Public Methods

Method	Description
InputState ( ) : Microsoft.Xna.Framework	Constructs a new input state.
IsMenuCancel ( PlayerIndex controllingPlayer, PlayerIndex &playerIndex ) : bool	Checks for a "menu cancel" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player. When the action is detected, the output playerIndex reports which player pressed it.
IsMenuDown ( PlayerIndex controllingPlayer ) : bool	Checks for a "menu down" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player.
IsMenuLeft ( PlayerIndex controllingPlayer ) : bool	Checks for a "menu left" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player.
IsMenuRight ( PlayerIndex controllingPlayer ) : bool	Checks for a "menu right" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player.
IsMenuSelect ( PlayerIndex controllingPlayer, PlayerIndex &playerIndex ) : bool	Checks for a "menu select" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player. When the action is detected, the output playerIndex reports which player pressed it.
IsMenuUp ( PlayerIndex controllingPlayer ) : bool	Checks for a "menu up" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player.
IsMouseMoved ( ) : bool	Helper for checking if the position of the mouse has changed during this update.
IsNewButtonPress ( Buttons button ) : bool	Helper for checking if a button was newly pressed during this update. This method is designed for use in one-player games and only checks the gamepad for player one.
IsNewButtonPress ( Buttons button, PlayerIndex controllingPlayer, PlayerIndex &playerIndex ) : bool	Helper for checking if a button was newly pressed during this update. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player. When a button press is detected, the output playerIndex reports which player pressed it.
IsNewKeyPress ( Keys key ) : bool	Helper for checking if a key was newly pressed during this update. This method is designed for use in PC games where there is only one keyboard.
IsNewKeyPress ( Keys key, PlayerIndex controllingPlayer, PlayerIndex &playerIndex ) : bool	Helper for checking if a key was newly pressed during this update. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player. When a keypress is detected, the output playerIndex reports which player pressed it.
IsNewMouseButtonPress ( MouseButtons button ) : bool	Helper for checking if a mouse button was newly pressed during this update. No controlling player parameter is required because there is only one mouse.
IsPauseGame ( PlayerIndex controllingPlayer ) : bool	Checks for a "pause the game" input action. The controllingPlayer parameter specifies which player to read input for. If this is null, it will accept input from any player.
Update ( ) : void	Reads the latest state of the keyboard and gamepad.
