Make a 3D object interactable like a button

Hi there!

I was developing an app and now, they asked me (nicely xD) to change the entire app from GVR to AR.

Now, I had a lot of stuff done but I was thinking, just to stay with the same concept as the app was before, if I coud make an object interactable with the finger, like the object was a UI button. That woud help me to save tons of hours of work.

Thank you all, have a nice day ^^

 

Aswering my own question (for anyone who coud need it) I just used the OnMouseDown and OnMouseUp functions and then if(Input.GetButtonDown("Fire1")) and it worked.
