C# Class GameStateManagement.GameScreen

A screen is a single layer that has update and draw logic, and which can be combined with other layers to build up a complex menu system. For instance the main menu, the options menu, the "are you sure you want to quit" message box, and the main game itself are all implemented as screens.

Public Methods

Method Description
Draw ( GameTime gameTime ) : void

This is called when the screen should draw itself.

ExitScreen ( ) : void

Tells the screen to go away. Unlike ScreenManager.RemoveScreen, which instantly kills the screen, this method respects the transition timings and will give the screen a chance to gradually transition off.

HandleInput ( InputState input ) : void

Allows the screen to handle user input. Unlike Update, this method is only called when the screen is active, and not when some other screen has taken the focus.

LoadContent ( ) : void

Load graphics content for the screen.

UnloadContent ( ) : void

Unload content for the screen.

Update ( GameTime gameTime, bool otherScreenHasFocus, bool coveredByOtherScreen ) : void

Allows the screen to run logic, such as updating the transition position. Unlike HandleInput, this method is called regardless of whether the screen is active, hidden, or in the middle of a transition.

Private Methods

UpdateTransition ( GameTime gameTime, System.TimeSpan time, int direction ) : bool
