Purpose

Standalone MelonLoader mod for Data Center (Waseku) that overlays the hex color code of each CableSpinner and Rack directly in-world, so you can identify cable and rack colors at a glance without opening any menu.

Rewritten from the former root HexLabelMod for the FrikaModdingFramework workflow, now running fully standalone.

Requirements

Dependency	Notes
MelonLoader	With generated IL2CPP assemblies

This mod runs standalone and does not require FMF runtime APIs.

Installation

1. Drop FMF.HexLabelMod.dll into your Mods/ folder.
2. Launch the game — the config file is created automatically on first run at:

UserData/hexposition.cfg

Configuration

Edit UserData/hexposition.cfg to adjust label positioning and font sizes. The file is auto-generated with defaults on first launch and regenerated if any keys are missing.

# Hex Label Position Config
# File: UserData/hexposition.cfg
# Edit values, then restart game.

# Spinner (UI text near cable spool)
spinner_offset_x=0
spinner_offset_y=-6
spinner_font_min=1.8
spinner_font_max=6.2
spinner_font_scale=0.24

# Rack (world-space text at rack back-right-bottom)
rack_offset_right=-0.03
rack_offset_back=0.06
rack_offset_down=-0.02
rack_font_size=42
rack_character_size=0.05
rack_scale=1

Config Keys

Key	Type	Default	Description
spinner_offset_x	float	0	Horizontal offset relative to the source label
spinner_offset_y	float	-6	Vertical offset relative to the source label
spinner_font_min	float	1.8	Minimum auto-size font size (TMPro)
spinner_font_max	float	6.2	Maximum auto-size font size (TMPro)
spinner_font_scale	float	0.24	Scale factor applied to the source label's font size
rack_offset_right	float	-0.03	World-space offset along rack's right axis
rack_offset_back	float	0.06	World-space offset along rack's back axis
rack_offset_down	float	-0.02	World-space offset along rack's down axis
rack_font_size	int	42	Font size for the world-space TextMesh label
rack_character_size	float	0.05	Character size for the world-space TextMesh label
rack_scale	float	1	Uniform world-space scale of the rack label object

Live Reload (restricted)

Pressing Ctrl+F1 toggles live config reload (6-second interval), allowing you to tune label positions without restarting the game. This feature is restricted to a specific Steam account and will silently do nothing for all other users.

Build

dotnet build .\mods\FMF.Mod.HexLabelMod\FMF.HexLabelMod.csproj

Output lands in the standard MelonLoader Mods/ folder as configured in the .csproj.

How It Works

1. Startup — The mod defers full initialization until MelonLoader's Latest.log confirms the Steam runtime is ready (SteamID or Steam marker detected).
2. Spinner labels — Every CableSpinner gets a cloned TextMeshProUGUI label injected into its UI hierarchy, displaying the resolved hex code in white. Color is read from rgbColor, then from the _BaseColor/_Color material property as fallback.
3. Rack labels — Every Rack gets a world-space TextMesh label positioned at its back-right-bottom corner, facing away from the rack front.
4. Scan loop — Active spinners and racks are re-checked every 1.5 seconds to catch newly spawned objects.
5. Harmony patch — CableSpinner.Start is patched to inject the label immediately on spawn, before the first scan cycle runs.

Notes

• Original gameplay behavior is unaffected.
• This mod runs from mods/FMF.Mod.HexLabelMod and no longer from the repository root.
• The config file is fully rewritten if any expected keys are missing (for example, after an update adds new keys).
• FMF assembly presence is no longer required as a startup gate.
