A text box is a simple device that allows the player to type information into your game. Adding a text box works like adding the other types of control.

If a text box is on a currently displayed GUI, all standard keypresses (ie. letter keys, return and backspace) are diverted to the textbox instead of being passed to the on_key_press function. When the player presses Return in the text box, the OnActivate event is called. You can then use the TextBox.Text property to retrieve what they typed in.
