Accurate Projectile Trajectory Preview
by siakinnik
Accurate Projectile Trajectory Preview shows, on the client, where an arrow, snowball or potion is expected to land before it is thrown or shot.
What it does
The mod draws the expected flight path of a projectile while the player holds the item, so the landing point is visible before launch. Its trajectory prediction is meant to be closer to vanilla projectile behavior than the original Projectile Trajectory Preview, and it is published as a fork of maDU59's work.
Random spread offsets in the game's projectile physics mean the real impact point can land a little away from the line the preview draws. The mod models that spread using the velocity, the distance from the start and a maximum spread factor. Target highlighting colors the trajectory to show how likely a hit on the target is.
The fork changes both the simulation logic and the multiplayer behavior. It drops the server handshake check and the networking validation, so the preview stays available on the client without a server-side requirement. Because it is client-side only, servers run without it and players need nothing beyond the NeoForge file for 1.21.11.
Key features
Trajectory visualization
A line shows the expected path of a projectile before it is launched, for arrows, snowballs and potions.
Target highlighting
The trajectory color changes to indicate a higher likelihood of hitting the target.
Spread-aware prediction
The preview accounts for random spread offsets in projectile physics, so the drawn path can match real impacts more closely.
No multiplayer restrictions
The preview does not depend on a server handshake, which removes the multiplayer limits of the original implementation.

Who it’s for: Players who shoot arrows, throw snowballs or potions and want to see the landing point first. It is built for NeoForge 1.21.11 and runs on the client only.
How it compares
Projectile Trajectory Preview [PTP] is the original project this mod forks; it is open source under the MIT License and loads on Fabric, NeoForge and Quilt for 1.21 – 26.3, with the client required and the server optional. Targettier is client-side only, loads on Fabric and NeoForge for 1.21 – 1.21.11, and is not open source under the MIT License.
