Invisible Buttons. Nay or Yeah?

[spoonyg]

I am wondering what peoples out there use for buttons. Ive been using invisible buttons. I make one button with a hit state and stick that over anything that i need as a button, in a movieclip. Then i just have one button in my library. I always thought the advantage was a smaller library. Do other people use invisible buttons out there? Does anybody know the disadvantages of lots of different buttons?

spoonyg,

There are two main advantages of re-using buttons :

1) Keeps file size down

2) Ideal for keeping a flowing / constant theme throughout your site.

Personally i only really use invisible buttons for creating dragable MC's.

Invisible buttons are also ideal for using on text, i.e. if the user wants to enlarge a smaller chunk of text. Invisible buttons inside MC's are good, but it can lead to slightly innacurate HIT areas - if you haven extremely odd shaped MC for example.

Hope this was of some help
