Flow
by The Cogs
Flow is a Fabric client mod that adds configurable ease in-out animations when inventory screens open and close.
What it does
Flow animates the movement of inventory screens when they open and close, using an ease in-out curve. Players can choose the easing type, set a background tint and blur, and pick the direction a screen slides in from. The mod includes built-in fixes for compatibility with several other interface mods, and it is expected to work alongside many others without extra setup.
The mod requires Fabric API and MRU to run. It is client-side only, so servers do not need it and players can join without installing it. Files target Fabric for game versions 1.20 – 1.21.1, with the latest file, 2.2.0+1.21, built for 1.21.1 and dated 2024-11-16. The code is not open source; the mod is released under All rights reserved, and public source code, an issue tracker and a wiki are linked from the project page.
Key features
Ease in-out transitions
Opening and closing inventory screens use a configurable ease in-out animation instead of an instant switch.
Slide directions
Screens can enter from the left, the right and other sides, giving the transitions more varied motion.
Blur and tint options
Background blur and tint during the animation can each be adjusted to suit the player's preference.
Easing selection
The curve that drives the motion can be changed, so the pace of each transition can be tuned.
