how do you make a raycast hit do something for varying distances?

So hopefully this is an easy one.

I have a series of objects tagged “Pods-Leader” all running on along a path animation that i have brought in from an fbx file from 3dsmax.
The problem i am having is getting the animation state to stop and start basted on the raycast distance. It works when i am setting the distance for it to slow and speed up. But i would like it to set the speed back to 1.0 if a ray hasn’t hit after say 3 seconds.

This is the js code i am using.

#pragma strict

function Update () {
	var hit : RaycastHit;
	if (Physics.Raycast(transform.position, transform.forward, hit, 15.0 ))
		{
			if(hit.collider.gameObject.tag == "Pods-Leader")
			{
			 	GetComponent.<Animation>()["PodMovement"].speed = 0.75;
			 	}
			 	
 	if (Physics.Raycast(transform.position, transform.forward, hit, 7.5 ))
		{
			if(hit.collider.gameObject.tag == "Pods-Leader")
			{
			 	GetComponent.<Animation>()["PodMovement"].speed = 0.5;
			 	}
			 				 	
	if (Physics.Raycast(transform.position, transform.forward, hit, 5.0 ))
		{
			if(hit.collider.gameObject.tag == "Pods-Leader")
			{
			 	GetComponent.<Animation>()["PodMovement"].speed = 0.0;
			 	}
				Debug.DrawLine (transform.position, hit.collider.transform.position,Color.red);
			}

}
	
}
}

Any help would be gratefully received.

Thanks.

You can use a timer to check the last time it was hit and then set the timer based on that timer value. Something like:

#pragma strict

var lastHitTime = 0;

function Update ()
{
    var hit : RaycastHit;
    if (Physics.Raycast(transform.position, transform.forward, hit, 15.0 ))
    {
            if(hit.collider.gameObject.tag == "Pods-Leader")
            {
                GetComponent.<Animation>()["PodMovement"].speed = 0.75;
            }
                  
		if (Physics.Raycast(transform.position, transform.forward, hit, 7.5 ))
        {
            if(hit.collider.gameObject.tag == "Pods-Leader")
            {
                GetComponent.<Animation>()["PodMovement"].speed = 0.5;
            }
        
			if (Physics.Raycast(transform.position, transform.forward, hit, 5.0 ))
			{
				if(hit.collider.gameObject.tag == "Pods-Leader")
				{
					GetComponent.<Animation>()["PodMovement"].speed = 0.0;
				}
					Debug.DrawLine (transform.position, hit.collider.transform.position,Color.red);
			}
 
		}
		lastHitTime = 0.0;
	} else 
	{
		// Since there was no hit add time to the lastHitTime
		lastHitTime += Time.deltaTime;
		
		if(lastHitTime > 3.0)	// This means your last hit time was before 3 seconds
		{
			GetComponent.<Animation>()["PodMovement"].speed = 1.0;
		}
	}
}
