GM2Godot

GM2Godot is a self-reported open-source tool that transpiles GameMaker Language (GML) code into Godot Script (GDScript), aiming to automate the migration of games from the GameMaker engine to Godot. The author, a solo developer, built it using Python and AI models (Codex with GPT-5 series). It supports importing GameMaker projects and converting assets and code into a Godot project structure.

The tool is described as fast, modular, and easy to use, with a focus on transpiling GML to GDScript. The author notes that it works well for simple games like top-down shooters and Pacman-style games but acknowledges challenges in handling engine differences and compatibility.

The description states that GM2Godot is a transpiler converting GameMaker games to Godot games. It imports GameMaker projects and converts assets and code into a Godot project structure. Specifically:

• It transpiles GML (GameMaker Language) to GDScript (Godot Script).
• It supports importing config files, settings, game title, icon, description, audio buses, sprites, music, sounds.
• The tool is described as fast, modular, and easy to use.

Inference The tool appears to be a utility for developers migrating from GameMaker to Godot, with a focus on code conversion and asset handling.

Not evidenced No information about the tool’s architecture, UI, or whether it is a CLI tool, GUI app, or plugin.

The author positions GM2Godot as an open-source tool for developers who want to migrate games from GameMaker to Godot. The evolution of its claims includes:

• Initially, the tool was meant to port assets between engines.
• It evolved into a transpiler that converts GML code to GDScript.
• The author highlights that it works with simple games like top-down shooters and Pacman-style games.

Inference The tool is positioned as a migration aid for indie developers or those maintaining legacy GameMaker projects, especially in light of the author’s own experience with GameMaker and Godot.

Not evidenced No claims about scalability, enterprise use, or support for complex or large-scale projects.

The description states that GM2Godot is intended for developers who are migrating from GameMaker to Godot. The author notes that they themselves used GameMaker for two games and later moved to Godot for a third project.

Inference The primary user base appears to be indie or hobbyist game developers who have existing GameMaker projects and want to transition them to Godot.

Not evidenced No information about the size of this target group, whether it includes professional studios, or if there is a defined customer persona beyond the author’s own experience.

The description states that GM2Godot is an open-source tool. There is no mention of any commercial model, pricing, or monetization strategy.

Inference The tool is likely free to use and distributed under an open-source license, with no direct revenue model described.

Not evidenced No evidence of paid features, subscriptions, or monetization methods beyond the open-source nature.

The author reports that GM2Godot was built using:

• Python
• Codex with GPT-5 series models

Key technical details include:

• The tool supports fast, modular conversion.
• It handles assets and code transpilation from GameMaker to Godot.
• CI/CD pipelines are part of the development process.
• Unit tests are used for new features.
• Multithreading is used to handle thousands of files.

Inference The tool is built with automation in mind, using AI-assisted development and structured testing practices.

Not evidenced No information about performance benchmarks, scalability, or deployment architecture.

The author states that:

• They self-published two games on Steam using GameMaker (2022 and 2024).
• They are now working on a third project in Godot.
• The tool works for simple games like top-down shooters and Pacman-style games.

Inference The tool is in an early stage, with limited real-world usage beyond the author’s own projects.

Not evidenced No evidence of adoption by other developers, user feedback, or community engagement. No metrics on usage, downloads, or project success rates.

The description does not mention any direct competitors or similar tools in the market for GameMaker to Godot migration.

Inference The tool may be one of few, if not the only, open-source solutions for this specific task, given the niche nature of the problem.

Not evidenced No information about existing tools, platforms, or services that perform similar functions.

• Solo developer project: The tool is built by a single person (Infiland Dragojevic), which may limit scalability and long-term maintenance.
• No traction or adoption: There is no evidence of usage beyond the author’s own projects.
• AI dependency: Reliance on Codex and GPT-5 models may pose risks related to availability, cost, and accuracy.
• Limited scope: The tool works for simple games but may not support complex or large-scale projects.
• Open-source nature: While open-source is a plus, it does not indicate any commercial viability or monetization strategy.
