CCG Kit

Foundations of Multiplayer Card Game Architecture

CCG Kit is a development solution designed for creators building multiplayer collectible card games within the Unity engine. It serves as a comprehensive starting point for projects ranging from independent prototypes to commercial-scale titles. The kit is structured to handle the complex networking requirements inherent to the genre, specifically focusing on server-authoritative multiplayer functionality. This architecture, which leverages the Mirror networking library, ensures that the game logic is processed on the server to maintain state integrity and prevent common client-side exploits.

For developers looking to move beyond local testing, the kit includes an official integration with the Dedicated Server Kit. This allows for the transition to dedicated server setups without requiring additional external systems. The package is fully compatible with Unity 6, ensuring that projects can utilize the latest engine features while maintaining the kit’s core networking and logic structures.

The Visual Card and Deck Editor

One of the central components of the kit is its integrated editor, which provides a visual interface for defining the fundamental properties of a game. Rather than forcing developers to manage card data through raw code or external spreadsheets, this tool allows for the creation of new cards and decks directly within the Unity environment. This visual approach streamlines the process of balancing card stats, defining deck archetypes, and managing the various assets associated with specific game pieces.

While the editor facilitates the definition of card properties, the kit is designed with the expectation that developers will interact with the underlying C# source code. The code is extensively documented, providing a blueprint for how a complex TCG (Trading Card Game) can be architected. This makes the kit useful not only as a production tool but also as an educational resource for understanding the implementation of card game logic in a multiplayer context.

Single-Player Functionality and Prototyping

Beyond its multiplayer capabilities, the kit includes a single-player mode that allows developers to test their mechanics against an automated bot. This feature is particularly useful during the early stages of development for verifying card interactions and game balance without the need for a second human player. The bot implementation also serves as a foundational structure for those interested in building story-driven campaigns or dedicated single-player modes.

To demonstrate these features in a practical setting, the kit provides a complete demo game. This demo reflects the mechanics of classic card game titles, showcasing how the various systems—such as the user interface, card handling, and turn logic—interact in a live environment. The UI in this demo utilizes Unity’s built-in UI system, providing a familiar framework for developers to modify or replace the interface to suit their specific art style.

Production Workflow and Technical Requirements

Integrating the CCG Kit into a production workflow requires a clear understanding of its technical scope. The developer emphasizes that this is not a visual scripting solution or a “one-click” game generator. A working knowledge of C# is necessary to extend the asset. While the visual editor covers many game concepts, custom card effects that go beyond the included demo will require the developer to write additional code on top of the existing codebase.

The kit provides a complete set of unique graphics designed by ricimi, which can be used to populate the demo or as placeholders during the development of custom art assets. This allows teams to focus on core mechanics and code architecture before finalizing the visual identity of their game.

Scope of Included Systems

When planning a project with the CCG Kit, it is important to distinguish between the gameplay systems provided and the external services required for a full commercial release. The kit focuses on the gameplay loop, networking, and card management. It does not include server-side persistent storage features. This means that systems such as card shops, pack opening sequences, player inventories, and tournament structures must be developed independently or integrated from other sources.

The kit is intended to serve as the functional engine for the match itself. By providing the server-authoritative logic and the tools to define card behavior, it addresses the most technically demanding aspects of CCG development, allowing creators to focus on the unique mechanics and progression systems that define their specific game.
