JsonUtility worked earlier but after a compile in VS, it stopped i think-CodePudding

Untiies JsonUtility class creates an object, but does not set it's variables.

I'm sure the code is correct, since it worked earlier today. Also tjeked with guides.


public class Player
{
    public int speed;
    public int health;
    public int x;
    public int y;
}

public class Testing : MonoBehaviour
{
    [SerializeField] private TextAsset _textAsset;

    void Start()
    {
        Player p = JsonUtility.FromJson<Player>(_textAsset.text);
        Debug.Log(p.speed); // should print 5
    }
}

{
    "player": {
        "speed": 5,
        "health": 3,
        "x": 0,
        "y": -4
    }
}

The above worked earlier today, and I'm unsure what made it stop. And did input the correct text asset file.

What I think broke it. Went into Visual Studio and compilede once.

I triede to make a new project, but with no success.

The assets are in a Unity package. The following link expires in 7 days. https://easyupload.io/dkmrnd

CodePudding user response：

What you have in your JSON is not the structure your code expects.

First of all yes your player class needs to be

[Serializable]
public class Player
{
    // fields here NO properties!
}

However, your JSON is further nested!

It either needs to be only

{
    "speed": 5,
    "health": 3,
    "x": 0,
    "y": -4
}

Or you need an according wrapper class

[Serializable]
public class JsonRoot
{
    public Player player;
}

and then you would need to do

Player p = JsonUtility.FromJson<JsonRoot>(_textAsset.text).player;
