Surprising Loot

Surprising Loot

Surprising Loot can let you create datapacks to define unexpected encounters to adventurers!
When a player first opens a container tied to a specific loot table, there is a configurable chance to spawn entities nearby, making treasure hunts far more thrilling or insteresting.
Supports both vanilla and modded loot chests, and is compatible with Lootr.

An example datapack is included in
data/surprisingloot/loot_events/example.json:

{
  "loot_table": "minecraft:chests/jungle_temple",
  "check_range": 3,
  "chance": 1,
  "spawn_times": 3,
  "entity_pool": [
    {
      "weight": 2,
      "entity_type": "minecraft:zombie",
      "nbt": "{CustomName:'\"Gift\"',CustomNameVisible:1b,Health:2.0f,Attributes:[{Name:\"generic.max_health\",Base:50.0}]}"
    },
    {
      "weight": 1,
      "glowing": true,
      "entity_type": "minecraft:bat"
    }
  ]
}
