GameFS

GameFS is used to store and distribute game files to players. TLSDZ access GameFS through the PlayerIO client library.

// preloader/thelaststand.preloader.core.Main@line 114
PlayerIO.gameFS("dev-the-last-stand-iret8ormbeshajyk6woewg").getUrl(this._rootPath + "preloader.swf",this._useSSL)

This call instantiates the GameFS class with gameId of “dev-the-last-stand-iret8ormbeshajyk6woewg”. Once it is constructed, the getUrl method allows the game client to request a specific file path and get back a full URL that can be downloaded.

The getUrl method takes two arguments: a path string like /game/data/preloader.swf, and an optional secure boolean. If secure is true, the returned URL uses HTTPS; otherwise, it uses HTTP.

Internally, a URLMap processing happens. It is not known what it try to achieve. The full URL processing is simply:

// playerio.GameFS@line 31
return (param3 ? "https" : "http") + "://127.0.0.1:8080/r/" + param1 + param2;
  • param3 should be the secure flag.
  • The string is TLSDZ domain name. In this case, we should replace it to our domain (e.g., 127.0.0.1).
  • param1 is the gameId. See gameId
  • param2 is a game file path. The GameFS enforce file path to start with a slash (/).

It will produce a URL like http://127.0.0.1:8080/r/dev-the-last-stand-iret8ormbeshajyk6woewg/preloader.swf.
