Bringing Old Game Editors Back to the BrowserAugust 16, 2026 · 4 min readLi JinDora SSR developerBefore Dora SSR, I built a game engine project called Dorothy. It was Dora's predecessor, and many resource formats and creation ideas can be traced back to it. Dorothy included editors for character hierarchy and animation, physics shapes and joints, and particle parameters. The original tools were themselves written with the engine's own interfaces. That gave them immediate runtime feedback—but also tied their data, UI, and execution environment closely to an old engine structure.
