# Ghost Gobble Arcade Game
|
|
|
|
Welcome to Ghost Gobble Arcade Game on Exercism's Python Track.
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
|
If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :)
|
|
|
|
## Introduction
|
|
|
|
Python represents true and false values with the [`bool`][bools] type, which is a subtype of `int`.
|
|
There are only two values in this type: `True` and `False`.
|
|
These values can be bound to a variable:
|
|
|
|
```python
|
|
>>> true_variable = True
|
|
>>> false_variable = False
|
|
```
|
|
|
|
We can evaluate Boolean expressions using the `and`, `or`, and `not` operators:
|
|
|
|
```python
|
|
>>> true_variable = True and True
|
|
>>> false_variable = True and False
|
|
|
|
>>> true_variable = False or True
|
|
>>> false_variable = False or False
|
|
|
|
>>> true_variable = not False
|
|
>>> false_variable = not True
|
|
```

## Instructions
|
|
|
|
In this exercise, you need to implement some rules from [Pac-Man][Pac-Man], the classic 1980s-era arcade-game.
|
|
|
|
You have four rules to implement, all related to the game states.
|
|
|
|
> _Do not worry about how the arguments are derived, just focus on combining the arguments to return the intended result._
|
|
|
|
## 1. Define if Pac-Man eats a ghost
|
|
|
|
Define the `eat_ghost()` 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 a ghost.
|
|
The function should return `True` only if Pac-Man has a power pellet active and is touching a ghost.
|
|
|
|
```python
|
|
>>> eat_ghost(False, True)
|
|
...
|
|
False
|
|
```
|
|
|
|
## 2. Define if Pac-Man scores
|
|
|
|
Define the `score()` 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.
|
|
|
|
```python
|
|
>>> score(True, True)
|
|
...
|
|
True
|
|
```
|
|
|
|
## 3. Define if Pac-Man loses
|
|
|
|
Define the `lose()` 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.
|
|
|
|
```python
|
|
>>> lose(False, True)
|
|
...
|
|
True
|
|
```
|
|
|
|
## 4. Define if Pac-Man wins
|
|
|
|
Define the `win()` 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.
|
|
|
|
```python
|
|
>>> win(False, True, False)
|
|
...
|
|
False
|
|
```
