[1.13.2] Anvil repair materials

[GreenbackCafe]

I'm in the process of rewriting my code after finding a better tutorial, and I was wondering how to use an item as a repair material for tools/armor. Before, I would just call the variable directly from my ItemList (which would have things like "public static Item copper_ingot;"), and the ItemList would be used to statically initialise the items. Now that I've learned that's not a good idea, I switched to Cadiboo's method, but I no longer have a variable to reference as an Item for things like this. Is there another way to do this? 

 

I'd also appreciate any general suggestions on how to improve my code.

Use the `@ObjectHolder` annotation on I believe a static final field initialised to null (if you have a look at some mods on GitHub you will see it).

This did not work for me. The items still showed up as normal, but the anvil is still not accepting the repair item even though I called the fields. GitHub updated

This:

Will always pass null to here:

Because those fields aren't set until after this is done:

How do you correctly use those fields after onRegisterItems has completed?
