Unity中LineRenderer视觉显示与自身Positions不匹配问题求助（附路径跟随实现代码）

大家好！我正在Unity里做一个物体沿预设路径移动的功能，目前遇到一个奇怪的问题：LineRenderer的视觉显示和它自身存储的Positions数据不匹配，具体可以看这张[Unity问题截图]。

我的实现流程是这样的：

• 先在Circle.cs脚本里计算出路径的所有点（这里我做的是四分之一圆路径）
• 把计算好的点存储到物体上的LineRenderer组件中
• 最后用Path.cs脚本让目标物体沿着LineRenderer里的这些路径点移动

下面是我用到的两段代码：

Circle.cs（路径点计算脚本） #

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Circle : MonoBehaviour
{
    public float radius = 3;
    private int numPoints = 100;
    private Vector3[] positions;

    void Start()
    {
        positions = new Vector3[numPoints];
        float angleIncrement = (Mathf.PI / 2) / numPoints; // Quarter circle in radians
        for (int i = 0; i < numPoints; i++)
        {
            float angle = angleIncrement * i;
            float x = radius * Mathf.Cos(angle);
            float y = radius * Mathf.Sin(angle);
            positions[i] = new Vector3(x, 0, y);
        }
        this.GetComponent<LineRenderer>().positionCount = numPoints;
        this.GetComponent<LineRenderer>().SetPositions(positions);
    }
}

Path.cs（物体路径跟随脚本） #

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Path : MonoBehaviour
{
    // The linerender path to follow
    public LineRenderer path;
    // The speed at which to follow the path
    public float speed = 5.0f;
    // The current position on the path
    private int currentPosition = 0;

    void Update()
    {
        // Get the current position and target position on the path
        Vector3 currentWaypoint = path.GetPosition(currentPosition);
        Vector3 targetWaypoint = path.GetPosition(currentPosition + 1);

        // Move towards the target waypoint
        transform.position = Vector3.MoveTowards(transform.position, targetWaypoint, speed * Time.deltaTime);

        // If we have reached the target waypoint, move to the next one
        if (transform.position == targetWaypoint)
        {
            currentPosition++;
            // If we have reached the end of the path, start again from the beginning
            if (currentPosition >= path.positionCount)
            {
                currentPosition = 0;
            }
        }
    }
}

我已经尝试过调整LineRenderer的缩放参数，但还是没能解决视觉显示和Positions不匹配的问题，有没有朋友能帮我找找原因或者给出解决方案呀？
