BlueMap Offline Player Markers (Forge)

Adds markers where players last logged off to BlueMap.

Closeup	Faraway

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 on v1.4+ (as of v3.0) (do open an issue if I missed some OG features)

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 to 1.21.11)
• 1.5.X (minor=5) will refer to java 26 (minecraft 26.1 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
But be aware that since the mod launched I got smaller and smaller time frames to work on it so things like updating Java17-v1.3 and Java26-v1.5 is taking forever to get out (due to the sheer amount of test and code updating done to support multiversioning).

Java17 is no longer supported in future updates and once a new modding version is out on Java26 (26.1+) I may drop Java21 (1.20-1.21.11) - Do feel free to help me with PR if you are not scared of spaghetti API code (that should not need rewrite)

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 -> 1.21.11

• 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
