将文本更改为变量是什么。团结

Question

我正在尝试使文本更改为玩家所剩手榴弹的数量。我已经尝试设置手榴弹的数量3然后开始显示手榴弹的数量是什么为文本也是那样。但我有以下错误：

Assets\Scripts\Throwgrenade.cs(20,24):错误CS0029:无法将类型“int”隐式转换为“UnityEngine.GameObject”

而且

Assets\Scripts\Throwgrenade.cs(23,10):错误CS1624:“Throwgrenade.Update（）”的主体不能是迭代器块，因为“void”不是迭代器接口类型

这是我的代码：

    public int amountOfGrenades = 3;
    public GameObject grenadesText;
    public GameObject NOgrenadesText;


    void Start()
    {
        
        grenadesText = amountOfGrenades;
    }

    void Update()
    {
        if (Input.GetKeyDown("q") && amountOfGrenades >= 1)
        {
            ThrowingGrenade();
        }

        if(amountOfGrenades == 0)
        {

            yield return new WaitForSeconds(5.0f);
            NOgrenadesText.SetActive(true); // Enable the text so it shows
            yield return new WaitForSeconds(5.0f);
            NOgrenadesText.SetActive(false); // Disable the text so it is hidden
        }
    }

第一个错误很容易解释。

你可能是说

grenadesText.GetComponent<Text>().text = amountOfGrenades.ToString();

..或者直接制造

public Text grenadesText;

或您正在使用的任何文本组件（例如tmp_text)

然后不能在update方法中使用yield...只能在IEnumerator方法中使用...

看起来应该有点像

public int amountOfGrenades = 3;
// Simply use the correct type right away
public Text grenadesText;
public GameObject NOgrenadesText;

private void Start()
{     
    grenadesText.text =  amountOfGrenades.ToString();
}

private void Update()
{
    // Avoid the stringed versions wherever possible
    if (Input.GetKeyDown(KeyCode.Q))
    {
        if(amountOfGrenades > 0)
        {
            // I don't know what happens in here
            // but whenever you are increasing or decreasing the amountOfGranades value
            // you again want to call
            // grenadesText.text =  amountOfGrenades.ToString();
            // in order to update the display
            ThrowingGrenade();
        }

        if(amountOfGrenades == 0)
        {
            StopAllCoroutines ();
            StartCoroutine (NoGrenadesRoutine());
        }
    }
}

private IEnumerator NoGrenadesRoutine ()
{
    yield return new WaitForSeconds(5.0f);
    NOgrenadesText.SetActive(true); // Enable the text so it shows
    yield return new WaitForSeconds(5.0f);
    NOgrenadesText.SetActive(false); // Disable the text so it is hidden
}
