BACKND Guidelines > 4. Implementing Chart Functions > Step 1. Pre-arrangements

Pre-arrangements

The following tasks must be completed in advance to implement chart functions.

1. Logic of completed login method
2. Create a script exclusive to charts

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 script exclusive to charts

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

BackendChart.cs

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

// Adds BACKND SDK namespace
using BackEnd;

public class BackendChart {
    private static BackendChart _instance = null;

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

            return _instance;
        }
    }

    public void ChartGet(string chartId) {
        // Adds content of Step 3. Loading Chart Information
    }
}

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 method

            // Adds logic for loading chart information
            
            Debug.Log("Test complete.");
        });
    }
}
