An Age gate, pass it the age you want as a minimum to see your content (defaults to 16), and alternatively a debug boolean if you want them to be able to try again (defaults to false). This example sets a random age when the swf is loaded.
eg. if the movieclip for the age gate has an instance name ‘ageGateClip’
ageGateClip.setAge(16)
ageGateClip.debug = true
