Projectile Preview
by Sabby
Projectile Preview shows the predicted flight path of throwable items on the client before the player releases them, from snowballs and ender pearls to potions.
What it does
On the client, Projectile Preview draws the trajectory a thrown item would follow while the player holds the throw, so the landing point is visible before the throw. It covers throwable items such as snowballs, ender pearls and potions, and the preview is calculated with a physics-based simulation rather than a fixed arc.
The mod is client-side only, so a player can use it on a single-player world or on a multiplayer server without the server installing anything. Projectile Preview is a Fabric mod and needs Fabric Loader. It is released under the MIT License, and the code is open source, with its source code and issue tracker publicly linked. Files cover 1.21.2 – 26.3 across 15 release versions, and the latest Fabric file is v1.1.6 for 26.3, published 2026-10-01.
Key features

Use cases
Aiming ender pearls
A player can check the landing spot of an ender pearl before throwing it, reducing missed teleports.
Planning potion throws
Splash potions can be aimed at a target with the predicted path in view before the throw.
Who it’s for: Players who throw snowballs, ender pearls or potions and want to see the landing point before throwing. The mod is a client-side Fabric mod, so it suits single-player worlds and servers where the owner allows client mods. Some multiplayer servers treat aim assistance as a gameplay advantage, so players should check the server rules before using it.
