I am making a datapack that uses copper as a fuel, however part of that means that I need to be able to test an item when it is on the ground to see if it is one of the 37 copper items.
I have already been able to make a #tags list that I have called #copper, which works as intended.
The problem is, I have found no way of matching an entity against the tag. I was sent towards predicates, however I was unable to get it to accept multiple items or matched NBT to tags.
Here is the predicate I created using an online generator, but while the predicate appears in-game, it always returns false.
{ "condition": "minecraft:entity_properties", "entity": "this", "predicate": { "nbt": "{Item:{id:\"minecraft:copper_ingot\"}}" } }, { "condition": "minecraft:entity_properties", "entity": "this", "predicate": { "nbt": "{Item:{id:\"minecraft:copper_block\"}}" } }, { "condition": "minecraft:entity_properties", "entity": "this", "predicate": { "nbt": "{Item:{id:\"minecraft:raw_copper\"}}" } }
]As an additional problem, I know I will also need to check a list a return a number based on what item I find. ie, "copper_ingot" returns 1, "copper_block" returns 9.
For this problem I have no idea where to even begin.
