The Original Paper plugin source code by @TechnicJelle, Its Fabric port source code by @syorito-hatsuki.
Neither TechnicJelle nor syorito-hatsuki have any responsability to take concerning this mod or its code or its issues. So please do not report issues comming from my fork to their github/curseforge/modrinth pages.

Fork Informations

This fork includes:

  • All the features of TechnicJelle's plugin (as of right now, v3.0) (do tell me if I missed some features, old or new)

What has been added on top:

  • v1.4.1 (&& 1.3.2 if I decide to ever release it)
    • /fakeOfflineMarker <name> [<pos>] [<uuid>] to create fake offline player markers
    • /deleteOfflineMarker <name> to delete a choosen marker
    • hideBannedPlayers and removeBannedPlayerMarkers, unlike TechnicJelle's mod you can chose if you want to hide or delete the markers from banned players (or none of the above if both parameters are false) if put to delete, a server restart is advised
    • advancedMode this parameter enables the deleteOfflineMarker command server restart required
  • v1.4.2
    • hideHiddenPlayerMarkers that lets you configure if you want hidden players to have a offline marker created when they log out

New naming convention:

  • 1.3.X (minor=3) refers to java 17 (minecraft 1.18 to 1.20.4)
  • 1.4.X (minor=4) refers to java 21 (minecraft 1.20.5 and up)

Small platform specific updates will now be under: 1.major.minor.platform-specific

  • Each new version will have the content of the past minor version plus new content (see above for fork contents)

Compatibility

The current mod requires BlueMap (and KFF for 1.20.4 and lower).
Please refer to the version changelog of the file your are using as to which versions to choose from.

If you are interested in what is planned for this fork, see my Github TODO List

Current Compatibility:

Forge 1.18.2 -> 1.21.4

  • Bluemap 3.12 -> 5.5 (or up)
  • Kotlin For Forge 3.9.1 -> 5.9.0

NeoForge 1.20.2 -> 1.21+ (and 26+)

  • Bluemap 3.12 -> 5.5 (or up)

My special thanks to:

syorito-hatsuki and @TechnicJelle for providing their source code, as without them I would not have been able to port the mod from syorito-hatsuki's fabric version to Forge and NeoForge
