About Sit
There are two versions at present, you can search for the Sit (Fabric) easily.
The current creation makes sitting become possible. You can use slabs and stairs as a chair.
You will start your activity by right-clicking the top side of a right side up slab or stair blocks with an empty hand. Then, you can on it.
You can do the same on half beds.
To exit, you can strike the key that you utilize to leave a minecart. SHIFT is the default key.
As normal, slabs or stairs from other mods will be supported. Nevertheless, you can contact the author if any do not work.
There’s a single configuration option. It is block_reach_distance. It finds the number of the blocks that a player can be away from a slab/stair to still be capable of sitting on.
Sit is a cosmetic mod. It requires Minecraft Forge. Additionally, you should install the release on the client and server so it can run in Multiplayer.
