(Abandoned project, use com.unity.netcode instead

Open Netcode is a feature rich networking package for Unity DOTS.

State: Early Preview. I'm waiting for Unity DOTS 0.50 to release so I can get the package to an alpha stage. Don't use this for anything yet. MIT license will be added when it's ready.

Main Features

• Clientside Prediction & Server Reconciliation
• Public and Private Snapshots
• Events
• Delta Compression
• Spatial Hashing
• Bit Compression
• Code Generation
• Tick Synchronization and Tick Dilation

Requirements

• Unity 2020.3.24f1 (Probably works with later versions in the same tech branch)
• Use of the custom DOTS packages included in the project. Once Entities 0.50 is released they will no longer be necessary.
• Understanding what Unity DOTS is and how to write DOTS code.

TODO

• Lag Compensation
• Clientside replay system.
• A generic way to predict multiple components. It's only predicting EntityPosition at the moment.
• Custom logging.
• Implement RCON protocol.
• Unit tests. Look into making an integration test for the whole pipeline.
• Use the ProfilerRecorder API to display stats in the profiler.
• Snapshot Prediction as described in the Unity FPSSample Deep Dive video.
• LZM compression of snapshots.
• Wrapper around the Unity Physics Package to use it for physics simulation.
• Hybrid read-only way for "attaching" gameobjects to networked entities.
• Unity Relay Service
