Example for using water (basic) in C#

Hi Guys:

Working on a procedural generation project where I would like to get water (basic) displaying correctly.

NOTE: I have read link text.

I think the problem is my basic lack of understanding of meshes... but I was wondering if someone could give me a coded example of using:

 water.AddComponent<waterSimple>()

At the moment I am using:

 public void InstantiateWater()
     {
         float height = CalculateAverageHeight () ;
         GameObject water = GameObject.CreatePrimitive(PrimitiveType.Plane);
         water.renderer.material = (Material)Resources.Load ("Water/Sources/Materials/DayWater");
         water.transform.parent = GameObject.Find ("myTerrain").transform;
         water.transform.localScale = new Vector3 (50f,1f,50f);
         water.transform.position = new Vector3 (256f, height, 256f);
         water.name = "water";
     }

Which obviously doesn't behave correctly because it is using a plane instead of a mesh.

Anyway Thanks in advance
