关于资源版本管理的问题

unity3d 提供了比读取txt,xml更好用的ScriptableObject（脚本对象化）。为了方便于版本管理，一般会添加一个版本号（guid）

public class ScriptObjectCOS : ScriptableObject
{
public string guid = "";
}

public class LevelPortalRefTable : ScriptObjectCOS
{
public List<LevelPortalRef> levelPortalRefList = new List<LevelPortalRef>();
}

//每个关卡的portral
[System.Serializable]
public class LevelPortalRef
{
public int levelID;
public string levelName = string.Empty;
public List<PortalInstance> PortalInstanceList = new List<PortalInstance>();

//< 1.portalID, 2.PortalInstance>
private Dictionary<int, PortalInstance> cacheLevelPortalRefTable = new Dictionary<int, PortalInstance>();

//缓存所有PortalInstance
public static void PopulatePortalInstanceTable(LevelPortalRef _ref)
{
if (_ref == null) {
return;
}
foreach (PortalInstance _portal in _ref.PortalInstanceList) {
if (!_ref.cacheLevelPortalRefTable.ContainsKey(_portal.portalID)) {
_ref.cacheLevelPortalRefTable.Add(_portal.portalID, _portal);
} else {
Debug.LogError("PortalInstance repeat: " + _ref.levelID + " " + _portal.portalID);
}
}
}

//根据portalID获取PortalInstance
public PortalInstance GetPortalInstanceData(int _portalID)
{
if (cacheLevelPortalRefTable.ContainsKey(_portalID)) {
return cacheLevelPortalRefTable[_portalID];
}
return null;
}
}

[System.Serializable]
public class PortalInstance
{
public int portalID;
public int x;
public float y;
public int z;
public int soloDestinationPortalID;//目标关卡的portal
public string soloDestinationLevelName = string.Empty;//目标关卡名字
public int soloDestinationLevelID;//目标关卡ID
}

然后把创建出来的，已经带有数据的*.assets文件直接打包成*.unity3d文件。

客户端可以直接读取*.unity3d文件，获取到数据
