How can I make a button whose collider is bigger than the button itself?
Do I need to hack on that or is there a clean way in 4.6?
When searching for it, I found some threads but to me this seems like there must be a (better) solution. This problem is decades old so I assume Unity has already a proper solution in 4.6.
You can add a child image where you would put your button graphic then on the button component reference that child image. Then in the image component on the object where the button script is, make that an empty image. Resize that same object as large as you want the hit area to be and size the child image to be as big you want the button.
