So like the title says... anyone know if it would be possible to make a projectile create a waypoint where it hits/where it is on a map? Prefferably workable in multiplayer if possible. I'm not paticularly sure how it would work, outside the fact that somehow the waypoint has to be attatched to the projectile itself.

You could model in a plane on the projectile and apply the waypoint bitmap to that. You wouldn't be able to have the distance counter though.

I don't think that would remain visible over a long distance, so I don't think that would suffice. Unless there's a way to make a real waypoint on it, I'd probably be better off making the projectile a very bright light that sticks to people/objects like a plasma grenade...

In the impact effect. Go down to where it says parts, add a new part, change the type to light. Create a new light tag, link the two, and you now have a light as a waypoint. You could also add sounds. If you have the ability, you could also make a model of an arrow, and make the effect create a scenery.... But that could prove tricky.

I know how to make the point via a light effect, what I am interested in though, is some way of making an actual waypoint like how the flags in CTF or the objective areas in campaign are marked with a waypoint. I assume this would require scripting and may not even be possible in Multiplayer without using Open Sauce, but I'd still like to know what the possibilities are for this idea...

Sorry, wasn't completely sure if you knew how. I think, but I"m not 100% sure, that waypoints are scripted... And I have no idea how to make a script activate for a specific weapon firing... Or actually if there's any way of tracking the projectile, and where it hits. That's the bigger problem I think.
