第一个问题！ NPC 步行周期随机化器按预期工作（边界确实需要调整），但不播放嵌套的步行动画？ (AS3)

Question

差不多，我认为行走动画不能与 switch 语句一起使用？这就是它的样子，但随机发生器本身工作正常。我想做的是重写 mc 的工作代码，但是用 switch 语句中的案例（选择的随机行走方向）替换关键输入，并将重写的代码分别插入 NPC 的大脑（roshi）。

我设置代码的方式是 NPC "roshi" 是舞台上的电影片段。里面是单独的动画片段，每个动画片段都有每个行走动画的帧，但它们不会播放（例如 roshiRightStand、roshiRightWalk 等）。它总是卡在选定的帧上，无论我如何弄乱代码、括号或布尔值，它都不会真正进入动画片段。也许我没有声明或嵌套一些正确的东西或根本没有？动画是嵌套在另一个动画片段中的动画片段中的帧，名称似乎与属性匹配？不太确定如何声明它，但在某些时候我相信我可能已经让整个事情正常进行并把它搞砸了。如果有帮助，请留下我的旧剩余代码？任何输入将不胜感激！学习还算快。 :)

Answer 1

好吧，我们还是试试吧。将其与 Roshi 图形一起放入单独的项目中。您的代码与此代码之间的主要区别是我不会在每一帧触发 Roshi.gotoAndStop，仅在 Roshi 改变方向时触发一次。

// Integers, because you don't have to round them.
var roshiTimer:int = 0;
var roshiDuration:int = 0;
var roshiFacing:int = 0;
var roshiSpeed:Number = 3;

addEventListener(Event.ENTER_FRAME, onRoshi);

// Let's do this instead of switch.
var RF:Array = [
    "roshiUpWalk", "roshiDownWalk",
    "roshiLeftWalk", "roshiRightWalk",
];

var RX:Array = [0, 0, -1, 1];
var RY:Array = [-1, 1, 0, 0];

function onRoshi(e:Event):void
{
    roshiTimer++;

    if (roshiTimer > roshiDuration)
    {
        roshiDuration = 10 + Math.random() * 25;
        roshiTimer = 0;

        // Let's make Roshi ALWAYS change direction
        // without occasionally proceeding to the same one.
        while (Roshi.currentLabel == RF[roshiFacing])
        {
            roshiFacing = Math.random() * 4;
        }

        Roshi.gotoAndStop(RF[roshiFacing]);
    }

    Roshi.x += RX[roshiFacing] * roshiSpeed;
    Roshi.y += RY[roshiFacing] * roshiSpeed;
}
