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:
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.
The
IStateBase
interface requires that each State class have the ShowIt()
method. The ShowIt()
method will also be called from the StateManager
. It's time to connect this method with the StateManager
code.
The StateManager
class needs to have Unity's OnGUI()
method. Just the way the UpDate()
method transfers control to the StateUpdate()
method on the active State, the OnGUI()
method transfers control to the ShowIt()
method on the active State as well.
