Placeholders

SomaHider both provides placeholders and reads them. Both need PlaceholderAPI. The expansion registers itself when the plugin enables and PlaceholderAPI is present.

Placeholder	Returns
%somahider_hidden%	true when the player stands in a running zone, false otherwise.
%somahider_zone%	The name of the zone the player stands in, or an empty string.
%somahider_zones%	How many zones are running.
%somahider_active_<id>%	true when the zone with that id is running.

Use them in a scoreboard or a tab list to tell players that they are currently hidden.

Setting	Resolved on	Notes
disguise.name.value	The hidden player	The result becomes their false name, cut at 16 characters.
disguise.skin	The hidden player	The result is looked up as a pool, an entry key or a username.
disguise.name.prefix	The hidden player, per viewer	Accepts relational placeholders.
disguise.name.suffix	The hidden player, per viewer	Accepts relational placeholders.
reveal[].placeholder	Depends on the rule type	See letting some players recognise each other.
reveal[].equals	Globally	Values written %...% are resolved without a player.

A placeholder that resolves to nothing falls back to a random entry from the default pool, rather than showing an empty name or no skin.

A relational placeholder (%rel_...%) is resolved for a pair of players rather than one, so its result can differ per viewer. SomaHider uses them in two places: the name prefix and suffix, and the relational reveal rule type.

They let you show the same hidden player differently to each person looking, for instance colouring the prefix by whether the viewer is an ally or an enemy.

Which relational placeholders exist depends on the expansions you have installed, not on SomaHider.
