How can i add interactive dialog to a character

For my game, i want to be able to talk to a character and have different actions to click on, but I have no idea how to do that.

Like mass effect where you are able to talk to a character and have different choices to choose from.

Hi,

I think you will need to use onGUI

[http://unity3d.com/support/documentation/Components/gui-Basics.html][1]

That allows you to create a GUI with text, which you can then work your branching conversations into.
