Module:GameData

From Melvor Idle

The GameData module is the source of all game data which many other Lua modules rely upon. This module deals with the initial loading of the game data structure, and then enables other modules to access this both via a library of functions (preferred) and in its raw format.

To generate game data, do the following:

  1. Navigate to https://melvoridle.com within your preferred web browser
  2. Select any character, the character that is chosen has no impact but you may consider creating a new one as a precaution - the below code is designed to execute without affecting the character, although this is not guaranteed
  3. Ensure mods are disabled such that the generated data excludes any modded content. If disabling mods, the game should be reloaded first before trying to generate game data
  4. Open the browser console/developer mode (usually by hitting the F12 key for most browsers)
  5. Within the browser console, enter the following code then hit enter. If successful, the game data should appear within the console
  6. Copy the game data & update Module:GameData/data and Module:GameData/data2 accordingly
