JourneyMap in All the Mods 10

JourneyMap is a real-time map that fills in your world as you explore. You can view it in game as a minimap or in a full-screen view, or open it in a web browser.^[1]

Client and server

JourneyMap is a client+server mod, but the map itself lives on the client. Currently the server side is only for controlling JourneyMap features, and no mapping is done on the server at this time. JourneyMap needs to be on the client if anything is to be displayed.^[1]

The server side is optional in both directions. You can join a server that does not have JourneyMap, and players without JourneyMap can join servers that do.^[1]

In this pack

This pack ships JourneyMap 1.21.1-6.0.6, using the NeoForge build (journeymap-neoforge-1.21.1-6.0.6.jar). It has been in the pack since version 2.25 or earlier.^[2]

Unverified The sources here do not show any quests for JourneyMap or a place for it on the ATM Star path, so check the pack's quest book for that.

The mod's developers keep guides and tutorials on their own documentation site, and they offer support on the JourneyMap Discord server. Server admins running Bukkit or Paper can find extra setup details there too.^[1]

Good news: JourneyMap doesn't ask you to craft anything to get going. It maps your world in real time as you explore, so load in and start walking around.^[1]

Your first steps

1. Explore. JourneyMap maps your Minecraft world as you move, and you can view the result in-game as a minimap or full-screen map.^[1]
2. Check the hot keys. The mod has an option that shows you the hot keys you can use with the map, so look there before hunting through the vanilla controls.^[3]
3. Try the web map. The same map can be opened in a web browser, which is handy if you want a second screen for navigation.^[1]

About the web map port

The web map uses a default port, and you can set it to a value between 80 and 10000. If that port is already in use, JourneyMap tries to find an open one by increments of 10.^[3]

Good to know early

• JourneyMap has to be on the client for anything to be displayed. At the moment the server side is only for controlling JourneyMap features, and no mapping is done on the server.^[1]
• If the game runs rough, the mod's options say that turning off always-map-caves and always-map-surface improves performance.^[3]
• Lower cache and refresh delays in the advanced options can hurt performance, so leave them alone unless you have a reason to change them.^[3]

Here's the honest part first: JourneyMap isn't a machine mod. The sources describe it purely as a real-time mapping tool, and they say nothing about machines, multiblocks, power, fluids or item automation. So this section covers how the mapping itself works and which settings affect it.^[1]

Client and server roles

JourneyMap is a client+server mod for Forge, Fabric and Quilt. It maps your world in real time as you explore, and you can view that map in a web browser or in-game, either as a minimap or full-screen.^[1]

The mapping happens on your client. The server side of the mod only controls JourneyMap features from the server and does no mapping, so JourneyMap has to be installed on your client or nothing will be displayed. Clients can also join servers that don't have the mod, and clients without it can join servers that do.^[1]

Viewing the map in your browser

The web map uses a default port, and you can enter a value between 80 and 10000. If that port is already in use, JourneyMap tries to find an open one by increments of 10.^[3]

How the map is drawn

The map has several views. The auto map type rotates between day, night and cave if the matching show options are checked. There are also night-only and topography-only types. Map styles add extras such as a biome map, a topography contour map that shows elevation changes, and bathymetry, which shows the ocean floor and underwater terrain.^[3]

Cave mapping has its own controls. One option always maps the caves in your vertical chunk, even when you're on the Overworld surface. Another always maps the surface, even when you're underground. Disabling either improves performance. A threshold option sets how many blocks it takes to switch to cave mode, which stops the map flipping when you walk into a house.^[3]

AutoMap and zoomed-out tiles

AutoMap works through region tasks, and there's a delay setting between them. Lower values make AutoMap finish sooner but can hurt performance. Automapping all layers takes significantly more time and uses more disk space, so use it with caution.^[3]

When you're zoomed out, the map can use LOD (level-of-detail) tile rendering. Turning it off and saving deletes the LOD cache files from disk. There are also dialogs to invalidate the zoom LODs, either for the current dimension or for the whole world.^[3]

Caching and performance

JourneyMap caches several kinds of data so it doesn't recheck them constantly. Radar data for animals, mobs, players and villagers each has its own cache duration in milliseconds, and so does your own status data. A separate setting controls how often the map draw steps (radar entities and waypoints) are rebuilt. For all of these, lower values refresh faster but can hurt performance.^[3]

Multiplayer map separation

Two experimental options help keep maps from overwriting each other on multi-world server setups: one uses the world seed and the other uses the server IP address when saving data. Both only take effect after you rejoin the server.^[3]

Unverified The pack's own JourneyMap settings and any changed defaults could not be checked, because no config files for this mod were available. Treat the behaviour above as the mod's general behaviour, not confirmed pack values.

All the Mods 10 8.1 ships JourneyMap 1.21.1-6.0.6. The mod was first included in All the Mods 10 2.25 or earlier.^[2][4]

The pack changelogs record JourneyMap as a version bump in each release. For a long stretch, every bump moved to a newer 6.0.0 beta build. That covers releases 2.28, 2.30, 2.37, 2.40, 2.42, 2.43, 2.47 and 3.0.^{[5][6][7][8][9][10][11][12]}

The beta bumps carried on through 4.0, 4.1, 5.5, 6.0, 6.2, 6.3, 7.0 and 7.1. Each of those releases again moved JourneyMap to a newer 6.0.0 beta build.^{[13][14][15][16][17][18][19][20]}

Out of beta

In pack release 7.2, JourneyMap moved from a 6.0.0 beta build to 1.21.1-6.0.1. That is the first release in these changelogs where the new version has no beta tag.^[21]

• 7.3: 1.21.1-6.0.1 to 1.21.1-6.0.2^[22]
• 8.0: 1.21.1-6.0.2 to 1.21.1-6.0.4^[23]
• 8.1: 1.21.1-6.0.4 to 1.21.1-6.0.6^[4]

Unverified The pack changelogs only list version numbers, and no stored changelogs are available for the shipped jars. What changed inside JourneyMap in each update lives in the mod's own release notes, and the sources here do not show it, so no specific features or fixes are listed.
