my guess:
LineRenderer lineRenderer = (LineRenderer) gameObject.AddComponent("LineRenderer");
if(lineRenderer== null) {
Debug.Log("null lineRenderer");
}
lineRenderer.SetVertexCount(2);
lineRenderer.SetColors(c1, c2);
lineRenderer.SetPosition(0, start);
lineRenderer.SetPosition(1, end);
lineRenderer.SetWidth(width, width);
Debug.Log("rendered line");
fails when i try to add many lines :
Can't add component 'LineRenderer' to Ground because such a component is already added to the game object!
how can i have many lines?
