ABE HASKINS: Hey there, Unity developers.
Do you want a game which has detailed user-based analytics,
a game which you can tweak and run experiments on remotely,
a game which is social and sharable from the start?
Well, you've come to the right place.
Let's get started with Firebase and Unity
on this episode of "Firecasts."
[MUSIC PLAYING]
We're going to cover five steps to go from an empty Unity game
to a game that's ready to be shipped on iOS and Android.
First, we'll open up a Unity project.
Second, we'll download the Firebase SDK.
Third, we'll install that Firebase SDK into Unity.
Fourth, we'll configure a new Firebase project
to be used in our Unity game.
And fifth, we'll compile our game for iOS and Android.
Are you ready?
Let's get started.
First, open up the Unity editor.
In our case, we'll be making a new game.
But don't worry if you already have an existing game which
you want to add Firebase to.
The process is going to be exactly the same.
Just open up your existing game instead of making a new one,
like I'm doing.
Once we've opened our project, we'll
see the editor with the inspector scene
view and everything else you'd expect.
Note the empty inspector on the right side.
This is where our Firebase panel will
live once the SDK is installed.
But before Firebase can start adding cool features to Unity,
we need to install Firebase.
Let's hop over to the Firebase docs and download the latest
Firebase SDK for Unity.
At this point, you probably already know
if you want to make an iOS game or an Android game or both.
But the great part about Unity is
that we can make a game that works for both these platforms
with only one code base.
This means that regardless of the mobile platform
you want to build for, you'll download just the one SDK,
the Firebase SDK for Unity.
This download comes as a ZIP.
And when you extract it, you'll see a bunch of files with
a .unity package extension.
Let's take a second to talk about Unity asset packages.
These packages are a standard way in the Unity world
to distribute reusable code.
If you're familiar with other programming tools,
you've probably included an external library
into a project.
Unity asset packages are a lot like this.
It's a way to distribute things for other developers to use.
It's worth understanding that a Unity asset package can contain
lots of different stuff.
It's not just code, like a normal library.
Asset packages can contain images, textures, 3D models,
examples, and yes, code.
Firebase has a lot of features.
And you don't need to use all of them in your game.
Each Firebase feature has its own asset package.
So if you only want to use Firebase Analytics
or you only want to use Firebase Database,
you can include just that package.
Let's go with the simplest feature to implement,
Firebase Analytics.
In the Unity editor, go to Assets,
Import Package, Custom Package.
Then browse to where you extracted the Firebase SDK
and select the FirebaseAnalytics.unity package
file.
Unity will take a moment to extract the package.
Then you'll be prompted to select
which files from the package you want to import.
We can see this asset package taking advantage of the fact
that asset packages can contain non-code assets.
The first thing to show up in this package
are a bunch of icons which are used for the Unity editor
plugin.
We don't need to pick and choose what to import here.
So just click Import and let Unity do its magic.
After another second, you'll be back in the Unity editor.
But it'll have a few key changes.
First, your Assets folder will allow contain some new folders.
And second, your editor now has the Firebase plugin enabled.
Once the spinner in the bottom right has stopped,
you'll be able to start using Firebase.
If you haven't already, it's a good time
to save your Unity scene.
If you're working off a new project,
this won't be done automatically.
So just go to File, Save Scene.
This will save the scene in your project.
And if you don't know what to call it,
just call it something exciting and original, like "Game."
Once we have a saved scene, we can bring out the Firebase pane
in our editor.
In your menu, go to Window and click on Firebase.
Now, depending on your editor setup,
the Firebase pane may show up as a floating window,
or it may show up near the Inspector tab.
Just find it, wherever it is.
The Firebase plugin will help you
get started with any Firebase feature
by linking you to setup guides, code samples, and the API
reference.
You'll notice the very first thing
the plugin shows is advice on connecting
your game to your Firebase project's Android or iOS app.
Like I talked about before, Unity
has the ability to build games for iOS and Android.
Firebase and Unity both work great on these platforms.
But there is some minor work needed
to set up both of these platforms for your Firebase
and Unity project.
Let's start by making a new project on the Firebase console
at firebase.google.com.
Once you've created a project, you'll
be greeted with a screen asking you
if you'd like to make an iOS app, an Android app, or a web
app.
A Firebase project may contain many apps.
This means you'll only need one Firebase project,
even if you're building both an Android and iOS
version of the same game.
I'll be showing you how to build a cross-platform game.
But if you're only interested in iOS or Android,
you can just do that one.
Let's click on the Add Firebase to Your iOS App button.
We'll enter a few basic details.
And then on step two, it'll download a GoogleServices.plist
file.
This is a configuration file that
will tell the Firebase Unity SDK what project to connect to.
Back in Unity, we'll drag this plist file
into the root of our Assets folder.
And the Firebase SDK will automatically detect it
when we build our app for iOS.
This is another situation when you
need to watch that spinner in the bottom right
and make sure it's completed.
If you want to do the same thing on Android,
then click on the Add Firebase to Your Android App button
and enter that same basic information.
And the second step, you'll be given a GoogleServices.json
file.
And just like with the plist, we'll
drag this file into the root of our Assets folder in Unity.
Once you've gotten your configurations in place,
you'll be able to go into your file Build and Run menu
and build your game.
Switching between platforms is as
easy as selecting that Switch Platform buttons in the Build
Settings menu.
Once we have deployed our game, the debug messages
will show us that Firebase Analytics
is enabled and reporting back to your console.
Congrats.
You've gotten your first Firebase library up and running
inside of your Unity game.
But this is really just the start.
There's a lot more Firebase can do inside of Unity,
like saving your users' data to the cloud
with the real-time database, tweaking game play
settings on the fly with Firebase Remote Config, adding
notification support with Firebase Cloud Messaging,
and a whole lot more.
If you want to learn more about what Firebase and Unity can
do together, check out our Unity docs, linked in the description
below, and subscribe to the Firebase YouTube channel.
In the meantime, thanks for watching.
I'm heading back to the arcade.
