I want to make a recipe which is unfortunately kind of complex, and I'm not sure how to, or if there is a way to implement it.

 

Here's the items it uses:

souls:soulbook { EntityTag: { id: string }, ContainedEssence: byte }
souls:essence { EntityTag: { id: string } }

 

The recipe should be shapeless and take the soulbook and one essence. The recipe should only work if the soulbook.EntityTag.id equals the essence.EntityTag.id, and it should produce a soulbook with its ContainedEssence increased by 1.

To make this work I would need some kind of custom recipe. I would have to override the method that checks if items are valid in a recipe, to check for these items, and then override the result as well.

 

Is this even possible? Should I look into adding a GUI for my soulbook item?

You need a custom IRecipe implementation and add the recipe with GameRegistry.addRecipe(new IRecipeImp(...))

Thank you very much! This was exactly what I was looking for.

 

Don't mean to be a bother, but in your opinion, what would be the best way to check if an ItemStack is an item from my mod? Would it be stack.getItem() == myModItem?

Specifically from your mod(1)? Or a specific Item from your mod(2)?

1. I would take the registry name and get the domain (modid) and compare it to my modid.
2. Then yes that would be the best way to check.

It was number 2. Thanks again!
