c# - Vector3.MoveTowards 没有做它的事情

Question

当我使用 Vector3.MoveTowards 方法时，木板无法移动。我不完全确定为什么。有好心人来看看吗？

public class BrickMoveVErtical : MonoBehaviour 
{
    public Vector3 positionOne, positiontwo, nextposition;
    public Transform plankTranform;
    public Transform positionBTransform;
    public float speed;

    void Start () 
    {
        positionOne  = plankTranform.localPosition;
        positiontwo  = positionBTransform.localPosition;
        nextposition = positiontwo;
    }

    void Update () 
    {
        move();
    }
    private void move() 
    {
       plankTranform.localPosition = Vector3.MoveTowards(positionOne,nextposition,Time.deltaTime*speed);
       if(Vector3.Distance(plankTranform.localPosition,nextposition)<0.1)
           changeMovementPlank();
    }
    void changeMovementPlank() 
    {
        nextposition = nextposition != positionOne ? positionOne : positiontwo;
    }                        
}

您应该使用当前位置作为 current 参数:

plankTranform.localPosition = Vector3.MoveTowards(plankTranform.localPosition, nextposition,Time.deltaTime*speed);
                                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^
