如何以某种方式移动角色？

Question

有办法。角色从中点开始。如果HorizontalAxis > 0，它应该向右移动，如果< 0，它应该向左移动。我做过这样的事情-

方式：

public Transform[] PatrolPoints;
public Transform Way;
public int CurrentPoint;
public int NeedPoint;

if (transform.position == PatrolPoints[CurrentPoint].position && CurrentPoint < PatrolPoints.Length-1) 
{
    //PatrolPoints[CurrentPoint];
    NeedPoint = CurrentPoint + 1;
}       
else if(transform.position == PatrolPoints[NeedPoint].position && CurrentPoint != PatrolPoints.Length - 1)
{
    CurrentPoint++;
}
else if(transform.position == PatrolPoints[PatrolPoints.Length - 1].position)
{
    NeedPoint--;
}
if (CurrentPoint != PatrolPoints.Length - 1 && moveAxis > 0)
{
    transform.position = Vector3.MoveTowards(transform.position, PatrolPoints[NeedPoint].position, moveAxis * moveRate * Time.deltaTime);
    //An error occurs here
}
    else if(CurrentPoint > 0 && moveAxis < 0)
{
    transform.position = Vector3.MoveTowards(transform.position, PatrolPoints[NeedPoint - 1].position, -moveAxis * moveRate * Time.deltaTime);
}

数组的长度 - 3 个元素。 从中间点到右边，人物一般都是左右走的，但是一到最后一点，就报错了——

数组索引超出范围

期间的错误变量是：

需要点：-1；

当前点：2；

而且从中间到左边，角色根本不走。

这是解决方案：

字符从中点开始。然后它应该移动到 如果 Horizo​​ntalAxis > 0，则向右，如果

我假设“向右移动”意味着增加数组中的索引，而“向左移动”意味着减少数组中的索引

public Transform[] PatrolPoints;
public int NextPointOnLeft = 0; // because player starts at 1
public int NextPointOnRight = 2; // because player starts at 1

if (HorizontalAxis < 0)
{
    if (transform.position == PatrolPoints[NextPointOnLeft].position)
    {
        if(NextPointOnLeft > 0)
        {
            --NextPointOnLeft;
        }
        // EDIT: NextPointOnRight = NextPointOnLeft + 1;
    }
    // EDIT:
    NextPointOnRight = NextPointOnLeft + 1;
    transform.position = Vector3.MoveTowards(transform.position, PatrolPoints[NextPointOnLeft].position, moveRate * Time.deltaTime);
}
if (HorizontalAxis > 0)
{
    if (transform.position == PatrolPoints[NextPointOnRight].position)
    {
        if(NextPointOnRight < PatrolPoints.Length-1)
        {
            ++NextPointOnRight;
        }
        // EDIT: NextPointOnLeft = NextPointOnRight - 1;
    }
    // EDIT:
    NextPointOnLeft = NextPointOnRight - 1;
    transform.position = Vector3.MoveTowards(transform.position, PatrolPoints[NextPointOnRight].position, moveRate * Time.deltaTime);
}
