OverviewGuide

Overview

Critical Health FX is intentionally focused. It handles the low-health presentation loop and keeps that loop readable through strong visuals, escalating audio, and optional overlays or tier effects.

That makes it a useful companion to almost any combat or survival stack because it sharpens danger without trying to replace your actual damage systems.

Critical Health FX purpose banner

Purpose

Make danger obvious before the player drops

Critical Health FX is for servers that want low health to feel sharp, readable, and urgent.

The plugin owns the visual and audio warning loop around low health. Red vignette, heartbeat pacing, blackout, darkness, frost, particles, and potion effects can all be staged so danger ramps up clearly instead of appearing as one sudden wall.

That keeps the system useful in both competitive and survival-heavy worlds because the player can feel the warning before they are already dead.

Overview

  • Per-player red vignette through the Paper WorldBorder overlay.
  • Heartbeat pacing that rises as health falls.
  • Optional blackout, darkness, frost, particle, and potion layers by tier.

First Boot

Lock down the global threshold first, then shape the tiers

The clean rollout is to get the trigger threshold and base vignette feeling right before you pile on blackout, frost, and extra effects.

Everything important lives in one public config, which keeps the plugin easy to stage. Start with the main critical threshold, make sure the red vignette feels right, then move into heartbeat and tier tuning.

YAML
critical_threshold_hp: 10.0
warning_blocks: 24
warning_time: 12
tiers:
  - max_hp: 10.0
    heartbeat_interval_ticks: 28
  - max_hp: 2.0
    blackout: true

From there, the admin flow is simple: /chfx gui for live editing, /chfx test for forcing the effect onto yourself, and /chfx preset when you want a fast baseline before deeper tuning.

First boot

  • The vignette triggers at the right health band.
  • Heartbeat and overlays already feel readable without overdoing it.
  • The GUI and presets work as a real admin surface, not only a demo.

Standout Features

The standout feature is how cleanly the whole warning curve can be tuned

This is not a single overlay effect. It is a staged low-health experience with presets, tiers, and separate visual or audio layers.

The plugin already supports MCWAR, subtle, hardcore, and off presets, but the real strength is in the tier system. Each health band can control border intensity, heartbeat behavior, overlays, particles, and potion effects in a way that still feels organized.

That gives the plugin a surprisingly wide range. One server can keep things subtle. Another can push a much harsher survival or combat tone from the same codebase.

What makes the plugin flexible

  • The warning curve can be tuned in steps instead of one flat threshold.
  • Audio, visual, and effect layers do not all have to behave the same way.
  • Preset flow makes fast rollout easier for busy admins.

Showcase

Show the warning ramp, not only the final blackout

Critical Health FX makes sense when players can see how the danger escalates from manageable to severe.

A strong gallery should show a mid-health warning state, a near-death state, and one admin or preset surface that proves the tuning workflow is real.

That makes the plugin feel like a polished gameplay layer rather than a one-note screen effect.

Gallery

  • The warning ramp is readable at more than one health band.
  • The final low-health state feels dramatic without being confusing.
  • Admins can tune the system without fighting the plugin.
