Game Development Development Tutorials, Guides & Insights

• Frameworks and libraries like React, Angular, and Vue.js make it easier to build Single Page Applications (SPAs).
• Examples: Gmail, Netflix, Trello.

• With Node.js, JavaScript powers the back-end to handle databases, APIs, and server logic.
• Examples: REST APIs, real-time collaboration tools like Google Docs.

Let’s first create the game logic for tic-tac-toe.

• Open Unity Hub and click on "New Project."
• Choose the "3D" template (you can use 2D if you prefer) and name your project, for example, "RealTimeMultiplayerGame."
• Click "Create" to generate the new project.

• Go to Window > Package Manager.
• Search for "Netcode for GameObjects" (or any other networking package of your choice, like Photon or Mirror).
• Click "Install" to add it to your project.

Create a scriptable object for defining item properties.

using UnityEngine;

// Define the base item as a scriptable object
[CreateAssetMenu(fileName = "NewItem", menuName = "Inventory/Item")]
public class Item : ScriptableObject
{
    public string itemName;
    public Sprite icon;
    public bool isStackable;
    public int maxStackSize = 1;

    public virtual void Use()
    {
        Debug.Log($"Using {itemName}");
    }
}

using UnityEngine;

// Basic player controller for Unity
[RequireComponent(typeof(CharacterController))]
public class PlayerController : MonoBehaviour
{
    [Header("Player Settings")]
    public float moveSpeed = 5f;
    public float jumpHeight = 2f;
    public float gravity = -9.81f;
    public Transform cameraTransform;

    private CharacterController characterController;
    private Vector3 velocity;
    private bool isGrounded;

    void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    void Update()
    {
        MovePlayer();
        RotateCamera();
    }

    void MovePlayer()
    {
        // Check if the player is on the ground
        isGrounded = characterController.isGrounded;
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f; // A small negative value to keep the player grounded
        }

        // Get input for movement
        float moveX = Input.GetAxis("Horizontal");
        float moveZ = Input.GetAxis("Vertical");

        // Calculate movement direction
        Vector3 move = transform.right * moveX + transform.forward * moveZ;
        characterController.Move(move * moveSpeed * Time.deltaTime);

        // Jumping logic
        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }

        // Apply gravity
        velocity.y += gravity * Time.deltaTime;
        characterController.Move(velocity * Time.deltaTime);
    }

    void RotateCamera()
    {
        // Get input for mouse movement
        float mouseX = Input.GetAxis("Mouse X");
        float mouseY = Input.GetAxis("Mouse Y");

        // Rotate player along the y-axis
        transform.Rotate(Vector3.up * mouseX);

        // Rotate camera along the x-axis
        cameraTransform.Rotate(Vector3.left * mouseY);
    }
}

• Animation Integration: Add animator components and trigger animations based on movement and jump states.
• Advanced Physics: Integrate more complex physics interactions, such as slopes or surface friction.
• Networking: Adapt the controller for multiplayer environments using Unity’s networking solutions.
