RotVitals

Floating health bars over every enemy's head in Grain Rot.

What it does

• Tracks at frame rate. The bar reads the enemy's live health every frame, so it never lags a hit, and it stays locked to the enemy while you move.
• Damage-lag ghost bar. A pale red bar drains behind the fill after a hit, so you can see exactly how much that swing took off.
• Hit punch. The bar pops the instant health drops.
• Reads at a glance. Fill ramps green → amber → red over a segmented track, framed with a drop shadow and a bone rim.
• Not a wallhack. A bar only goes up once line of sight is confirmed, and comes straight down the moment cover breaks it, so nothing shows through geometry — not even a flicker as you move past a wall. Range is capped at 18 m too, so you cannot read a room before you enter it.
• Enchanted enemies get a gold rim.
• HP numbers above the bar (42 / 118), switchable off.
• Flying drones too. Drones have no health of their own — they live and die by the character flying them — so their bar shows that character's health, which is what actually decides whether the drone goes down.

Only enemies get bars. Players, soul vessels and friendly NPCs are ignored.

Multiplayer

Purely local and visual. It reads replicated health, so it works whether you are hosting or joining, and lobby mates without the mod see nothing different.

The game only replicates an enemy's current health; its maximum is worked out on each machine separately and is not meaningful on a machine that does not own the enemy. So when you are joining someone else's game, the bar takes its maximum from the highest health it has seen that enemy at. Enemies are at full when they spawn, so this is normally exact — and it is the only approach that stays correct when the host runs a mod that changes enemy health. The one case it cannot know about is an enemy that was already damaged before you ever laid eyes on it, which will read as full until you damage it further.

Performance

Bars are pooled and each one is its own canvas, so a moving enemy costs a single position write per frame. Enemy intake is event-driven — no polling loops — and only the nearest 16 on-screen enemies are ever drawn.

Tuning

Everything is in the CFG block at the top of mod/Scripts/main.lua:

No hotkeys, no config file, no external processes, nothing written to disk.

Notes

Bar placement uses the mod's own world-to-screen maths against a camera extrapolated one frame forward, because the per-frame hook it runs from fires before the camera manager updates — without that, bars visibly swim whenever the camera moves. On startup it cross-checks its maths against the engine's own projection and only switches over if they agree, so on any build where that assumption does not hold it quietly falls back instead of misplacing bars. If bars ever appear to overshoot when you spin, set CAMERA_LEAD = 0.

Status lines land in UE4SS.log every 60 seconds.
