Button Event Checker Pseudocode

Function InitButtonEventChecker():

- Initialize LastButtonState to the current state of the button (e.g., PORTBbits.RB2)

- Initialize LastTickCount to the current timer value using ES_Timer_GetTime()

Function Check4Button():

- Initialize ReturnVal to false (default: no event detected)

- Read the current state of the button into CurrentButtonState (e.g., PORTBbits.RB2)

- Declare an Event object ThisEvent

    If QueryGameFSM() returns Wait4Input:

     - Check if CurrentButtonState is different from LastButtonState:

            If CurrentButtonState indicates a button press (e.g., 0):

             - Print "Button Down"

             - Set ThisEvent.EventType to BUTTON_DOWN

             - Post ThisEvent to ButtonModule

             - Set ReturnVal to true (indicating an event was detected)

- Update LastButtonState to CurrentButtonState

- Return ReturnVal
