I want to add some slots to the inventory of the player for specific items. How can i add them to his inventory?

Do you want to create new tab like TiC or just add new slots to main inventory?

 

Both are possible.

2nd can be done via gui init event, check if it is player's inventory and then add new slots using reflection...

EDIT: If with 2nd you want to also draw additional "rectangle" somewhere - there's gui draw event (or something similar), which is fired when gui is drawn...

Okay great, thank you!!

I would recommend creating a new inventory for the extra slots you want and storing it in extendeproperties for the player.  With a little work, you can make it pretty graceful.

I happen to have a tutorial that covers this exact topic.

And it turns out, I used your tutorial the first time I did something like this.  It was well put together.

Lol, thak you great guys I would be lost without this Forum!!
