Waypoint marker that counts distance from player

Vector3.Distance(Players Position, Targets Position) This returns distance in unity units, which is the same as meters. If your objects are a different scale, you will have to adjust the given distance.

Ok, thanks. But how would I make this being displayed as a meter count under the waypoint?

Look into 3D text... you can then assign that text the output of Vector3.Distance as mentioned by Rabwin.

Using all the great info above, this is how I'd recommend putting it all together:

1. Create an empty child game object of the waypoint called DistanceLabel. This object will rotate to always face the camera (see step 3). If the waypoint object itself can rotate, then don't bother with the empty child object.

2. Add a Text $$anonymous$$esh component to it.

3. Add a script that keeps the label facing the camera -- for example:

     public Transform player;
        
        void Update() {
            float distance = Vector3.Distance(player.position, this.position);
            GetComponent<Text$$anonymous$$esh>().text = string.Format("{0:N0}m", distance);
            transform.LookAt(Camera.main.transform);
        }
