Hi there, I am a bit confused on how to leave a mark of some sort (maybe a simple green dot) after i click a spot on the field for my person to move to.

First of all, you must find the 3D point clicked, what you can do using Raycast. You may have a mark object - a sphere, for instance - and move it to the hit point, like this:

var mark: GameObject; // drag the mark object here, if any
...
  var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
  var hit: RaycastHit;
  if (Physics.Raycast(ray, hit)){
    if (!mark){ // create a sphere if no object assigned yet
      mark = GameObject.CreatePrimitive(PrimitiveType.Sphere);
      mark.renderer.material.color = Color.green;
      mark.collider.isTrigger = true; // make it a trigger
    }
    // move the sphere to the clicked position
    mark.transform.position = hit.point;
  }
...

You can create the mark object and drag it to the field mark (a green sphere will be created if there’s no mark object assigned to mark)
