Description
Pokémon Gym Battle
Create a game where the user must defeat three pokémon to win the game. Use inheritance to
implement the following class diagram in your program.
Abstract Pokemon Class (pokemon.py) –
1. __init__(self, name, type) – set the _name, and _type using the parameters, assign the
_battle_table the 2D list given above, and set _hp to 25.
2. hp property – use a decorator to get (not set) the value of _hp.
3. get_normal_menu(self) – returns a string with the menu options for the normal moves:
slam and tackle.
4. _normal_move(self, opponent, move) – use the move parameter to choose to call either
slam or tackle method, returns the string returned from those methods.
5. _slam(self, opponent) and _tackle(self, opponent) – randomize some damage (slam 1-8,
tackle 3-6), call take_damage on the opponent and return a string description of the move
using both pokemons names, the type of move, and the amount of damage taken.
6. get_special_menu(self) – abstract (overridden in the subclasses) – returns the menu for
the special moves of each type.
7. _special_move(self, opponent, move) – abstract (overridden in the subclasses) – uses the
move parameter to choose to call either of the special moves for that type.
8. attack(self, opponent, type, move) – use the type parameter to choose to call either
_normal_move or _special_move.
9. __str__(self) – display the pokemon’s name and hp in the format “Name: hp/25”.
10. _take_damage(self, dmg) – the damage the pokemon takes. Subtract the dmg value from
the pokemon’s _hp. Check that the _hp doesn’t go past 0 (if it’s negative, reset it to 0).
Fire/Water/Grass Classes (fire.py/water.py/grass.py) – each inherit from Pokemon
1. __init__(self, name) – call super to set the name and type (fire = 0, water = 1, grass = 2).
2. Override the get_special_menu and _special_move methods for this class.
3. Create the two move methods – each pokemon type has two moves (listed above in the
class diagram). Randomize damage (move1 1-5, move2 3-4), look up the multiplier in
the battle table based on the two pokemon’s type and calculate the total damage the
opposing pokemon will take (make sure it’s a whole number, not a decimal). Then return
a string description of the move using both pokemons names, the type of move, the
amount of damage taken, and whether it was effective (2) or not (.5).
Main (main.py) – Choose a random type of pokemon that the gym leader will have (ie. fire,
water, or grass). Create a list of three pokemon objects all of the same type and give them
names. Prompt the user to choose a single pokemon of one of the three types. Allow the user to
choose what type of attack to do (ie. normal or special), and then which move to do of that type
(ie. if the user chose normal, then they can either choose slam or tackle), call the pokemon’s
attack method and display the resulting string.
If the gym leader’s pokemon still has hit points,
then it will choose a random type and move to attack back with. When one of the gym leader’s
pokemon is defeated, remove it from the list. Repeat until the user has defeated all three of the
gym leader’s pokemon, or until the user’s pokemon is defeated. Display a message when the
user wins/loses. Check all input for validity. Document all classes, methods, and functions.
Example Output (user input is in italics):

Notes:
1. You should have 5 different files: pokemon.py, fire.py, water.py, grass.py, and main.py.
2. Use docstrings to document each of the classes, their attributes, and each of their
methods. See the lecture notes for examples.
3. Place your names, date, and a brief description of your program in a comment block at
the top of your main file. Place brief comments throughout your code.
4. Do not create any extra attributes, methods, or parameters.
5. Please do not create any global variables or use the attributes globally. Use the methods
instead. You can use the attributes in the subclasses when needed. You can access the
hp in main using the property. Only use the public methods (non-underscored) in main.
6. Check all user input using the get_int_range function in the check_input module.
7. Feel free to add text to make the game more interesting and to add flair. You may also
modify the random amounts of damage to better balance the game.
8. List of pokemon names and types: https://pokemondb.net/pokedex/game/red-blue-yellow.
9. Thoroughly test your program before submitting:
a. Make sure that your classes are inherited properly. Fire, Water, and Grass should
inherit from Pokemon, and Pokemon should be abstract with two abstract methods.
b. Make sure user input is validated.
c. Make sure that each type of pokemon does the proper special attacks.
d. Make sure that the normal attacks do not use the multiplier from the battle table.
e. Make sure that the special attacks do use the multiplier from the battle table.
f. Make sure that the correct multiplier is used for the two types of pokemon (ie. Fire is
super effective against Grass, Water is super effective against Fire, and Grass is super
effective against Water).
g. Make sure that the damage dealt is correctly subtracted from the opponent.
h. Make sure that the defeated pokemon are removed from the list.
i. Make sure the game ends when the user defeats all 3 pokemon, or when the user’s
pokemon runs out of hp.
