Alright, ready to start building
your first game?
0:05
Let's go!
0:08
First things first, notice
this little white box in the scene window?
0:09
This represents our camera's viewport,
meaning what the player will see.
0:13
If I squish and stretch this window,
see how the box changes shape as well?
0:18
Well that's no good.
0:22
We don't want the viewport changing shape.
0:23
Let's address this by checking
the target resolution for our camera.
0:26
Since we're building this
for our computers and not a mobile device
0:30
for example, I think
1080p is a good resolution to go with.
0:33
Let's open the game window and see here
where it says Free Aspect.
0:37
If you click here, you will see
0:42
we'll open some other default resolutions
you can choose from.
0:43
For example, if you'd to build for 4K,
0:47
you can select this 4K UHD option here.
0:49
You can even create your own custom sizes
by clicking this plus icon at the bottom.
0:52
I feel that 1080p
is still a commonly used resolution
0:57
for monitors,
and just so we're all on the same page
1:00
throughout this
project, let's select that.
1:03
This is typically the
1:06
first thing I do in a new project.
1:07
Now if I squish and stretch this window,
the aspect ratio remains the same.
1:10
Awesome.
1:15
I'm going to move these bottom tools here
1:17
and just pin them up top
to create some more room.
1:19
You don't need to do this though.
1:22
Alright, let's create our first game
object that will be our player.
1:25
To create a new game object, we just have
to right click in our hierarchy window
1:28
and we'll see all sorts of objects
we can make down here.
1:32
Let's go to 2D object,
1:37
then sprites,
and we'll see some basic shapes here.
1:39
Let's create a circle.
1:43
You can see in our scene window,
it's given us a white circle object
1:46
In the inspector we see this game
object comes with two components
1:50
a transform and a sprite renderer.
1:53
Up top here is a field where we can edit
the name.
1:57
Let's rename this circle to Player
and hit Enter or Return.
1:59
One thing to note is every single game
2:05
object in Unity has a transform component.
2:07
This tells Unity its position, rotation
and scale in our scene.
2:10
We can type in values into these boxes
to adjust
2:15
things.
2:18
Also, if we hover over one of these X,
2:21
Y, or Z labels, we'll get this drag icon.
2:24
We can click and drag side to side
to adjust things this way as well.
2:27
In 2D, the X axis
2:32
represents horizontal, or side to side,
2:33
the Y axis represents vertical,
or top to bottom,
2:36
and the Z, or Zed, which would normally
determine depth, meaning how close or far
2:40
from the camera the object is, is not
used all that much in 2D.
2:45
We do typically use the Z rotation
in 2D though.
2:49
My preferred way to change an object's
position is with the Move tool.
2:53
You can click this icon here,
or use the keyboard
2:57
shortcut W,
and you'll see these arrows here.
3:00
Clicking and dragging
the green changes the Y,
3:03
the red changes the X,
3:08
and if we click and drag in this box,
we can have free control.
3:10
I'm going to right-click on the component
name here and click Reset.
3:14
This will zero it out.
3:19
Notice the position
of this circle is 0, 0, 0
3:21
and it's directly
in the center of the screen.
3:24
If we drag the X position to the left,
3:27
the object will move left
and the numbers go negative.
3:30
Likewise, to the right of 0 is positive.
3:33
Same goes for the Y axis.
3:36
Going up is positive and down is negative.
3:38
Now there are other tools here as well.
3:41
We have the view tool,
which I never really use
3:46
as we get the same functionality
by clicking and holding down
3:48
the scroll wheel of the mouse.
3:51
It helps us move
3:54
around in our scene view. Also note,
if you see me zooming in and out,
3:54
I'm rolling the scroll wheel
on my mouse as well.
3:59
Then there's the rotate tool,
where we can click and drag
4:02
these axis lines to adjust the transforms
rotation.
4:04
You can see the values
4:10
changing up in the inspector.
4:11
I'm going to reset this again.
4:14
There's the scale tool
which does the same with its scale.
4:19
Clicking and dragging the center box
adjusts all three axes together.
4:22
I'm going to use Ctrl-Z or Cmd-Z on Mac
4:27
to undo this.
4:29
The Rect tool is handy
as it allows us to manipulate the position
4:33
and scale together
by clicking and dragging these dots
4:36
or outlines.
4:40
Holding Shift while doing this links
4:43
all of the scale axes
together to keep its shape.
4:44
And you can also click in the image
and move it around with this too.
4:47
Lastly, there's the
4:52
Transform tool, which combines
all of these into one place.
4:53
I haven't gotten proficient
with this one yet to be honest.
4:57
I switch between the Move and Rect tool
all the time though.
5:00
Conveniently, the keyboard shortcuts
for all of these is QWERTY.
5:04
So it's very easy to remember.
5:08
Q-W-E-R-T-Y.
5:10
Alright, moving on.
5:13
The sprite renderer component does
what its name suggests.
5:17
It renders a sprite,
or image, for our object,
5:20
and right now it's using a Unity built-in
sprite named Circle.
5:24
We'll change this to Mike the Frog later
on, don't worry.
5:28
For now,
5:31
let's just get the game working before
worrying about making it look all fancy.
5:31
For now, we don't need to worry
about these other properties.
5:36
We'll come back to some later on,
but every component has many adjustable
5:38
properties, and I don't want this course
to be overwhelming. I'd like it to be fun.
5:42
So we'll work with what we need as we need it.
5:46
I'll be leaving helpful links in the teacher's
notes below if you'd like to read further
5:49
about any of these components
though. So always check down there.
5:53
Up top here we have a play button.
This will let us test
5:57
our game and automatically
bring the game window into view.
6:00
Let's see what happens
when we we play our game.
6:04
We're waiting...
we're waiting...
6:08
Okay.
6:12
Well, not much.
6:13
But this is because
we simply haven't told Unity
6:15
to do anything with this game object yet,
6:17
besides put it in this position
and give it this sprite.
6:19
Let's click stop.
6:23
And before we do anything else,
6:25
there's a nifty little trick
that I wish I knew earlier in my journey.
6:26
Did you notice the time it took to enter
play mode,
6:30
we can cut this down significantly.
6:33
Let's go to Edit,
6:35
Project Settings,
6:39
and click on Editor.
6:43
Let's scroll down near the bottom
and right here where it says Enter
6:45
Play Mode Settings.
6:48
Let's change this to
Do Not Reload Domain or Scene.
6:50
For this small game we're making,
this is fine.
6:54
For bigger games
using a lot of static objects,
6:56
which you also don't
need to worry about yet,
6:59
this could potentially cause issues,
but we'll be alright in our scenario.
7:02
I'll put a link in the teacher's
notes below
7:06
if you'd to know more about this setting.
7:07
Okay, let's click play again,
and now it's almost instantaneous.
7:10
Nice!
7:14
Lastly, notice this little
7:16
asterisk next to our scene
name in our hierarchy?
7:17
This is informing us
that we have unsaved changes in our scene.
7:20
You can go to File, Save,
7:25
or simply use Ctrl S on Windows
or Command S on Mac.
7:27
This is something you'll want to do
frequently, just in case the very rare
7:31
event of Unity crashing happens,
you won't lose tons of progress.
7:34
Alright, in the next video,
we're going to start bringing our game
7:39
to life with physics and collisions.
