How do I access the contents of a script from another script?

I am a beginner at Unity I am making a 2D game and I have a character and an enemy set up. As of right now my camera follows my character but when I collide with my enemy I want my character to go flying and my camera follow script to stop following my character. How do I do this easily? Thank you in advance.

P.S. Here's the code:

 Camera Follow Script:
 
 import System.Collections.Generic;
 import UnityEngine;
 
     public var player : GameObject;
     static var offset : Vector3;
     private var offsetY : Vector2;
 
     function Start () 
     {
         offset = transform.position - player.transform.position;
     }
 
     function LateUpdate () 
     {
        transform.position = player.transform.position + offset;
     }
 
 Enemy Kill Character Script:
 
 import System.Collections.Generic;
 
 import UnityEngine;
 
 public var player : GameObject;
 
 public var script;
 
 function Start()
 {
     script = GetComponent.<CameraFollow> ();
 }
 
 function OnTriggerEnter2D(other : Collider2D)
     {
         if(other.CompareTag("Player"))
         {
             player.GetComponent.<Rigidbody2D>().velocity = Vector3(-100,100);
             script.enabled = false;
             //Application.LoadLevel(1);
         }
     }

Ignore the LoadLevel part please and my camera script is called CameraFollow and my enemy script is called KillCharacter
