How did they implement this?

Unity Engine

This is for siege weapon targeting and I’m looking to do something very similar. It’s probably going to take a bit of work so wondering if my thinking is close or if there is an easier way.

This looks to me like just a mesh with a transparent gradient shader and gradient plus some noise for the target end point. Not shown in these images well but the trajectory ribbon can have an obvious arc when viewed from more of a side angle.

In the first picture there is also a white band there, that moves along the ribbon. that part not as important.

What I’m wondering if is something like a line renderer would work here, or if generating a mesh every frame looks to be the best approach (for the ribbon).

The arc itself could be a multi-point line renderer. Calculate the ballistic arc, add a point every x units or n time steps along the trajectory, done. The X at the end is likely another mesh simply placed at the impact location, or set of meshes, or set of line renderers. However you want to handle the individual segments being camera facing aspect of it. Lots of ways to do that part, all are perfectly valid.

Ya I ended up using line renderers for all of it and that worked out well.
