For example, if you want to track the high scores for a game, you could store the scores on a
server and use
loadVariables()
the game. The function call might look like the following example:
this.createEmptyMovieClip("highscore_mc", 10);
loadVariables("http://www.helpexamples.com/flash/highscore.php",
highscore_mc, "GET");
This example loads variables from the ColdFusion script called high_score.cfm into the movie
