pHD ▪ An intelligent manager for HolographicDisplays

⚠️ pHD replaces HolographicDisplays:LineTrackerManager with a modified version, in order to manage individual hologram visibility.


HolographicDisplays generates the holograms that are managed by pHD.

HolographicDisplays requires ProtocolLib to modify hologram visibility.

Soft dependencies

If Citizens is enabled, pHD ensures that player NPCs do not trigger the hologram visibility logic.

If LuckPerms is enabled, pHD uses LuckPerms data to populate tab-completion for the permission option.

If Multiverse-Core or MultiWorld is enabled, pHD loads after, and processes relevant world manager events, to ensure that all holograms in all worlds are registered.
