Lua API reference¶
- Engine handlers reference
- User interface reference
- Game object reference
- Cell reference
- Built-in AI packages
- Built-in events
API packages provide functions that can be called by scripts. I.e. it is a script-to-engine interaction.
A package can be loaded with
It can not be overloaded even if there is a lua file with the same name.
The list of available packages is different for global and for local scripts.
Player scripts are local scripts that are attached to a player.
|Package||Can be used||Description|

that don’t depend on the game world.
Storage API. In particular can be used to store data
between game sessions.
Functions that are common for both global and local scripts
Functions for specific types of game objects.

openmw_aux.* are built-in libraries that are itself implemented in Lua. They can not do anything that is not possible with the basic API, they only make it more convenient.
Sources can be found in
resources/vfs/openmw_aux. In theory mods can override them, but it is not recommended.
|Built-in library||Can be used||Description|
Game time calendar
