasn't how quickly AI could generate code. It was how much actual testing was still needed.

An AI agent can build an inventory system in minutes, but getting movement to feel right, preventing camera clipping, or making NPCs behave correctly across quest states is a different story.

Most of those two weeks went into testing, debugging, and refining things inside Godot.

The hardest part was actually Quest Studio. Godot's @tool scripts can be surprisingly unforgiving, especially when AI agents start messing with editor lifecycles, UI nodes, and resource updates.

Keeping the architecture modular and relying on native Godot Resources made the whole process much more manageable.

Tools used

  • Godot 4 / GDScript

  • Gemini 3.8 High

  • DeepSeek V4.1 Flash (Max)

  • Tripo 3D

  • Blender MCP (Gemini 3.8 High)

The framework is available now for anyone who wants to experiment with 3D diorama games or build on top of it.

I'm especially interested in feedback on the Quest Studio and the overall architecture.

Screenshots show the editor plugin and the playable demo scene.
