RedFoxExpand
by Kyeitk
RedFoxExpand lets resource pack authors change container GUIs through JSON files, without the mod itself being edited or recompiled for each change.
What it does
Authors describe an interface in a resource pack using Schema v2, v3 or v3.1 JSON files, with PNG textures next to them. A definition can append, replace or disable an existing screen, and definitions are ordered by priority so that one pack can override another. Screens are matched by key or text, by menu type, or by mod namespace with all, any or not rules.
The mod is client-side only, so only the player needs it installed and servers run without it. It is published for Fabric and Forge across the game versions 1.7.10 – 26.2, with files for 1.8.9 and 26.2. The source code is public, and the project is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, so it is not open source.
Key features
JSON-defined GUI changes
Screens and slots are altered through schema-based JSON, using the same texture and layout data a pack already ships.
Definition priority
Append, replace and disable actions are resolved by priority, so conflicting packs can be ordered predictably.
Texture, layout and animation
Packs can set textures, layout, animation, colors, visibility and style themes, and PNG alpha is respected.
Targeted slot control
GUI slots can be addressed directly, letting a pack reposition or restyle single inventory elements.
Planned HUD and widget support
The next stage targets diagnostics, an inspector, semantic slots and HUD widgets, built on the same core.
