Solved Make Custom Item Not Stack

Im creating a custom item using the "Compass"
It has a Custom Name and everything. But I wish to not let it stack at all.

I got some code working so u cant stack them in ur inventory and chest etc. But what about picking up the item. And on a further note, When you drop a certain amount of item of the same type doesnt bukkit/minecraft automatically Group them together? how can this be prevented?

 

If it has a custom name it won't stack.

 

They Do Stack
The Custom item is Created Through the Workbench. You can create multiple of them. I coded so you cant Stack them "in the inventory" but when i press "Q" (to drop the item) then pick it up. Itll stack ontop of my Other Custom Item.

As for the 2nd problem. If I drop 2 Custom Items (using Q) at the same location. They get Grouped Together.

 

Oh, ok. Try setMaxStackSize.

 

How is that used?

Figured it out, Thanks
