@Sad_Man30 That's easy to do in 2 ways!

  1. Create an empty gameObject and just add a box collider to it and you're done!

  2. However if you're having a wall sprite and wanna make that invisible just go to sprite renderer and disable the component make sure that it has a collider if you wanna make the wall visible again you just have to enable the sprite renderer again!

Though i think 1st way is all you need. For saying that you need few lines of code

 public GameObject text; // your text ui
 
 OnCollisionEnter2D (Collision2D other){
        text.SetActive(true) ;
 }
 
 OnCollisionExit2D (Collision2D other){
        text.SetActive(false) ;
 }
