I cannot figure out how to override vanilla loot tables, I've been at this for hours, and I can't find anything online. Just very outdated tutorials.
I added custom crops and seeds to my mod, now I need those seeds to drop from the in-world grass.

The loot tables for my custom blocks are in data.modId.loot_tables.blocks and they work just fine.

Now, when I try to override the grass to drop an item of my choosing, say, coal, I do this:

1) Make  grass.json

2) Fill it:

{
  "type": "minecraft:block",
  "pools": [
    {
      "rolls": 1,
      "entries": [
        {
          "type": "minecraft:alternatives",
          "children": [
            {
              "type": "minecraft:item",
              "conditions": [
                {
                  "condition": "minecraft:match_tool",
                  "predicate": {
                    "item": "minecraft:shears"
                  }
                }
              ],
              "name": "minecraft:grass"
            },
            {
              "type": "minecraft:item",
              "conditions": [
                {
                  "condition": "minecraft:random_chance",
                  "chance": 0.125
                }
              ],
              "functions": [
                {
                  "function": "minecraft:apply_bonus",
                  "enchantment": "minecraft:fortune",
                  "formula": "minecraft:uniform_bonus_count",
                  "parameters": {
                    "bonusMultiplier": 2
                  }
                },
                {
                  "function": "minecraft:explosion_decay"
                }
              ],
              "name": "minecraft:coal"
            }
          ]
        }
      ]
    }
  ]
}

 3) Place it in my project in

data.minecraft.loot_tables.blocks

 

 

 

When I test it in game, grass still drops wheat seeds and not coal. Why?

Put your custom loot table in data.minecraft.loot_tables.blocks. Yes, you need to create the minecraft folder in your src/main/resources/data directory. It should get overridden proving the file is named the same as the vanilla loot table.

I already have. It doesn't work. Read point 4 please

How about just adding a new loot table with pools only with your mod seeds items instead of overriding the entire grass loot table? Overriding would block others potential opportunity to make their own seeds that drop from vanilla grass.

How would I go about doing that?
