This is a work in progress tutorial. It's unfinished, and as such you should ignore it until it's done.

Step 1. Setting up

Create a new AS3 fla document. If you don’t see this when making a new document, choose ActionScript 3.0 on the start menu and the properties panel, set the framerate, stage size, and other properties to whatever you prefer. I usually select 30fps, 1280 x 720, with a black canvas.

Now it is time to create the actual game! Create a background for the main menu. Don't worry about making it look

good or fancy; you can always change it later.

Convert it into a symbol by pressing F8 or right-clicking and clicking "Convert to symbol". Choose MovieClip, as we need to write code for it and make it independent from the timeline. Call it menu. This will be where the game's menu is housed (duh)

Go to the root of the game

Convert the menu to a MovieClip again, and call it the game's title. Why? To prevent people from cheating by using the forward and backwards buttons >:(
