Initialize local variable NextState
Set NextState to CurrentState

Case Current State:
	
	Current State is MasterPseudoState
		if ThisEvent is ES_INIT
			NextState = Welcome
			FlipPolarBear down
		endif
	end MasterPseudoState block
	
	CurrentState is Welcome
		if ThisEvent is STARTBUTTON and LeafInserted==True
			NextState = Playing
			Start GameTimer to 60 seconds
			Start InactivityTimer to 30 seconds
			PostAll GAME_START event
	end Welcome block			
	
	CurrentState is Playing
		if ThisEvent is INACTIVITY_TIMER_TIMEOUT
			PostAll RESET event
			FlipPolarBear down
			Clear the GameTimer
			NextState = Welcome
		if ThisEvent is LEAF_REMOVED
			PostAll RESET event
			FlipPolarBear down
			Clear InactivityTimer
