I attach a script to a simple cube which bounded by four other cube. But when I play, unity stops responding. Is anything wrong in my script, or any other suggestion please ?

using UnityEngine;
using System.Collections;

public class gunf : MonoBehaviour {

public int sec;
public float value;
public float ras;
public bool isDown;

public Rigidbody rb;
// Use this for initialization
void Start () {
	rb = GetComponent<Rigidbody> ();
}

// Update is called once per frame
void Update () {

}

void FixedUpdate () {
	while(Input.GetMouseButtonDown (0) && isDown == false){
		isDown = true;
		ras = Random.Range (10f, 40f);
		rb.AddForce (transform.up * ras);
		Debug.Log (ras);
		isDown = false;
	}
}

}

Sorry for bad english.

From what I can understand it seems as though you just want to check when the user clicks the mouse, so you could try this instead:

 void FixedUpdate ()
 {
     if (Input.GetMouseButtonDown (0))
    {
         ras = Random.Range (10f, 40f);
         rb.AddForce (transform.up * ras);
         Debug.Log (ras);
     }
 }

I would think it’s probably unnecessary to use FixedUpdate(). Update() is probably fine.
Hope this helps.
