这个问题实际上有两个部分。生成棋盘状态,然后检查它是否正确。我意识到,检查正确性实际上比确保总是生成正确状态更糟糕。这就是我所做的:
请注意,我已经定义self.WallSpaces
为一个数组,长度与我的数组高度相等,由整数组成,位数等于我的数组宽度。self.Width
和self.Height
提供了数组的结束索引。基本上,Intersects
通过检查点周围的所有空间是否为1(除了“从中建造”的方向之外)来工作,并返回True
,如果它们中的任何一个是数组的边缘或1。
def Intersects(self, point, direction):
if (point[0] > 0):
if (direction != [1, 0] and self.WallSpaces[point[0] - 1] & (1 << point[1]) != 0):
return True
if (point[1] == 0 or self.WallSpaces[point[0] - 1] & (1 << (point[1] - 1)) != 0):
return True
if (point[1] == self.Width or self.WallSpaces[point[0] - 1] & (1 << (point[1] + 1)) != 0):
return True
else:
return True
if (point[0] < self.Height):
if (direction != [-1, 0] and self.WallSpaces[point[0] + 1] & (1 << point[1]) != 0):
return True
if (point[1] == 0 or self.WallSpaces[point[0] + 1] & (1 << (point[1] - 1)) != 0):
return True
if (point[1] == self.Width or self.WallSpaces[point[0] + 1] & (1 << (point[1] + 1)) != 0):
return True
else:
return True
if (point[1] == 0 or (direction != [0, 1] and self.WallSpaces[ point[0] ] & (1 << (point[1] - 1)) != 0)):
return True
if (point[1] == self.Width or (direction != [0, -1] and self.WallSpaces[ point[0] ] & (1 << (point[1] + 1)) != 0)):
return True
return False
GPacW.Left
、GPacW.Right
、GPackW.Up
和 GPacW.Down
表示移动的基本方向。该函数通过在数组中从随机点构造“墙壁”来实现功能,这些墙壁可以随机转向,并在相交两次时结束。
