Trajectory Tracker

Trajectory Tracker is a sleek, 100% purely client-side Minecraft mod that visualizes projectile trajectories, distance measurements, and exact impact points in real time.

It does not alter any gameplay mechanics: no click interception, no modified throw velocities, and zero network packets sent to the server. It is a completely passive visual helper, making it 100% compatible with any multiplayer, vanilla, or modded server!

✨ Key Features:

1. Mathematically Exact 3D Trajectory Preview:

   • Calculates flight arcs matching vanilla Minecraft physics (player velocity inheritance, gravity, air drag, and water friction).
   • Renders a clean glowing trajectory path with directional arrows in world space.

2. Surface-Oriented Impact Marker:

   • Projects a sharp bullseye landing marker onto any surface (floors, angled terrain, walls, and ceilings).
   • Accurately detects collisions with both blocks and living entities.

3. Compact Minimalist HUD:

   • Unobtrusive pill display rendered comfortably below your crosshair:
     • Distance in meters (e.g., 16.6m)
     • Flight time in seconds (e.g., 0.55s)
     • Target name (e.g., Grass Block or Spider (16 HP))

4. 100% Vanilla Server & Multiplayer Safe:

   • Does not require server installation (displayTest = IGNORE_SERVER_VERSION).
   • Works out-of-the-box on Vanilla, Paper, Spigot, Fabric, and Forge servers without triggering anti-cheat or handshake rejections.

5. One-Time Onboarding Tip:

   • Sends a friendly chat message explaining the controls the first time you hold a throwable on a world/server – exactly once per server/world, never spamming you again.

🎒 Supported Items:

• Vanilla Throwables: Snowballs, Ender Pearls, Eggs.
• Potions & Magic: Splash Potions, Lingering Potions (with authentic -20° pitch offset), Bottles o' Enchanting.
• Ranged Weapons:
  • Bow (dynamically adapts speed based on draw time / pull power).
  • Crossbow & Trident.
• Modded Item Support:
  • Automatically detects modded throwables (TACZ grenades, bombs, spears, shurikens, flasks, daggers, etc.).
  • Potion trajectory lines dynamically inherit the color of their active potion effects.
