Analyzing waypoints by cover and visibility

When dealing with military games, especially FPS, we need to define a waypoint value, by its capacity, to be a good cover point with the maximum visibility for shooting or reaching other enemies visually. This recipe helps us compute a waypoint's value given these parameters.

Getting ready

We need to create a function for checking whether a position is in the same room as others:

public bool IsInSameRoom(Vector3 from, Vector3 location, string tagWall = "Wall")
{
    RaycastHit[] hits;
    Vector3 direction = location - from;
    float rayLength = direction.magnitude;
    direction.Normalize();
    Ray ray = new Ray(from, direction);
    hits = Physics.RaycastAll(ray, rayLength);
    foreach (RaycastHit h in hits)
    {
        string tagObj = h.collider.gameObject.tag;
        if (tagObj.Equals(tagWall))
            return false;
    }
    return true;
}

How to do it…

We will create the function that computes the quality of the waypoint:
