Unleashing High-Performance Multiplayer Games in Unity

For programmers venturing into the exciting world of multiplayer game development within the Unity engine, choosing the right framework is crucial. Enter, a feature-rich solution designed specifically to empower creators with the tools they need to craft exceptional online experiences.

A Programmer-Centric Approach

Unlike many frameworks that prioritise visual editing tools, often at the expense of performance, Zapnet takes a different stance. It caters to programmers with a strong understanding of coding principles, offering a streamlined and efficient foundation. This approach eliminates unnecessary overhead, allowing developers to tap into the full potential of the Unity engine and create high-performance games.

Community and Support

The Zapnet team recognizes the importance of a supportive community for game developers. They’ve established a dedicated channel on Discord, fostering a space for discussions, troubleshooting, and knowledge sharing. Here, programmers can connect with fellow Zapnet users, seek help when needed, and contribute to the overall growth of the framework.

Extensive Documentation: Your Development Companion

Comprehensive documentation is a developer’s best friend, and Zapnet delivers in this aspect.  A well-structured getting started guide eases you into using the framework, while the in-depth API scripting reference provides a detailed look at all the available methods and classes. Every element is meticulously documented, ensuring clarity throughout the development process.

Concepts and Features for Seamless Multiplayer Development

Zapnet boasts a robust feature set that caters to the creation of various multiplayer game genres. Whether you’re crafting a turn-based strategy game, a fast-paced shooter, or an expansive open world adventure, Zapnet provides the tools you need to deliver a smooth and engaging online experience.

Network Prefabs: Effortless Prefab Instantiation

Instantiating prefabs across the network is a breeze with Zapnet’s NetworkPrefab component. Simply assign this component to your prefabs, and with a unique 2-byte identifier and a single method call, you can spawn them on other players’ screens effortlessly.

Delivery Modes: Flexible Data Transmission

Lidgren networking library forms the foundation for Zapnet’s networking functionality. By leveraging Lidgren’s versatile delivery modes, you can tailor data transmission based on your game’s specific needs. Reliable, Unreliable Sequenced, Reliable Unordered – these are just a few of the options available, ensuring you have the flexibility to optimize network communication for different data types.

Entities: The Backbone of Networked Objects

In the realm of Zapnet, entities are the cornerstone of network replication. Any object you intend to synchronize across the network inherits from the entity class. By default, the position and rotation of these entities are automatically kept in sync and smoothly interpolated, creating a seamless experience for players.

State Management Made Easy with States

Efficient network communication is key to maintaining a smooth gameplay experience. Zapnet’s state system simplifies this process. Each entity can have its own state class, inheriting from a basic state class provided by the framework. This class holds frequently updated variables that need to be transmitted across the network. The straightforward approach ensures these updates are handled efficiently, minimizing unnecessary data transfer.

Event System: Enabling Dynamic Communication

The event system empowers you to create custom event data types that can be serialized and transmitted across the network. These events can be broadcasted globally or targeted towards specific entities within the game world. This flexibility allows for versatile communication between players and game objects, fostering a dynamic and interactive environment.

Synchronised Variables: Streamlined Updates

While states handle frequently changing variables, entities can also have synchronized variables. These variables differ in that they only update on the network when their values change. This approach optimizes data transmission by avoiding unnecessary updates for static or slowly changing variables.

Remote Calls: An Alternative Communication Method

Events are generally the preferred method for communication due to their performance benefits. However, Zapnet also offers remote calls, its version of Remote Procedure Calls (RPCs). Unlike some frameworks that rely on reflection for RPCs, Zapnet’s implementation avoids this overhead, resulting in a more performant solution.

Network Hitboxes: Ensuring Precise Collision Detection

Accurate collision detection is crucial for maintaining fair and responsive gameplay in multiplayer games. Zapnet’s built-in network hitbox rewinding system addresses this need. By attaching the NetworkHitbox component to your entities, you can leverage automatic hitbox rewinding. This ensures that collision detection is based on the position of objects at the appropriate server tick, guaranteeing a smooth and fair experience for all players.

Controllables: Simplified Player Input Management (continued)

Zapnet streamlines player input management through the concept of controllables. This approach involves inheriting the base controllable entity class for your player object. This class handles the following tasks:

Transmitting Input Data:

When a player presses a button or moves their joystick, the controllable entity automatically transmits this input data across the network.

Client-Side Prediction:

To maintain a responsive gameplay experience, Zapnet utilises client-side prediction. This means the game anticipates the server’s response to the player’s input and updates the player’s position and actions locally on the client’s machine. This creates a smoother experience for the player while the server confirms the validity of the input.

Server Reconciliation:

Once the server receives the player’s input data, it performs its own calculations and checks for any discrepancies between the client-side prediction and the actual server state. Any inconsistencies are reconciled, ensuring a fair and consistent game world for all players.

By leveraging controllables, you can significantly reduce the boilerplate code required for handling player input in your multiplayer game. This allows you to focus on the core gameplay logic and create a more engaging experience for your players.

Zapnet: A Communication Powerhouse with Trade-offs

Zapnet has emerged as a powerful communication tool, boasting a range of advantages that have revolutionized how people connect and share information. However, alongside its benefits lie certain drawbacks that users should consider.
