Live-Building AI-Driven PCG with Godot, C#, and Gemini | Sharmishtha Sen | GameDev Day 2026

Creating vibrant, immersive game worlds shouldn’t require endless manual modeling or lead to repetitive designs. By leveraging the C# workflow improvements in Godot 4 with JetBrains Rider, developers can turn language models into procedural co-creators while keeping their own artistic vision intact. This 30-minute session builds a live procedural content generation (PCG) pipeline that turns human-friendly prompts into playable environments. It shows how to run a local open-source AI agent with Ollama alongside cloud endpoints to generate typed JSON configuration schemas that feed directly into statically typed C# models. You’ll see how to expose AI parameters and scene references in the Godot Inspector, so you can prompt, adjust seeds, and rebuild environments in real time, with immediate player execution and debugging feedback through Rider. Whether you’re crafting 3D heightmap terrain with FastNoiseLite or designing procedural 2D dungeons with TileMaps and dual-grid algorithms, the session shows how to connect algorithmic generation to handcrafted locations, keeping a solid foundation for tutorial areas, named landmarks, and designed gameplay moments.
