The document provides an overview of the Unity basics for creating a new project, understanding the user interface, and beginning game development in Unity. Key points include choosing 2D or 3D, importing asset packages, the main windows like Hierarchy, Project, Scene and Game, and the top toolbar options. It also covers creating scripts, adding basic assets, components like Rigidbody and Colliders, and level design fundamentals.

1. Unity basics

2. Creating new project
Choose a name
and save location
for your project
Select if you want
2D or 3D
You can also
import asset
packages starting
your project
• Asset packages can be
downloaded from the
Unity asset store
Click the create
buttonto start
making your game

4. User interface
• Hierachy window
• Has all the assets in game (such as
graphics, models, music etc.) in
written
• It's good to categorize all the
assets in the level and stackthose
assets so that it'll be easier to find
them in hierarchy when you need
to

5. User interface
• Project window
• Has all the assets imported into the project
• Including the plug-ins from asset store

6. User interface
• Scene window
• You can modify the game in this
view
• All the assets are shown as the
would be in the game

7. User interface
• Game window
• You can test your game
• On the top of the UI there are
buttons for playing, stopping and
pausing the test

8. User interface
• Inspector window
• You can modify a chosen object in here
• Depending from the object, there are
different elements that you can modify

9. Top toolbar
File
• Create, save and
open new scenes
and projects
• Build settings are
needed for
compiling the game
and changing
settings like level
order or platform
Assets
• Create new assets
such as physic
materials and new
scripts
• You can also import
asset packages from
here
GameObject
• Create new objects
such as cameras,
sprites, lights, basic
3D shapes and UI
elements
• You can also create
empty game objects
from here

10. Top toolbar
Window
• Access and rearrange new
windows
• Animation and animator windows
can be activated from here
• Occlusion culling and other
windows that are for optimizing
the game can be found in the
window tab

11. Creating a game
Scripts
To create new script right click in the project windowand select new script
You can also create new script from the inspector windowwhen you haveselected and object
from yourgame
Unityuses C# as the programminglanguage
Scripts will open in Visual studio in which you can write the code
Assets
First,you're going to need some assets for the game
These can be just white boxes for testingpurposes
You can later replace the test objects with actual graphics

12. Creating a game
Adding
assets
You can drag and drop assets from the project window to the
hierarchy or scene window
Change the position of the objects with a move tool or
manually writing the coordinates in the inspector window
You can add new components toyour assets in the inspector
window
• These include in example different colliders, rigidbody and scripts

13. Creating a game
Components
Rigidbody is a componentthat gives physics properties to
your game assets
• Rigidbody has a mass and gravity components effecting how the game
object will behave in the game world
Change the position of the objects with a move tool or
manually writing the coordinates in the inspector window
Colliders make objects collide with each other
• Collider can also be a trigger which makes the collider transparent
• Trigger colliders are useful for triggering events when you don't want game
assets to collide with each other

14. Creating a game
Level
design
Create a layout of the level this can be done from top down
or side perspective
Add starting and ending points
Design routes that the player can progress
Add obstacles and enemies if there are any
Add any interactions that the game has for example pressing
buttons, destroying walls or interacting with NPCs (non-
playable characters)
