"Error triangulating mesh. Aborted." Error

[MrFlox]

I'm trying to make test mesh from 4 points and get this error:

Error triangulating mesh. Aborted.
UnityEngine.Debug:LogError(Object)
Sebastian.Geometry.Triangulator:Triangulate() (at Assets/Ear-Clipping-Triangulation/Triangulator.cs:72)
Sebastian.Geometry.CompositeShape:Process() (at Assets/Ear-Clipping-Triangulation/CompositeShape.cs:87)
Sebastian.Geometry.CompositeShape:GetMesh() (at Assets/Ear-Clipping-Triangulation/CompositeShape.cs:29)
TrianTest:Start() (at Assets/TrianTest.cs:29)

This is my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

using Sebastian.Geometry;


public class TrianTest : MonoBehaviour {

    public MeshFilter meshFilter;
    public List<Shape> shapes = new List<Shape>();

    Shape basicShape = new Shape();

    void init(){
        shapes.Add(basicShape);
    }
	void Start () {

        init();

        addPointToShape(-1.0f, 0.0f);
	addPointToShape(1.0f, 0.0f);
        addPointToShape(1.0f, 2.0f);
        addPointToShape(-1.0f, 2.0f);

        CompositeShape compShape = new CompositeShape(shapes);
        meshFilter.mesh = compShape.GetMesh();
	}
	
    void addPointToShape(float newX, float newY) {
        basicShape.points.Add(new Vector3(newX, newY,0));
    }
}

did you manage to fix this? ty!

[fumobox]

basicShape.points.Add(new Vector3(newX, 0, newY));

CompositeShapeData ignores y coodinates. Try to swap z for y.
