I’m trying to make a preloader, and I have the code in the first frame. Then in a layer above that one I have the Loading Animation to play while the preloader is working… But they don’t work…
Any ideas why not?
Add this code on the 2nd frame
[AS]gotoAndPlay(1);[/AS]
then extend the layer where you have the preloader component by 1 frame.
Hope it helped.
