Hello everyone. I can't understand why the constructor returns null? What is the problem? Both scripts are inherited from MonoBehaviour
public void Create()
{
float length = 2f;
int polygonNumber = 6;
if (_polygonal != null)
_polygonal.Destroy();
if (length < 1)
length = 1;
if (polygonNumber < 4)
polygonNumber = 4;
else if (polygonNumber > 8)
polygonNumber = 8;
var pointsPositions = CreatePolygonlPoints(length, polygonNumber);
var _material = lineRendererMaterials[Random.Range(0, lineRendererMaterials.Length)];
_polygonal = Instantiate(new Polygonal(pointsPositions, _material, length));
Debug.Log(_polygonal);
}
Script Polygonal
public Polygonal(List points, Material _material, float _length)
{
Length = _length;
PointCount = points.Count;
_gameObject = Instantiate(new GameObject(), Vector3.zero, Quaternion.identity);
var lineRenderer = _gameObject.AddComponent();
lineRenderer.material = _material;
lineRenderer.startWidth = 0.06f;
lineRenderer.endWidth = 0.06f;
lineRenderer.positionCount = points.Count - 1;
for(int i = 0; i < points.Count - 1; i++)
{
lineRenderer.SetPosition(i, points[i]);
}
}
I get error 2
