O Firebase Realtime Database armazena e sincroniza dados com o banco de dados NoSQL
na nuvem. Os dados são sincronizados em todos os clientes em tempo real e permanecem disponíveis mesmo quando seu app fica off-line.
registrar seu projeto do Unity e configurá-lo para usar o Firebase.
Se o projeto do Unity já usa o Firebase, ele já está registrado e configurado para essa plataforma.
Se você não tiver um projeto do Unity, faça o download de um
app de exemplo.
Adicione o SDK do Firebase para Unity (especificamente FirebaseDatabase.unitypackage) ao
seu projeto do Unity.
Adicionar o Firebase ao projeto do Unity envolve tarefas no
Console do Firebase e no projeto aberto do Unity.
Por exemplo, fazer o download dos arquivos de configuração do Firebase no console e
mover para o projeto do Unity.
Criar um banco de dados
Acesse a seção Realtime Database do
console do Firebase:
Aparecerá uma solicitação para selecionar um projeto atual do Firebase.
Siga o fluxo de trabalho de criação do banco de dados.
Selecione um modo inicial para as Firebase Security Rules:
Modo de teste
Ideal para dar os primeiros passos com as bibliotecas de cliente de dispositivos móveis e Web.
No entanto, esse modo permite que qualquer pessoa leia e modifique os dados. Após o teste, leia
a seção Noções básicas das regras do Firebase Realtime Database.
Selecione o modo de teste para começar a usar o SDK para Android, Apple ou Web.
Modo bloqueado
Nega todas as leituras e gravações de clientes de dispositivos móveis e Web.
Seus servidores de aplicativos autenticados ainda podem acessar seu banco de dados.
Escolha um local para o banco de dados.
Dependendo do local, o URL do novo banco de dados terá um dos seguintes formatos:
DATABASE_NAME.firebaseio.com (para
bancos de dados em us-central1)
DATABASE_NAME.REGION.firebasedatabase.app
(para bancos de dados em todos os outros locais)
O Realtime Database oferece uma linguagem declarativa de regras para que você
defina como os dados devem ser estruturados e
indexados e quando podem ser lidos e gravados.
Monitore o painel Uso e faturamento no console do Firebase para ter uma visão geral do uso do projeto em vários serviços do Firebase.
Também é possível acessar o painel Uso do Realtime Database para ver mais informações detalhadas.

Data is synced across all clients in realtime, and remains available\nwhen your app goes offline.\n\nBefore you begin\n\nBefore you can use\n[Realtime Database](/docs/reference/unity/namespace/firebase/database),\nyou need to:\n\n- Register your Unity project and configure it to use Firebase.\n\n - If your Unity project already uses Firebase, then it's already\n registered and configured for Firebase.\n\n - If you don't have a Unity project, you can download a\n [sample app](//github.com/google/mechahamster).\n\n- Add the [Firebase Unity SDK](/download/unity) (specifically, `FirebaseDatabase.unitypackage`) to\n your Unity project.\n\n| **Find detailed instructions for these initial\n| setup tasks in\n| [Add Firebase to your Unity project](/docs/unity/setup#prerequisites).**\n\nNote that adding Firebase to your Unity project involves tasks both in the\n[Firebase console](//console.firebase.google.com/) and in your open Unity project\n(for example, you download Firebase config files from the console, then move\nthem into your Unity project).\n\nCreate a Database\n\n1. Navigate to the **Realtime Database** section of the\n [Firebase console](https://console.firebase.google.com/project/_/database).\n You'll be prompted to select an existing Firebase project.\n Follow the database creation workflow.\n\n2. Select a starting mode for your Firebase Security Rules:\n\n Test mode\n\n : Good for getting started with the mobile and web client libraries,\n but allows anyone to read and overwrite your data. After testing, **make\n sure to review the [Understand Firebase Realtime Database Rules](/docs/database/security)\n section.**\n\n :\n | **Note:** If you create a database in Test mode and make no changes to the default world-readable and world-writeable Rules within a trial period, you will be alerted by email, then your database rules will deny all requests. Note the expiration date during the Firebase console setup flow.\n\n : To get started with the web, Apple, or Android SDK, select testmode.\n\n Locked mode\n\n : Denies all reads and writes from mobile and web clients.\n Your authenticated application servers can still access your database.\n\n3. Choose a location for the database.\n\n Depending on the\n [location of the database](/docs/projects/locations#rtdb-locations), the\n URL for the new database will be in one of the following forms:\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.firebaseio.com` (for\n databases in `us-central1`)\n\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e`.firebasedatabase.app`\n (for databases in all other locations)\n\n4. Click **Done**.\n\nWhen you enable Realtime Database, it also enables the API in the\n[Cloud API Manager](https://console.cloud.google.com/projectselector/apis/api/firebasedatabase.googleapis.com/overview).\n\nSetting up public access\n\nThe Realtime Database provides a declarative rules language that allows you to\ndefine how your data should be structured, how it should be indexed, and when\nyour data can be read from and written to.\n| **Note:** By default, read and write access to your database is restricted so only authenticated users can read or write data. To get started without setting up [Authentication](/docs/auth), you can [configure your rules for public access](/docs/rules/basics#default_rules_locked_mode). This does make your database open to anyone, even people not using your app, so be sure to restrict your database again when you set up authentication.\n\nNext Steps\n\n- Learn how to [structure data](/docs/database/unity/structure-data) for Realtime Database.\n\n- [Scale your data across multiple database\n instances.](/docs/database/usage/sharding)\n\n- [Save data.](/docs/database/unity/save-data)\n\n- [Retrieve data.](/docs/database/unity/retrieve-data)\n\n- [View your database in the\n Firebase console.](//console.firebase.google.com/project/_/database/data)\n\n- Prepare to launch your app:\n\n\n - Set up [budget\n alerts](/docs/projects/billing/avoid-surprise-bills#set-up-budget-alert-emails) for your project in the Google Cloud console.\n - Monitor the [*Usage and billing*\n dashboard](//console.firebase.google.com/project/_/usage) in the Firebase console to get an overall picture of your project's usage across multiple Firebase services. You can also visit the [Realtime Database *Usage*\n dashboard](//console.firebase.google.com/project/_/database/usage) for more detailed usage information.\n - Review the [Firebase launch checklist](/support/guides/launch-checklist)."]]
