Giving players more inventory slots?

how it is possible to increase quantity of slots in stock of the player?

 

Not possibly in a sense of actual inventory slots

 

and it is possible to make a box with non-standard quantity of slots?

 

Its possible to spawn something a below the players feet that is opened like the thing i just made the skingen it spawned a small stash below the ground and had the player open it and when it closes it gets deleted i have seen a backpacks plugin that saves the data but my simple plugin didnt need that. Thats the only way i know of

 

There is a plugin, but better wait a bit til it is fixed...
Backpacks for Rust | Oxide

May I ask what you are using this function for?

 

Skin generator | Oxide

 

Ahhh yes, saw this some hours before already, looks nice, I am waiting impatient for the finished version
