Implementing Game Information Editing

1. Write a game information edit method

Add content to the LevelUp and GameDataUpdate methods in BackendGameData.cs written in Pre-arrangements.

BackendGameData.cs

Before editing

    public void LevelUp() {
        // Step 4. Implementing Game Information Editing
    }

    public void GameDataUpdate() {
        // Step 4. Implementing Game Information Editing
    }

After editing

    public void LevelUp() {
        Debug.Log("Increases the level by 1.");
        userData.level += 1;
        userData.atk += 3.5f;
        userData.info = "Changes details.";
    }

    // Edit game information
    public void GameDataUpdate() {
        if(userData == null) {
            Debug.LogError("Data downloaded from the server or newly inserted data does not exist. Use Insert or Get to create data.");
            return;
        }

        Param param = new Param();
        param.Add("level", userData.level);
        param.Add("atk", userData.atk);
        param.Add("info", userData.info);
        param.Add("equipment", userData.equipment);
        param.Add("inventory", userData.inventory);

        BackendReturnObject bro = null;
        
        if(string.IsNullOrEmpty(gameDataRowInDate)) {
            Debug.Log("Requests my latest game information data to be edited.");

            bro = Backend.GameData.Update("USER_DATA", new Where(), param);
        } else {
            Debug.Log($"Requests {gameDataRowInDate} to be edited.");

            bro = Backend.GameData.UpdateV2("USER_DATA", gameDataRowInDate, Backend.UserInDate, param);
        }

        if(bro.IsSuccess()) {
            Debug.Log("Successfully edited game information data. : " + bro);
        } else {
            Debug.LogError("Failed to edit game information data. : " + bro);
        }
    }

2. Add method call to BackendManager.cs

BackendManager, which is automatically called when the game is executed, must be used to call this method.
Add it so that the method may be called after BACKND initialization and BACKND login.

BackendManager.cs

Before editing(After Step 3. Game Information Loading)

    async void Test() {
        await Task.Run(() => {
            BackendLogin.Instance.CustomLogin("user1", "1234"); // BACKND login

            BackendGameData.Instance.GameDataGet(); //[Addition] Data loading method

            Debug.Log("Test complete.");
        });
    }

After editing

    async void Test() {
        await Task.Run(() => {
            BackendLogin.Instance.CustomLogin("user1", "1234"); // BACKND login

            BackendGameData.Instance.GameDataGet(); // Data insertion method
            
            // [Addition] When the loaded data from the server does not exist, new data is created and inserted
            if(BackendGameData.userData == null) {
                BackendGameData.Instance.GameDataInsert();
            }

            BackendGameData.Instance.LevelUp(); // [Addition] Locally saved data is changed

            BackendGameData.Instance.GameDataUpdate(); //[Addition] Overwrites data saved in the server(only parts that have changed)

            Debug.Log("Test complete.");
        });
    }

3. Test in Unity

After editing the script, execute Unity debugging and check the console log of Unity.

The process has been successfully completed when the log displays 'Requesting my latest game information data to be edited : statusCode : 204'.
When errors, such as statusCode : 400, 404, and 409, occur instead of the above log, you can check which error caused the failure in Update error case.

4. Check in the console

When a log on success appears on the Unity console, go to BACKND Console and check BACKND Base > Game Information Management > Data to confirm that the row has been changed.
The value increases every time the method is called; therefore, it may differ from the value in the example below.
