Help With Interaction Design

I have looked for about an hour now and can’t find a solution so I came here. I am trying to make an interaction circle like the one from GTA 4 (photo below). I don’t need any scripting help as I already have that, I just don’t know how to make a game object like this, would I use a particle system or sprite, I don’t know…100747-untitled.png

It depends, you could supposedly make a cylinder object without a top and both and apply a fading texture to the faces? Or you could use the particle system (Which may cause some lower performance but is more customizable than a still texture.)
