How Do I get A reference To A Button

In my canvas I have 4 buttons. When I click the first button I want to make 2 of the other buttons to become invisible. My script is on the canvas and all the onClick functions are in that script. So How can I get a reference to some specific buttons on that canvas so I can disable them? I am assuming I just set enable = false once I get the reference, but I don't know how to get the reference.

EDIT:
currently I am using FindGameObjectWithTag but then I have to create tags for every object. I can for see 100 tags. And I'm cool with that but I don't know if that is the best way, any help would be appreciated.

 

Well, I feel stupid, I never realized there if just a Find() where I can use the name of the button. So I don't have to create a 100 tags

 

Actually, there is a better way to get what you want. Just create in your script four public variables:

public class ButtonsController : MonoBehavior {

public Button Button1;
public Button Button2;
public Button Button3;
public Button Button4;
................
}

After that go to Unity and select canvas with your script. You will see four new fields on it. Then just drag corresponding game objects (buttons) in this fields and you can use their in the script.

 

Thanks, I am not used to this work flow and forgot about that.
