How do you drop something or give the player something when he kills the ender dragon?

[river nimbus]

The title of this post is what I want, My datapack version is 1.20.3-1.20.4.

I tried many methods, like editing the loot table of the dragon in data/minecraft/loot_tables/entities/ender_dragon.json.

used, advancement to check if the player killed an ender dragon and give him a loot table, and even tried to use the give command to give directly to the player, but the main problem is whenever I kill the ender dragon of the end or the /summon ender_dragon the advancement don't get triggered nor it drops the loot as per data/minecraft/loot_tables/entities/ender_dragon.json

Might be a bug

ask me if u want any part of my code

also i deleted the loot_tables/entities/ender_dragon.json but i wanted to drop a custom item

[tiny junco]

{
  "criteria": {
    "requirement": {
      "trigger": "minecraft:player_killed_entity",
      "conditions": {
        "entity": {
          "type": "minecraft:ender_dragon"
        }
      }
    }
  },
  "rewards": {
    "loot": [
      "namespace:loot_table"
    ]
  }
}

this is an advancement

[river nimbus]

yes

[tiny junco]

namespace:loot_table will be your loot_table

[river nimbus]

i tried this

but it didnt work

[tiny junco]

?

i suppose entities have a "DeathLootTable" nbt

[river nimbus]

wait

[river nimbus]

then can i edit it directly?

like

each tick

i change "DeathLootTable" nbt of ender dragon

[tiny junco]

/summon ender_dragon ~ ~ ~ {DeathLootTable:"namespace:file"}

[tiny junco]

yes

idk about doing it every tick but

i think you can just do it once

and you should be fine

[river nimbus]

k

[river nimbus]

thk

[tiny junco]

you can use that command to modify data of existing ender dragon

i suppose u alr know that

[river nimbus]

yes

@tiny junco
for testing should I kill the ender dragon from /summon cmd or the ender dragon of the original end to test the drops?

[tiny junco]

why would it matter which one

and unless you've been to the end then the ender dragon of the end doesn't exist

[tiny junco]

so if you've already summoned a dragon use this command to modify the existing dragon's nbt

[tiny junco]

if you wish to kill and summon another use this

wont make a difference really

[river nimbus]

@tiny junco not working

i tried on both

[tiny junco]

whats your loot_table

[river nimbus]

{
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "minecraft:item",
                    "name": "minecraft:stone",
                    "functions": [
                        {
                            "function": "minecraft:set_count",
                            "count": 3,
                            "conditions": [
                                {
                                    "condition": "minecraft:random_chance",
                                    "chance": 0.35
                                }
                            ]
                        }
                    ]
                }
            ]
