Apothecary Boss-Tracker

Real-Time Blue Protocol: Star Resonance -- Boss HUD.

What is this?

It's a game overlay {developed for the Apothecary Guild} that displays real-time boss HP information across all channels for each world-boss, helping you quickly find and target the bosses that are closest to death for easier and faster kills.

Think of it as a "boss scanner" that helps you optimize your channel hopping.

Features

  • Floating Overlay: Sits ontop of your game-window.
  • Hotkey Control: Show/Hide, click-through.
  • Live Tracking: Real-time HP updates for the channels of the boss you're hunting.
  • Smart Sorting: EDT (estimated death-time), or HP fallback.
  • Customizable: Adjustable opacity, text scaling, size, position, hunting target {boss}.
  • Lightweight: Minimal dependencies, low overhead.

Quickstart Guide

First-Time Setup

There is none. Download, extract somewhere convenient, and run BossTracker -- that's it.

Window & Tray Icon

  • The program opens as a floating window (always on top) and shows a system tray icon.
  • Tray icon colors:
    • Red = disconnected / idle
    • Green = streaming data
  • Double-click tray icon to show/hide the main window.
  • Right-click tray icon for context menu and help.

Selecting a Boss

  1. Click on the dropdown (combobox) at the top of the window.
  2. A list of bosses will appear:
    • Red entries = no known alive sightings
    • Green entries = one or more channels thought to be alive
  3. Counters and colors update in real-time.

Customization

When the window is in focus, additional options appear at the bottom:

  • Transparency slider: Right = more opaque, Left = more transparent.
  • Text-Scale: Increases size of HP bars and health text.
  • Hotkey rebinding: Click on Show/Hide or Click-through hotkeys to reassign them.

Click-Through Mode

Use this once you've positioned the overlay how you want it:

  1. Move the window into place.
  2. Select the boss you're hunting.
  3. Engage Click-through via hotkey.

This prevents accidental interaction with the overlay while gaming.

Reading the Display

  • EDT (Estimated Death Time) and DPS displayed for a channel = strong indicator the boss is alive and data is valid.
  • Sorting is based on EDT, with a fallback of HP.
  • Boss reset time shown in upper-right corner.
