Color 2 Prefab

• Designed and developed a custom Unity Editor tool to convert images into playable levels.
• Built a color-to-prefab mapping system that lets designers generate levels in a single click.
• Created an extensible architecture so teams can define their own palettes and generation rules.
• Optimized the workflow to drastically reduce time spent recreating level concepts inside Unity.
• Published and maintained the tool on the Unity Asset Store.

Color 2 Prefab is a Unity Editor tool that converts pixel art or layout images into fully populated scenes. Each color in the source image is mapped to a prefab, allowing designers to build or tweak levels in an image editor and then generate the corresponding geometry and objects inside Unity in seconds.

I originally created this tool while working on Save the Purple Frog. I needed to sketch level layouts quickly and then reproduce them in Unity, but the manual process was slow and repetitive. With Color 2 Prefab, I could paint a level as an image and instantly turn it into a playable scene, dramatically accelerating iteration.

• Reads image data (PNGs/JPGs) and maps each pixel color to a corresponding prefab.
• Lets users define custom color-prefab dictionaries through an Editor UI.
• Generates complete levels directly in the Unity Editor with a single button press.
• Supports regenerating sections, enabling quick iteration on specific areas of a level.
• Includes options to control spawn height, offset, parent objects, and layer/organization rules.
• Designed to be project-agnostic: works for platformers, puzzle games, top-down layouts, and more.

• Implemented as a custom Unity Editor Window using IMGUI.
• Uses Texture2D APIs to read pixel data and translate it into world/grid positions.
• Spawns prefabs with configurable scaling and rotation rules.
• Supports extensibility: additional rules or mappings can be registered via scriptable assets or code.
• Focused on clear UX for designers, with tooltips, warnings, and simple setup flows.
