2D Python 游戏 map 移动后更新

Question

我目前正在开发使用文本作为 python 中的纹理的 2D 游戏。 这个游戏的主要思想是收集宝藏并试图逃离幽灵又名怪物。 经过一番努力，我终于为玩家和怪物添加了移动系统。 一切都在正常工作，因为坐标正在正确更改（函数 info() 将显示它们），但是我的 map 没有更新，我不知道如何更新它。

Map 为 12x12

#map generation

map_width = 12
map_height = 12
player_view = 1
map = [([1] * map_width)] + ([([1] + ([0] * (map_width - 2)) + [1]) for _ in range(map_height - 2)]) + [([1] * map_width)]
def print_map():
  for row in map:
    print(*row, sep='\t')
    print("\n")

生成玩家、怪物和宝藏等“对象”。 在玩家一代期间，将会有一代人的愿景。

#player generation + vision
    
  player = {
      "x_p":random.randint(1,map_width  - 2),
      "y_p":random.randint(1,map_height - 2),
      
  }
  map[player["y_p"]][player["x_p"]] = ‘😑’
  for i,row in enumerate(map[player["y_p"]- player_view :player["y_p"]+1 + player_view]):
    for j,element in enumerate(row[player["x_p"]- player_view :player["x_p"]+1 + player_view]):
      if (element == 0):
        map[player["y_p"] - player_view + i][player["x_p"] - player_view +j]='🕯'

#monster generation

  monster = {
      'y_m':random.randint(1, map_width - 2),
  }
  possible_x = []
  for i,e in enumerate(map[monster['y_m']]):
    if e == 0:
      possible_x.append(i)
  monster['x_m'] = random.choice(possible_x)
  map[monster["y_m"]][monster["x_m"]]='👻'

#treasure generation

  treasure = {
      'y_t':random.randint(1, map_width - 2),
  }
  possible_x = []
  for i,e in enumerate(map[treasure['y_t']]):
    if e == 0:
      possible_x.append(i)
  treasure['x_t'] = random.choice(possible_x)
  map[treasure["y_t"]][treasure["x_t"]]='💰'

程序中使用的所有函数

#printing info about characters, map dimensions and icons used

def info():
    print('\n')
    #print_map()
    #print('\n')
    print('Map dimentions are',map_width, 'x', map_height, '(including walls!)\n')
    print('Player -',player, 'Icon used:',player_character, '\n')
    print('Monster -',monster, 'Icon used: 👻.\n')
    print('Treasure -',treasure, 'Icon used: 💰.\n')
    print('Player vision value is', player_view,', and is represented with icon: 🕯.\n')
    print('Other icons used, 0 as empty area and 1 as walls. \n')

#generating number 1 or -1 randomly in order to select direction of monster movement

def monster_random_values():
  exclude = [0]
  movement_value = random.randint(-1,1)
  return my_custom_random() if movement_value in exclude else movement_value

最后是玩家和怪物的移动系统

loop = True
while loop:

    # movment system
    movment_choice = input('Please select your movment choice - [W,A,S,D]\nIf you want to exit press [Q]\n')
    if movment_choice == 'W' or movment_choice == 'w':
        print_map()
        player['y_p'] = (player['y_p'] + 1)
        #print(map[player['y_p']])
        info()
    elif movment_choice == 'A' or movment_choice == 'a':
        player['x_p'] = (player['x_p'] - 1)
        #print(map[player['x_p']])
        info()
    elif movment_choice == 'S' or movment_choice == 's':
        player['y_p'] = (player['y_p'] - 1)
        #print(map[player['y_p']])
        info()
    elif movment_choice == 'D' or movment_choice == 'd':
        player['x_p'] = (player['x_p'] + 1)
        #print(player['x_p'])
        info()
    elif movment_choice == 'Q':
      print('Thank you for playing the game!\n See you soon!')
      loop = False
    else:
        print('ERROR! Please select one of the options in the question')

    #monster movment
    possible_movment = random.randint(1, 3)
    if possible_movment == 1:
      monster['y_m'] = (monster['y_m'] + monster_random_values())
      monster['x_m'] = (monster['x_m'] + monster_random_values())
    elif possible_movment == 2:
      monster['y_m'] = (monster['y_m'] + monster_random_values())
    elif possible_movment == 3:
      monster['x_m'] = (monster['x_m'] + monster_random_values())
      info()

我希望这很清楚。 如果它不能正常工作，我将发送一个完整版本的代码。

谢谢你的帮助！

Answer 1

首先， map是内置的 python。 建议不要将其用作变量名。

其次，我会让 map 创建一个 function 并使用它返回的 object。

这是使用游戏 map 的set和程序生成的示例代码。 使用集合操作，我们将防止它们与 map 中的对象重叠。 我将使用tuple作为职位。

import random
BORDER = '1'

def create_map(map_width, map_height, num_treasures=1):
    locations = set((i, j) for i in range(map_height) for j in range(map_width))  # All available board coordinates
    player = (random.randint(1, map_width - 2), random.randint(1, map_height - 2))  # Player position
    locations = locations.difference({player})  # Remove player position from available positions
    border = ({(0, i) for i in range(map_width)}.union({(map_height - 1, i) for i in range(map_width)})).union(
        {(i, 0) for i in range(map_height)}.union({(i, map_height - 1) for i in range(map_height)}))  # All borders
    locations = locations.difference(border)  # Remove border from available locations
    vision = {(player[0] + dx, player[1] + dy) for dx in [-1, 0, 1] for dy in [-1, 0, 1]}.intersection(
        locations)  # 3 x 3 vision box. Player is not used since its location is not available in locations
    monster = random.choice(list(locations))  # Monster location selected randomly from available locations
    locations = locations.difference({monster})  # Remove monster from available locations
    treasures = set([])  # Do the same thing as monster with treasures in a loop
    for i in range(num_treasures):
        treasure = random.choice(list(locations))
        treasures.add(treasure)
        locations.remove(treasure)
    my_map = list(list([0] * map_width) for _ in range(map_height))  # Empty map
    my_map[player[0]][player[1]] = '😑'  # Set player
    my_map[monster[0]][monster[1]] = '👻'  # Set monster
    for x, y in border:  # Set border
        my_map[x][y] = BORDER
    for x, y in vision:  # Set vision
        my_map[x][y] = '🕯'
    for x, y in treasures:  # Set treasures
        my_map[x][y] = '💰'
    return my_map, player, monster, treasures

最后，我没有看到游戏while循环中发生任何更新。 您可以使用另一个 function 来执行此操作。

def move(my_map, player, player_move):
    # Legal move inputs
    if player_move in ['a', 'A']:  
        player_move = (0, -1)
        vision_remove = [(-1, 1), (0, 1), (1, 1)]
    elif player_move in ['w', 'W']:
        player_move = (-1, 0)
        vision_remove = [(1, -1), (1, 0), (1, 1)]
    elif player_move in ['d', 'D']:
        player_move = (0, 1)
        vision_remove = [(-1, -1), (0, -1), (1, -1)]
    elif player_move in ['s', 'S']:
        player_move = (1, 0)
        vision_remove = [(-1, -1), (-1, 0), (-1, 1)]
    else:
        return False, my_map, player
    neighbors = [(-1, -1), (-1, 0), (-1, 1), (0, -1), (0, 1), (1, -1), (1, 0), (1, 1)]
    # New position
    x = player[0] + player_move[0]
    y = player[1] + player_move[1]
    if my_map[x][y] != BORDER:  # Can't move into borders
        my_map[player[0]][player[1]] = 0
        my_map[x][y] = '😑'
        # Update vision while keeping treasure, ghost, border icons
        for dx, dy in vision_remove:  # Remove old vision
            value = my_map[player[0] + dx][player[1] + dy]
            my_map[player[0] + dx][player[1] + dy] = 0 if value == '🕯' else value
        for dx, dy in neighbors:  # Add new vision
            value = my_map[x + dx][y + dy]
            my_map[x + dx][y + dy] = '🕯' if value == 0 else value
        return True, my_map, (x, y)
    return False, my_map, player

一些辅助函数：

def to_string(my_map):
    return '\n'.join('\t'.join(str(x) for x in y) for y in my_map)


def print_map(my_map):
    print(to_string(my_map))

function这一招没有检测到捡宝，照样走鬼。 这些需要添加。

主循环看起来像这样：

my_map, player, monster, treasures = create_map(12, 12, 3)
updated = True
while True:
    # movement system
    if updated:
        updated = False
        print_map(my_map)
    movement_choice = input('Please select your movment choice - [W,A,S,D]\nIf you want to exit press [Q]\n')
    if movement_choice in ['q', 'Q']:
        print('Thank you for playing the game!\n See you soon!')
        break
    if movement_choice not in ['w', 'W', 'a', 'A', 's', 'S', 'd', 'D']:
        print('ERROR! Please select one of the options in the question')
    updated, my_map, player = move(my_map, player, movement_choice)
    hit, my_map, monster = move_monster(my_map, monster)
    if hit:
        print('Oh no! The monster got you.')
        print_map(my_map)
        break
