Unity

Popular cross-platform game engine.

Overview

Unity is a cross-platform game engine developed by Unity Technologies, widely used for creating 2D, 3D, VR, and AR games.

Features

• Cross-platform development
• C# scripting
• Visual scripting with Bolt
• Asset Store
• Physics engine
• Rendering pipeline

Getting Started

// Create new 3D project in Unity
// Create C# script
// PlayerController.cs
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float moveSpeed = 5f;
    public float rotateSpeed = 100f;
    
    private Rigidbody rb;
    
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    
    void Update()
    {
        // Rotation
        float horizontalInput = Input.GetAxis("Horizontal");
        transform.Rotate(Vector3.up, horizontalInput * rotateSpeed * Time.deltaTime);
        
        // Movement
        float verticalInput = Input.GetAxis("Vertical");
        Vector3 movement = transform.forward * verticalInput * moveSpeed * Time.deltaTime;
        rb.MovePosition(transform.position + movement);
    }
}

Basic Example

// GameManager.cs
using UnityEngine;
using UnityEngine.UI;

public class GameManager : MonoBehaviour
{
    public Text scoreText;
    private int score = 0;
    
    public void AddScore(int points)
    {
        score += points;
        UpdateScoreText();
    }
    
    private void UpdateScoreText()
    {
        scoreText.text = "Score: " + score.ToString();
    }
    
    void Start()
    {
        UpdateScoreText();
    }
}
