✨ Quantum Hitbox Features

  • Real-time RGBA Customization – Use intuitive sliders to pick any color and transparency level. Watch the changes happen instantly in the world as you move the bars!
  • Smooth Chroma (RGB) Mode – Enable dynamic color cycling with adjustable speed for a vibrant, animated hitbox experience.
  • Multiple Render Modes – Choose between a solid Fill, a sleek Outline, or Both to match your preferred visual style.
  • Advanced Visibility Filters – Fine-tune what you see: toggle hitboxes for all entities, only the one you're looking at (crosshair), or even invisible entities.
  • Self-Hitbox Hiding – Intelligently hides your own hitbox in first-person view to keep your screen clear while maintaining full visibility of others.
  • Native & Professional UI – A clean, intuitive configuration menu that integrates seamlessly via Mod Menu & Cloth Config.
  • Persistent Config – Your settings are automatically saved to a JSON file and reloaded every time you launch the game.
