How do I use Plane.GetDistanceToPoint?

Questions & Answers
1

I read the documentation on it, but I still don’t know exactly how to use it.

I’m trying to check when the player crosses a plane with the plane normal.

How do you get the distance from a plane to a point?

I can’t figure it out, please help.

This is just from my flawed understanding, but it’s better
than nothing.

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



public class PointDistance : MonoBehaviour
{

	/*The value returned is positive if the point is 
	on the side of the plane into which the plane's normal 
	is facing, and negative otherwise.*/

	/*This means transform.forward, the blue axis, in front
	of it would be positive. And behind it would be negative.*/

	//Plane is the object this script is attached to.
    private Plane mPlane;

    void Start()
    {



    }


    //This is the point that you're getting.
    public Transform mPoint;
    void Update()
    {
		//Sets direction of this Plane //Sets position of plane.
        mPlane.SetNormalAndPosition(this.transform.forward, this.transform.position);
        //Gets the distance from plane to point.
		Debug.Log(mPlane.GetDistanceToPoint(mPoint.position));

    }


}
