I learned Python and Pygame and now have coded a few games. For the last few months I have been working on this "luck free" pokemon battle simulator. I feel my program runs well in the current state and at the same time is being semi spaghetti-coded because as I try to improve the game I find it more challenging than it should.

I know there are some things done wrong or improperly. Any constructive criticism you have to input is appreciated. There are multiple more files you can find here.

Here's the game.py file where the majority of the battle code is:

        else:
            opponent_move = computer_move.best_switch(pokemon, Game.Opponent_Party)
        test_move = computer_move.stay_alive(pokemon, opponent, Game.Opponent_Party)
        if test_move and not kill:
            opponent_move = test_move
        #return spikes
        return opponent_move

Are there better ways I could handle the moves and maybe make a turn() method? I plan on working on this project for a long time so I want to make it better. There are other Pokemon type battle questions out there but I feel this game is more complex than most.

  • if you use variable/attibute names like move1 or type2 it is almost always a sign that it wants to be a list (moves, types)

    sprites = [
        [pokemon.back_image, (225, 250)],
        [opponent.front_image, (475, 50)],
        [pokemon.type.image, (495, 265)],
        [opponent.type.image, (75, 40)],
    ]
if opponent.type2 != None:
    type2 = (opponent.type2.image, (107, 40))
    sprites.append(type2)
if pokemon.type2 != None:
    type2 = (pokemon.type2.image, (527, 265))
    sprites.append(type2)

    sprites = [
        [pokemon.back_image, (225, 250)],
        [opponent.front_image, (475, 50)],
    ]
for current_pokemon,locations in [
        (pokemon,[(495, 265),(527, 265)]),
        (opponent,[(75, 40),(107, 40)])
        ]:
    for type,location in zip(current_pokemon.types,locations):
        sprites.append([(type.image,location)]

  • use list literals, instead of:

    screens = []
screens.append(home_screen)
screens.append(team_builder_screen)
screens.append(play_screen)
screens.append(options_screen)
screens.append(gym_leaders_screen)

    use:

    screens = [
    home_screen,
    team_builder_screen,
    play_screen,
    options_screen,
    gym_leaders_screen
    ]

  • misleading variable name: next_move_text is actually an image

  • avoid repetition at almost all costs let the computer do the repetition
    repeated code makes it much harder to change/improve code
    whenever there are multiple lines after each other that are almost the same,
    you found a place to improve

    next_move_text = pygame.image.load('images/next_move.png')
next_pokemon_text = pygame.image.load('images/next_pokemon.png')
exit_text = pygame.image.load('images/exit_text.png')
continue_text = pygame.image.load('images/continue.png')
game_over_text = pygame.image.load('images/game_over.png')
text_bubbles = [next_move_text, next_pokemon_text, exit_text, continue_text, game_over_text]

    to

    image_filename_list = [
    'images/next_move.png',
    'images/next_pokemon.png',
    'images/exit_text.png',

    x_axis = 470
Lose, Win = True, True
Game.can_switch = False
for pokemon in Game.Pokemon_List:
    pokeball = [Pokemon.Pokeball, (x_axis, 334)]
    sprites.append(pokeball)

    return party_alive,can_switch

Lose, Game.can_switch = check_pokemon_party(

    )

  • dont use an index to remember the current_item but use the item itself (unneeded complexity):

    Game.current_pokemon_number = new_number

    to

    Game.current_pokemon = Game.Pokemon_List[new_number]

    Game.help_text_number = 3

    to

    Game.help_text = Game.text_bubbles[3]

  • using a dictionary instead of a list can make things much more readable:

    image_filename_list = [
'images/next_move.png',
'images/next_pokemon.png',
'images/exit_text.png',
'images/continue.png',
'images/game_over.png',
]
text_bubbles = [pygame.image.load(filename) for file_name in image_filename_list]
...
Game.help_text = Game.text_bubbles[3]

    image_names = ['next_move', 'next_pokemon', 'exit_text', 'continue', 'game_over']
text_bubbles = {
name: pygame.image.load('images/{}.png'.format(name)) for name in image_names
}
...
Game.help_text = Game.text_bubbles['exit_text']

  • use polymorphism instead of 'if' in some cases:

    if Game.current_screen_number == 2:
Game.update_info(screen)
elif Game.current_screen_number == 1:
Game.show_stats(screen)
elif Game.current_screen_number == 3:
Game.options(screen)
elif Game.current_screen_number == 4:
Game.Gym_Leaders(screen)

    to

    class InfoScreen():
def draw(game):
    #draw screen
class StatScreen():
def draw(game):
    #draw screen
...
Game.current_screen = InfoScreen()
Game.current_screen.draw(Game)

    def do_moves(move):
Game.pause = True
opponent_move = Game.opponent_move()
if not isinstance(move, int) and not isinstance(opponent_move, int):
    ....

    to

    class SwitchMove()
...
@property
def priority():
    return (0,0)
def do(game):
    # switch pokemon
class PokemonMove()
...
@property
def priority():
    return (1, self.pokemon.speed)
def do(game):
    # execute pokemon move
...
def do_moves(move):
moves = (move,Game.opponent_move())
moves = sorted(moves,key= lambda x: x.priority)
for move in moves:
    move.do(game)

  • convert comments into functions makes the block more explicit and less likely to become out of date:

    
'# Blitting the sprites
for item in info_sprites:
    screen.blit(item[0], item[1])
for item in secondary_info:
    Functions.text_to_screen(screen, item[0], item[1], item[2], 18)
for item in sprites:
    screen.blit(item[0], item[1])
    

    def blitting_the_sprites():
    for item in info_sprites:
        screen.blit(item[0], item[1])
    for item in secondary_info:
        Functions.text_to_screen(screen, item[0], item[1], item[2], 18)
    for item in sprites:
        screen.blit(item[0], item[1])
blitting_the_sprites()

  • extract repeating structure into subobjects(more consistently structured):

    Game.Pokemon_List
Game.current_pokemon
Game.Pokemon_Party

Game.Opponent_Pokemon_List
Game.opponent.pokemon
Game.Opponent_Party

    class Player():
    def __init__(self, pokemon_list, current_pokemon, pokemon_party):
        self.pokemon_list = pokemon_list
        self.current_pokemon = current_pokemon
        self.pokemon_party = pokemon_party

Game.player = Player(...)
Game.opponent = Player(...)

Game.player.pokemon_list
Game.player.current_pokemon
Game.player.pokemon_party

Game.opponent.pokemon_list
Game.opponent.current_pokemon
Game.opponent.pokemon_party

  • remove commented out code temporarily it is fine but it should last only about a day and should not be checked in because commented out code distracts from the other code

  • \$\begingroup\$ Thanks man this helps me a lot! I have never heard of the zip() function, I will have to test it out! Also the way you coded the text_bubbles blew my mind, I had no idea that I could do that! You covered so much and I'm sure there is more to be corrected. If I could ask you a quick question: in my [link] (github.com/fudgenuggets1/hax_free_pokemon/blob/master/…) bold 'yo_buttons.py' file under the do_action() method I think there should be a cleaner way to handle button actions. There is a lot of repetition there and I am not exactly sure of how to improve. Thanks again! \$\endgroup\$
