[Version 4.0] Advancements

Advancements can be used as a condition for mobs properties.

Advancements Done

• advancements_done: An array of advancement objects
  • An advancement object
    • advancements: a list of advancements to be completed.
    • player_mode: Which player should be targeted to check if the advancements are done?
      • "nearest": When a mob spawns the advancements are checked only for the nearest player
      • "any": When a mob spawns the advancements are checked for any player in a 128 blocks radius

Advancement Objects in advancements_done work as an OR condition, only one of the advancement objects must be fulfilled.
Advancments in advancements instead work as an AND condition. All the advancements in the list must be fulfilled.

This example makes Skeletons get Resistance II when the player has defeated the Ender Dragon.

{
    "mob_id": "minecraft:skeleton",
    "potion_effects": [
        {
            "id": "minecraft:resistance",
            "amplifier": 1,
            "ambient": true
        }
    ],
    "conditions": {
        "advancements_done": [
            {
                "advancements": [ "minecraft:end/kill_dragon" ],
                "player_mode": "any"
            }
        ]
    }
}
