It took me a really long time to figure out how to make "next frame" and "previous frame" buttons, and I only got it by piecing together random bits and pieces of information from around the web. There really didn't seem to be a simple, all in one guide to doing this, so I figured I'd make one. I learned a lot about Actionscript while making this, and I had a lot of fun with it as well. Please recommend this for the Tutorial Collection
Even though there is Actionscript text you can copy and paste, I recommend you try typing it out yourself at least once so that it sticks.
This tutorial assumes you have basic flash skills, such as creating symbols or making multiple frames.
If anything seems unclear or strange, tell me in a review and I'll do my best to clarify in a response or by editing the tutorial.
