c# - 更新功能在 AR 应用程序中不起作用

Question

我正在开发显示附近 POI 的 AR 应用程序。正如您在下面的屏幕截图中看到的那样，ArAlignedMap 有一个脚本，允许我们使用真实世界坐标创建 POI。[WorldScaleAr][1]

我分配的 POI 标记预制件之一是 POI45。POI45 在下面的屏幕截图中有对象。[POI45][2]

我为 LabelIcon 编写了一个脚本。该脚本如下；

脚本运行后，POI 的颜色会发生变化，但不会在每一帧中都发生变化。为什么它不更新 POI 的颜色？

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System;
using static System.Math;
using Mapbox.Examples; // example script import

public class gradient45 : MonoBehaviour
{

    Vector3 temp;
    float temp2;
    float distances;
    int z = 2;
    float gra = 0;
    double r = 6371000;
    double[,] coords = new double[,] { { 39.872446, 32.735564 } }; // Eğitim Fakültesi
    double lat1;
    double lat2;
    double lon1;
    double lon2;
    double user_lat;
    double user_lat_rad;
    double user_lon;
    double user_lon_rad;
    String x;
    String y;
    // Start is called before the first frame update
    void Start()
    {
        // get poi Location
        lat1 = Math.PI * coords[0, 0] / 180.0;
        // lat2 = Math.PI * user[0, 0] / 180.0;
        lon1 = Math.PI * coords[0, 1] / 180.0;
        // lon2 = Math.PI * user[0, 1] / 180.0;

    }

    // Update is called once per frame
    void Update()
    {
        // Get user location
        // Latitude
        x = getLocation.x1.ToString();
        user_lat = Convert.ToDouble(x);
        user_lat_rad = Math.PI * user_lat / 180.0; // Radian
        // Longitude
        y = getLocation.y1.ToString();
        user_lon = Convert.ToDouble(y);
        user_lon_rad = Math.PI * user_lon / 180.0; // Radian

        // Change POIs sizes
        distances = Convert.ToSingle(distance(user_lat_rad, user_lon_rad));
        temp2 = gra;
        temp2 = temp2 + 100f;
        gra = temp2;

        GetComponent<Renderer>().material.color = new Color((gra/255f), 161f/255f, 127f/255f);


    }
    public double distance(double lat2, double lon2)
    {
        // Haversine Formula
        // Lat2,Lon2 = User Location
        // Lat1,Lon1 = POI Location
        double dist1 = Sqrt((Pow(Sin((lat2 - lat1) / 2), 2)) + Cos(lat2) * Cos(lat2) * (Pow(Sin((lon2 - lon1) / 2), 2)));
        double distance = 2 * r * Asin(dist1);
        return distance;
    }
} ```
