[1.7.10]Generic Item Creation while in-game

[UberAffe]

I am working on a mod that allows users to design weapons armor and possibly machines while in game and use them in the world. Does forge support registering new items while in game and if so what library/class would I make use of to do so?

[Ernio]

It doesn't (directly).

Registration must always happen in init phases. System simply won't allow you do that nicely.

 

What you can do:

Base everything about item on its NBT.

You can make NBTItem that would pull its model, colors, properties, damage, attributes directly from NBT.

For armour (vanilla) you would only have to make 4 pieces. For rest - one class.

Lemme tell you - good design allows damn lot wiht NBT (that's what I do).

I hate you ernio. You answer to fast.

I appreciate the fast response http://minecraftforge.net/forum/Smileys/default/grin.gif

 

I don't want to set a limit on the number of items created and it sounds like this will allow that so that's good.

 

I'm not terribly familiar with NBT, do you know of a resource I could look at to learn a bit about how it works/syntax of it?

Basically - Item is description of what an item is.

Then there is ItemStack that holds data.

It has Item, meta, stackSize and NBT.

When stack is saved it saves all those fields (note that NBT can be null).

 

You can use NBT to store any kind of additional data.

If you look into Item.class you will notice that many methods have 2 version - one is not argumented, one ships ItemStack - that allows you to read properties from stack.nbtTag (there is getter).

The main thing you should know is that you will limit the amount of items that ur users create anyway, because you are setting restrictions. Your machine will have 10 different features? That will make 2^10 different types of machines.

Your item can be any type of tool and 5 different miningspeeds? That will make 4*5 items.

@Failender

Technically yes, but the nature of the material they will use to create these items will be giving them an absurd number of possibilities.

I explain the mod pretty well in this post:

@Enio

Thanks for the link and the explanation, I'll see how far that can get me

@Draco18s

I may be misunderstanding the code but it seems like it is almost like a factory class, it randomly chooses from a set of registered items and acts as the interface for that item.

 

Which will be useful for handling the interactions once the item is created, but I still need to read through information Ernio gave me for the in-game item creation part.

My factory is random, but it doesn't have to be. The important part is the Item class translating from NBT to effect.
