Color transtition not rendering

Questions & Answers
1

Hi - I’m trying to trigger and smooth color transition when I hover on a cube, and back to the original color when exiting. You’ll find the code below: it does change the color but ignores the LERP (the intermediate colors). What’s more strange is that the renderer.material.color is properly updated with all lerped values(proven by the debug log), but just not rendered on screen (only until the last value).
Not sure what Im missing.

public Color colorOn;  //change in inspector
    public Color colorOff;//change in inspector
    public float duration; //secs for the transition - change in inpector

    float t = 1;
    bool turnOn;
    bool turnOff;

    private Renderer therenderer;

void Start()
    {

        therenderer = GetComponent<Renderer>();
        therenderer.material.color = colorOff;

    }

void OnMouseEnter()
    {

        turnOn= true;
        turnOff = false;
        Debug.Log("Trun ON!!)");
        turnItOn();

    }

void OnMouseExit()
    {
        turnOn = false;
        turnOff = true;
        Debug.Log("Trun OFF!!)");
        turnItOff();
    }

void turnItOn() {
        while (t > 0 && turnOn)
        {
            therenderer.material.color = Color.Lerp(colorOff, colorOn, t);
            t -= Time.deltaTime / duration;
            Debug.Log(therenderer.material.color.ToString());
        }
        t = 1;
        turnOn = false;
    }

    void turnItOff()
    {
        while (t > 0 && turnOff)
        {
            therenderer.material.color = Color.Lerp(colorOn, colorOff, t);
            t -= Time.deltaTime / duration;
            Debug.Log(therenderer.material.color.ToString());
        }
        t = 1;
        turnOff = false;
    }

}

Thanks!

I figured it out:

using UnityEngine;
using System.Collections;

public class ChangeBarWhenHover : MonoBehaviour {


    Color colorOn = Color.gray;
    Color colorOff = Color.white;
    float duration = 0.6f;

    float t;
    bool turnOn;
    bool turnOff;

    private Renderer renderer;

void Start()
    {
        GetComponent<Renderer>().material.color = colorOff;

        renderer = GetComponent<Renderer>();
        //normal = Shader.Find("Standard");
        //hover = Shader.Find("FX/Gem");
    }

void OnMouseEnter()
    {

        turnOn= true;
        turnOff = false;
        t = duration;
        StartCoroutine (turnItOn());

        //        GetComponent<Renderer>().material.color = Color.gray;

    }

void OnMouseExit()
    {
        turnOn = false;
        turnOff = true;
        t = duration;
        StartCoroutine (turnItOff());
        //GetComponent<Renderer>().material.color = Color.white;
    }

IEnumerator turnItOn() {
        while (t > 0 && turnOn)
        {
            //print(t + " Fade in" + " Fade out");
            renderer.material.color = Color.Lerp(colorOn, colorOff, t);
            t -= Time.deltaTime / duration;
            //Debug.Log("Color oning: " + renderer.material.color);
            yield return 0;
        }

        turnOn = false;
    }

IEnumerator turnItOff()
    {
        while (t > 0 && turnOff)
        {
            //print(t + " Fade in" + " Fade out");
            renderer.material.color = Color.Lerp(colorOff, colorOn, t);
            t -= Time.deltaTime / duration;
            //Debug.Log("Color offing: " + renderer.material.color);
            yield return 0;
        }

        turnOff = false;
    }
