Curvy spline to 2D Edge collider

[_Aka_]

Hi,
I got a question from a user about how to convert a spline to 2D Edge collider. I wrote a small script for him that does so. I post it here, maybe it will help someone else:

Code:

using FluffyUnderware.Curvy; using UnityEngine; [RequireComponent(typeof(CurvySpline))] [RequireComponent(typeof(EdgeCollider2D))] [ExecuteInEditMode] public class CurvySplineToEdgeCollider : MonoBehaviour {    private EdgeCollider2D edgeCollider;    private CurvySpline spline;    void OnEnable()    {        edgeCollider = GetComponent<EdgeCollider2D>();        spline = GetComponent<CurvySpline>();        spline.OnRefresh.AddListenerOnce(OnRefresh);        RebuildCollider();    }    void OnDisable()    {        spline.OnRefresh.RemoveListener(OnRefresh);        edgeCollider = null;        spline = null;    }    private void OnRefresh(CurvySplineEventArgs arg0)    {        RebuildCollider();    }    private void RebuildCollider()    {        if (spline.Interpolation != CurvyInterpolation.Linear)            Debug.LogWarning("Spline's interpolation should be Linear. Current value is " + spline.Interpolation);        if(spline.ControlPointCount < 2)            Debug.LogWarning("Spline should have at least two points. Current count is " + spline.ControlPointCount);        else        {            Vector2[] newPoints = new Vector2[spline.ControlPointCount];            for (int i = 0; i < newPoints.Length; i++)            {                newPoints[i].x = spline.ControlPoints[i].transform.localPosition.x;                newPoints[i].y = spline.ControlPoints[i].transform.localPosition.y;            }            edgeCollider.points = newPoints;        }    } }

Another version that works with curved splines

Code:

using FluffyUnderware.Curvy; using UnityEngine; [RequireComponent(typeof(CurvySpline))] [RequireComponent(typeof(EdgeCollider2D))] [ExecuteInEditMode] public class CurvySplineToEdgeCollider : MonoBehaviour {    [Range(2,100)]    public int PointsCount = 20;    private EdgeCollider2D edgeCollider;    private CurvySpline spline;    void OnEnable()    {        edgeCollider = GetComponent<EdgeCollider2D>();        spline = GetComponent<CurvySpline>();        spline.OnRefresh.AddListenerOnce(OnRefresh);        RebuildCollider();    }    void OnDisable()    {        spline.OnRefresh.RemoveListener(OnRefresh);        edgeCollider = null;        spline = null;    }    private void OnRefresh(CurvySplineEventArgs arg0)    {        RebuildCollider();    }    private void RebuildCollider()    {        if(spline.Count == 0)            Debug.LogWarning("Spline should have at least one segement.");        else        {            Vector2[] newPoints = new Vector2[PointsCount];            for (int i = 0; i < PointsCount; i++)            {                float tf = (float)i / (PointsCount - 1);                Vector3 position = spline.Interpolate(tf);                newPoints[i].x = position.x;                newPoints[i].y = position.y;            }            edgeCollider.points = newPoints;        }    }    private void OnValidate()    {        if(spline)            RebuildCollider();    } }
