Main

The Main class (thelaststand.preloader.core/Main.as) is the entry point for the preloader of The Last Stand: Dead Zone. It is responsible for initializing the loading screen, managing the loading of core game assets, and preparing the environment before the main game (core.swf) is launched.

Sequential flow

• The Main class constructor sets up the stage properties and adds listeners for when the preloader is added or removed from the stage.
• When the preloader is added to the stage (onAddedToStage), it reads configuration parameters from loaderInfo (such as local, path, core, and useSSL) and calls init().
• The init() method:
  • Sets the static stage reference.
  • If available, enables JavaScript-Flash communication and registers a screenshot callback.
  • Instantiates the PlayerIOConnector and sets up event listeners for connection events.
  • Sets the secure API flag if needed.
  • Initializes loaders for the core game and background image, and attaches progress and completion listeners.
  • Begins loading the background image.
• When the background image finishes loading (onBackgroundLoadComplete or onBackgroundLoadFailed), initStage() is called to:
  • Add the background, logo (if needed), noise overlay, progress bar, spinner, and status text to the stage.
  • Notify JavaScript that the preloader is ready.
  • Animate the background and schedule the PlayerIO connection.
• When the PlayerIO connection completes (onPlayerIOConnected), loadCore() is called to:
  • Build the URL for the core SWF, set security permissions, and start loading the core game file.
  • Update the status text and loader context.
  • Validate the origin of the loaded file.
• As the core SWF loads, onCoreLoadProgress updates the progress bar.
• When the core SWF finishes loading (onCoreLoadComplete), initCore():
  • Adds the core game to the stage.
  • Cleans up preloader UI elements and listeners.
  • The core SWF file starts its Main class
• The class also handles stage resizing, spinner animation, connection errors, and provides a JavaScript-accessible screenshot function.
