com.unity.netcode 1.5.1
Source docsNotes: processedReleased May 8, 2025
Unity Compatibility
Minimum Unity: 2022.3 (20f1)
Package Dependencies
- com.unity.entities (1.3.5)
- com.unity.modules.animation (1.0.0)
- com.unity.transport (2.4.0)
✨ Features
- Experimental host migration feature added, enabled with the ENABLE\_HOST\_MIGRATION define but otherwise hidden.
- With ENABLE\_HOST\_MIGRATION defined, when a client reconnects to a server after disconnecting the connection entity on both sides will receive a `NetworkStreamIsReconnected` component. An internal unique ID is added to connections to track this behaviour.
📈 Improvements
- IsReconnected split into NetworkStreamIsReconnected for reconnected connections and IsMigrated for re-spawned ghosts (Host Migration).
🔧 Bug Fixes
- An issue with Mutiplayer PlayModeTool window, throwing exceptions when docked after a domain reload. The issue was due to because of an access to `EditorPrefs` and `Application.productName` while restoring the window state.
- Issue where, during host migration, ghosts could be migrated with a 0 id and type. Causing various issues when instantiated on the new host.
- Crash which could happen after host migrations when the server is deploying the host migration data.
- Issue with prespawn prefab entity list initialization after a host migration, the ordering of the prespawn ghosts could be shifted by one because of the internal `PrespawnSceneList` entity prefab creation. This would result in *invalid ghost type X (expected X+1)* off by one style errors.
