Sightline

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.

Configuration

Sightline supports ModMenu for in-game configuration. You can also manually edit the config/projectiles.json file.

Available settings:

• Immersive Colors: Color-matches the trajectory line to the projectile item.
• Visibility Mode: Choose how the trajectory is shown (Hold key, Toggle with key or Always).
• Show Hitboxes: Toggles the wireframe outline of the block or entity at the predicted impact point.
• Line Thickness: Adjust the thickness of the trajectory line (Thin, Normal, Thick).
