【问题描述】:
我想反序列化包含关卡信息的 json 文件。鉴于此示例 .json 文件名为 1.json
{
"name": "Level One",
"map": [
[{
"groundTexture": "grass",
"cellType": "empty",
"masterField": null,
"worldObjects": [{
"worldObjectType": "player",
"rotation": 90
}]
},{
"groundTexture": "grass",
"cellType": "obstacle",
"masterField": null,
"worldObjects": [{
"worldObjectType": "tree",
"rotation": 0
}]
}],[{
"groundTexture": "grass",
"cellType": "campFire",
"masterField": null,
"worldObjects": [{
"worldObjectType": "campfire",
"rotation": 270
}]
},{
"groundTexture": "grass",
"cellType": "related",
"masterField": {
"x": 1,
"y": 0
},
"worldObjects": []
}]
]
}
我想将该文件中的数据转换为一个类对象,该类对象包含在运行时创建关卡所需的所有数据。我创建了一个只读取文件内容的阅读器
public class LevelReader : MonoBehaviour
{
private string levelBasePath;
private void Awake()
{
levelBasePath = $"{Application.dataPath}/ExternalFiles/Levels";
}
public string GetFileContent(string levelName)
{
string file = $"{levelName}.json";
string filePath = Path.Combine(levelBasePath, file);
return File.ReadAllText(filePath);
}
}
以及一个将 json 字符串映射到 LevelInfo 对象的映射器。
public class LevelMapper : MonoBehaviour
{
private void Start()
{
// DEBUGGING TEST
LevelReader levelReader = GetComponent<LevelReader>();
string levelContent = levelReader.GetFileContent("1");
LevelInfo levelInfo = MapFileContentToLevelInfo(levelContent);
Debug.Log(levelInfo.cells);
}
public LevelInfo MapFileContentToLevelInfo(string fileContent)
{
return JsonUtility.FromJson<LevelInfo>(fileContent);
}
}
以下结构只是帮助创建一个包含所有关卡数据的对象:
[Serializable]
public struct LevelInfo
{
public string name;
public LevelCell[][] cells;
}
[Serializable]
public struct LevelCell
{
public string groundTexture;
public string cellType;
public Vector2? masterField;
public LevelWorldObject[] worldObjects;
}
[Serializable]
public struct LevelWorldObject
{
public string worldObjectType;
public int rotation;
}
当启动应用程序时,映射器运行并循环遍历数据对象。不幸的是,单元格是空的。如何正确反序列化文件?
