Stitch's UIFX - Interface Visual Effects
This Minecraft resource pack offers texture pack developers advanced capabilities for animating and visually designing the user interface. Instead of being limited by standard customization options, you get a comprehensive toolkit for creating dynamic UI elements directly in the vanilla version of the game.
Project development is ongoing - I'm actively working on adding new features and capabilities. Over time, the resource pack will become more functional and versatile.
Currently, support for previous game versions is in testing phase, but I plan to add it in the near future.
