Number Puzzle Game (Unity + Admob + Leaderboard)

Introduction

The Number Puzzle Game is a popular mobile game that challenges players to solve a series of number puzzles to progress through levels. In this tutorial, we will guide you on how to create a complete Number Puzzle Game using Unity, AdMob for monetization, and a leaderboard to track players' progress.

Step 1: Setting up the Project

To start, create a new Unity project and choose the "3D" template. Name your project "Number Puzzle Game" and set the project location.

Step 2: Creating the Game Mechanics

The game mechanics involve generating a random number puzzle, allowing the player to input their answer, and checking if the answer is correct. To implement this, create a new C# script and attach it to a GameObject in your scene. Name the script "NumberPuzzle".

Here is the code for the NumberPuzzle script:

using UnityEngine;
using System.Collections.Generic;

public class NumberPuzzle : MonoBehaviour
{
    public int puzzleSize = 4; // size of the puzzle
    public int maxNumber = 10; // maximum number in the puzzle
    public int timeLimit = 30; // time limit for the player to solve the puzzle

    private int[] puzzleNumbers; // array to store the puzzle numbers
    private int[] playerAnswer; // array to store the player's answer
    private bool isSolved = false; // flag to check if the puzzle is solved

    void Start()
    {
        // generate the puzzle numbers
        puzzleNumbers = new int[puzzleSize * puzzleSize];
        for (int i = 0; i < puzzleSize * puzzleSize; i++)
        {
            puzzleNumbers[i] = Random.Range(1, maxNumber + 1);
        }

        // shuffle the puzzle numbers
        System.Random rand = new System.Random();
        for (int i = 0; i < puzzleSize * puzzleSize; i++)
        {
            int j = rand.Next(i, puzzleSize * puzzleSize);
            int temp = puzzleNumbers[i];
            puzzleNumbers[i] = puzzleNumbers[j];
            puzzleNumbers[j] = temp;
        }
    }

    void Update()
    {
        // check if the puzzle is solved
        if (isSolved)
        {
            // if the puzzle is solved, display the result and reset the puzzle
            DisplayResult();
            ResetPuzzle();
        }
    }

    public void SolvePuzzle(int[] answer)
    {
        // check if the answer is correct
        playerAnswer = answer;
        if (IsAnswerCorrect())
        {
            isSolved = true;
        }
    }

    bool IsAnswerCorrect()
    {
        // check if the player's answer matches the puzzle numbers
        for (int i = 0; i < puzzleSize * puzzleSize; i++)
        {
            if (playerAnswer[i]!= puzzleNumbers[i])
            {
                return false;
            }
        }
        return true;
    }

    void DisplayResult()
    {
        // display the result of the puzzle
        Debug.Log("Congratulations! You solved the puzzle!");
    }

    void ResetPuzzle()
    {
        // reset the puzzle
        puzzleNumbers = new int[puzzleSize * puzzleSize];
        for (int i = 0; i < puzzleSize * puzzleSize; i++)
        {
            puzzleNumbers[i] = Random.Range(1, maxNumber + 1);
        }
        isSolved = false;
    }
}

Step 3: Creating the UI

Create a new UI canvas and add a panel to it. Name the panel "PuzzlePanel". Add a text field to the panel to display the puzzle numbers and a button to allow the player to input their answer.

Here is the code for the PuzzlePanel script:

using UnityEngine;
using UnityEngine.UI;

public class PuzzlePanel : MonoBehaviour
{
    public Text puzzleText; // text field to display the puzzle numbers
    public InputField answerInput; // input field to allow the player to input their answer
    public Button submitButton; // button to submit the answer

    private NumberPuzzle puzzle; // reference to the NumberPuzzle script

    void Start()
    {
        // get the NumberPuzzle script
        puzzle = GetComponent<NumberPuzzle>();

        // display the puzzle numbers
        puzzleText.text = "";
        for (int i = 0; i < puzzle.puzzleSize * puzzle.puzzleSize; i++)
        {
            puzzleText.text += puzzle.puzzleNumbers[i].ToString() + "n";
        }
    }

    public void SubmitAnswer()
    {
        // get the player's answer
        string answer = answerInput.text;

        // convert the answer to an array of integers
        int[] answerArray = new int[puzzle.puzzleSize * puzzle.puzzleSize];
        for (int i = 0; i < puzzle.puzzleSize * puzzle.puzzleSize; i++)
        {
            answerArray[i] = int.Parse(answer.Substring(i * 2, 2));
        }

        // solve the puzzle
        puzzle.SolvePuzzle(answerArray);
    }
}

Step 4: Implementing AdMob

To implement AdMob, create a new AdMob plugin for Unity and follow the instructions to set up the plugin.

Here is an example of how to implement AdMob in your game:

using UnityEngine;
using GoogleMobileAds;

public class AdMob : MonoBehaviour
{
    private InterstitialAd interstitial; // interstitial ad

    void Start()
    {
        // initialize the AdMob plugin
        MobileAds.Initialize(initStatus => {
            // load the interstitial ad
            LoadInterstitialAd();
        });
    }

    void LoadInterstitialAd()
    {
        // load the interstitial ad
        interstitial = new InterstitialAd("YOUR_AD_UNIT_ID");
        interstitial.LoadAd(new AdRequest.Builder().Build());
    }

    public void ShowInterstitialAd()
    {
        // show the interstitial ad
        if (interstitial.IsLoaded())
        {
            interstitial.Show();
        }
    }
}

Step 5: Implementing Leaderboard

To implement a leaderboard, create a new Google Play Games plugin for Unity and follow the instructions to set up the plugin.

Here is an example of how to implement a leaderboard in your game:

using UnityEngine;
using GooglePlayGames;

public class Leaderboard : MonoBehaviour
{
    private LeaderboardScore leaderboardScore; // leaderboard score

    void Start()
    {
        // initialize the Google Play Games plugin
        PlayGamesPlatform.InitializeInstance();
        PlayGamesPlatform.DebugLogEnabled = true;

        // load the leaderboard score
        leaderboardScore = PlayGamesPlatform.Instance.GetLeaderboardScore();
    }

    public void SubmitScore(int score)
    {
        // submit the score to the leaderboard
        leaderboardScore.SubmitScore(score, "YOUR_LEADERBOARD_ID");
    }
}

Step 6: Integrating the Game Mechanics with AdMob and Leaderboard

To integrate the game mechanics with AdMob and leaderboard, create a new C# script and attach it to a GameObject in your scene. Name the script "GameController".

Here is the code for the GameController script:

using UnityEngine;
using UnityEngine.UI;
using GoogleMobileAds;
using GooglePlayGames;

public class GameController : MonoBehaviour
{
    public NumberPuzzle puzzle; // reference to the NumberPuzzle script
    public AdMob adMob; // reference to the AdMob script
    public Leaderboard leaderboard; // reference to the Leaderboard script

    private int score = 0; // score for the player

    void Start()
    {
        // initialize the game mechanics
        puzzle.Start();
    }

    void Update()
    {
        // check if the puzzle is solved
        if (puzzle.isSolved)
        {
            // if the puzzle is solved, display the result and reset the puzzle
            DisplayResult();
            ResetPuzzle();
        }
    }

    void DisplayResult()
    {
        // display the result of the puzzle
        Debug.Log("Congratulations! You solved the puzzle!");
    }

    void ResetPuzzle()
    {
        // reset the puzzle
        puzzle.ResetPuzzle();
    }

    public void SolvePuzzle(int[] answer)
    {
        // check if the answer is correct
        if (puzzle.IsAnswerCorrect())
        {
            // if the answer is correct, increase the score
            score += 10;
            // display the score
            Debug.Log("Your score: " + score);
            // submit the score to the leaderboard
            leaderboard.SubmitScore(score);
        }
        else
        {
            // if the answer is incorrect, display an error message
            Debug.Log("Incorrect answer!");
        }
    }

    public void ShowInterstitialAd()
    {
        // show the interstitial ad
        adMob.ShowInterstitialAd();
    }
}

Step 7: Testing the Game

To test the game, run the game on a device or emulator and play through the levels. Make sure to test the game mechanics, AdMob, and leaderboard integration.

Conclusion

In this tutorial, we have created a complete Number Puzzle Game using Unity, AdMob for monetization, and a leaderboard to track players' progress. We have implemented the game mechanics, AdMob, and leaderboard integration using C# scripts. We have also tested the game to ensure that it works as expected.
