机会中的公共图像值来自另一个脚本的统一

Question

我的游戏中有雷达。默认情况下，此处显示的图像（MakeRadarObject）。

我正在尝试从另一个脚本（ScanRadar.cs）访问和更改图像，这样当标签匹配时我按下一个按钮，雷达上显示的图像会发生变化，但是我很难实现它并且是希望有人能指出我正确的方向。谢谢！

这是我的scanRadar脚本

public class RadarScan : MonoBehaviour
{
    GameObject Enemy;
    Image RadarImageToChange;

    void Start()
    {
        Enemy = GameObject.Find("Enemy");
    }

    public void ChangeImage(Image UpdateImage)
    {
        if (Enemy.tag == "Enemy")
        {
        RadarImageToChange = Enemy.GetComponent<MakeRadarObject>().image;
            UpdateImage = RadarImageToChange;
        }

    }
}

这是我的MakeRadObject脚本

 public Image image;

// Use this for initialization
void Start () {
    Radar.RegisterRadarObject(this.gameObject, image);
}

void OnDestroy()
{
    Radar.RemoveRadarObject(this.gameObject); 
}


}

这是我的雷达脚本

public class RadarObject
{
public Image icon { get; set; }
public GameObject owner { get; set; }
}

public class Radar : MonoBehaviour {

public Transform playerPos; //position of player
float mapScale = 0.1f; //scale radar size

public static List<RadarObject> radObjects = new List<RadarObject>();

//Registers Object to the radar
public static void RegisterRadarObject(GameObject o, Image i)
{
    Image image = Instantiate(i);
    radObjects.Add(new RadarObject() { owner = o, icon = image }); //adds to List
}

//It loops through the list looking for the owner existing in the list, when it finds the owner is detroys the icon
public static void RemoveRadarObject(GameObject o)
{
    //New list for destroyed objects
    List<RadarObject> newList = new List<RadarObject>();
    for (int i = 0; i < radObjects.Count; i++)
    {
        if (radObjects[i].owner == o)
        {
            Destroy(radObjects[i].icon);
            continue;
        }
         else
            newList.Add(radObjects[i]);
        }
    radObjects.RemoveRange(0, radObjects.Count);
    radObjects.AddRange(newList);
}


void DrawRadarDots()
{
    //loops through the list and for each Object it gets the owners transform position and determins the difference between it's
    //position and the players position, does calculations on the angle and distance and position on a circle using polar equations.
    foreach (RadarObject ro in radObjects)
    {
        Vector3 radarPos = (ro.owner.transform.position - playerPos.position);
        float distToObject = Vector3.Distance(playerPos.position, ro.owner.transform.position) * mapScale;
        float deltay = Mathf.Atan2(radarPos.x, radarPos.z) * Mathf.Rad2Deg - 270 - playerPos.eulerAngles.y;
        radarPos.x = distToObject * Mathf.Cos(deltay * Mathf.Deg2Rad) * -1;
        radarPos.z = distToObject * Mathf.Sin(deltay * Mathf.Deg2Rad);

        //grabs icon of players objects and make it a child of panel and set it's postion based on radarPos.x and radarPos.z
        ro.icon.transform.SetParent(this.transform);
        ro.icon.transform.position = new Vector3(radarPos.x, radarPos.z, 0) + this.transform.position;
    }
}

    //Update is called once per frame
    void Update ()
    {
        DrawRadarDots();
    }
 }
