About this project
What does Poly+ (PolyPlus) add?
PolyPlus
PolyPlus is the companion mod for OneClient. It adds OneClient's online features to the game.
Host a world
Pick a world from the main menu, or use the button that replaces "Open to LAN", and your friends can join without any port forwarding (they need PolyPlus too).
- Choose the game mode and whether cheats are allowed
- Invite single friends or a whole group
- Share your resource pack with everyone who joins using
/polyplus sharepack - Works with Simple Voice Chat
- Regular LAN hosting is still there
Friends and chat
Open the Social menu with Shift+P.
- Add friends by username
- Direct messages and group chats
- Block players

Cosmetics
Capes, wings, hats, glasses, gloves, boots, auras, back and shoulder items, plus pets on modern versions and emotes from an emote wheel.

- Choose whose cosmetics you see for each type: everyone, friends only, just yourself or nobody
- A badge on nametags and in the tab list shows who else uses PolyPlus

Main menu
A new title screen with Quickplay for your last servers, a 3D preview of your player, an account switcher and featured servers. Every part can be hidden, or you can switch back to the vanilla menu entirely.

- A warning when your memory allocation is hurting performance
- A Windows sensitivity converter in the controls screen (1.8.9)
