Arguments

:: GameMonad a	action to be executed
-> GameState	current state of the game
-> GameState	game state after the action

evaluate an action on a GameState and return new state

execStateWithUndo :: GameMonad a -> GameState -> GameState #

same as execState but save previous state for undo operations

get' :: GameMonad GameState #

get current GameState

for internal use only

getConfig :: GameMonad GameConfig #

get the GameConfig of the current state

getGlobalState :: GameMonad GlobalGameState #

get the GlobalGameState of the current state

getCells :: GameMonad CellStates #

get the CellStates of the current state

getCell :: BoardCoordinate -> GameMonad CellState #

get the CellState of the cell at given coordinate

setCell :: BoardCoordinate -> CellState -> GameMonad () #

update the CellState at the given coordinate

this will also automatically update the GlobalGameState
