With this key area of my portfolio, I bring Best Practices and Optimization techniques.

Below I discuss a client-server API for gaming. If you want to see other backend topics, see these;

RMC

Together with my teams, I have released free and premium code packages released under Rivello Multimedia Consulting (RMC) including Unity and Godot tooling and APIs. Checkout the highlights.

RMC Buff

Subsystems

• Buff.Instance.Accounts – Responsible for user authentication
• Buff.Instance.Database – Manages server data
• Buff.Instance.CloudCode – Calls server functionality

Buff API

This RMC Backend library has a main BackendSystem (e.g. Buff.Instance) with subsystems of Accounts, Database, and CloudCode. The architecture is flexible too. Developers can scale it by adding and updating new subsystems for specific needs.

This is a custom API created by RMC.

1. Accounts 👨‍💼

Accounts is responsible for user authentication.

//


// Observe
Buff.Instance.OnInitialized.AddListener((buff) => { Debug.LogWarning("@@ Buff.OnInitialized()"); });
Buff.Instance.Accounts.OnUserCreate.AddListener((accounts) => { Debug.LogWarning("@@ Buff.OnUserCreate()"); });
Buff.Instance.Accounts.OnUserDelete.AddListener((accounts) => { Debug.LogWarning("@@ Buff.OnUserDelete()"); });
Buff.Instance.Accounts.OnUserSignIn.AddListener((accounts) => { Debug.LogWarning("@@ Buff.OnUserSignIn()"); });
Buff.Instance.Accounts.OnUserSignOut.AddListener((accounts) => { Debug.LogWarning("@@ Buff.OnUserSignOut()"); });


// Initialize
await Buff.Instance.InitializeAsync();


// Prepare
string userEmail = "test@email.com";
string userPassword = "abc123";
string userNickname = "testName";


// Check
if (!Buff.Instance.Accounts.HasUser())
{

    // Create User
    var createUserResponse = await Buff.Instance.Accounts.UserCreateAsync(userEmail, userPassword, userNickname);

    if (!createUserResponse.IsSuccess)
    {
        Debug.Log($"{createUserResponse.ErrorMessage}");
        return;
    }



    // SignIn User
    var signInUserResponse = await Buff.Instance.Accounts.UserSignInAsync(userEmail, userPassword);
    if (!signInUserResponse.IsSuccess)
    {
        Debug.Log($"{createUserResponse.ErrorMessage}");
        return;
    }

    // Response
    Debug.Log($"Result = {signInUserResponse.User.Email}");
}


//

2. Database 💾

Database is responsible for managing server data.

//


// Observe
Buff.Instance.OnInitialized.AddListener((buff) => { Debug.LogWarning("@@ Buff.OnInitialized()"); });
Buff.Instance.Database.OnTableRead.AddListener((database) => { Debug.LogWarning("@@ Buff.OnTableRead()"); });
Buff.Instance.Database.OnItemCreate.AddListener((database) => { Debug.LogWarning("@@ Buff.OnItemCreate()"); });
Buff.Instance.Database.OnItemRead.AddListener((database) => { Debug.LogWarning("@@ Buff.OnItemRead()"); });
Buff.Instance.Database.OnItemUpdate.AddListener((database) => { Debug.LogWarning("@@ Buff.OnItemUpdate()"); });


// Initialize
await Buff.Instance.InitializeAsync();


// Prepare
var user = Buff.Instance.Accounts.GetUser();
var table = new Table("InventoryTable");
var item = new Item("Gold");


// Check
if (user != null)
{
    // Add Item To Table
    var itemCreateResponse = await Buff.Instance.Database.ItemCreateAsync(table, user, item); 
    if (!itemCreateResponse.IsSuccess)
    {
        Debug.Log($"{itemCreateResponse .ErrorMessage}");
        return;
    }

    // Response
    Debug.Log($"Result = {itemCreateResponse.Item.Quantity} of {itemCreateResponse.Item.Name}");
}


//

3. CloudCode ☁️

CloudCode is responsible for calling server-side code.

//


// Observe
Buff.Instance.OnInitialized.AddListener((buff) => { Debug.LogWarning("@@ Buff.OnInitialized()"); });
Buff.Instance.CloudCode.OnMethodCall.AddListener((cloudCode) => { Debug.LogWarning("@@ Buff.OnMethodCall()"); });


// Initialize
await Buff.Instance.InitializeAsync();


// Prepare
string functionName = "HelloWorld";
Dictionary<string, string> args = new Dictionary<string, string>();
args.Add("message", "this is from the client");


// Check
if (user != null)
{
    // Call Server Code
    var methodCallResponse = await Buff.Instance.CloudCode.MethodCallAsync<string>(functionName, args);

    if (!methodCallResponse.IsSuccess)
    {
        Debug.Log($"{methodCallResponse.ErrorMessage}");
        return;
    }

    // Response
    Debug.Log($"Result = {response.Data}");
}

This repo is the ideal starting point for new Unity projects with AWS using RMC Buff.

Repo link not yet available. Its a work-in-progress 🙂
