SUMMARY

This article describes how to make your application respond to key presses.

DISCUSSION

In AutoPlay Media Studio 5.0, there is an event called On Key. This event is launched whenever a key is pressed. This is useful if you want your application to, for example, play a sound every time the user presses a key.

Another use for this event is to do something only when a specific key is pressed. As an example, consider Internet Explorer. A user types in a URL into the address bar, and when they press enter, the page they requested is loaded.

To accomplish this example in AutoPlay Media Studio 5.0:

Create an input object. In it's On Key event, input the following code:

--e_Key is a built in variable. 13 is the ASCII value for [Enter]


if e_Key == 13 then


     --Loads the text input by the user


     Web.LoadURL("Web1", Input.GetText("Input1"));


end

Please note that this script assumes that you have an input object named "Input1" and a web object named "Web1".

This script reads every key pressed by the user while in the input box. When [enter] is pressed, the script loads the URL.
