下面是ammoQ的洪水填充想法的模拟和伪代码。

queue q
enqueue q, ghost_origin
set visited

while q has squares
   p <= dequeue q
   for each square s adjacent to p
      if ( s not in visited ) then
         add s to visited
         s.returndirection <= direction from s to p
         enqueue q, s
      end if
   next
 next

它的思想是宽度优先搜索，所以每次你遇到一个新的相邻正方形s，最好的路径是经过p。我相信是O(N)。

《吃豆人》中的幽灵遵循或多或少可预测的模式，即尝试先匹配X或Y，直到实现目标。我一直认为这对于眼睛寻找回去的路是完全一样的。

任何简单、可维护、可靠、性能足够好的解决方案都是好的解决方案。听起来你已经找到了一个很好的解决办法。

寻径解决方案可能比当前解决方案更复杂，因此更可能需要调试。它可能也会变慢。

在我看来，如果它没坏，就不要修。

EDIT

在我看来，如果迷宫是固定的，那么你当前的解决方案就是好的/优雅的代码。不要错误地把“好”或“优雅”等同于“聪明”。简单的代码也可以是“好的”和“优雅的”。

如果你有可配置的迷宫级别，那么也许你应该在最初配置迷宫时进行寻路。最简单的方法就是让迷宫设计师亲自动手。如果你有无数个迷宫，我才会费心自动化这个……或者用户可以自行设计。

(另外:如果路线是手工配置的，那么迷宫设计师可以通过使用次优路线来让关卡变得更有趣……)

假设你已经有了追逐吃豆人所需的逻辑，为什么不重用它呢?只要改变目标。这似乎比尝试使用完全相同的逻辑创建一个全新的例程要少得多。

我不太清楚你是如何执行游戏的，但你可以这么做:

Determine the eyes location relative position to the gate. i.e. Is it left above? Right below? Then move the eyes opposite one of the two directions (such as make it move left if it is right of the gate, and below the gate) and check if there are and walls preventing you from doing so. If there are walls preventing you from doing so then make it move opposite the other direction (for example, if the coordinates of the eyes relative to the pin is right north and it was currently moving left but there is a wall in the way make it move south. Remember to keep checking each time to move to keep checking where the eyes are in relative to the gate and check to see when there is no latitudinal coordinate. i.e. it is only above the gate. In the case it is only above the gate move down if there is a wall, move either left or right and keep doing this number 1 - 4 until the eyes are in the den. I've never seen a dead end in Pacman this code will not account for dead ends. Also, I have included a solution to when the eyes would "wobble" between a wall that spans across the origin in my pseudocode.

一些伪代码:

   x = getRelativeOppositeLatitudinalCoord()
   y
   origX = x
    while(eyesNotInPen())
       x = getRelativeOppositeLatitudinalCoordofGate()
       y = getRelativeOppositeLongitudinalCoordofGate()
       if (getRelativeOppositeLatitudinalCoordofGate() == 0 && move(y) == false/*assume zero is neither left or right of the the gate and false means wall is in the way */)
            while (move(y) == false)
                 move(origX)
                 x = getRelativeOppositeLatitudinalCoordofGate()
        else if (move(x) == false) {
            move(y)
    endWhile

我建议幽灵存储他从洞到吃豆人的路径。所以一旦鬼魂死了，他就可以沿着这条存储路径向相反的方向移动。
