rbx_reflector

Generates the reflection database delivered as part of rbx_dom_lua and rbx_reflection_database.

Requirements

  • Roblox Studio

Usage

rbx_reflector generate [--patches <PATCHES>] [OUTPUTS]

Example

rbx_reflector generate --patches patches rbx_reflection_database/database.msgpack rbx_dom_lua/src/database.json

How's it work?

  1. Locate Roblox Studio installation
  2. Generate API dump via RobloxStudioBeta -FullAPI <output>
    • The dump is written to a temporary file which we immediately read back.
    • At this point, we have a lot of information like a list of all instances and their properties, including types!
  3. Generate a derived reflection database by merging the JSON API dump with artisanal heuristics defined in patches.
  4. Execute Roblox Studio to get information accessible to Lua
    1. Generate a place file with one copy of every instance in it. It has no properties defined.
    2. Generate a plugin file from plugin.lua.
    3. Install our plugin into Studio's Plugins folder
    4. Start an HTTP server to receive messages from the plugin
    5. Start Roblox Studio, opening the generated place
    6. The plugin indicates over HTTP that Studio has opened successfully.
    7. The place is automatically saved on Windows or requires you to press crtl+s to save.
  5. Output the requested reflection databases in msgpack or JSON.
