small Recipe System change

[CodeBlack]

Hey there guys.

I am currently working with the Recipe System made by Diablo-dk and i was wondering if it is possible to change it, so it only Fuses the Items when in the Inventory of a Special Unit/ Building.
I want to make sth like a crafting station.
Unfortunately the System isnt made with Triggers, so i have no idea how to do so :/
Can somebody help?

That recipe system fires when a unit picks up an item. It should use orders.

RecipeSys should be what you're looking for. There is GUI example in the thread.

at top there's additional function function Recipe_Conditions takes nothing returns boolean where you can add raw code of units that can merge items. I made 2 fields, you can add more or use just one type.
like: return id == 'Hpal' or return id == 'Hpal' or id == 'Hamg' or id == 'Hmkg'

at top there's additional function function Recipe_Conditions takes nothing returns boolean where you can add raw code of units that can merge items. I made 2 fields, you can add more or use just one type.
like: return id == 'Hpal' or return id == 'Hpal' or id == 'Hamg' or id == 'Hmkg'
