Pre-arrangements

The following tasks must be completed in advance to implement game information management functions.

1. Logic of completed login method
2. Create a game information table in BACKND Console
3. Create a script exclusive to game information

1. Logic of completed login method

All BACKND functions except login and sign-up require a login process to successfully call their methods.
If the login logic has not been implemented, please implement it according to the guidelines in 1. Implementing Login/Sign-up.

2. Create a game information table in BACKND Console

Go to BACKND Console and click the 'Create Table' button in BACKND Base > Game Information Management > Table.

Create a table with the classification set to private and schema definition to disable.
In this example, the table name is set to USER_DATA.

If the table name is set to something other than USER_DATA, change the value called "USER_DATA" in each example to the name you set.

Click the created table and go to Game Information Management > Data.

The data in this table will be created after the test.

3. Create a script exclusive to game information

Create a new script and change the name to BackendGameData.
Then, open the BackendGameData.cs script and change the content according to the following:

using System.Collections.Generic;
using System.Text;
using UnityEngine;

// Adds BACKND SDK namespace
using BackEnd;

public class UserData {
    public int level = 1;
    public float atk = 3.5f;
    public string info = string.Empty;
    public Dictionary<string, int> inventory = new Dictionary<string, int>();
    public List<string> equipment = new List<string>();

    // This is a method for data debugging.(Debug.Log(UserData);)
    public override string ToString() {
        StringBuilder result = new StringBuilder();
        result.AppendLine($"level : {level}");
        result.AppendLine($"atk : {atk}");
        result.AppendLine($"info : {info}");
        
        result.AppendLine($"inventory");
        foreach(var itemKey in inventory.Keys) {
            result.AppendLine($"| {itemKey} : {inventory[itemKey]}ea");
        }

        result.AppendLine($"equipment");
        foreach(var  equip in equipment) {
            result.AppendLine($"| {equip}");
        }

        return result.ToString();
    }
}

public class BackendGameData {
    private static BackendGameData _instance = null;

    public static BackendGameData Instance {
        get {
            if(_instance == null) {
                _instance = new BackendGameData();
            }

            return _instance;
        }
    }

    public static UserData userData;

    private string gameDataRowInDate = string.Empty;
    
    public void GameDataInsert() {
        // Step 2. Implementing Game Information Insertion 
    }
    
    public void GameDataGet() {
        // Step 3. Implementing Game Information Loading
    }
    
    public void LevelUp() {
        // Step 4. Implementing Game Information Editing
    }
    
    public void GameDataUpdate() {
        // Step 4. Implementing Game Information Editing
    }
}

BackendManager.cs

using UnityEngine;
using System.Threading.Tasks;

// Adds BACKND SDK namespace
using BackEnd;

public class BackendManager : MonoBehaviour {
    void Start() {
        var bro = Backend.Initialize(true); // Initialize BACKND

        // Response value for BACKND initialization
        if(bro.IsSuccess()) {
            Debug.Log("Initialization successful : " + bro); // If successful, 'statusCode 204 Success'
        } else {
            Debug.LogError("Initialization failed : " + bro); // If failed, a 4xx statusCode error occurs 
        }

        Test();
    }

    // A method that allows synchronous methods to be called from asynchronous methods(cannot be accessed by the Unity UI)
    async void Test() {
        await Task.Run(() => {
            BackendLogin.Instance.CustomLogin("user1", "1234"); // BACKND login

            // Adds a logic to implement the game information function
            
            Debug.Log("Test complete.");
        });
    }
}
