ReUI Ecosystem (4z0t)

ReUI is the most comprehensive, feature-rich, and visually polished UI mod suite for FAF by modder 4z0t. It fundamentally overhauls the interface: factory queues, hotkeys, scoreboards, ACU actions, and economy displays.

There is one massive catch. 4z0t writes brilliant code, but when it comes to project organization and maintenance - he is an absolute trainwreck. Some updates go to GitHub, some drop into his Discord, some update in the client, and some sit on Boosty.

Ecosystem Architecture: How It Works

1. Core Framework (ReUI) - mandatory technical foundation for every mod in the lineup.
2. Standalone Modules - mods requiring only the core library (ReUI.Score, ReUI Reclaim, ReUI.Hotbuild, etc.). Can be enabled selectively.
3. Dock Container (ReUI.ActionsPanel) - effectively a second library. Does nothing on its own until you install specific sub-modules (ACU upgrades, missile launch, etc.).

Section Modules:

• ReUI - Core library + Some QoL functions
• ReUI.ActionsPanel - empty dock container (requires extensions: ACU, missiles, templates)
• ReUI.Score - compact, modern player scoreboard
• ReUI.Reclaim - mass clustering and total reclaim counter
• 📦ReUI.Hotbuild - advanced custom cycle-bind builder
• ReUI.Construction - revamped construction panel
• ReUI.Economy - scalable resource tracker

Core ReUI & Built-in QoL (ReUIUIQoL)

The ReUI core is not just a backend library - it includes the built-in ReUIUIQoL module, which handles auto-hiding clutter (making mods like Auto Hide UI completely obsolete):

ReUIUIQoL Settings:

Start game with menu panel closed
Auto-collapses the top system menu at match start.

Start game with multifunction panel closed
Auto-collapses the orders panel at match start.

Movable menu panel
Allows freely dragging the top menu bar anywhere on screen.

Settings: F10 → ReUI Options → ReUI.UI.QoL

🧩 ReUI.ActionsPanel (+ Extensions)

Modular dock panel for quick access to orders, abilities, and upgrades.

Dependencies: ReUI
Settings: F10 → ReUI Options → Actions Panel

Available Extensions:

1. ACU Enhancements

Displays available ACU/SACU upgrade icons directly on the actions panel.

• Queue enhancements (gun, shield, RAS, engineering) in one click without opening the enhancement menu

2. ReUI.MissilePanel

Quick missile weapon management dock.

• Displays ready missile counts for TMLs and strategic silos (Nukes)
• Quick Fire: selecting a TML or Nuke via the panel automatically primes the attack order on cursor

Grouping Missile Silos:
Group silos for simultaneous volleys:

• Select a TML on map (or panel) → hold RMB on another TML in the panel → choose group/ungroup from the context menu.

Settings: F10 → ReUI Options → Missile Panel

3. Advanced Key Actions

Contextual smart-bind module. Assigns multiple actions to a single key based on current unit selection.

How it works:

• ACU/SACU selected → activates Overcharge (OC)
• Factory selected → toggles Repeat Queue
• Transport selected → enters load mode
  (All on a single keybind)

Settings: F10 → Key Bindings → ReUI.Actions

4. Factory Templates

Quick access to factory build queues directly from the actions panel.

• Places saved build templates onto ActionsPanel buttons

(GIF below shows how to create and save a template)

🧩 ReUI.Score

Modern player scoreboard with instant one-click unit and resource transfers.

Settings:

• F10 → ReUI Options → ReUI.Score : Fonts / Colors
• F10 → ReUI Options → ReUI.Score : General

Quick Transfers (Main Feature)

Transferring Units (click faction icon):

• LMB on ally faction icon - instantly transfers all selected units

Transferring Resources (click Mass or Energy columns):

• LMB - send 25% of your current pool
• Shift + LMB - send 50%
• Ctrl + LMB - dump 100% of resources to ally
• RMB - request mass/energy from this ally

General Settings

Fonts & Colors

Custom ARGB sliders and fonts for player names (Name font/Name color), timers, game speed, unit cap, and observer panel.

🧩 ReUI.Reclaim

Reclaim overlay with label clustering, total mass counter, and display optimization.

Key Features:

• Auto-display: reclaim labels appear automatically when selecting the reclaim order
  
• Batching: groups nearby rocks and wrecks into clusters, eliminating visual clutter
• Total Reclaim Counter: displays total mass available in current view
  

Settings & Performance Optimization

Settings: F10 → ReUI Options → ReUI.Reclaim

🧩 ReUI.Hotbuild

Custom build-bind creator with template support and hybrid chains (structures + unit orders).

Why Vanilla Hotbuild Falls Short

In standard game, players are locked to rigid presets: you cannot bind generators, radars, and factories onto a single key E.

ReUI.Hotbuild removes all limits: build custom sequences combining any structures, units, and templates.

How It Works:

1. Build the Sequence in the Editor
Assemble the sequence:
F10 → ReUI Options → ReUI.Hotbuild

Enter bind name in top bar and click Save (top-left dropdown lets you edit existing binds).

Execution order runs strictly top to bottom: highest row = 1st keypress, next row = 2nd keypress, etc.

2. Automatic Registration
Registers as a new hotkey under:
F10 → Key Bindings → ReUI.Hotbuild

3. Assign Hotkey
Bind the registered action to any key (e.g. E).

Core Features:

1. Hybrid Binds (Engineer + Factory on One Key)
Mix buildings and unit production orders on the same key:

• Engineer / ACU selected → E cycles generators, radars, factories
• Factory selected → E queues units (e.g. air scout at air factory, Brick at T3 land factory)

2. Templates in Cycle
Insert entire saved templates into the bind cycle (e.g. instead of a naked T3 mex, drop a fully capped T3 mex template).

Chain Editor: F10 → ReUI Options → Hotbuild
Key Bindings: F10 → Key Bindings → ReUI.Hotbuild

🧩 ReUI.Construction (+ Templates)

Revamped lower construction panel: drag-and-drop queues and template preview.

Construction Panel (ReUI.Construction)

Drag-and-Drop Factory Queue
No need to cancel queues to rush an emergency scout or AA. Hold LMB on a queued unit icon and drag it forward to build next:

Selective Transport & Carrier Cargo Unloading
Selecting a transport shows loaded units and counts. Click to choose who drops first (see GIF below). (Vanilla has unloading, but this adds visible unit counts).

Settings: F10 → ReUI Options → ReUI.Construction

Template Tool (ReUI.Construction.Templates)

Template creation is already native to FAF, so this module is valued strictly for its interactive hover preview:

• Base Templates: hovering over a template displays a minimap preview showing exact building footprints and spacing
• Factory Templates: shows a unit grid with exact unit counts
  

Settings: F10 → ReUI Options → ReUI.Construction.Templates

• Templates name length - slider (1 to 10 characters)
• Preview build templates - toggle base template preview
• Preview factory templates - toggle factory queue template preview

🧩 ReUI.Economy (+ EconomyMiddle)

Resource bar scaling and screen centering.

• Scaling (Scale): scales the mass and energy bar (essential for 2K/4K displays)
• Style & EconomyMiddle addon:
  • default style keeps the bar in top-left
  • Installing the EconomyMiddle addon adds a style that moves the resource bar strictly to the top center of the screen
    

Settings: F10 → ReUI Options → ReUI.Economy
