爲基於文本的RPG創建更一致，隨機生成的世界空間

Question

目前，我可以在二維數組中創建一個隨機世界。不過，我覺得這太隨意了。這是我目前正與類：

from random import randint, choice, randrange

class WorldSpace(object): 
    def __init__(self, row, col, world_array): 
     self.row = row # Number of lists to be created. 
     self.col = col # Number of indexes inside of each row. 
     self.world_array = world_array 

創建世界上WorldSpace方法：

@classmethod 
def generate(cls, autogen): 
    print 'Starting world generation...' 
    print 
    if autogen is True: 
     row_amt = 75 
     col_amt = 75 

    else: 
     row_amt = input('Please specify row length of world array.: ') 
     col_amt = input('Please specify column length of world array.: ') 
     if (row_amt or col_amt) == 0: 
      print 'Invalid world values!' 
      cls.generateWorld(False) 

    world_array = [[' ']*col_amt for _ in xrange(row_amt)] 
    print 'Created world...' 

    return cls(row_amt, col_amt, world_array) 

修改該世界的方法 - 目前只創建forests儘管在我的全部代碼中，也形成了一系列的海洋和山脈：

def modify_world(self, autogen): 
    if autogen is True: 
     # Forests: 
     count = randint(6, 10) 
     while count > 0: 
      a = randint(1, (self.row/randint(2, 6))) 
      b = randint(1, (self.col/randint(2, 6))) 
      row_val = randint(5, self.row) 
      count_val = randint(5, 15) 
      self.genLine_WObj(a, b, row_val, 't', count_val) 
      count -=1 

    print('\n'.join([''.join(['{:1}'.format(item) for item in row]) 
     for row in self.world_array])) 
    inp = input('') 
    if inp != '': 
     return 

而實際創建forest磚的方法：

def genLine_WObj(self, a, b, row_val, char, count): 
    # 'genLine_WObj' - Generate Line(like) world object. 
    # Used to place lines of certain characters with psuedo-randomized 
    # width and length onto the world array. 
    while count != 0: 
     row_col_dict = {row_val: (a, b)} 
     for row in row_col_dict.keys(): 
      startPos, endPos = row_col_dict[row] 

      for i in range(startPos, endPos): 
       self.world_array[row][i] = char 

     b += choice([0, 1]) 
     a += choice([0, 0, 0, 0, 1]) 

     row_val -= 1 
     count -= 1 

現在實際運行程序：

world = WorldSpace.generate(True) 
world.modify_world(True) 

然而，雖然作品時〜20％-30％，有時當它應該在地圖周圍創建森林時，會生成小森林或小對t個字符。我如何改進我的代碼以使隨機生成的代更加一致？

修正：

1. 有時候你a是大於不產生你的b和森林。
2. 您的所有森林都傾向於位於地圖的左側。

爲更改的行添加內嵌註釋。

def modify_world(self, autogen): 
    if autogen is True: 
     # Forests: 
     count = randint(6, 10) 
     while count > 0: 
      a = randrange(self.col)   # begin of forest 
      width = self.col/randint(2, 6) # initial width of forest 
      b = int(a + width)    # end of forest 
      row_val = randint(5, self.row) 
      count_val = randint(5, 15) 
      self.genLine_WObj(a, b, row_val, 't', count_val) 
      count -=1 

    print('\n'.join([''.join(['{:1}'.format(item) for item in row]) 
     for row in self.world_array])) 
    inp = input('') 
    if inp != '': 
     return 


def genLine_WObj(self, a, b, row_val, char, count): 
    # 'genLine_WObj' - Generate Line(like) world object. 
    # Used to place lines of certain characters with psuedo-randomized 
    # width and length onto the world array. 
    while count != 0: 
     row_col_dict = {row_val: (a, b)} 
     for row in row_col_dict.keys(): 
      startPos, endPos = row_col_dict[row] 

      for i in range(startPos, min(self.col, endPos)): # added min 
       self.world_array[row][i] = char 

     b += choice([0, 1]) 
     a += choice([0, 0, 0, 0, 1]) 

     row_val -= 1 
     count -= 1 

而且我會將森林的width更改爲與地圖無關的東西。例如：

width = randint(2, 15) 

但這取決於你的目標。
