Unity might be looking to make some changes to the tools and that their engine gives developers for crafting multiplayer games.
Up until now, developers using the unity engine have used a series of tools and services for multiplayer games referred to as UNet. UNet is separated into two major components. These consist of core networking and enabling services which are used together in order to allow ‘peer to peer (P2P)’ multiplayer games.
In recent years however, the developer feedback for UNet has led to some noted drawbacks with UNet that Unity has shown some concerns with. Most notable of these concerns including developers wishing for “more scalable and transparent core networking and fully supported server authorities’ games that enable the security, stability, and consistent performances required for all levels of success".
From this feedback, Unity has decided that it may be time to move beyond UNet and change their multiplayer technology so that it may better suit the needs and demands of developers.
Unity have already come up with an overview of their initial ‘transition plans’. They will ensure their long-term support to developers who are currently depending on their engine
- The HLAPI and LLAPI will no longer ship with Unity after 2018.4 (LTS): Critical fixes will be provided for two years following the 2018.4 (LTS) ship date, consistent with Unity’s Long-Term Support Policy
- Relay Server and Legacy Matchmaker Services: Continued operation for at least three years following 2018.4 (LTS) ship date, with a clear transition plan provided before this date.
While the UNet features are being deprecated, next generation networking features will be made available soon. These include:
- Game Server Hosting services, which replace the P2P-enabling Relay Server.
- New networking code, which replaces existing UNet HLAPI/LLAPIs. Early versions will be ECS compatible.
- A new Matchmaker service that works seamlessly with Game Server Hosting.
Examples of recently released games that use the Unity Engine include Hollow Knight, Subnautica and the upcoming Bloodstained Ritual of The Night. For more information stay tuned to IGN Southeast Asia.
