* Select all the files
* Click on Import

Method 2:

* Simply drag the Unity Bezier Curve folder to your project

Usage

From Script

You can add the Bezier Curve Drawer and Bezier Curve Collider2D from script

    EdgeCollider2D collider=lineRenderer.AddComponent<EdgeCollider2D>();
    BezierCurve2D curveDrawer = lineRenderer.AddComponent<BezierCurve2D>();
    curveDrawer.drawQuadraticCurve(lineRenderer, 500, startPoint, edgePoint, endPoint);
    BezierCurve2DCollider curveCollider = linePart.AddComponent<BezierCurve2DCollider>();
    curveCollider.CreateColliderQuadraticCurve2D(collider,500,startPoint,edgePoint,endPoint);

drawQuadraticCurve() draws a line according to given parameters.

Parameters of drawQuadraticCurve()
  • LineRenderer
  • Point number between the start point and end point
  • Starting Vector3 of the Line
  • EdgePoint Vector3 of the Line
  • EndPoint Vector3 of the Line

CreateColliderQuadraticCurve2D() creates a EdgeCollider2D according to given parameters at the specified line.

Parameters of CreateColliderQuadraticCurve2D()
  • EdgeCollider2D of the lineRenderer
  • Point number between the start point and end point
  • Starting Vector3 of the Line
  • EdgePoint Vector3 of the Line
  • EndPoint Vector3 of the Line
