How to Build a 2D Tapping Game in Unity

This tutorial shows you how to build a simple 2D tapping game in Unity, similar to "Tapping Bugs," where players tap moving insects to score points. The game is easily adaptable for Android, iOS, and WebGL platforms.

Key Concepts:

• Creating a Unity project with a 2D game scene, canvas, and GUI elements.
• Using UnityScript (or C#) to control game logic.
• Implementing core game mechanics: insect movement, score tracking, and lives management.
• Managing multiple scenes: main game, game over, and menu.

Getting Started:

1. Ensure you have the latest Unity version installed.
2. Create a new 2D Unity project.
3. Import necessary assets (background image, insect sprite – ant_1.png, button images). The provided assets can be found here.

Scene Setup:

1. Import the background image and adjust its size to fit your screen (e.g., 800x1280 portrait).
2. Import the insect sprite (ant_1.png), scale it appropriately, and add a Circle Collider 2D component.
3. Create a Canvas, setting the Render Mode to Screen Space - Camera, assigning your Main Camera, and adjusting Plane Distance. Set the UI Scale Mode in the Canvas Scaler to Scale With Screen Size and Screen Match Mode to Expand.
4. Add UI Text elements for displaying the "Score" and "Lives" counters.

Scripting (UnityScript):

Create a new JavaScript file (AntScript.js) with the following variables:

<code class="language-javascript">var ant : GameObject;
var scoreNumber : int;
var livesNumber : int;
var scoreText : GameObject;
var livesText : GameObject;
var walkingSpeed : double;</code>

Start() Function:

<code class="language-javascript">function Start () {
    ant = GameObject.Find("Ant");
    scoreText = GameObject.Find("Score");
    livesText = GameObject.Find("Lives");

    walkingSpeed = 0.0;
    livesNumber = 3;
    scoreNumber = 0;

    livesText.GetComponent(UI.Text).text = "Lives Remaining: " + livesNumber;
    scoreText.GetComponent(UI.Text).text = "Score: " + scoreNumber;

    ant.transform.position.x = generateX();
    ant.transform.position.y = generateY();
}</code>

generateX() and generateY() Functions:

These functions generate random x and y coordinates for the insect's position within the screen bounds. Adjust the ranges to match your screen size.

<code class="language-javascript">function generateX(){
    var x = Random.Range(-2.54,2.54);
    return x;
}

function generateY(){
    var y = Random.Range(-4.0,3.8);
    return y;
}</code>

Update() Function:

<code class="language-javascript">function Update () {
    // ... (Movement and game over logic - see original for details)
}</code>

OnMouseDown() Function:

<code class="language-javascript">function OnMouseDown(){
    generateCoordinates();
    walkingSpeed += 0.01;
    scoreNumber++;
    scoreText.GetComponent(UI.Text).text = "Score: " + scoreNumber;
}</code>

Game Over and Menu Scenes:

Create separate scenes for the "Game Over" and "Menu" screens, including UI elements (buttons, text) and scripts to handle scene loading and game restarting. Use a separate script (Functions.js) to manage these actions (see original for details).

Remember to attach the AntScript.js script to the "Ant" GameObject and the Functions.js script to the appropriate buttons in the Game Over and Menu scenes. The complete code can be found on GitHub (link provided in the original).
