The current inventory system is pretty minimalistic, showing the tools that players have on them but not allowing them to equip anything. For the core game of SOMA, this is sufficient, as the player never has more than one or tools on them at any given time, and tool interaction is context-based rather than manual. But people who make custom content might wish they had a more powerful inventory system at their disposal.
This mod is a utility library for people who wish to make their mods with an inventory system more reminiscent of that of Amnesia: The Dark Descent. In addition to giving a dedicated screen to the player for them to view and equip their carried tools, it also boasts a journal system as well, allowing the player to receive all kinds of extra content they can view at their leisure.
This mod also comes with a short demo map that includes some of the common ways content creators might implement such an inventory system. Feel free to crack open the script file for the map to see how it all works.
To download the mod, go to
Steam Workshop or
ModDB to pick it up. I've also written up an
article on the wiki, detailing its use more thoroughly.
