Wet asphalt tyre tracksShelf-Made Tycoon
When it rains, trucks should leave dark tyre tracks on the wet asphalt that fade out over a game-hour. Keep the flat-shaded look; decals or particles only, no new models.
I’ll read the approved brief and the truck, rain and asphalt code first, then wire the track effect into the existing movement and weather flow.

FAQ

Questions

What is Flockbay?
Flockbay is a free AI game maker built on Godot: a desktop app for Windows, macOS and Linux whose AI builds and play-tests a real Godot 4 project inside the full Godot editor, on free AI every day or your own Claude or ChatGPT. The project is an ordinary Godot project on your own disk, on the official engine, not a fork, and the game runs locally. Building needs an internet connection. There is no browser version.
What the AI does
Flockbay's AI, on its free hosted model or your Claude or ChatGPT in the chat, or your own agent over MCP, writes GDScript and scenes into your Godot project. It places props, builds rigged 3D models with the modeler, finds Godot plugins for you to install, and playtests the game: a headless run, stdout and parse errors, viewport capture, input events and the live scene tree. You judge the result by playing it.
Platform
Windows, macOS and Linux: the current release runs on 64-bit Windows with an Intel or AMD processor, on Macs with Apple Silicon, and as an x86_64 Linux AppImage. There is no web version, no browser editor, no browser preview, and no mobile app.
Who writes the code
Your AI does, and you can: it writes the GDScript into a real Godot 4 project, and Flockbay hosts the full Godot editor, Script editor included, beside the chat. You can open, read and change every file there, in stock Godot or in your own code editor.
Where the game runs
Output is a normal Godot project in a normal folder on local disk. Games run locally on the copy of Godot bundled with the app. No streaming, no cloud rendering, no cloud building.
Pricing
Free, AI included. Every account gets free AI each day on Flockbay's hosted model. Or build on your own AI: your Claude plan (Pro or Max) or your ChatGPT account (any plan, Free included) in the app, your own agent over MCP, or your own API key (OpenAI or Anthropic), and you pay the company that runs your model, never Flockbay. Optional plans add more hosted AI: Hobby at $20, Indie Developer at $60 and Studio at $200 a month. There is no team, per-seat, or enterprise plan. Projects and assets are private.
AI models
Free AI runs on Flockbay's hosted model, Demo in the model menu, which Flockbay picks. On your Claude plan, Flockbay runs Claude Code, and the model menu lists the models and effort levels Claude Code gives you. On your ChatGPT plan, it runs your account's models through the bundled Codex engine. On an API key, it runs any model the key reaches, and an agent over MCP uses whatever model that agent runs.
