Ingame menu is not working correctly
- by Johnny
The ingame menu opens when the player presses Escape during the main game. If the player presses Y in the ingame menu, the game switches to the main menu. Up to here, everything works.
But:
On the other hand, if the player presses N in the ingame menu, the game should switch back to the main game(should resume the main game). But that doesn't work. The game just rests in the ingame menu if the player presses N.
I set a breakpoint in this line of the Ingamemenu class:
KeyboardState kbState = Keyboard.GetState();
CurrentSate/currentGameState and LastState/lastGameState have the same state: IngamemenuState.
But LastState/lastGameState should not have the same state than CurrentSate/currentGameState.
What is wrong? Why is the ingame menu not working correctly?
