I am trying to create an achievement engine, and so far it works well. There's only one problem: I don't know how to display the unlocked achievement for a certain amount of time. What I tried doing was destroying the achievement after 5 seconds, but when I unlocked it 5 seconds after I launched the test game, it never showed up.
In short: how do I make an invisible timer that I can start, stop, and reset?
Keep in mind that I am using the free edition, so try not to explain it with too many events, if possible. Thanks.
