What it does
During various in-game events such as:
- Crafting
- Weather changes
- Nearby mobs
- Sleeping
- Day/Night cycle changes
- Low health
- Low hunger
- Drowing
- Biome Discovery
- While in a Fight
- When Eating
- Random Events
…the avatar will display cute messages on your desktop.
For example, when you go to sleep in Minecraft, the 3D mascot will cheerfully say “Good night!”.
Usage Warning
Do not use this mod on public or competitive servers.
The avatar can say things like “Heyyy!! There’s a creeper behind you!!” which might be considered cheating on some servers.
Use this mod only in singleplayer or private multiplayer worlds with friends.
Technical Note
If the mod doesn’t work:
- Ensure port 32145 is open in your firewall.
- Make sure TCP and UDP traffic is properly forwarded.
The mod runs a local server on your local IP to communicate securely with MateEngine.
Additional Info
MateEngine itself is written in C# using the Unity Engine, and it is open-source and free.
(Just in case any CurseForge staff gets worried about “advertising,” don’t worry — it’s a free project.)
