About this Mod

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 /sit as 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 /sit command.

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.

Frequently Asked Questions

Polysit server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.

Is Polysit compatible with fabric and quilt?

Polysit officially supports fabric, quilt for Minecraft 26.2, 26.1.2, 26w14a. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Polysit – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Polysit consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
