<h1>variable_global_get</h1>
<p>With this function you can get the value from a given named global variable. You supply the name of the global variable to get the value of <i>as a string</i> (see example code below) and the function will return the value
held by the global variable or <span class="inline">undefined</span> if the variable does not exist.<b></b></p>
<p class="note"><b>IMPORTANT!</b> If the global variable you are getting does not exist then the function will return the keyword <tt>undefined</tt> and you may get errors that will stop the game from functioning, so if in doubt
use the function <a href="variable_global_exists.htm"><tt>variable_global_exists</tt></a> first.</p>
<p> </p>
