Unity：我无法从 unity 项目的 json 文件中获取数据，特别是对象嵌套在对象中

问题描述 投票：0回答：2

所以我需要将一个 json 文件放到字典中，这样我就可以访问里面的位置值，但是我似乎无法全神贯注地围绕格式化类来获取数据。这是json

        ]
      }
    }
  }
}

这就是我所拥有的

public class sceneCreator : MonoBehaviour{
    public TextAsset textJson;
    public RootData A1Data = new RootData();

    void Start(){
        A1Data = JsonUtility.FromJson<RootData>(textJson.);
    }
}

[System.Serializable]
public class PositionData
{
    public float[] location;
    public float[] rotate;
    public float[] scale;
}

[System.Serializable]
public class ModelData
{
    public PositionData[] positions;
}

[System.Serializable]
public class A1DynamicData
{
    public Dictionary<string, ModelData> models;
}

[System.Serializable]
public class RootData
{
    public A1DynamicData A_1_Dynamic;
}

我试图改变根。因为我添加了一个额外的、不需要的部分。但是没有数据被读取。

对于初学者

A-1_Dynamic
！=
A_1_Dynamic
。 JSON 名称必须完全匹配 => 您不能为此使用 
JsonUtility
，因为您不能在 
-
 的字段名称中使用
c#

您需要更改 JSON 中的命名或使用外部工具，如 

Newtonsoft Json.NET
，它允许使用 
[JsonProperty]
 属性覆盖 JSON 名称。

此外，您不能使用

JsonUtility
，因为它使用不支持的Unity Serializer
Dictionary

=> 再次使用 

Newtonsoft Json.NET
，它通过包管理器作为 包出现

A1Data = JsonConvert.DeserializeObject<RootData>(textJson.text);

...


public class RootData
{
    [JsonProperty ("A-1_Dynamic")]
    public A1DynamicData A_1_Dynamic;
}

我使用 https://json2csharp.com/ 获取类和 Newtonsoft Json 包以将所有内容放入我可以访问的类中。
