[Unsolved] invotory

how would i make a invotory bigger than 6 slots?

One unit can't carry more then 6 items. But, you can create a stash (like in TBR), or multiboard inventory (as made HappyTauren in his trigger system). There is many ways.

A: You wouldnt. You would make multiple 6 slots of inventory.

First of all: It's called an inventory.
Second of all: Check out the Spells section here.

i just need something to have 8-10 slots for holding materials for the crafting part of my game

There are such things that allow you to 'swap' inventory pages. They got an 'item' in the 6th inventory slot which shows the 2nd 'page' with items.

I'm not entirely sure how they made it, but they can be found in the link I posted previously.
