Disclaimer: not a game programmer so I could be completely wrong. If you’ve implemented hitscan, the easiest implementation would be to find other players within some distance along the ray, and play some sound effect where the intensity of the whizzing sound is a function of the other players distance from the ray. The whizzing sound should provide some sense of direction of the bullet relative to the direction another player is facing. Possibly playing a pre recorded sound from a map of available sounds? Eg a bullet rushing from your 2 o’clock just past your shoulder? Or you could try to mix the sound and create that effect in real time I suppose.
