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);
    }
}
