Description

Calculates the Lerp parameter between of two values.

	var walkSpeed = 5.0;
	var runSpeed = 10.0;
	var speed = 8.0;

function Start() { // parameter is now 3 / 5 var parameter : float = Mathf.InverseLerp(walkSpeed, runSpeed, speed); }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float walkSpeed = 5.0F;
    public float runSpeed = 10.0F;
    public float speed = 8.0F;
    void Start() {
        float parameter = Mathf.InverseLerp(walkSpeed, runSpeed, speed);
    }
