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

Not sure what that code is, but to answer your question title

c# :
Enemy Kill Character Script:

public bool noFallow;
if(other.CompareTag("Player")){
    noFallow = true;
}

Camera Follow Script:

if(Enemy Kill Character Script.noFallow == false){
    //fallow the player
}else{
     //load the level or do any thing
}
