Item Inventory Issue


theoneandonly2004

Recommended Posts

Hi everyone

 

So i have started to try adding some interfaces/inventories to my items and I have hit an issue trying to apply it to my item.

The item is an egg launcher that I want the player to be able toshoot eggs for guaranteed hatching if the invenory has an egg in it.

 

However there is a problem, as when I open the inventory and place an item in a slot it duplicates it by adding it to the slot and keeping the item in my selected item  and when left clicking to take the item from the slot the items simply disappear. Any advice?

(if it helps I am following VSWEs tutorial series for 1.6 and trying to bring it over for 1.7)
