FlowUI

by f1natory

FlowUI adds short, responsive animations to the interface elements players use most, while keeping vanilla behavior intact.

FabricClient-side onlyMIT LicenseOpen source1.21.11

What it does

When a container screen such as a chest, crafting table or furnace opens, it grows in with a brief scaling effect, and the background, slots, items and player model slide in as one unit. The animations are kept short and do not slow down interaction.

The mod changes only interface animation. Menus are not redesigned, gameplay mechanics are not changed, and original content behaves as before. The goal is to make Minecraft's existing visual language feel a little smoother without replacing the original design. Fabric API is required, and the code is open source under the MIT License. Files are published for Fabric only, for 1.21.11.

Issues with another mod that behaves incorrectly alongside FlowUI can be reported through the public issue tracker, and the source code is available in the public repository.

Key features

  1. Animated container screens

    Inventories, chests, crafting tables and furnaces open with a quick scale animation instead of appearing instantly.

  2. Gliding hotbar selection

    The selected-slot indicator slides between hotbar slots rather than jumping to the new position.

  3. Sliding player list

    The player list slides onto the screen when opened and slides back out when closed.

  4. Unified window motion

    Background, slots, items and the player model shift as one unified panel.
