    - Name your script (e.g., "MoveCube").
    - Open the Script:
    - Double-click on the script to open it in Visual Studio.

Step 2: Understanding the Script Structure

- When you create a new script, Unity generates a basic template for you. 
    - Here is an example of what the initial script might look like:

```
using UnityEngine;

public class MoveCube : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
    }

    // Update is called once per frame
    void Update()
    {
    }
}
```

- Key Components:
    - *using UnityEngine;*: This line includes the UnityEngine namespace, which contains the core classes and functions for Unity.
    - *public class MoveCube : MonoBehaviour*: This defines a new class named MoveCube that inherits from MonoBehaviour. Inheriting from MonoBehaviour allows the script to be attached to GameObjects and use Unity's built-in methods.
    - *void Start()*: This method is called once when the script is first enabled. It is typically used for initialization.
    - *void Update()*: This method is called once per frame. It is used for regular updates, such as handling input or moving objects.

Step 3: Writing the Script
- Let's modify the script to move the cube forward continuously.
    - Modify the Script:
        - Replace the contents of the script with the following code:

```
using UnityEngine;

public class MoveCube : MonoBehaviour
{
    void Update()
    {
        // Move the cube forward continuously
        transform.Translate(Vector3.forward * Time.deltaTime);
    }
}
```

- Explanation:
    - *transform.Translate(Vector3.forward * Time.deltaTime);*: This line moves the GameObject forward along the Z-axis. Vector3.forward represents the forward direction, and Time.deltaTime ensures the movement is frame rate independent.
- Save the Script:
    - Save the script in Visual Studio (File > Save or Ctrl+S).

Step 4: Attaching the Script to a GameObject
- Select the GameObject:
    - In the Hierarchy window, select the cube you created earlier.
- Attach the Script:
    - Drag the MoveCube script from the Project window onto the cube in the Hierarchy window.
    - Alternatively, you can click the "Add Component" button in the Inspector window, type "MoveCube" in the search box, and select the script from the list.

Step 5: Running the Game

- Play the Game:
    - Click the "Play" button in the toolbar to run your game.
    - You will see the cube move forward continuously.
- Stop the Game:
    - Click the "Play" button again to stop the game.

Step 6: Enhancing the Script

- Let's enhance the script to allow user input to control the cube's movement.
    - Modify the Script:
        - Open the MoveCube script in Visual Studio.
        - Replace the contents of the Update method with the following code:

```
using UnityEngine;

public class MoveCube : MonoBehaviour
{
    public float speed = 5f;

    void Update()
    {
        // Get input from the horizontal and vertical axes
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        // Create a movement vector
        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        // Move the cube based on user input
        transform.Translate(movement * speed * Time.deltaTime);
    }
}
```

- Test the Enhanced Script:
    - Save the script and go back to Unity.
    - Click the "Play" button to run your game.
    - Use the arrow keys or WASD keys to move the cube in different directions.

## Summary
By following these steps, you will have created your first script, attached it to a GameObject, and written custom behavior to control its movement. Understanding the basics of scripting in Unity is essential for creating interactive and dynamic games. These foundational skills will enable you to build more complex behaviors and interactions as you progress in your game development journey.

## Summary
By following these steps, you will have successfully created a simple wallet in Unity using CardanoSharp, enabling you to generate and manage mnemonics, private keys, and public keys.


2.2 Creating a Simple Wallet

## Key Concepts

*Mnemonic*:
A mnemonic is a human-readable representation of a private key, usually in the form of a series of words. It is used to generate private and public keys. The mnemonic phrase is crucial for recovering a wallet and should be stored securely. In CardanoSharp, the MnemonicService is used to generate mnemonics, which can be in different word counts such as 12, 15, 18, 21, or 24 words.

*Private Key*:
A private key is a secret key used to sign transactions and prove ownership of a blockchain address. It is derived from the mnemonic and is essential for accessing and managing funds in a wallet. The private key should never be shared or exposed. In CardanoSharp, the PrivateKeyService is used to generate private keys from a mnemonic.

*Public Key*:
A public key is derived from the private key and is used to receive transactions. It can be shared publicly without compromising the security of the wallet. The public key is used to generate addresses where funds can be sent. In CardanoSharp, the public key is obtained from the private key using the GetPublicKey method.

## Detailed Explanation

*Mnemonic*:
The mnemonic phrase is a sequence of words that encodes a random number used to generate a private key. This method of key generation is standardized by the BIP-39 protocol. The mnemonic phrase makes it easier for users to back up and restore their wallets. For example, a 24-word mnemonic provides a high level of security due to the large number of possible combinations.

*Private Key:*
The private key is a 256-bit number that is generated from the mnemonic phrase. It is used to sign transactions, which proves that the transaction was authorized by the owner of the private key. The security of the private key is paramount; if someone gains access to it, they can control the funds in the wallet. In CardanoSharp, the private key is generated using the GeneratePrivateKey method from the PrivateKeyService.

*Public Key*:
The public key is derived from the private key using elliptic curve cryptography. It is used to create addresses that can receive funds. The public key does not need to be kept secret and can be shared with others. In CardanoSharp, the public key is obtained from the private key using the GetPublicKey method. The public key is then used to generate a Cardano address where funds can be sent.

## Example Code


Here is an example of how these concepts are implemented in the WalletManager script from the previous section:

```
using UnityEngine;
using CardanoSharp.Wallet;
using CardanoSharp.Wallet.Models.Keys;

public class WalletManager : MonoBehaviour
{
    private Mnemonic _mnemonic;
    private PrivateKey _privateKey;
    private PublicKey _publicKey;

    void Start()
    {
        // Generate a new mnemonic
        _mnemonic = new MnemonicService().Generate(WordLists.English, WordCount.TwentyFour);
        Debug.Log("Mnemonic: " + _mnemonic);

        // Generate private and public keys
        _privateKey = new PrivateKeyService().GeneratePrivateKey(_mnemonic);
        _publicKey = _privateKey.GetPublicKey();
        Debug.Log("Private Key: " + _privateKey);
        Debug.Log("Public Key: " + _publicKey);
    }
}
```

In this script:

- A new mnemonic is generated using the MnemonicService.
- The private key is generated from the mnemonic using the PrivateKeyService.
- The public key is derived from the private key using the GetPublicKey method.

## Summary
By understanding these key concepts, you can effectively manage wallets and keys in your Cardano-based Unity projects using CardanoSharp.



2.3 Understanding Wallets and Keys

Step 1: Create a new C# script in Unity and name it "TransactionManager".

- In the Unity Editor, navigate to the Project window. Right-click in the Assets folder, select Create > C# Script, and name the script TransactionManager.

Step 2: Open the script in Visual Studio and replace the contents with the following code:

```
using UnityEngine;
using CardanoSharp.Wallet;
using CardanoSharp.Wallet.Models.Transactions;
using CardanoSharp.Wallet.Models.Keys;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

public class TransactionManager : MonoBehaviour
{
    private WalletManager _walletManager;
    private static readonly HttpClient client = new HttpClient();

    void Start()
    {
        _walletManager = GetComponent<WalletManager>();

        // Create a new transaction
        Transaction transaction = new Transaction
        {
            // Add transaction details here
            Inputs = new List<TransactionInput>
            {
                new TransactionInput
                {
                    TransactionId = "previous_transaction_id",
                    Index = 0
                }
            },
            Outputs = new List<TransactionOutput>
            {
                new TransactionOutput
                {
                    Address = "recipient_address",
                    Value = new Value
                    {
                        Coin = 1000000 // Amount in lovelaces (1 ADA = 1,000,000 lovelaces)
                    }
                }
            },
            Fee = 200000 // Transaction fee in lovelaces
        };

        // Sign the transaction with the private key
        transaction.Sign(_walletManager.PrivateKey);

        // Send the transaction
        SendTransaction(transaction).Wait();
    }

    private async Task SendTransaction(Transaction transaction)
    {
        string transactionHex = transaction.ToHex();
        var content = new StringContent(transactionHex, Encoding.UTF8, "application/json");

        HttpResponseMessage response = await client.PostAsync("https://cardano-node-url/api/submit", content);
        if (response.IsSuccessStatusCode)
        {
            Debug.Log("Transaction sent successfully!");
        }
        else
        {
            Debug.LogError("Failed to send transaction: " + response.ReasonPhrase);
        }
    }
}
```

Step 3: Save the script and go back to Unity.
- Save the changes in Visual Studio and return to the Unity Editor. Unity will automatically compile the script.

Step 4: Attach the "TransactionManager" script to the WalletManager GameObject.
- With the WalletManager GameObject selected, drag the TransactionManager script from the Project window to the Inspector window to attach it.

Step 5: Click the "Play" button to run your game. You should see the transaction details printed in the Console window.
- Click the Play button in the Unity Editor. The Start method in the TransactionManager script will execute, creating and signing a transaction. The details of the transaction will be printed to the Console window.

## Additional Tips
**Transaction Details:**
Ensure that you fill in the transaction details such as the recipient address, amount, and any other necessary information before signing and sending the transaction. The example above includes placeholders for transaction inputs, outputs, and fees.

**Network Integration:**
To send the transaction to the Cardano network, you will need to integrate with a Cardano node or use a service that provides access to the Cardano blockchain. This typically involves using an API to submit the signed transaction.

**Error Handling:**
Implement error handling to manage any issues that may arise during the transaction creation, signing, or sending process. This can include checking for network connectivity, validating transaction details, and handling exceptions.

## Example Code for Sending Transaction

Here is an example of how you might extend the TransactionManager script to send the transaction to the Cardano network:

```
using UnityEngine;
using CardanoSharp.Wallet;
using CardanoSharp.Wallet.Models.Transactions;
using CardanoSharp.Wallet.Models.Keys;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

public class TransactionManager : MonoBehaviour
{
    private WalletManager _walletManager;
    private static readonly HttpClient client = new HttpClient();

    void Start()
    {
        _walletManager = GetComponent<WalletManager>();

        // Create a new transaction
        Transaction transaction = new Transaction
        {
            // Add transaction details here
            Inputs = new List<TransactionInput>
            {
                new TransactionInput
                {
                    TransactionId = "previous_transaction_id",
                    Index = 0
                }
            },
            Outputs = new List<TransactionOutput>
            {
                new TransactionOutput
                {
                    Address = "recipient_address",
                    Value = new Value
                    {
                        Coin = 1000000 // Amount in lovelaces (1 ADA = 1,000,000 lovelaces)
                    }
                }
            },
            Fee = 200000 // Transaction fee in lovelaces
        };

        // Sign the transaction with the private key
        transaction.Sign(_walletManager.PrivateKey);

        // Send the transaction
        SendTransaction(transaction).Wait();
    }

    private async Task SendTransaction(Transaction transaction)
    {
        string transactionHex = transaction.ToHex();
        var content = new StringContent(transactionHex, Encoding.UTF8, "application/json");

        HttpResponseMessage response = await client.PostAsync("https://cardano-node-url/api/submit", content);
        if (response.IsSuccessStatusCode)
        {
            Debug.Log("Transaction sent successfully!");
        }
        else
        {
            Debug.LogError("Failed to send transaction: " + response.ReasonPhrase);
        }
    }
}
```

In this extended script:

The SendTransaction method converts the transaction to a hexadecimal string and sends it to a Cardano node using an HTTP POST request.
The response from the node is checked to determine if the transaction was sent successfully.

## Summary

By following these steps, you will have successfully created and sent a transaction in Unity using CardanoSharp. This example incorporates elements from Aiken to give you a clearer picture of what a transaction looks like, including inputs, outputs, and fees.

3.4 Integrating CardanoSharp with Game Mechanics

## Introduction

In this section, we will create a basic user interface (UI) to display player information such as score, collected items, and ADA balance. This will enhance the player's experience by providing important feedback and information.

## Implementing a User Interface (UI)

Step 1: Create a Canvas
- In the Hierarchy window, right-click and select UI > Canvas. This will create a new Canvas GameObject.
    - Name the Canvas "GameUI".

Step 2: Create a Text Element for the Score
- Right-click on the Canvas GameObject in the Hierarchy window and select UI > Text. This will create a new Text GameObject.
    - Name the Text GameObject "ScoreText".
    - In the Inspector window, customize the Text component to display the initial score (e.g., "Score: 0").
        - Adjust the font size, color, and position of the text as needed.

Step 3: Create a Text Element for the ADA Balance
- Right-click on the Canvas GameObject in the Hierarchy window and select UI > Text. This will create a new Text GameObject.
    - Name the Text GameObject "ADABalanceText".
    - In the Inspector window, customize the Text component to display the initial ADA balance (e.g., "ADA: 0").
        - Adjust the font size, color, and position of the text as needed.

Step 4: Create a New C# Script for UI Management
- In the Project window, right-click in the "Assets" folder, select Create > C# Script, and name it "UIManager".

Step 5: Edit the Script
- Open the script in Visual Studio and replace the contents with the following code:


```
using UnityEngine;
using UnityEngine.UI;

public class UIManager : MonoBehaviour
{
    public Text scoreText;
    public Text adaBalanceText;
    private int score = 0;
    private int adaBalance = 0;

    void Start()
    {
        UpdateScoreText();
        UpdateADABalanceText();
    }

    public void AddScore(int amount)
    {
        score += amount;
        UpdateScoreText();
    }

    public void UpdateADABalance(int amount)
    {
        adaBalance += amount;
        UpdateADABalanceText();
    }

    void UpdateScoreText()
    {
        scoreText.text = "Score: " + score.ToString();
    }

    void UpdateADABalanceText()
    {
        adaBalanceText.text = "ADA: " + adaBalance.ToString();
    }
}
```

- Explanation:
    - *AddScore(int amount)*: Adds the specified amount to the score and updates the score text.
    - *UpdateADABalance(int amount)*: Updates the ADA balance and updates the ADA balance text.
    - *UpdateScoreText() and UpdateADABalanceText()*: Helper methods to update the UI text elements.

Step 6: Save the Script
- Save the script in Visual Studio (File > Save or Ctrl+S).


Step 7: Attach the Script to the Canvas GameObject
- Select the Canvas GameObject in the Hierarchy window.
    - Drag the "UIManager" script from the Project window to the Canvas GameObject in the Hierarchy window.
    - Alternatively, you can click the "Add Component" button in the Inspector window, type "UIManager" in the search box, and select the script from the list.

Step 8: Link the Text Elements to the Script
- In the Inspector window, drag the "ScoreText" GameObject to the Score Text field of the UIManager component.
    - Drag the "ADABalanceText" GameObject to the ADA Balance Text field of the UIManager component.

Step 9: Update the Player and Collectible Scripts to Interact with the UI
- Update the PlayerController Script
- Open the "PlayerController" script in Visual Studio and add a reference to the UIManager.

```
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float speed = 5.0f;
    private UIManager uiManager;

    void Start()
    {
        uiManager = FindObjectOfType<UIManager>();
    }

    void Update()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
        transform.Translate(movement * speed * Time.deltaTime);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Collectible"))
        {
            uiManager.AddScore(10); // Add 10 points for each collectible
        }
    }
}
```

- Explanation:
    - *uiManager = FindObjectOfType<UIManager>()*: Finds the UIManager in the scene and assigns it to the uiManager variable.
    - *uiManager.AddScore(10)*: Adds 10 points to the score when the player collects an item.

- Open the "CollectibleItem" script in Visual Studio and modify it to interact with the UIManager.

```
using UnityEngine;

public class CollectibleItem : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            // Reward the player with ADA
            WalletManager walletManager = other.GetComponent<WalletManager>();
            if (walletManager != null)
            {
                walletManager.RewardPlayer();
            }

            // Update the ADA balance in the UI
            UIManager uiManager = FindObjectOfType<UIManager>();
            if (uiManager != null)
            {
                uiManager.UpdateADABalance(1); // Add 1 ADA for each collectible
            }

            // Destroy the collectible item
            Destroy(gameObject);
        }
    }
}
```

- Explanation:
    - *UIManager uiManager = FindObjectOfType<UIManager>()*: Finds the UIManager in the scene and assigns it to the uiManager variable.
    - *uiManager.UpdateADABalance(1)*: Adds 1 ADA to the balance when the player collects an item.

## Summary
By following these steps, you will have implemented a basic user interface in your game to display player information such as score and ADA balance. This enhances the player's experience by providing important feedback and information, making the game more engaging and interactive.

3.5 Implementing a User Interface (UI)

Game Mechanics

## Introduction
In this section, we will define conditions for game over and winning the game, and create corresponding UI elements to display these states. This will provide clear feedback to the player about their progress and the end of the game.

## Implementing Game Over and Win Conditions

Step 1: Create a Game Over UI Panel
- In the Hierarchy window, right-click on the Canvas GameObject and select UI > Panel. Name it "GameOverPanel".
    - Customize the panel's appearance in the Inspector window (e.g., background color, size).
    - Right-click on the GameOverPanel in the Hierarchy window and select UI > Text. Name it "GameOverText".
    - Customize the text component to display a game over message (e.g., "Game Over!").
    - Set the GameOverPanel's Active property to false in the Inspector window to hide it initially.

Step 2: Create a Win UI Panel
- Repeat the steps above to create a WinPanel and WinText, with a message like "You Win!".
- Set the WinPanel's Active property to false in the Inspector window to hide it initially.

Step 3: Create a New C# Script for Game Management
- In the Project window, right-click in the "Assets" folder, select Create > C# Script, and name it "GameManager".

Step 4: Edit the Script
- Open the script in Visual Studio and replace the contents with the following code:

```
using UnityEngine;

public class GameManager : MonoBehaviour
{
    public GameObject gameOverPanel;
    public GameObject winPanel;
    private bool isGameOver = false;
    private bool isGameWon = false;

    void Update()
    {
        if (isGameOver)
        {
            gameOverPanel.SetActive(true);
        }

        if (isGameWon)
        {
            winPanel.SetActive(true);
        }
    }

    public void GameOver()
    {
        isGameOver = true;
    }

    public void WinGame()
    {
        isGameWon = true;
    }
}
```

Explanation:
- *isGameOver and isGameWon*: Boolean flags to track the game state.
- *GameOver()*: Sets the isGameOver flag to true.
- *WinGame()*: Sets the isGameWon flag to true.
- *Update()*: Activates the appropriate UI panel based on the game state.

Step 5: Save the Script
- Save the script in Visual Studio (File > Save or Ctrl+S).

Step 6: Attach the Script to a GameObject
- Create an empty GameObject in the Hierarchy window and name it "GameManager".
    - Drag the "GameManager" script from the Project window to the GameManager GameObject in the Hierarchy window.
    - In the Inspector window, link the GameOverPanel and WinPanel GameObjects to the corresponding fields in the GameManager component.

Step 7: Update the Player and Collectible Scripts to Interact with the GameManager

- 7.1: Update the PlayerController Script
    - Open the "PlayerController" script in Visual Studio and add a reference to the GameManager.

```
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float speed = 5.0f;
    private UIManager uiManager;
    private GameManager gameManager;

    void Start()
    {
        uiManager = FindObjectOfType<UIManager>();
        gameManager = FindObjectOfType<GameManager>();
    }

    void Update()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
        transform.Translate(movement * speed * Time.deltaTime);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Collectible"))
        {
            uiManager.AddScore(10); // Add 10 points for each collectible
            if (uiManager.GetScore() >= 100) // Example win condition
            {
                gameManager.WinGame();
            }
        }
    }
}
```

- Explanation:
    - *gameManager = FindObjectOfType<GameManager>()*: Finds the GameManager in the scene and assigns it to the gameManager variable.
    - *if (uiManager.GetScore() >= 100)*: Checks if the player's score is 100 or more to trigger the win condition.

- 7.2: Update the CollectibleItem Script
    - Open the "CollectibleItem" script in Visual Studio and modify it to interact with the GameManager.

```
using UnityEngine;

public class CollectibleItem : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            // Reward the player with ADA
            WalletManager walletManager = other.GetComponent<WalletManager>();
            if (walletManager != null)
            {
                walletManager.RewardPlayer();
            }

            // Update the ADA balance in the UI
            UIManager uiManager = FindObjectOfType<UIManager>();
            if (uiManager != null)
            {
                uiManager.UpdateADABalance(1); // Add 1 ADA for each collectible
            }

            // Destroy the collectible item
            Destroy(gameObject);
        }
    }
}
```

Step 8: Test the Game Over and Win Conditions
- Click the "Play" button in the Unity toolbar to run your game.
- Collect items to increase the score and trigger the win condition.
- Implement a scenario to trigger the game over condition (e.g., falling off the platform).

## Summary
By following these steps, you will have implemented game over and win conditions in your game, providing clear feedback to the player about their progress and the end of the game. This enhances the overall gameplay experience and adds a sense of achievement for the player.

```
using UnityEngine;

public class AudioManager : MonoBehaviour
{
    public AudioSource backgroundMusicSource;
    public AudioSource soundEffectsSource;
    public AudioClip collectibleSound;
    public AudioClip gameOverSound;
    public AudioClip winSound;

    void Start()
    {
        PlayBackgroundMusic();
    }

    public void PlayBackgroundMusic()
    {
        if (backgroundMusicSource != null)
        {
            backgroundMusicSource.Play();
        }
    }

    public void PlaySoundEffect(AudioClip clip)
    {
        if (soundEffectsSource != null && clip != null)
        {
            soundEffectsSource.PlayOneShot(clip);
        }
    }
}
```

- Explanation:
    - *PlayBackgroundMusic()*: Plays the background music when the game starts.
    - *PlaySoundEffect(AudioClip clip)*: Plays a sound effect using the provided audio clip.

Step 6: Save the Script
- Save the script in Visual Studio (File > Save or Ctrl+S).


Step 7: Attach the Script to a GameObject
- Create an empty GameObject in the Hierarchy window and name it "AudioManager".
    - Drag the "AudioManager" script from the Project window to the AudioManager GameObject in the Hierarchy window.
    - In the Inspector window, link the BackgroundMusic and SoundEffects GameObjects to the corresponding fields in the AudioManager component.
    - Assign the appropriate audio clips (e.g., collectibleSound, gameOverSound, winSound) to the corresponding fields in the AudioManager component.

Step 8: Update the Player and Collectible Scripts to Play Sound Effects
- 8.1: Update the PlayerController Script
    - Open the "PlayerController" script in Visual Studio and add a reference to the AudioManager.

```
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float speed = 5.0f;
    private UIManager uiManager;
    private GameManager gameManager;
    private AudioManager audioManager;

    void Start()
    {
        uiManager = FindObjectOfType<UIManager>();
        gameManager = FindObjectOfType<GameManager>();
        audioManager = FindObjectOfType<AudioManager>();
    }

    void Update()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
        transform.Translate(movement * speed * Time.deltaTime);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Collectible"))
        {
            uiManager.AddScore(10); // Add 10 points for each collectible
            audioManager.PlaySoundEffect(audioManager.collectibleSound); // Play collectible sound
            if (uiManager.GetScore() >= 100) // Example win condition
            {
                gameManager.WinGame();
                audioManager.PlaySoundEffect(audioManager.winSound); // Play win sound
            }
        }
    }
}
```
