Trajectory Fabric
Simulates a fake projectile and traces its path, supported currently are ender pearls, snowballs, eggs and arrows. Also shows a box for the collision point, and a 2nd box for the approximate area around it that the projectile might land in (due to the randomness of projectiles).
Note: using this mod on a server could be considered cheating, if you're going to use it on a server then I'd advise you to first have permission from staff/admin.
Config:
Uses the command /trajectory to set color (RGBA) of the line, toggle visualization of components, toggle arrow trajectory rendering, and set the origin of the line between left hand, right hand, or auto.
