Agent8 Server SDK

We aim not only to create single-player games through Agent8 but also to enable the creation of various multiplayer games. Therefore, Agent8 provides a game server along with an extremely user-friendly SDK, allowing AI to easily utilize the game server during game development. The server usage examples below are elements that AI handles directly; however, if users desire more advanced tasks, they can learn from the content below and directly leverage the Agent8 game server.

Integrating Game Server

Agent8 provides a fully managed game server that can be easily used in client code. It also offers a package(@agent8/gameserver) that can be used immediately on the client side. By utilizing this, you can persistently store user states or implement real-time multiplayer games.

Check out the architecture diagram below to see how these systems interact:

Global vs Room

Agent8 provides two distinct state management systems tailored for different gameplay needs:

Global State

• Persistently stores data across sessions (character profiles, inventory, achievements)
• Optimized for long-term persistence with periodic synchronization
• Accessible from anywhere in the game
• Recommended for:
  • Player profiles and progression systems
  • Game-wide leaderboards
  • Persistent game economies

Room State

• Ephemeral session-based containers for real-time gameplay
• Supports instant synchronization between room participants
• Limited concurrent players per room
• Recommended for:
  • Battle royale matches
  • Cooperative dungeon runs
  • Real-time strategy games
