Client-Side Integration
Integrating Nakama into client-side game applications is straightforward. Nakama provides a comprehensive suite of client-side libraries that enable developers to connect to Nakama servers, send and receive data, and manage user accounts.The most common approach is to use the Nakama Unity plugin for Unity-based games.
This plugin provides a high-level API for interacting with Nakama, making it easy to add social and multiplayer functionality to Unity games.For non-Unity games, Nakama offers client-side libraries for various programming languages, including JavaScript, C#, Java, and Go. These libraries provide a low-level API for direct communication with Nakama servers, giving developers more control over the integration process.
Connecting to Nakama Servers
To connect to a Nakama server, developers must first create a client instance. The client instance is used to send and receive data from the server. The following code example shows how to create a client instance in JavaScript:“`javascriptconst client = new Nakama.Client(“ws://localhost:7350”);“`Once
the client instance is created, developers can connect to the server by calling the `connect()` method. The `connect()` method takes a callback function as an argument, which is called when the connection is established.“`javascriptclient.connect((error) => if (error) console.error(“Error
connecting to Nakama server:”, error); else console.log(“Connected to Nakama server”); );“`
Sending and Receiving Data
Once the client is connected to the server, developers can send and receive data using the `send()` and `receive()` methods. The `send()` method takes a message object as an argument, which contains the data to be sent to the server.
The `receive()` method takes a callback function as an argument, which is called when a message is received from the server.“`javascript// Send a message to the serverclient.send( type: “chat”, data: “Hello, world!”);// Receive a message from the serverclient.receive((message)
=> console.log(“Received message:”, message););“`
Client-Side Libraries
Nakama provides client-side libraries for a variety of programming languages, including:*
- *Unity
- *JavaScript
- *C#
- *Java
- *Go
These libraries provide a consistent API for interacting with Nakama servers, making it easy to develop client-side applications in different programming environments.
Data Modeling and Storage
Nakama offers robust data modeling capabilities, enabling you to define custom entities and components tailored to your game’s specific needs. Entities represent the core objects in your game, while components provide additional properties and functionality to these entities.
Nakama supports a variety of data storage options to accommodate different game requirements.
