Summary  
This chapter explains how to manipulate a component-based scene graph by creating, selecting, and organizing hierarchical objects, then using transformation tools to position, rotate, and scale them while editing their component properties via an inspector.  

General domain of usage  
Game development

When you open Unity, you'll see several **panels.** Each panel has a specific role, and together they let you build and edit games.

The main panels you'll use are:
 **Hierarchy, Scene, Game, Inspector, Project, and Console**

## Hierarchy - A list of all Game Objects in the current scene.

What you use it for:

- Creating new objects;
- Selecting objects;
- Deleting objects.


## Scene View - A visual workspace where you arrange objects in the scene.

**What you use it for:**
- Positioning objects;
- Moving, rotating, and scaling objects;
- Navigating the level layout.
**\*Essential Shortcuts**
- Move Tool: `W`
- Rotate Tool: `E`
- Scale Tool: `R`


## Game View - What the player actually sees through the camera.

**What you use it for:**
- Previewing gameplay;
- Checking camera framing;
- Testing how the game looks while running.


## Inspector - A panel that shows details of the currently selected object.

**What you use it for:**
- Editing components;
- Changing position, rotation, and scale;
- Adjusting visual properties (like sprite color).


## Project Tab - A file browser for your entire Unity project.
**What you use it for:**
- Managing scenes, sprites, and scripts;
- Creating folders to stay organized;
- Importing assets.

**\*Good practice:**
 
Create folders like:

- `Scenes`;
- `Sprites`;
- `Scripts`.


## Console - A message log from Unity.
**What you use it for:**
- Viewing errors;
- Seeing warnings and debug messages.


## Play Mode - A test mode that runs your game inside the editor.



**Very important:**

Changes made during Play Mode are **temporary** and reset when you stop.


Where can you see a list of all Game Objects in the current scene?

Which panel shows what the player actually sees during gameplay?

Where do you change an object’s position, rotation, and scale using exact values?

What happens to changes made while the game is in Play Mode?

You'll learn how to make your first complete game in Unity while building the core skills needed to prototype many different game ideas.

You will install Unity and get familiar with the Unity Editor interface. You will learn how to navigate the main panels, understand the layout of the editor, and explore the basic tools used to build and manage scenes. By the end of this section, you will be comfortable moving around the editor and ready to start creating your first Unity projects.

In this section, you will explore how components work in Unity and how they are managed through the Inspector. You will learn how GameObjects gain functionality by attaching components, how to view and modify their properties, and how the Inspector helps control behavior, visuals, and physics within a scene. By the end of this section, you will understand the core component-based workflow used in Unity.


Learn the core principles of object-oriented programming using C#. You will explore how classes, objects, properties, and methods work together to structure game logic in Unity. The section introduces key concepts such as encapsulation, inheritance, and code organization, helping you understand how to write reusable and maintainable scripts for your projects.


You will expand your C# programming skills by implementing additional gameplay mechanics. You will learn how to write more advanced scripts, control object behavior, and create interactive systems that enhance your game. By the end of this section, you will be able to use C# to build more dynamic and engaging mechanics in Unity.

In this section, you will explore the concept of game feel and how visual and responsive feedback improves the player experience. You will learn how to use post-processing effects to enhance the look of your game and implement feedback systems that make player actions feel more responsive and satisfying. By the end of this section, you will understand how small visual and interaction details can significantly improve the overall feel of a game.

In this section, you will learn the fundamentals of creating user interfaces in Unity. You will explore how to build and organize UI elements such as panels, text, and buttons, and understand how they interact with the game and the player. By the end of this section, you will be able to design simple and functional interfaces that improve usability and player interaction.
