Problem updating animation with intervals

Hello guys, first question over here, i'm really new with unity(1 and 1/2 weeks), i picked it up because i need to make a mobile app for uni.

So my question is the following, i have this animation (basically it's a scale and color alpha change), but i only want to run in within a timed interval, i cant put my head arround it, i'm sure i'm missing something easy.

Please check it out! Thanks in advance, Roger

 public float alphaStart;
 public float alphaEnd;
 public float duration;
 public float interval;
 public float targetscaleMul;
 public float force;
 public float forceradius;
 private float start;
 private float actual;
 private bool active;
 private float lerp;
 private Vector3 originalLocalScale=Vector3.zero;
 private Vector3 originalLocalScaleaux=Vector3.zero;
 private Vector3 targetLocalScale=Vector3.zero;
 private float alphaaux;
 private Color newc;
     void Start () {
     start =Time.time;
     actual =Time.time;
 
     active=false;
     originalLocalScale=transform.localScale;
     targetLocalScale=transform.localScale;
     targetLocalScale.y=originalLocalScale.y*targetscaleMul;
     newc=renderer.material.color;
 }
     void Update () {
         actual=Time.time;
         if(active){
             fazanim();
         }else{
             if(actual>=(start+interval)){
                 fazanim ();
             }
                 
         }
     private void fazanim(){
         
         if(!active){
             active=true;
             start=Time.time;
         }
             
         if(active){
             if((actual-start)>=duration*2){
                 newc.a=alphaStart;
                 renderer.material.SetColor("_Color",newc);
                 transform.localScale = originalLocalScale;
                     
                 start=Time.time;
                 active=false;
                 return;
             }    
             
             lerp = Mathf.PingPong(actual,duration)/duration;
             alphaaux=Mathf.Lerp(alphaStart,alphaEnd,lerp);
             newc.a=alphaaux;
             renderer.material.SetColor("_Color",newc);
             transform.localScale = Vector3.Lerp(originalLocalScale, targetLocalScale,lerp);
             
             }
             
         }

what i intended with the interval float is to space out the anim. ex : wait interval. do animation.wait interval . do animation. wait..

but this implementation is basicly skipping the anination the interval ammount

Have you tried to replace your animation script to something simple like Sin? i.e:

 alphaaux=Mathf.Sin(Time.time);
          newc.a=alphaaux;
          renderer.material.SetColor("_Color",newc);

First off, your update code is a waste. The logic you have in there is:

 if(something) 
     runA(); 
 else if(somethingElse) 
     runA();

Why not simply runA? By that I mean get rid of runA and move the code to update.

Also in my experience you're doing timers in a rather unconventional way. I've seen them mostly as:

 float TIMER_DURATION = 2.0f; //Two second timer
 float m_timer = 0f; //Countdown timer
 
 //... somewhere in update
 if(m_timer <= 0f)
 {
     //timer is done. do timer ended logic.
     //and then reset your timer.
     m_timer = TIMER_DURATION;
 }
 m_timer -= Time.deltaTime;
 

You're code is more complex than it needs to be. Simplify it and put some Debug.Logs in various places to verify what numbers you're getting. I would start with Debug.Log(lerp);. I also would put some around to make sure things are getting called in the correct order. Debug.Log("starting anim"); Debug.Log("stopping anim"); Debug.Log("animating");

tryed with a coroutine, same results, what am i not seeing???

 void Update () {
     actual=Time.time;
     if(actual>=(start+interval) && !active){
         StartCoroutine(fazanim ());
     }
     
 }
 
 
 
 private IEnumerator fazanim(){
         
             if(!active){
                 active=true;
                 start=Time.time;
             }
             
             if(active){
             while(true){
                 if((actual-start)>=duration*2){
                 //yield return new WaitForEndOfFrame();
                     newc.a=alphaStart;
                     renderer.material.SetColor("_Color",newc);
                     transform.localScale = originalLocalScale;
                     
                     start=Time.time;
                     active=false;
                     
                 }    
                 yield return new WaitForEndOfFrame();
                 lerp = Mathf.PingPong(actual,duration)/duration;
                 alphaaux=Mathf.Lerp(alphaStart,alphaEnd,lerp);
                 newc.a=alphaaux;
                 renderer.material.SetColor("_Color",newc);
                 transform.localScale = Vector3.Lerp(originalLocalScale, targetLocalScale,lerp);
             }
             }
             
         }
