Help with first UI attempt?

Hey guys, I'm Kieran. I'm still pretty new to Unity, studying it as part of a program in game-audio. I'm building a simple beat em up game, in the style of TMNT Arcade, or Simpsons arcade, and I wanted to include some onscreen text-based dialogue. I followed along with a few tutorials, and put together a scene to test out making textboxes. For my test scene, I followed this one pretty closely (

), but after putting it together, I am having a couple of problems.

I have a text-question, with three buttons below representing different response options. However, when I play the scene none of the buttons are actually clickable. Nothing happens when I click on any of the buttons, when each should change the above text.
Also, none of the buttons are highlighted, and moving my up/down, or hitting select does nothing. I want to make sure my game is playable on any generic 4 button controller/joystick. So I'd like the top response option to start as highlighted, and move the highlight with the up/down buttons, and I'd like to choose the option with the "select" button input, which I have mapped to a joypad button.

None of the tutorials I have found have addressed this specifically. Should I be doing this with a script? In the animator? Any advice?

thanks,

Check that you have an EventSystem in the scene, and a Graphics Raycaster on your canvas.

Normally these are added automatically when you create the buttons. But there are ways to accidentally remove them or not create them.

 

Ok, thanks for that. I checked, and double checked, and I do have both a graphic raycaster, and an event system. So now I'm at the point where my buttons are clickable, and they do work as intended. However, until I make the first click, I get no control response from the controller. Weird part is, I can use the controller to change my selection up/down, and make a new button press after I click it first. Do you know how I can make the controller input work the first time?

 

Ok, I finally figured it out. The event system has a field called "First Selected". Drag in your option 1 game object, and boom. Works like a charm.
