Detailed Description

Allacrost initialization code and main game loop.

****************************************************************************

Author:

Tyler Olsen, roots@allacrost.org

The code in this file is the first to execute when the game is started and the last to execute before the game exits. The core engine of Allacrost uses time-based updating, which means that the state of the game is updated based on how much time has expired since the last update.

The main game loop consists of the following steps.

1. Render the newly drawn frame to the screen.
2. Collect information on new user input events.
3. Update the main loop timer.
4. Update the game status based on how much time expired from the last update.

void QuitAllacrost

(

)

Frees all data allocated by Allacrost by destroying the singleton classes.

Note:

Do not attempt to call or otherwise reference this function. It is for use in the application's main() function only.

Deleteing the singleton class objects will free all of the memory that the game uses. This is because all other classes and data structures in Allacrost are managed by these singletons either directly or in directly. For example, BattleMode is a class object that is managed by the GameModeManager class, and thus the GameModeManager destructor will also invoke the BattleMode destructor (as well as the destructors of any other game modes that exist).
