Onion (Beta)

Stop guessing what changed in your sprites.

Git is great for code, but terrible for game assets. When you change a sprite in GameMaker, Git just tells you binary file changed or shows you lines of unreadable JSON.

Onion is a standalone tool that lets you visually compare your Current Work against your Git History.

✨ Key Features

• Visual Diff Slider: Drag the purple handle to see exactly what changed between your last commit (Blue) and your current save (Red).
• Collision Mask Overlay: Instantly spot accidental hitbox changes before they break your game.
• Origin Point Check: Visualize the pivot point to ensure your animations align perfectly.
• Cloud Snapshots: Need to show a bug to your team? Click "Share" to generate a public link to your diff that works in any browser.
• Zero Config: Just point it at your project folder.

🎮 How to Use

1. Launch Onion.
2. Click "Open Project".
3. ⚠️ IMPORTANT: Select the ROOT folder of your project (the folder that contains the project.yyp file).
4. Onion will automatically detect modified sprites.
5. Click a file in the sidebar to inspect the changes.

📋 Requirements

• A GameMaker Studio 2 project.
• Git must be initialized in your project folder (git init).
• Windows 10 or 11.
