Custom Mob Spawns
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.
Custom Mob Spawn
Simple configurable mob spawning.
Fork of Custom Spawns that support 1.20 and beyond, credits to b3spectacled for making the mod in the first place.
How to install (Client and Server)
Simply slide the mod inside your "mods" folder along side Cloth Config and you are good to go.
The mod's config files are located in "config/custom-mob-spawn.json", alternatively if you installed the mod on a client and don't want to go to the config files, you can install Mod Menu and go from there.
