Beginner 2D UFO Game 1 of 9: Introduction - Unity Official Tutorials

In this beginner assignment we're going to make a

very simple but playable 2D game

to use many of the basic concepts

from the beginner tutorial modules.

We'll be making a 2D UFO game

where we'll be collecting gold nuggets.

We'll see how to create new game objects,

add components to these game objects,

set the values on their properties,

and position these game objects in the scene

to create a game.

In our game the player will control

a UFO flying around the game board in a

top-down 2D view.

We'll move the UFO using physics and forces.

We'll look at the input from the player

through the keyboard and we'll use those inputs

to apply forces to the UFO,

making it move in our scene.

We'll see how to detect contact between

the UFO and the pickup game objects

and use these events to collect

the pickup game objects.

When we've done we'll have made a simple

UFO game where the player controls the

UFO with the keyboard, picks up and counts

special collectable objects,

displays the current count,

and ends the game when all of the

game objects have been picked up.

To complete this project we'll use custom

created 2D art assets

which can be downloaded from the

Unity Asset Store.

Let's begin by creating a new project.

First open the Unity editor

if you haven't done that already.

You can create a new project by

choosing File - New Project.

This will bring us to the home screen.

On the home screen you can create a

new project either by hitting the

blue Create New Project button

in the centre of the window,

or by clicking the New button

at the top of the window.

The first thing that we need to do is

to give our project a name,

I'm going to call the project UFO Game.

The next thing we need to do is set the

destination, or path, to our new project.

I'm going to put this new project on my desktop.

You'll see we have a choice

to set the project preferences

to either 3D or 2D mode.

Since we're working in 2D

I'm going to click 2D.

This will set the preferences for the Unity editor

to useful defaults for creating 2D game.s

For more information on working in 2D,

please see the information linked below.

Now click the Create Project button

to create our new project.

Unity will create a new empty scene

for us to work in.

The first thing we'll need to do is to download

and import our art assets

from the Unity Asset Store.

To access the Asset Store choose

Window - Asset Store.

Or use the keyboard shortcut

command + 9 on mac,

or control + 9 on windows.

The Asset Store is a service that

Unity Technologies provides

where creators can both buy and sell

assets to make games.

These include art, music, scripts, effects,

all the way up to complete games and projects.

Unity also publishes content

to the Asset Store, including teaching

projects like this one to help

you learn how to make games.

By default the Asset Store is

opened as a docked tab.

Let's undock the tab so that we can

expand the window.

In the upper-right corner of

the expanded Asset Store window

we'll see a listing of asset categories.

At the bottom we should find

Unity Essentials.

Expand this category and we'll find

a subcategory called Sample Projects.

Within Sample Projects we'll find

an item called 2D UFO tutorial.

Click on the item title to open it.

Once the page loads we'll see a

download button in the upper-left corner.

Click on the Download button to begin

downloading the assets.

The Download button will be replaced

by the percentage of the download completed

once we click on it.

Once the download is complete we'll see

a dialogue labelled Importing Complete Project.

This warns us that importing a

complete project will overwrite

our current project settings.

In this case, because we've just created a

new project this is fine.

Click the Import button to continue.

Next we'll be given a choice

of which assets we would like to

import in to our project.

The default is All, which is what we want,

so go ahead and click Import.

Close the Asset Store window.

We now have our new project with our assets imported.

And the default new empty scene open.

Before creating anything in the new scene

we need to save our scene.

We can save our scene by choosing

File - Save Scene,

or by using the keyboard shortcut

command + S on mac,

or control + S on windows.

I'm going to save this scene

in the Assets directory in the

folder called Scenes.

I'm going to call the scene Main.

We can now see in our Scenes folder

the scene called Main.

It's worth noting that the

Completed, Prefabs, Scenes, Scripts

and Sprites folders

were all created when we imported our asset package.

The Completed folder contains

a completed version of the project,

which you can refer to if you get stuck.

Great, that's the end of our first lesson.

In our next lesson we're going to lay out our play field.
