About this Mod
Sightline
A client-side Fabric mod that allows you to view the path of your projectiles before you shoot them.


Features
- Calculates and renders the exact trajectory of your projectile.
- Dynamically highlights the predicted impact point (blue for blocks, red for entities).
- Optional Immersive Colors setting to color-match the trajectory line to the projectile (e.g., teal for tridents, green for ender pearls).
- Configurable Visibility Modes: Hold (default), Toggle or Always Show.
- Customizable trajectory line thickness and toggleable impact hitbox rendering.
- Supports bows, crossbows, tridents, snowballs, eggs, ender pearls and splash potions.
- Fully client-side; works perfectly on multiplayer servers.
Usage
By default, hold Left Alt while holding a projectile item to display its predicted path. You can change this behavior to "Toggle" or "Always" in the configuration menu.
The keybind can be changed in the Minecraft controls menu under the "Misc" category.

Available settings:
