Origin (Entity Condition Type)

Checks whether the player currently has a given origin, on one layer or on any layer.

Type ID: origins:origin

note

This condition comes from the Origins mod. It only passes for players, and any other entity fails it.

Fields

Field	Type	Default	Description
`origin`	Origin pattern, or an Array of them	required	The origins to look for. The condition passes if any of them matches.
`layer`	Identifier	optional	Only checks this layer. Leave it out to pass when a match is held on any layer.
`selection`	Selection	`main`	Where to look: `main` (the chosen origin), `active` (the swapped-in origin, or the chosen one when the player isn't swapped), `pool` (origins in a swap pool) or `all` (any of the three).

An origin pattern is an identifier that can use * as a wildcard in its namespace or its path. my_pack:aliens/* matches every origin whose path starts with aliens/, at any depth. Without a *, it is an ordinary identifier and must match exactly.

Examples

{
  "type": "origins:origin",
  "origin": "origins:phantom",
  "layer": "origins:origin"
}

This checks whether the player is a Phantom on the main layer.

{
  "type": "origins:origin",
  "origin": "origins:merling"
}

This checks for a Merling on any layer, including a copy layer the player picked it up on.

{
  "type": "origins:origin",
  "layer": "origins:origin",
  "origin": [
    "my_pack:base",
    "my_pack:aliens/*"
  ]
}

This matches a whole family of origins without listing them one by one.

tip

Use the list form instead of wrapping several origins:origin checks in an origins:or. It reads better, and because "inverted": true applies to the whole condition, one inverted copy of it gives you the exact complement, which is what a derived layer needs for its other branch.

Gating one power on several origins

A power can behave differently depending on which origin the player picked. Grant the power broadly, then branch inside it:

{
  "type": "apoli:action_over_time",
  "interval": 20,
  "entity_action": {
    "type": "apoli:if_else",
    "condition": { "type": "origins:origin", "origin": "origins:merling" },
    "if_action": { "type": "apoli:gain_air", "value": 4 },
    "else_action": { "type": "apoli:feed", "food": 1, "saturation": 0.5 }
  }
}

Every second, a Merling regains some air, and any other origin gets some food instead.

Notes

This reads the player's current choice. To test an origin saved earlier, use origins:stored_origin.
It works on both sides. The server reads the player's origin state and the client reads its synced copy, so it is safe in render and HUD conditions.

Checking a swap pool

selection decides which of a player's origins count. By default only their chosen origin does, so a swapped-in origin reads as absent unless you widen it:

{
  "type": "origins:origin",
  "origin": "origins:phantom",
  "selection": "active"
}

This passes while the player is actually playing as a Phantom, swapped in or not. Use pool to ask whether they could swap to it, and all to ask whether they have it at all.
