Question

尝试隐藏并显示一组带有标签的克隆对象时出现错误。克隆是动态的（位置）。我已切换到可见和可见的一些信息文本。现在，我想使用标签隐藏和取消隐藏游戏对象。（“ windtag”）。还要尝试用箭头方法将那些游戏对象隐藏起来。

public GameObject[] test;


public void invisible(bool log)
    {


        test= GameObject.FindGameObjectsWithTag("windtag");
        test.GetComponent<Renderer>().enabled = log;

    }
 
public void clone()
    {
        Canvas newcanvas = Instantiate(canvas);
        //Use .SetParent(canvasName,false)    
        Text cloneposition = Instantiate(shiposition, newpos);
        Text clonewind = Instantiate(windspeedtext, newpos);
        Text clonedlow = Instantiate(flowtext, newpos);
        Text clonetemperature = Instantiate(temperaturetext, newpos);
        newcanvas.transform.position = shipvalue.transform.position;
        cloneposition.transform.SetParent(newcanvas.transform, false);
        clonewind.transform.SetParent(newcanvas.transform, false);
        clonedlow.transform.SetParent(newcanvas.transform, false);
        clonetemperature.transform.SetParent(newcanvas.transform, false);
        clonewind.gameObject.SetActive(false);
        clonetemperature.gameObject.SetActive(false);
        
    }

 public void arrow(float[,] arrowdata)
    {
        for (int x = 0; x < arrowdata.GetLength(0); x++)
        {
            for (int y = 0; y < arrowdata.GetLength(1); y++)
            {
                if (grid[x,y] ==1)
                {


                    if (arrowdata[x, y] == 5)
                    {
                        GameObject referenceArrow = Instantiate(Resources.Load("down")) as GameObject;
                        float posY = shipvalue.transform.position.y - 9f;
                        referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x-0.5f, posY);
                    }
                    if (arrowdata[x, y] == 4)
                    {
                        GameObject referenceArrow = Instantiate(Resources.Load("top left")) as GameObject;
                        float posY = shipvalue.transform.position.y - 9f;
                        referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x - 0.5f, posY);
                    }
                    if (arrowdata[x, y] == 3)
                    {
                        GameObject referenceArrow = Instantiate(Resources.Load("top right")) as GameObject;
                        float posY = shipvalue.transform.position.y - 9f;
                        referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x - 0.5f, posY);
                    }
                }
            }
        }

    }

我认为您当前的问题是，有多个对象带有标签“ windtag”。因此，如果您使用该标签搜索GameObject，则会返回多个。产生一个GameObject数组而不是一个GameObject。

一个简单的解决方法是向所有GameObject添加不同的Tag，然后将该字符串赋予函数。

invisible(false, "tagexample1");

public void invisible(bool log, string tag)
{
    test= GameObject.FindGameObjectWithTag(tag);

    test.GetComponent<Renderer>().enabled = log;
}

或者您可以将GetComponent<Renderer>()放入for循环中。隐藏/显示带有标签的所有元素。如果那是您想要的。

public void invisible(bool log)
{
    test= GameObject.FindGameObjectsWithTag("windtag");

    foreach (GameObject gm in test){
        gm.GetComponent<Renderer>().enabled = log;
    }
}

使用标签隐藏克隆游戏对象
