Script making unity stop responding(JS)

So I have been working on a simple script to make my character float on water, but whenever I run the script, Unity stops responding. I'm sure there is a better way to write the script, so if you know on,e help would be appreciated, but I just need to know why Unity is crashing.

Code (JavaScript):

1. #pragma strict
2. var Player : GameObject;
3. var InWater : boolean = false;
4. function Start(){
5.     Player = this.gameObject;
6. }
7. function Update(){
8.     while(InWater == true){
9.         Player.GetComponent.<Rigidbody>().AddForce(Vector3.up * 2 * Time.deltaTime);
10.     }
11. }
12. function OnTriggerEnter(other : Collider){
13.     if (other.gameObject.tag == "water"){
14.         Debug.Log("InWater");
15.         InWater = true;
16.     }
17. }
18. function OnTriggerExit(other : Collider){
19.     if (other.gameObject.tag == "water"){
20.         Debug.Log("OutWater");
21.         InWater = false;
22.     }
23. }
24.  

I have tried changing the AddForce(Vector3.up*2*Time.deltaTime); line to different numbers, even removing it, but it wont work. Thanks in advance!

most of the time you don't need while loops in update, update is already a game loop.

 

My error there! I usually don't use while loops, so I just stuck it in there. Thanks for the help!
