C# Class NScumm.MonoGame.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.

This public class is similar to one in the GameStateManagement sample.

DrawRectangle ( Rectangle rectangle, Color color, BlendState blendState = null ) : void	Draw an empty rectangle of the given size and color.
EndRun ( ) : void
FadeBackBufferToBlack ( int alpha ) : void	Helper draws a translucent black fullscreen sprite, used for fading screens in and out, and for darkening the background behind popups.
GetScreens ( ) : NScumm.MonoGame.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.
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 ( Microsoft.Xna.Framework.Game game ) : System	Constructs a new screen manager component.
Update ( GameTime gameTime ) : void	Allows each screen to run logic.
