HelmetHUD

Helmet HUD — Ostranauts

Adds a green monochrome suit readout drawn inside the visor while wearing a

powered pressure or EVA helmet. The HUD shows negative statuses and anything

you're actively training. Different helmets have different HUDs to accommodate

the life support readouts on the EVA helmet. Oh! and Pressure suit helmets now

require batteries to be more logical inside the game system. Make sure that Power

light is on, and pay attention for blinking amber battery lights.

Companion to Character Sidebar, which shows the same character data in a

full panel outside of EVA. Either works alone; they compose if you run both.

Install

This mod is two parts, a plugin and a native data pack, and both install

themselves. The one manual step is enabling the data pack in the game's MODS

menu, which only the game itself is allowed to do.

• Click Install Mod Manager (r2modman). BepInEx and the

plugin are set up automatically.

• Launch the game once. The plugin copies its data pack into

Ostranauts_Data/Mods/ on startup and logs that it did.

• From the main menu open MODS, enable Helmet HUD, and restart.

Skip the enable step and the visor readout still works, but the helmet has no

battery holder, no redrawn gauge panel and no glow; the log says exactly what is

missing.

Build

Needs OSTRANAUTS_PATH set and the Character Sidebar repo checked out

alongside this one:

C:\Claude\Ostranauts Mods\

Ostranauts Status Sidebar\ ` rather than

copied — one source of truth, two fully independent DLLs, no runtime dependency

in either direction.

Config

BepInEx/config/com.ostranauts.helmethud.cfg. Editable with the BepInEx

Configuration Manager (F1) if you have it installed, otherwise edit the file and

relaunch:

• Behaviour — Enabled, OnPressureSuits, RequireBatteries (the survival

mechanic), CellHours (how long a set of cells lasts; 0 = never run down),

CellsRequired, StockOldHelmets (fit cells to helmets that predate the mod)

• Display — BlinkCritical, ReferenceHeight
• Placement — RectX/Y/W/H (fractions of the helmet frame), EdgeInset

(how far inside the rim the text sits), GaugeSocketX/Top/Pitch/Size (where

the four gauge lamps sit, as fractions of the panel art — only worth touching

if you redraw that art)

• Paging — MaxRowsEVA (6; EVA bars fill the rim), MaxRowsPressureSuit

(18; only two gauge lamps down low), PageSeconds
