Time for action – modifying PlayState to add another State
We still don't have any game logic to call for State switching, so we'll just simulate being killed in the game by detecting when the Return/Enter key is pressed. Add another if statement in the StateUpdate() method of PlayState, as shown in the following screenshot:
What just happened?
That's it. That's all it takes to add another State. Simply call the SwitchState() method to instantiate any State class you wish.
The following is the Console output when you press Return/Enter while in PlayState:
What happens if you press the Return/Enter key while in any of the other States? Nothing, of course. There's no code for the Return/Enter key in the other States.
Note
This maybe a simple example, but it demonstrates how each State has its own controlling game code.
Adding OnGUI to the StateManager class
The
IStateBase interface requires that each State class have the ShowIt() method. The ShowIt() method will also be called from the StateManager...
