NeverEnoughAnimation

Inventory and HUD transitions get short animations: hovering over an item draws a gray rectangle that fades in on its slot, a hovered item grows slightly larger, and a stack moved with shift-click slides to its target slot. Scrolling the hotbar animates the current item marker, and opening or closing a GUI plays a brief transition. Throwing an item out of the inventory is animated as well.

The features are configurable. Setting the animation time to 0 disables them, and the interpolation curve can be changed to suit a different feel. Compatibility with Mouse Tweaks covers scrolling, and Just Enough Items gets animated ingredient areas on its side, though the batch display of HEI is not covered. Some modded GUIs may not render correctly, and a render mode option exists for those cases.

The mod requires MixinBooter on both loaders. Just Enough Items and Mouse Tweaks are optional. NeverEnoughAnimation is client-side only, so servers run without it and players install it alone. It is published for Forge and NeoForge across three game versions, 1.7.10 – 1.21.1, and the code is under All rights reserved, so it is not open source. Public source code and an issue tracker are linked.
