In this guide, we'll walk through the creation of a straightforward game in Unity, perfect for beginners. I've chosen the Solana ecosystem for this project. We will develop a basic collectible game where players can acquire digital assets (NFTs) in a simple 2D environment. This tutorial aims to provide some knowledge on how to enter the trending blockchain games industry simply and effectively, all in less than 10 minutes.

Step 1: Setting Up Your Unity Project
Open Unity Hub and create a new 2D project.Name your project "SimpleSolanaGame".
Step 2: Basic Scene Setup
Once your project is open, go to the "Scene" view.Right-click in the Hierarchy, select 2D Object -> Sprite, to create a ground for your player.Scale the sprite to form a ground platform.Add a Player: Right-click in the Hierarchy, choose Create -> 2D Object -> Sprite. This will be your player. For simplicity, this can just be a colored square.
Step 3: Player Movement
Select the Player sprite in the hierarchy.Add a Rigidbody 2D and a Box Collider 2D from the Inspector.Create a new C# script named "PlayerMovement" and attach it to your Player sprite.Paste this : using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
public float moveSpeed = 5f;
public float jumpForce = 5f;
private Rigidbody2D rb;
private bool isGrounded = true;

void Start()
{
rb = GetComponent<Rigidbody2D>();
}

void Update()
{
float move = Input.GetAxis("Horizontal");
rb.velocity = new Vector2(move * moveSpeed, rb.velocity.y);

if (Input.GetButtonDown("Jump") && isGrounded)
{
rb.AddForce(new Vector2(0f, jumpForce), ForceMode2D.Impulse);
isGrounded = false;
}
}

void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.tag == "Ground")
{
isGrounded = true;
}
}
}
Edit the script to add basic left and right movement and jumping (I can provide a simple script if needed).
Step 4: Incorporating Solana
Navigate to the Solana Unity SDK documentation (link provided in the original instructions).Follow the steps to add the Solana Unity SDK to your project via the Package Manager.Once the SDK is added, download the "SoulPlay" Unity package and import it into your project.
Step 5: Integrating NFTs as Collectibles
In your game, decide what the collectibles will be (these will represent NFTs).Place several collectible sprites around your scene.Write a simple script that detects when the player collides with a collectible and logs a message. This will be the placeholder for NFT collection logic.
Step 6: Setting Up NFT Interaction
Utilize the Solana Unity SDK to connect these collectibles with actual NFTs. For instance, each collectible sprite could represent a unique NFT on the Solana blockchain.Follow the SDK guidelines to assign an NFT to each collectible in the game.
Step 7: Token Swap and Mobile/WebGL Deployment
Introduce a basic UI button for token swapping; use the Solana SDK to integrate actual functionality.Prepare your Unity project for Mobile and WebGL platforms, adjusting settings for performance and compatibility.
Step 8: Testing and Finalizing Your Game
Test the game in Unity to ensure all mechanics work as intended.Build and deploy your game to the desired platforms.Perform final checks to ensure Solana functionality works on all platforms, particularly the NFT collection and token swap features.
Conclusion:
Congratulations! You've just created a simple Solana-integrated game in Unity. This basic setup introduces you to the possibilities of blockchain gaming, allowing players to interact with NFTs within a simple collectible game framework.

You can use ChatGPT if need a bit help, but this article is quite comprehensive. I'm very happy to share that, in a article months ago about how to create a token in seconds, I've helped around 30 people create their first token (hey contacted me). I know it's a small number, but if I could help even one person realize their dreams, I'm already happy.
In the next articles, I'll talk about:
Why and how to learn Unity (It's easy and helps with developing games for blockchains).Best Tokenomics (It's very important to have good tokenomics to prevent your project from becoming a pump and dump).How to attract investments (There's a big list of pages with investors to bring good exposure to your project; I'll provide a Huge list 🔥).How to build a community (Nowadays, many projects share exposure and active followers; in return, their community receives some airdrops. I'll bring a list).

Extra:Create a JavaScript Plugin in Unity:Create a new file called Plugin.jslib in the Assets/Plugins folder in your Unity project.Add the following JavaScript code for a simple Solana connection and NFT fetching:
javascriptCopy code
mergeInto(LibraryManager.library, {
WalletConnect: function () {
// Initialize your Solana connection here
// This is a placeholder function, actual implementation will vary based on your setup
console.log('Wallet connected');
},

FetchNFTs: function () {
// Fetch NFTs logic here
// This is a placeholder function, actual implementation will vary based on your setup
console.log('NFTs fetched');
}
});

Please note, actual JavaScript for connecting to Solana and fetching NFTs would need to be developed based on your specific requirements and the Solana Web3.js library.
In Unity, create a new C# script to call these JavaScript functions, for example, SolanaIntegration.cs.
csharpCopy code
using System.Runtime.InteropServices;
using UnityEngine;

public class SolanaIntegration : MonoBehaviour
{
[DllImport("__Internal")]
private static extern void WalletConnect();

[DllImport("__Internal")]
private static extern void FetchNFTs();

public void ConnectWallet()
{
WalletConnect();
}

public void GetNFTs()
{
FetchNFTs();
}
}

Attach this script to a GameObject in your scene, and you can call ConnectWallet() and GetNFTs() methods, for example, through UI button clicks.
