Set a static boolean for the enemies to check, and when the character triggers the power-up, set the boolean appropriately to prevent your enemies from moving quickly. From there have a timer for your enemy scripts to set the boolean back to true.

*Note that I did not test any of this in Unity, it's just an example of how I might achieve this result.

For example, inside your power-up script:

function OnTriggerEnter(other : Collision)
{
    // You may want to add an if check here to make sure it is the
    // player entering your powerup
    enemyScript.enemySlowDown = true;
}

And for your enemies:

var timeToSlow : float = 5.0; // This will be the amount of seconds to slow your enemies private var countDown : float; static var enemySlowDown : boolean = false;

function Awake() { countDown = timeToSlow; }

function Update() { if (enemySlowDown) // Check to see if character has hit the powerup { countDown -= 1 * Time.deltaTime; // Begin countdown in actual time if(countDown <= 0) // If countdown is finished reset everything { enemySlowDown = false; countDown = timeToSlow; } } }

GREAT script, everything slows down just like should, but the timer doesn't work. they just stay slow, and i didn't change anything.
