Laying the Groundwork for No Tanks! - The Essential Guide to Flash Games - page 226

Create the GameDemo.as class
Create a new ActionScript class file called GameDemo.as . For the rest of this chapter, you will want
to set this class as the document class of the notanks.fla file if you are using the Flash IDE and
the always-compile class if you are using the Flex SDK and Flash Develop. For any other
development tools, follow the documentation provided for that environment, to set a base, main,
or document class for your project.
Here's the folder structure for the Flash IDE:
/source/projects/notanks/flashIDE/com/efg/games/notanks/GameDemo.as
And this one is for the Flex SDK (using Flash Develop):
/source/projects/notanks/flexSDK/src/com/efg/games/notanks/GameDemo.as
Here is the first iteration of the entire GameDemo.as class. We will add to this class in following
sections. Type the following code into the file and save it; we will discuss the code in the next
section:
package com.efg.games.notanks
{
import flash.display.Sprite;
