Game.Update Method

Called when the game has determined that game logic needs to be processed. This might include the management of the game state, the processing of user input, or the updating of simulation data. Override this method with game-specific logic.

When updating the game state, you can examine SignedInGamer.GameDefaults to determine a player's preferences for settings such as game difficulty and controller sensitivity.

Update and Draw are called at different rates depending on whether IsFixedTimeStep is true or false. If IsFixedTimeStep is false, Update and Draw will be called in a continuous loop. If IsFixedTimeStep is true, Update will be called at the interval specified in TargetElapsedTime, while Draw will only be called if an Update is not due. If Draw is not called, IsRunningSlowly will be set to true.
