About

Description

A library and quality-of-life mod for Forge 1.20.1. It gives you a HUD editor with windows like windows 7, a cosmetic armor system by example, and an API so Rudolph's mods can use.

HUD editor

Open the editor with its keybind (default "h") and arrange your HUD however you like.

  • Drag HUDs with the right mouse button, or nudge them with the arrow keys (hold Shift for bigger steps).
  • Every HUD is a window with a border and an X button. Closing one shrinks it away.
  • Closed HUDs wait in the "Choose removed huds" panel (Tab). Drag them back out with the right mouse button.
  • HUDs slide along each other's edges instead of getting stuck, so you can place them flush.
  • Optional grid snapping and center guide lines.
  • Per-HUD option: show it while playing, or only while the editor is open.
  • Positions and visibility are saved per HUD.

Cosmetic armor

  • Visual-only armor slots: your real armor keeps its stats, but you show whatever compatible armor you want.
  • The armor HUD shows only your cosmetic armor. It stays empty if you have no cosmetic pieces, even when you wear real armor.
  • The inventory screen includes your real armor and off-hand slots, and its inventory window can be closed.
  • Cosmetic armor is visible on you and on other players, and works in multiplayer.
  • Optional: drop cosmetic items on death.

Config

A configuration screen with ordinary Minecraft buttons, so resource packs can restyle it. You can change:

  • Window, border, panel and scrollbar colors
  • Editor background color, opacity and blur
  • Animation speeds
  • Every editor key
  • Whether window borders are shown, and whether the HUD key opens the inventory screen directly

Debug mode (off by default)

Use any block face as a HUD, or duplicate any HUD. Handy for testing layouts.
