[1.8.9] Merge itemstacks with different nbt


Failender

Recommended Posts

Hey everyone,

I have some data written to the nbt of every ItemFood. That works fine.

What I want is to be able to merge itemstacks, even if the nbt is different. I have an value written to the stacks nbt called "creationdate", and I would be fine merging the stack everytime the creationdates difference isnt more then 20.

Is there a way to do that?

Basically:

 

Nope!

 

Once a stack has NBT, even if identical, vanilla won't merge the stacks.  You're going to need to hack deep into the ItemStack class and find where it happens.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Well I did some research.

Im gonna bet ten bucks its this

public static boolean areItemStackTagsEqual(ItemStack stackA, ItemStack stackB)
    {
        return stackA == null && stackB == null ? true : (stackA != null && stackB != null ? (stackA.stackTagCompound == null && stackB.stackTagCompound != null ? false : stackA.stackTagCompound == null || stackA.stackTagCompound.equals(stackB.stackTagCompound)) : false);
    }

 

So. If you say stackA.compound=stackB.compound you should be able to merge them no problem.

But if you do that you could also create your own routine that checks every item inside a player inventory, compare the tagCompounds, and if they are "nearly equal" set the slot of the first stack to null and increment the second one stacksize.

Maybe ill do some research tomorrow
