I need help adding collision to my walking script

I'm currently trying to make an IOS app with unity, as you can see in the picture I have a character, boxes and two buttons

I have made a script that lets my character move when the buttons are pressed,

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4. using UnityEngine.EventSystems;
5.  
6. public class Movement : MonoBehaviour
7. {
8.     public Button storeButtonRight;
9.     public Button storeButtonLeft;
10.     public float speed = 100f;
11.     public Transform player;
12.  
13.     void OnEnable()
14.     {
15.         // storeButton.onClick.AddListener(MyFunction);//adds a listener for when you click the button
16.         storeButtonRight.onClick.AddListener(() => moveCharacter(new Vector2(1, 0f)));
17.         storeButtonLeft.onClick.AddListener(() => moveCharacter(new Vector2(-1, 0f)));
18.     }
19.  
20.     void moveCharacter(Vector2 direction)
21.     {
22.       player.Translate(direction * speed * Time.deltaTime);
23.     }
24. }
25.  

This works and all, but my main problem is that my Collision won't work, I added collision 2d objects to all the objects, but the player still walks right through them any help please?

 

You cannot modify the position of the object via the Transform component directly if you need it to interact with physics colliders. For that, you must use a Rigidbody/Rigidbody2D component to move the object.

Thanks It really helped
