View source for OLPCities/Keyboard

This library is part of the <b>Gamelib</b>, created by Scott Porter and updated by Brent Silby.  Gamelib is available   under the terms of the [http://www.gnu.org/copyleft/lgpl.html GNU Library General Public Licence]. 


To use this library (this Class) add  this line to the <HEAD> section of the web page of the Lot: 
<pre>
<script language="Javascript" src="http://www.dmu.com/olpc/gamelib_keyboard.js"></script> 
</pre>

Better to click this link and "save"  the library at the same folder of the web page or put it at another folder at the same server and make a reference:

[http://www.dmu.com/olpc/gamelib_keyboard.js gamelib_keyboard.js ]

If you put it at the same folder, the line would be:
<pre>
<script language="Javascript" src="gamelib_keyboard.js"></script> 
</pre>

To create an "object" of the Class you define the keyboard key. Examples:

<pre>
upkey = Kb_trapkey("UP");
Gkey = Kb_trapkey("G");
</pre>

The case is not considered.


There are only one property for this object and it's used testing if it's true or not (inside a "timer loop"). Example:

<pre>
if(upKey.pressed){
  // do something
}
</pre>
