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……)

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

我用这种方法解决了一般关卡的这个问题:在关卡开始前，我从怪物洞中进行某种“洪水填充”;迷宫中除了墙之外的每一块瓦都有一个数字，表示它离洞有多远。所以当眼睛盯着一个距离为68的瓦片时，他们会看哪个相邻的瓦片距离为67;那就这么办吧。

在游戏开始前保存地图上的节点(交叉点) 当怪物死亡时，取点(坐标)并找到 节点列表中最近的节点 计算从该节点到洞的所有路径 按长度取最短路径 将该点与最近节点之间的空间长度相加 绘制并在路径上移动

享受吧!

实际上，我想说你的方法是一个非常棒的解决方案，与任何类型的寻径相比，运行时间成本几乎为零。

如果你需要将其推广到任意地图，你可以使用任何寻径算法——例如，宽度优先搜索很容易实现——并在游戏运行前使用该算法计算在每个角落编码的方向。

编辑(2010年8月11日):我刚刚看到了关于吃豆人系统的一个非常详细的页面:the Pac-Man Dossier，既然我已经得到了公认的答案，我觉得我应该更新它。这篇文章似乎没有明确地涉及回到怪物房子的行为，但它指出了《吃豆人》中的直接寻路是以下情况:

继续向下一个路口移动(尽管这本质上是一种特殊情况，即“当有选择时，选择不涉及反转方向的方向，如下一步所示); 在十字路口，看看相邻的出口方块，除了你刚刚出来的那个; 选一个离目标最近的。如果有多个方向同样接近目标，则按以下顺序选择第一个有效方向:上、左、下、右。

最初的《吃豆人》并没有使用寻径或花哨的AI。它只是让玩家觉得游戏比实际更有深度，但实际上它是随机的。正如Ian Millington和John Funge在《ai Intelligence for Games》中所述。

Not sure if it's true or not, but it makes a lot of sense to me. Honestly, I don't see these behaviors that people are talking about. Red/Blinky for ex is not following the player at all times, as they say. Nobody seems to be consistently following the player, on purpose. The chance that they will follow you looks random to me. And it's just very tempting to see behavior in randomness, especially when the chances of getting chased are very high, with 4 enemies and very limited turning options, in a small space. At least in its initial implementation, the game was extremely simple. Check out the book, it's in one of the first chapters.
