Implementing Nickname Change

1. Write the nickname change method​

Add content to the UpdateNickname method in BackendLogin.cs written in Pre-arrangements.

BackendLogin.cs​

Before editing

    public void UpdateNickname(string nickname) {
        // Logic for Step 4. Implementing Nickname Change
    }

After editing

    public void UpdateNickname(string nickname) {
        Debug.Log("Requesting nickname change.");

        var bro = Backend.BMember.UpdateNickname(nickname);

        if(bro.IsSuccess()) {
            Debug.Log("Nickname change successful : " + bro);
        } else {
            Debug.LogError("Nickname change failed : " + 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.

BackendManager.cs Before editing

    async void Test() {
        await Task.Run(() => {
            BackendLogin.Instance.CustomLogin("user1","1234"); // [Addition] BACKND login
            Debug.Log("Test complete.");
        });
    }

After editing

    async void Test() {
        await Task.Run(() => {
            BackendLogin.Instance.CustomLogin("user1","1234"); // [Addition] BACKND login
            
            BackendLogin.Instance.UpdateNickname("Desired nickname"); // [Addition] Change nickname
            Debug.Log("Test complete.");
        });
    }

3. Test in Unity​

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

The method has been successfully called when the log displays 'Nickname change successful. : 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 UpdateNickname error case.

When statusCode : 409 error occurs​

When changing the nickname 2 or more times without changing the logic, this error occurs due to the command attempting to change the nickname to a preexisting one.
The parameter value that goes inside UpdateNickname of BackendManager.cs should be changed to a value different from the nickname that was originally entered.

4. Check in the console​

Go to BACKND Console, and in BACKND Base > User Management check that the changed nickname is displayed properly for the logged-in user.
