Polysit
A polymer-based server-side sit mod for Fabric & Quilt!
Installation
Requirements:
Install Minecraft, Polymer, Polysit and your mod loader of choice. You only need to install it on the server, but there's a client-sided enhancement if one prefers.
You also have the option of using it in singleplayer or with friends over LAN.
Using
You can right-click/use any slab, stair and bed to sit on it.
There's also /sit, which allows you to sit practically anywhere, even on cacti... if you're immune to thorns.
For clients with the mod, there's also a keybind named Sit, which defaults to G.
It'll similarly let you sit anywhere, if the server is running Polysit.
Note:
Servers using other mods or plugins that happen to also include
/sitas a command, or using an older version of Polysit, may not use the same checks or be as seamless as the latest version.If the server does not support or blocks
/sit, this keybind may be unavailable and cannot be used.Unfortunately, this is unavoidable as the only method Polysit uses on the client is the
/sitcommand.
Compatibility
It is compatible with any mod that implements standard slabs, stairs and beds. It's even compatible with the scale attribute, and other scaling mods such as Pehkui.
Note:
1.20.1 and older has poorer support for Pehkui. Bugs in relation to scaling while sitting will occur. There are still mitigations for Polysit's other behaviours.
If for any reason, there's a slab, stair, bed, or any other seat-like block that doesn't work, feel free to submit a bug report.
Changes to Vanilla Logic
Polysit does try to fix bugs that were found in development, or directly caused by its functionality.
- Moving the player out of blocks when getting up.
- Forcing the player to take a smaller pose to avoid suffocating when getting off a seat.
- This applies generically to any seat, not just Polysit's.
- Forcefully sending relevant packets for bugs caused by Mojang's fixes or changes.
- Beds during the day can be right-clicked to sit on it.
All help to ensure that Polysit provides the best UX it possibly can while also maintaining vanilla-esk logic.
