In this exercise, you need to translate some rules from the classic game Pac-Man into Elixir functions.
You have four rules to translate, all related to the game states.
Don't worry about how the parameters are derived, just focus on combining the parameters to return the intended result.
Define the Rules.eat_ghost?/2
function that takes two parameters (if Pac-Man has a power pellet active and if Pac-Man is touching a ghost) and returns a boolean value if Pac-Man is able to eat the ghost. The function should return true only if Pac-Man has a power pellet active and is touching a ghost.
Rules.eat_ghost?(false, true)
# => false
Define the Rules.score?/2
function that takes two parameters (if Pac-Man is touching a power pellet and if Pac-Man is touching a dot) and returns a boolean value if Pac-Man scored. The function should return true if Pac-Man is touching a power pellet or a dot.
Rules.score?(true, true)
# => true
Define the Rules.lose?/2
function that takes two parameters (if Pac-Man has a power pellet active and if Pac-Man is touching a ghost) and returns a boolean value if Pac-Man loses. The function should return true if Pac-Man is touching a ghost and does not have a power pellet active.
Rules.lose?(false, true)
# => true
Define the Rules.win?/3
function that takes three parameters (if Pac-Man has eaten all of the dots, if Pac-Man has a power pellet active, and if Pac-Man is touching a ghost) and returns a boolean value if Pac-Man wins. The function should return true if Pac-Man has eaten all of the dots and has not lost based on the parameters defined in part 3.
Rules.win?(false, true, false)
# => false
