Trajectorys
by ProjectMichi
With Trajectorys installed, a player holding a bow, crossbow or throwable item sees the predicted flight path as a parabolic line before releasing it.
What it does
Trajectorys is a client-side Fabric mod that draws the trajectory of projectiles such as arrows, crossbow bolts and thrown items. The predicted path is shown as a line while the item is held, and the point where it would land is highlighted with a box, so a shot can be checked before it is fired. The mod also shows the path of projectiles that are already flying, and it can display trajectories for other players who hold items when that option is enabled.
The mod depends on Simple GUI API, which must be installed alongside it. Its settings can be changed in-game through a configuration screen when Mod Menu and Cloth Config API are present. Trajectorys runs on the client only, so servers need nothing installed. It is published for Fabric alongside Forge and NeoForge files, covering game versions 1.21 – 26.2, under a custom license that is not open source.
Key features
Predicted flight path
The line follows the parabolic arc a held bow, crossbow or throwable item would take, updating as the item is aimed.
Highlighted impact point
The predicted landing spot is marked with a box, so precise shots and throws can be confirmed beforehand.
Flying projectile tracking
Arrows and other projectiles already in the air can have their future path displayed as they travel.
Hit and pickup alerts
A notification and sound play when a predicted shot would hit an entity, and an experience orb pickup sound can be played as an alert.
In-game settings
Display options can be adjusted in a configuration screen, which needs Mod Menu and Cloth Config API.
