Realistic Bazooka

I’ve been searching around the forum and I haven’t found anything related to a Realistic Bazooka. What I mean by realistic is that the bazooka fires the rocket but in time it starts to go down. Like on the game Worms or something similar. If you don’t quite understand what I mean, it’s this:

(User was banned for this post ("Wrong section" - mahalis))

So it shoots out at a 45 degree angle then curves?

I mean it gets pulled by gravity. So it doesn’t go straight

Somewhat like the TF2 grenade launcher, except rockets?

It would be a regular grenade launcher.

So does anybody have any clue how to do this?

I would say spawn a normal entity give it some forward speed, and then let source handle the rest?

Well, I know that this concept has been done before in GMod. Check around.
