C# Class GameStateManagement.ScreenManager

The screen manager is a component which manages one or more GameScreen instances. It maintains a stack of screens, calls their Update and Draw methods at the appropriate times, and automatically routes input to the topmost active screen.

Public Methods

Method	Description
AddScreen ( GameScreen screen ) : void	Adds a new screen to the screen manager.
Draw ( GameTime gameTime ) : void	Tells each screen to draw itself.
FadeBackBufferToBlack ( float alpha ) : void	Helper draws a translucent black fullscreen sprite, used for fading screens in and out, and for darkening the background behind popups.
GetScreens ( ) : GameStateManagement.GameScreen[]	Expose an array holding all the screens. We return a copy rather than the real master list, because screens should only ever be added or removed using the AddScreen and RemoveScreen methods.
Initialize ( ) : void	Initializes the screen manager component.
LoadContent ( ) : void	Load your graphics content.
RemoveScreen ( GameScreen screen ) : void	Removes a screen from the screen manager. You should normally use GameScreen.ExitScreen instead of calling this directly, so the screen can gradually transition off rather than just being instantly removed.
ScreenManager ( LDEngine game ) : System	Constructs a new screen manager component.
TraceScreens ( ) : void	Prints a list of all the screens, for debugging.
UnloadContent ( ) : void	Unload your graphics content.
Update ( GameTime gameTime ) : void	Allows each screen to run logic.
