Question

我有一个下拉菜单，这个下拉列表给出了我可以通过滑块移动的游戏对象列表。基本上我要做的就是让x，y，z滑块在每个轴上移动游戏对象。我现在的问题是PlayerPrefs。我想要的一切都像魅力一样，但问题是，当我移动游戏对象并退出应用程序时，它并没有保存。下拉列表用于选择要移动的游戏对象。任何人都可以帮我吗？

这是附加到Slider的脚本。

 public enum Axis{
x,y,z
};

public enum Options{
position,scale,fov,particlesystem, ui
};

public Axis axis;
public Options options;
public TMP_InputField inputField;
public TMP_InputField maxSliderInputField;

public Slider slider;
public GameObject gameObject;
public Text text;

Vector3 pos;
Vector3 tempPos;


public string playerPrefsFloatId;
public string playerPrefsStringId;
public string maxValueId;

public GameObject[] iconstoMove; // my Objects that i can choose from dropdown
public TMP_Dropdown dropDown;

if (PlayerPrefs.HasKey(playerPrefsFloatId))
    {
        slider.value = PlayerPrefs.GetFloat(playerPrefsFloatId);
        text.text = PlayerPrefs.GetString(playerPrefsStringId);
        SliderOptions();

        GetAxis();

        Debug.Log ("Have Key" + playerPrefsFloatId);

    }

        void SaveUISettings()
{
    PlayerPrefs.SetFloat(playerPrefsFloatId, slider.value);
    PlayerPrefs.SetFloat(maxValueId, slider.maxValue);
    PlayerPrefs.SetString(playerPrefsStringId, text.text);

    PlayerPrefs.Save();
}

// i use this to move object depending on axis.
void UiMovement()
{
    switch (axis)
    {
        case Axis.x:
            pos = OnValueDropDownChanged().transform.position;//gameObject.transform.position;
            pos.x = slider.value;
            OnValueDropDownChanged().transform.position = pos;
        Debug.Log ("HI");
        //  gameObject = OnValueDropDownChanged();
        //  gameObject.transform.position = pos;
        PlayerPrefs.Save();
            break;

        case Axis.y:
        pos = OnValueDropDownChanged().transform.position;      
        pos.y = slider.value;
            //gameObject = OnValueDropDownChanged();
        OnValueDropDownChanged().transform.position = pos;
        PlayerPrefs.Save();
            break;

        case Axis.z:
        pos = OnValueDropDownChanged().transform.position;      
            pos.z = slider.value;
            //gameObject = OnValueDropDownChanged();
        OnValueDropDownChanged().transform.position = pos;
        PlayerPrefs.Save();
                break;

        default:
            Debug.LogWarning("Please Choose Axis!");
            break;
    }
}

// This is how i choose my gameobject from the dropdown
private GameObject OnValueDropDownChanged()
{
    if (dropDown.value == 0)
    {
        Debug.Log ("Im Index Number " + "I'm 0");

        // TODO: Movement for 0 Index
    //  Debug.Log (iconstoMove[0].name  + " This is the name " + iconstoMove[0].transform.position + "Transform of the object");
        return iconstoMove[0];
    }


    else if (dropDown.value == 1)
    {
        Debug.Log ("Im Index Number " + "I'm 1");
        return  iconstoMove[1];
    }
    else if (dropDown.value == 2)
    {
        Debug.Log ("Im Index Number " + "I'm 2");
        return  iconstoMove[2];
    }

    else if (dropDown.value == 3)
    {
        Debug.Log ("Im Index Number " + "I'm 3");
        return  iconstoMove[3];
    }

    else if (dropDown.value == 4)
    {
        Debug.Log ("Im Index Number " + "I'm 4");
        return  iconstoMove[4];
    }

    else if (dropDown.value == 5)
    {
        Debug.Log ("Im Index Number " + "I'm 5");
        return  iconstoMove[5];
    }

    else if (dropDown.value == 6)
    {
        Debug.Log ("Im Index Number " + "I'm 6");
        return  iconstoMove[6];
    }

    else if (dropDown.value == 7)
    {
        Debug.Log ("Im Index Number " + "I'm 7");
        return  iconstoMove[7];
    }

    return null;
}

现在我还有许多其他游戏对象的滑块，它们不会使用下拉列表。他们都按我的意愿工作。我唯一的问题是，当我从下拉列表中选择对象时，它永远不会保存，究竟发生了什么？
