how can i make my character bounce without a rigidbody

[system]

im trying to make a simple game that my character (a ball) bounce around the world

1. i add my character movearoud
2. i add a bounce physic material to my platform
   when i play my game it doesnt work until i add a rigidbody to my character but when i did that my character start jumping like crazy
   here is my movearoud script

private var dead = false;
var speed = 6.0;
var rotateSpeed = 3.0;
var bullitPrefab:Transform;
var lifeTime = 1.0;

function LateUpdate()
{
if(dead)

{

if(dead) { transform.position = Vector3( 0,4,0); dead = false; }
}

}

function OnControllerColliderHit(hit : ControllerColliderHit)
{ if(hit.gameObject.tag == “fallout”)
{ dead = true; //substract life here

             HealthControl.LIVES -= 1;

}

}

function Update ()
{
var controller : CharacterController = GetComponent(CharacterController);
// Rotate around y - axis
transform.Rotate(0, Input.GetAxis (“Horizontal”) * rotateSpeed, 0);
// Move forward / backward
var forward = transform.TransformDirection(Vector3.forward);
var curSpeed = speed * Input.GetAxis (“Vertical”);
controller.SimpleMove(forward * curSpeed);
if(Input.GetButtonDown(“Jump”))
{
var bullit = Instantiate(bullitPrefab,GameObject.Find(“spawnPoint”).transform.position, Quaternion.identity);
// shoot the bullet at 10m/s
bullit.rigidbody.velocity = transform.forward * 50;

}
}

@script RequireComponent(CharacterController)

use the code button, if you can!

Basically, every time your object collides with the object you want it to bounce off of, just move it accordingly. Use an easing function of some kind.
