[1.18.1] Loot modifier when the player has a capability

[Twingemios]

I want to add a feature to my mod where any blocks a player breaks are auto-smelted whenever they have a certain capability value.

Is there any good resources on creating new LootItemConditions that check a player's capabilities. Or if LootModifiers aren't the best way to go about this what is the best?

you can get the Entity (with cast the Player) via LootContext#getParamOrNull and LootContextParams.THIS_ENTITY

Alright I've got that. Now do you know of any sources that may be able to help with the other parts of this? The docs don't cover any custom LootItemConditions or types.

You mean like the autosmelting functionality?

After a lot of research I have written what I believe to be all of the necessary code. I'm currently struggling to get it run however. I can't figure out how to make the .json file for the auto_smelt. I just need it so that the player is sent to test function in the LootItemCondition I have created. That way I can check their capability

{
  "condition": "minecraft:entity_properties",
  "predicate": {
        "type": "minecraft:player"
  }
}

i would recommend you to use DataGenerator to create the json files automatically,
the Forge example also use data generation, take a look at this
