Improve spawning position

[DreamersIncStudios]

Improve Spawner System by either doing a downward ray cast or getting navmesh position to determine floor position. Adding a Vertical offset to the spawn SO. This will make sure the spawned GO always instantiates are appropriate height

Code below does not function as expected in ComponentSystem.

 bool RandomPoint(Vector3 center, float range, out Vector3 result)
        {
            for (int i = 0; i < 30; i++)
            {
                Vector3 randomPoint = center + UnityEngine.Random.insideUnitSphere * range;
                NavMeshHit hit;
                if (NavMesh.SamplePosition(randomPoint, out hit, 1.0f, NavMesh.AllAreas))
                {
                    result = hit.position;
                    return true;
                }
            }
            result = Vector3.zero;
            return false;
        }
