Hello everybody I am trying to create a mod with custom mob drops. I want add custom mob drops to my mod. But for some reason the mob drop overrides the custom mob drop. Can somebody explain to me on how to add a custom loot table without overriding a loot table.

{
  "type": "minecraft:entity",
  "pools": [
    {
      "rolls": 1,
      "bonus_rolls": 0,
      "entries": [
        {
          "type": "minecraft:item",
          "name": "examplemod:infected_ingot"
        }
      ],
      "conditions": [
        {
          "condition": "minecraft:random_chance_with_looting",
          "chance": 0.5,
          "looting_multiplier": 0.01
        },
        {
          "condition": "minecraft:killed_by_player"
        }
      ]
    }
  ]
}

This mod is for 1.20.1

I haven't done anything with 1.20.1 yet, but I believe what you're trying to do needs to be done via Global Loot Modifiers and writing up a file that injects into the existing vanilla loot table, because what you posted here looks like it's supposed to overwrite it. So I would say that the first thing you need to do is become familiar with that and how it works in 1.20.1 and then go from there.

 

this is a totorial for loot tables but his website dont work so use thi website
