Adds a CustomHud variable for whether the minimap is currently shown on the hud. Free Minecraft Java mod for 1.21, 1.21.1.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.1Newest
Minecraft 1.20.4

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Chyma

Chyma for 1.21.1 requires CustomHud v4 and JourneyMap API v2 (found in Journeymap beta 6.0 and up).

Specifically, it requires customhud >=4.0.0- and journeymap >=1.21-6.0.0-

Chyma adds the boolean variables jm and jm_minimap to CustomHud. Their value is whether the ingame minimap (not fullscreen map) is currently displayed on your hud.
