Once Data Manager is temporary data management utility kit for Unity.

Unity developer who develop the application which has multiple scenes will facing the challenge when they have to pass data between scene. So what does they do ?

Most of Unity developer prefer to use PlayerPrefs to passing data between scene. However, there are a lot of limitation of PlayerPrefs such as the following:

• Only string, float and int can store in PlayerPrefs
• When data are saved in PlayerPrefs, the system writes preference file and save it to your storage ! (But you just only want to pass the data between scene???)

Yeah! we want to break those limitations. So we create this utility for you. Once Data Manager will allow you to pass the data between scene with the power of DontDestroyOnload. We create the temporary storage which you can save kind of Object on it without saving any file on your local storage!

1. Download our Unity Package
2. Import our package by Assets -> Import Package -> Custom Package...
3. Select odm.unitypackage
4. ODM directory will appear on your project.

1. Drag ODM Manager in ODM/Prefabs/ODM Manager.prefab to your scene.
2. So now you can call Once Data Manager Storage to manage your data
3. To access Once Data Manager call the following code:

   GameObject.Find("ODM Manager").GetComponent<DataManager>().Put("Key", data); // To Add
   (DataTypeOfData) GameObject.Find("ODM Manager").GetComponent<DataManager>().Get("Key"); // To Get your data
   GameObject.Find("ODM Manager").GetComponent<DataManager>().Has("Key"); // To Check if key is existed
   GameObject.Find("ODM Manager").GetComponent<DataManager>().Delete("Key"); // To Delete data from Key

Note: You don't have to drag ODM Manager to all of your scene. Just put it on the gateway scene or first scene.

Put your data to the ODM storage

Get your data from the ODM storage.

Note: Please always do type casting when using this method.

Return true if key is existed in the ODM storage.

Delete data from the ODM storage.

The original purpose of this package is to saving data without writing file on user's local storage, so with ODM you can store permanent data on your local storage which can be restored when you open the application on next time like PlayerPrefs.
