SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Setting up Unity multiplayer with Netcode for GameObjects involves many error-prone manual steps: creating the NetworkManager, configuring transports, registering network prefabs, attaching NetworkObject components, and driving host/server/client sessions. This Skill automates those operations with source-verified skills for NGO 2.x, returning structured errors when the package is missing or a feature requires NGO 2.5.0+. ## Core Features & Use Cases - Manager & Transport Setup: Create and configure NetworkManager, UnityTransport addresses, Relay server data, and debug latency simulation. - NetworkObject & Prefab Management: Attach NetworkObject/NetworkTransform/NetworkRigidbody/NetworkAnimator components, build NetworkPrefabsList assets, and set the player prefab. - Runtime Session Control: Start host, server, or client in PlayMode, query connection status, spawn manager state, and shut down sessions. - NGO 2.5+ Features: AttachableBehaviour, AttachableNode, and ComponentController support with version gating via netcode_version. - Use Case: You are prototyping a co-op game and need a NetworkManager on port 7777, a registered player prefab, and a generated NetworkBehaviour script with RPC and NetworkVariable templates before entering PlayMode to start a host. ## Quick Start Ask the AI to check the Netcode setup, create a NetworkManager with UnityTransport, register your player prefab in a NetworkPrefabsList, and start a host session in PlayMode.

Frequently Asked Questions about unity-netcode

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Netcode for GameObjects multiplayer in Unity?▼

Create a NetworkManager with UnityTransport, configure NetworkConfig fields like TickRate and topology, set the transport address and port, then register prefabs in a NetworkPrefabsList. This Skill automates each step with netcode_create_manager, netcode_configure_manager, and netcode_add_to_prefabs_list.

How do I spawn a network object with Netcode for GameObjects?▼

Spawning is not exposed as a skill because it requires a running NetworkManager. Call .Spawn() or NetworkManager.SpawnManager.InstantiateAndSpawn from NetworkBehaviour runtime code with server authority; the skills only handle prefab registration and manager lifecycle.

Does this support Netcode for GameObjects 2.5 AttachableBehaviour features?▼

Yes, AttachableBehaviour, AttachableNode, and ComponentController skills are included but require NGO 2.5.0 or newer. Call netcode_version first; on older 2.x installs these skills return a structured requires-2.5.0+ error instead of failing.

Why does netcode_start_host fail in Unity Edit Mode?▼

Runtime control skills (start_host, start_server, start_client, shutdown) require PlayMode because they operate on a live NetworkManager. Enter PlayMode first with editor_play, then invoke the runtime control skills.

What happens if the Netcode for GameObjects package is not installed?▼

Every skill returns a NoNetcode() error with install instructions when com.unity.netcode.gameobjects is missing. Install the 2.x package via Unity Package Manager before calling any netcode skill.
