The mod uses a single global table named storage to keep persistent data for all systems.
This is required because Factorio scenario scripts have limited options for storing global
state.
storage has two main sections:
storage.SM_Store– global mod settings and shared state.storage.PData– per-player data indexed byplayer.index.
Each system stores its values in these tables rather than creating additional globals.
The structure is created during on_init by STORAGE_CreateGlobal() and
STORAGE_MakePlayerStorage() in storage.lua.
When adding new fields, try to group them logically under these tables. For example,
storage.SM_Store.votes holds active vote-banish information and
storage.PData[player.index].active tracks whether a player was active this tick.
Keeping related values together helps avoid conflicts and makes saved data easier to
inspect.
