Concept

by dannytaylor

Concept is a Fabric mod for 1.21.10 that scrambles how boats, water, vines and some entities behave, mostly as a chaotic challenge build.

What it does

Boats move at altered speeds: they go fast on land and slow on water, which reverses the usual handling. Water is also replaced in some places, and a contact effect applies a potion when a player touches it. Vines cause a light-headed effect on contact, and a piss effect was added as a status effect.

Entities that carry a particular effect have their cosine and sine motion swapped, so their movement looks wrong on purpose. The mod was assembled from ideas the author's audience suggested during a challenge stream, which explains the mix of unrelated changes. It requires Fabric API, and it runs on client and server, so the server and every player need it. Source code is public, and the code is open source under the GNU Lesser General Public License v3.0 or later. Files are published for Fabric only, for 1.21.10, with the latest build 1.0+fabric-1.21.10 released on 2025-11-29.

Key features

  1. Reversed boat speed

    Boats travel quickly over land and slowly over water, so the usual movement feels inverted.

  2. Water replacement

    Some water is replaced by other content, changing how lakes and rivers look and behave.

  3. Vine contact effect

    Touching a vine applies a light-headed effect that alters the player's view while it lasts.

  4. Swapped entity motion

    Entities under a certain effect have their cosine and sine movement swapped, producing erratic paths.

This was made for a challenge stream out of suggested ideas (that's why it's so chaotic)
