C# Class FarseerPhysics.Samples.ScreenSystem.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.
GameScreen ( ) : System
HandleInput ( InputHelper input, GameTime gameTime ) : 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
