moving platforms

Hi community

Im looking for a simple solution. with a this script i make the platforms in my 2D-game move. the problem is that my character cant stand on the moving platforms. im using the PlatformerController-script for my character. is there a logical solution for this?

var amplitude: float = 5; // platform excursion (+/- 5 units, in this case)
var speed: float = 0.2; // movements per second
var direction: Vector3 = Vector3.forward; // direction relative to the platform
private var p0: Vector3;

function Start(){
  p0 = transform.position;
  while (true){
    // convert direction to local space
    var dir = transform.TransformDirection(direction);
    // set platform position:
transform.position = p0 + amplitude * dir * Mathf.Sin(6.28 * speed * Time.time);
    yield; // let Unity free till the next frame
  }
}

Looks likes this fixed it mostly

function OnTriggerStay(other:Collider){

           if(other.gameObject.tag == "platform"){
           transform.parent = other.transform;

       }
    }

function OnTriggerExit(other:Collider){
    if(other.gameObject.tag == "platform"){
         transform.parent = null;

       }
    }  

Thanks guys!
