EOrigins API

EOrigins API is a reusable Forge 1.20.1 addon for Origins and Apoli. It adds bounded entity queries, persistent target storage, movement utilities, projectile ownership tools and other building blocks that origin and datapack authors can use directly from JSON.

It does not replace Origins or Apoli, and it does not add a playable origin by itself. It extends Apoli's existing action and condition registries so custom origins can use additional eorigins_api:* factories alongside normal origins:* features.

Diagnostics

Operators can inspect the API without installing a separate profiling addon:

/eapi status
/eapi debug queries
/eapi debug storage <player>
/eapi debug reset

Query diagnostics report accumulated calls, spatial candidates, selected results, result-limit hits, average time and maximum time for API-owned queries. Storage diagnostics show named target, position and entity-set slots without printing raw UUIDs.

The debug commands require permission level 2.

Examples

Capture nearby living entities into a persistent set:

{
  "type": "eorigins_api:collect_entities",
  "slot": "example:targets",
  "mode": "replace",
  "radius": 16.0,
  "limit": 32,
  "shape": "sphere",
  "sort": "nearest",
  "include_self": false,
  "bientity_condition": {
    "type": "origins:target_condition",
    "condition": {
      "type": "origins:living"
    }
  }
}

Act on the currently loaded members later:

{
  "type": "eorigins_api:action_on_entity_set",
  "slot": "example:targets",
  "limit": 32,
  "same_dimension": true,
  "require_alive": true,
  "bientity_action": {
    "type": "eorigins_api:pull_target_toward",
    "strength": 1.25,
    "stop_distance": 1.5,
    "include_vertical": true,
    "set_velocity": true
  }
}

Use your own namespace for slot identifiers to prevent collisions with other datapacks.
