Simple example of building a Path grid

PathGrid.cs

// Given: float width, float height, float xSpacing, float ySpacing, Vector3 gridStart

Waypoint[] points = new Waypoint[width * height];

for (int y = 0; y < height; y++)
{
	for (int x = 0; x < width; x++)
	{
		points[y * width + x] = new GameObject (string.Format ("Grid-{0}-{1}", x, y), typeof (Waypoint)).GetComponent<Waypoint> ();
		points[y * width + x].transform.position = gridStart + Vector3.z * ySpacing + Vector3.x * xSpacing;
	}
}

for (int y = 0; y < height - 1; y++)
{
	for (int x = 0; x < width - 1; x++)
	{
		new Connection (points[y * width + x], points[y * width + x + 1]);
		new Connection (points[y * width + x], points[(y + 1) * width + x]);
		// TODO: Setup of connection data
	}
}
