Good day,

I am working on a battery item for my mod and it uses data values for the amounts of energy it is currently holding, but the biggest problem comes when I put 2 batteries into the anvil. The damage value adds the second damage value and plus bit more.

Example:

If I put a battery with 1200 energy into the first slot and into the second slot the same battery with the same amount of energy, the outcome isn't 2400 as I would expect, but it is 3600. That means that it "generated" additional power.

Is there a way to make it, so the outcome is 2400 or even better to completely disable the anvil recipe?

Anyone?

Use NBT data instead of damage values.  The anvil works in a very specific way where two items of the same ID will repair each other in this fashion.  Just so you know, it isn't free.  It does cost the player some experience.

 

(And the majority of the bonus is actually from crafting two damaged items together: 10%  Using an anvil and an experience level upgrades that to a whopping 12%)

Ok, thanks! I'll definitely try that!

You'll probably have to write a custom item renderer to get the "damage bar" back, though.

 

On the other hand, simply HAVING nbt data might disqualify the item from being repaired.....and now that I've said that....

 

On moment.

 

Ah, there's also setNoRepair();

setNoRepair(); is for the 2 tools in crafting table repair.

I've also tried getIsRepairable(ItemStack i1, ItemStack i2), but that doesn't seem to work.

Darn.

Is there a way to "extend" tile entities that are already in the game? For example the anvil tile entity.

Sure you can.  Doing it won't replace the vanilla version though.
