Question

我已完成以下操作以保存文件中瓶子的坐标。

public class bo：MonoBehaviour {

public GameObject[] bottle;
    public void save()
{
    BinaryFormatter bf = new BinaryFormatter ();
    FileStream file = File.Create(Application.persistentDataPath+"/Info.dat");
    Playerdata data = new Playerdata ();
    data.v[0] = bottle [0].transform.position.ToString();


    bf.Serialize (file,data);
    file.Close ();

}
public void load()
{
    if (File.Exists (Application.persistentDataPath + "/Info.dat")) {
        BinaryFormatter bf = new BinaryFormatter ();
        FileStream file = File.Open (Application.persistentDataPath + "/Initial.dat", FileMode.Open);
        Playerdata data = (Playerdata)bf.Deserialize (file);
        file.Close ();
        Debug.Log("Value "+Vector3FromString(data.x[0]));//line giving runtime error

    }
}

public  Vector3 Vector3FromString(String s)
{
    string[] parts = s.Split(new string[] { "," }, StringSplitOptions.None);
    return new Vector3(
        float.Parse(parts[0]),
        float.Parse(parts[1]),
        float.Parse(parts[2]));
}

[Serializable]
class Playerdata
{
public string v[] = new string[5];
}

这行在调用方法加载时给出了运行时错误。

Debug.Log("Value "+Vector3FromString(data.x[0]));

显示的错误是： - FormatException：Unknown char：

Answer 1

我的矢量序列化功能：

    public static string Vector3ToString(Vector3 v){ // change 0.00 to 0.0000 or any other precision you desire, i am saving space by using only 2 digits
        return string.Format("{0:0.00},{1:0.00},{2:0.00}", v.x, v.y, v.z);
    }

    public static Vector3 Vector3FromString(String s){
        string[] parts = s.Split(new string[] { "," }, StringSplitOptions.None);
        return new Vector3(
            float.Parse(parts[0]),
            float.Parse(parts[1]),
            float.Parse(parts[2]));
    }

Answer 2

Vector3 vector = new Vector3( 1,2,3 );
string s = vector.ToString();
string[] subs = s.Split( "(" )[1].Split( ")" )[0].Split ( "," );
Vector3 vector2 = new Vector3( 
    System.Convert.ToSingle( subs[0] ), 
    System.Convert.ToSingle( subs[1] ), 
    System.Convert.ToSingle( subs[2] ) 
);

Vector3坐标和String之间的转换
