The core systems, movement architecture, module integrations, setup wizard, lobby tools, diagnostics, APIs, and demo scenes are functional and actively tested. However, APIs, compatibility, configuration requirements, and behavior may change as development continues.

Game Creator 2 Visual Scripting

Dedicated GC2 Instructions, Conditions, Events, and Properties are included for:

• Starting and joining Fusion sessions
• Creating Shared sessions
• Shutting down sessions
• Spawning and despawning network objects
• Checking authority, ownership, topology, and session state
• Reacting to connection, failure, shutdown, and authority events
• Reading player count, region, RTT, NAT type, and connection type
• Creating, browsing, joining, refreshing, and leaving Photon lobbies
• Fusion Scene Setup Wizard

The guided setup wizard can create, configure, and validate:

• Fusion session bootstrap
• NetworkRunner and scene manager
• Fusion transport and RPC bridges
• GC2 networking managers
• Module synchronization bridges
• Player spawning and spawn points
• Prepared GC2 player prefabs
• Fusion prefab registration
• Character selection
• Chat and session controls
• Photon lobby interface
• Required project and build settings

The wizard detects missing dependencies, conflicting synchronizers, invalid prefabs, missing authority patches, Fusion configuration problems, and incompatible build settings.

Failed validation rolls back the setup instead of leaving the scene partially configured.
