Gui how to show a gui box, with text in it, like subtitles.

i Really need help with guis. do you guys know how to make a gui box, with words in it then after awhile, go away, then at a certain time come back again? like subtitles in a movie, or video game.

One way is to use the Unity GUI API. Add an OnGUI method to your script. Call GUI.Label to draw the text. Keep track of Time.time to decide when to turn the text on and off, or which text to show.

Start here to learn more about GUI scripting, and refer to the scripting reference manual for more information.
