Collision,physics and animation problem?

I have this code here: private var red_right_left_moved=false;

private var red_left_right_moved=false; private var red_left_right_moved2=false;

private var red_back_front_moved=false;

function Update () {

var screenCenter = new Vector3(0.5F, 0.5F, 0);

var ray = Camera.main.ViewportPointToRay(screenCenter);

var hit : RaycastHit;

//right left 1

if(Input.GetButton("Fire1")&& red_right_left_moved==false){

if (Physics.Raycast (ray, hit, 1000)) {

 if(hit.transform.tag=="red_right_left"){
 
    hit.transform.animation.Play("anim1");
 
    red_right_left_moved=true;
 
 }
 

}

}

....etc....

The goal here is that the animated box that i moved should collide with the character controller but it doesn't. It collides after the animation end, but i want to push my character if the box is moving. How can i do that?
