Chyma
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
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.
- CHJMA: Acronym for "CustomHud JourneyMap Addon" (pronounced 'chime-uh')
- Chyma: The above, but easier to read and pronounce
Yes the logo is comic sans, fight me
