Character Controller NOT COLLIDING.

I tried searching for a lot answers and videos that could solve my issue but none of them seem to work. I know there's something wrong in my script, but i don't know what exactly is making my character pass through every collider. This is my script. Sorry im new to this so it might be a dumb mistake.

using UnityEngine; using System.Collections;

public class Player : MonoBehaviour {

 public Animator anim;
 public float movex = 5f;
 Vector3 movement = new Vector3(0,0,0);
 public CharacterController irena;
 public bool attacking = false;
 public float gravity = 10f;


 // Use this for initialization
 void Start () {
     anim = GetComponent<Animator> ();
     irena = GetComponent<CharacterController>();
 }
 
 // Update is called once per frame
 void FixedUpdate () {

     movement = new Vector3 (Input.GetAxis ("Horizontal"), movement.y, Input.GetAxis ("Vertical"));
     movement.y -= gravity * Time.deltaTime;

     irena.transform.Translate (movement * movex * Time.deltaTime);
 
     if (Input.GetKeyDown ("1")) {


         anim.Play ("WAIT01");

     }

     if (Input.GetMouseButtonDown (2)) {

         
         anim.Play ("WAIT04");



     }




 }

}
