Trajectories
by LiziardBoi
Trajectories shows a predicted flight path for arrows, snowballs, tridents, eggs and ender pearls before the player fires or throws.
What it does
Trajectories draws a glowing prediction arc from the held projectile and marks the point where it will land, so a player can adjust aim before shooting. The arc covers the projectile types the mod supports, including arrows, snowballs, tridents, eggs and ender pearls, and it is drawn on the player's own screen.
The prediction runs on the client alone. A vanilla server does not need the mod installed, and a player on a server without it still sees the arc on their screen. Installing it on the server as well is optional. Trajectories requires Fabric API and is published for Fabric only, for 1.21.8 – 1.21.11, with the 1.21.11 build as the latest file. It is not open source, and the code is under All rights reserved; the source is public for reading.
Key features
Landing point prediction
A marker shows where a thrown or shot projectile will come down, so the player can judge distance before firing.
Glowing trajectory arc
A smooth arc is drawn along the flight path from the player's hand to the predicted landing point.
Multiple projectile types
Arrows, snowballs, tridents, eggs and ender pearls each get a prediction, not only one kind of projectile.
Client-side display
The arc is computed and drawn on the player's own game, so it works on servers that do not run the mod.

Use cases
Aiming with ender pearls
A player can check where a pearl will land before throwing it, which reduces wasted pearls when crossing gaps.
Long-range archery
The arc shows how far an arrow drops at a given draw, helping a player take distant shots with more confidence.
Who it’s for: Players who throw or shoot projectiles often and want to see the flight path before committing. It suits both single-player worlds and multiplayer servers, since the arc is shown on the player's own screen.
