Im trying to setup this inventory system with my own textures and im not sure which numbers do what, i need to know where does it get set for the placement and where is it set to say how many columns and rows there are. Im not entirely sure where to start to get the hitboxes in the right place and to make the button overlap to be in the right place, if you or anyone else could reply back and tell me where i should start that would be greatly appreciated
