Question Buttons to elevator

So I added elevator to my game but now I want to control it with buttons, so I made public void in my elevator script and now I have no idea how to make game object a button.. I would want to make if I click on it it will activate the public void in my other script but I dont know how to make it anything I dont even know how to make a button without UI, couldnt find any help in youtube so I came here.




I got it! but idk how to delete this post XD

 

You can put a physics raycaster on the camera.
Add a collider to the elevator button.
Add a component on the elevator button with the

IPointerClickHandler

interface implemented.
For testing purposes just put a

Debug.Log("Clicked", this);

in and test if it works
