Color.lerp is not working

Unity Engine
1

Hello, I’m trying to use the Color.lerp in my project but it doesnt works and I have no idea why.

using System.Collections;

public class ambient_light : MonoBehaviour {

    Color color1;
    Color color2;
    Color color3;

    public float intervalle_trans_color1;
    private float m_nextProc_color1;
   
    public float intervalle_trans_color2;
    private float m_nextProc_color2;
   
    public float intervalle_trans_color3;
    private float m_nextProc_color3;

    public bool trans1;
    public bool trans2;
    public bool trans3;



    // Use this for initialization
    void Start () {

        color1 = new Color(0.25f,0.25f,0.5f);
        color2 = new Color(0.25f,0.5f,0.25f);
        color3 = new Color(0.5f,0.25f,0.25f);

        intervalle_trans_color1 = 6;
        intervalle_trans_color2 = 6;
        intervalle_trans_color3 = 6;

        m_nextProc_color1 = 0;
        m_nextProc_color2 = 2;
        m_nextProc_color3 = 4;

        RenderSettings.ambientLight = color1;
   
    }
   
    // Update is called once per frame
    void Update () {


        if (trans1 == true) {

            RenderSettings.ambientLight = Color.Lerp (color1, color2, Time.time);

        }

        if (trans2 == true) {


            RenderSettings.ambientLight = Color.Lerp (color2, color3, Time.time);

           
        }

        if (trans3 == true) {

            RenderSettings.ambientLight = Color.Lerp (color3, color1,  Time.time);
           
        }
       

        if (Time.timeSinceLevelLoad >= m_nextProc_color1 )
        {
            m_nextProc_color1 += intervalle_trans_color1;
            trans1 = true;
            trans3 = false;
        }

        if (Time.timeSinceLevelLoad  >= m_nextProc_color2 )
        {
            m_nextProc_color2 += intervalle_trans_color2;
            trans2 = true;
            trans1 = false;
           
        }

        if (Time.timeSinceLevelLoad  >= m_nextProc_color3 )
        {
            m_nextProc_color3 += intervalle_trans_color3;
            trans3 = true;
            trans2 = false;
           
        }

   
    }
}

I’d like to have a loop of smooth lerp between 3 colors on the ambientLight, with this code the color is “lerp” only the first time, after that it just switch from one color to the other without “lerp”.

Just to help you understand the issue.

After one second, Time.time will be greater than 1 and as such, lerp will always return the second color.

I have already read this, I tried to replace Time.time by many things (like 1 * Time.deltatime) but it didnt works better.

In that case you should know that using Time.time doesn’t work.
Instead you may store the time in an additional variable (transStart) when the animation is started (e.g. trans1 set to true). You can then use (Time.time - transStart).

Thanks !
