SetNormalAndPosition(Vector3, Vector3)

Sets a plane using a point that lies within it along with a normal to orient it.
public void SetNormalAndPosition(Vector3 inNormal, Vector3 inPoint)

Parameters

inNormal

Vector3
The plane's normal vector.

inPoint

Vector3
A point that lies on the plane.

Remarks

Note that the normal must be a normalised vector.
using UnityEngine;public class Example : MonoBehaviour{    public float fieldLength;    public float fieldWidth;    public Plane goalLine1;    public Plane goalLine2;    public Plane leftSideLine;    public Plane rightSideLine;    void Start()    {        // Set up goal lines of a playing field.        goalLine1.SetNormalAndPosition(Vector3.forward, Vector3.forward * fieldLength / 2);        goalLine1.SetNormalAndPosition(-Vector3.forward, -Vector3.forward * fieldLength / 2);        // Set up side lines.        leftSideLine.SetNormalAndPosition(-Vector3.right, -Vector3.right * fieldWidth / 2);        rightSideLine.SetNormalAndPosition(Vector3.right, Vector3.right * fieldWidth / 2);    }}
