This tutorial is designed for newbie and intermediate Flashers. You'll need a basic understanding of Flash to complete this tutorial such as the tools palette, creating buttons, assigning actions to buttons & keyframes, and importing & exporting files. All of these are covered in the Flash manual and almost all of the Flash developer sites. You'll learn everything else you need to know for this project here so don't fret kids...
Getting started
The first thing you'll need to do is establish your stage size. As with any project, planning ahead saves time and headache later. More importantly, when using the Load movie action, each movie will need to be the same size to align correctly. We'll cover that later. For this project we'll set up a simple 400x300 stage.
Next you'll need a sound loop. You can create your own or download loops off the net. For this tutorial, I put together a little loop with Sonic Foundry's "Acid". (link it). We'll use this later, but for now we just want to gather our resources.
