This took me about 2 hours to make. I didn't feel like making a prev frame button, but I made one at the end of the tutorial.
All instance names are "CASE SENSITIVE!!!" so check that before you complain in your reviews on how it doesn't work. And if it doesn't work then you did something wrong, go back and check it very carefully... I know that it works because the preloader at the beginning works!
This is also my first Tutorial... There wasn't a good AS3 preloader tutorial on NG so I decided to make one.
Hope that this helps you. And feel free to ask me if your not clear about any of the technical names
(ex: instance names).
