Gamemode Detector

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 1.20–1.20.1Newest
Minecraft 1.19–1.19.4

⬇ Download for 1.20–1.20.1 ⬇ Download for 1.19–1.19.4

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.

Have you ever joined a SMP and wondered if the owner is switching in/out of creative mode?
Introducing Gamemode Detector

This is a client mode having one purpose: to notify you when other people switch their gamemode. Pretty simple, right?

If you are ever scared that the mod will spam you every time you join a big server (cuz of the NPCs), starting from v1.1, you can directly disable/enable the mod in game using ModMenu

If you have any suggestion, you can create an issue or pull a request on my github repo and I'll hopefully implement them.

Have fun!
