Question

import  numpy as np
import itertools as it
x=[1,2,3,4,5,6,7,8,9]
def moving_window(x, length, step=1):
    streams = it.tee(x, length)
    return zip(*[it.islice(stream, i, None, step) for stream, i in zip(streams, it.count(step=step))])
x_=list(moving_window(x, 3))
x_=np.asarray(x_)
print(x_)

问题是，例如，当转换到达targetPos时，变换在开始时的高度为200，它的高度为0。

但是我希望它能够在相同的高度上到达它上面的targetPos而不是高度0.当它到达targetPos它会做什么并不重要但是我想要的是它会在同一个地方到达身高。

这是完整的脚本：

bool flying = false; // shows when FlyTo is running
                         // coroutine that moves to the specified point:
    IEnumerator FlyTo(Vector3 targetPos)
    {
        flying = true; // flying is true while moving to the target
        Vector3 startPos = transform.position;
        Vector3 dir = targetPos - startPos;
        float distTotal = dir.magnitude;
        dir /= distTotal; // normalize vector dir
                          // calculate accDist even for short distances
        float accDist = Mathf.Min(accDistance, distTotal / 2);
        do
        {
            float dist1 = Vector3.Distance(transform.position, startPos);
            float dist2 = distTotal - dist1;
            float speed = maxVel; // assume cruise speed
            if (dist1 < accDist)
            { // but if in acceleration range...
              // accelerate from startVel to maxVel
                speed = Mathf.Lerp(startVel, maxVel, dist1 / accDist);
            }
            else
            if (dist2 < accDist)
            { // or in deceleration range...
              // fall from maxVel to stopVel
                speed = Mathf.Lerp(stopVel, maxVel, dist2 / accDist);
            }
            // move according to current speed:
            transform.position = Vector3.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
            yield return 0; // let Unity breathe till next frame
        } while (transform.position != targetPos); // finish when target reached
        flying = false; // shows that flight has finished
    }

如我的评论中所述，不要两次更新位置，这会导致开销，通过在循环之前更改目标的Y坐标可以轻松避免。

 IEnumerator FlyTo(Vector3 targetPos)
    {
        flying = true; // flying is true while moving to the target
        Vector3 startPos = transform.position;

        //Insert this line right here.
        targetPos.y = startPos.y;
        Vector3 dir = targetPos - startPos;
        //The rest of your code remains the same...

在你的DO内找到这一行，靠近末尾并将其删除

       Vector3 pos = Vector3.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
    //pos.y = lastPos.y; ~ REMOVE THIS LINE~

假设Y是高度轴，也许是它的实际Z轴，试试看。

如何在移动时保持变换高度？
