[ TUTO ] Unity débutant : apprendre à créer des Jeux-Video avec Unity : les bases

Introduction

This tutorial is designed for beginners who want to learn the basics of game development using Unity. Unity is a powerful game engine that enables developers to create 2D and 3D games. By following this guide, you will gain foundational knowledge and skills to start creating your own video games.

Step 1: Setting Up Your Unity Environment

• Download and Install Unity

  • Go to the Unity website and download the latest version of Unity Hub.
  • Install Unity Hub and use it to install the latest version of the Unity Editor.

• Create a New Project

  • Open Unity Hub.
  • Click on the "New Project" button.
  • Choose a template (2D or 3D based on your game idea).
  • Name your project and select a location to save it, then click "Create."

Step 2: Understanding the Unity Interface

• Familiarize Yourself with Key Panels

  • Scene View: This is where you build your game environment.
  • Game View: This shows what the player will see during gameplay.
  • Hierarchy Panel: Displays all objects in your scene.
  • Inspector Panel: Allows you to view and edit properties of selected objects.
  • Project Panel: Contains all your assets like images, scripts, and models.

• Navigating the Scene View

  • Use the right mouse button to look around.
  • Use the middle mouse button to pan.
  • Scroll to zoom in and out.

Step 3: Creating Game Objects

• Add 3D Objects

  • Right-click in the Hierarchy Panel.
  • Select "3D Object" and choose an object (e.g., Cube, Sphere).

• Modify Object Properties

  • Select the object in the Hierarchy.
  • Use the Inspector Panel to change its position, rotation, and scale.

Step 4: Adding Components

• What are Components?

  • Components are the building blocks of GameObjects that define their behavior (e.g., Rigidbody for physics, Collider for collision detection).

• Adding a Rigidbody

  • Select your GameObject.
  • In the Inspector, click "Add Component."
  • Search for and select "Rigidbody" to add physics behaviors.

Step 5: Creating a Simple Script

• Writing Your First Script

  • In the Project Panel, right-click and create a new C# script (e.g., "PlayerController").
  • Double-click to open it in your code editor.

• Basic Script Example

  using UnityEngine;
  
  public class PlayerController : MonoBehaviour {
      void Update() {
          float move = Input.GetAxis("Horizontal");
          transform.Translate(move * Time.deltaTime, 0, 0);
      }
  }
  

• Attach the Script

  • Drag the script from the Project Panel onto your GameObject in the Hierarchy.

Step 6: Testing Your Game

• Run Your Game

  • Click the "Play" button at the top of the Unity window.
  • Observe how the GameObject responds to your inputs.

• Debugging

  • If something doesn’t work, check the Console window for error messages and ensure all components are correctly attached.

Conclusion

You have now learned the foundational steps to create your first game in Unity, including setting up the environment, understanding the interface, creating GameObjects, adding components, scripting basic movements, and testing your game.

As you continue your journey in game development, explore additional resources such as online courses and tutorials. Consider leveraging platforms like Udemy or YouTube channels dedicated to Unity for more advanced topics and techniques. Happy gaming!
