Interested in rollback netcode for your Unreal Engine game?

​​

​

If you think your game project may benefit from rollback netcode, let's have a chat! If it's a good fit, I can expedite the implementation with you and get your prototype up and running quickly. I have developed a plugin that makes this process as easy as possible.

 

Here are some of the specific features I provide to save your team time ⏳ and money 💵:

​

• A lightweight plugin for Unreal Engine focusing strictly on rollback netcode

• Full source code included

• Rewind & replay for both physics and gameplay

• Replication​

  • Client -> Server controller/ KBM inputs

  • Server -> Client broadcasting game state (Rigid body transforms, player inputs, arbitrary variables)

  • Maintaining client and server synchronization over volatile network conditions, with the lowest latency possible

  • Compatible with the existing UE replication​ system

• Storing all relevant game state inside history buffers

• Triggering cosmetic events like VFX or SFX from inside the simulation

• Prediction error smoothing

• Customizable Input delay for latency tradeoffs

• Works with built-in Chaos physics

  • Chaos isn't rollback-friendly by default, but we're able to tweak it to offer a high degree of determinism that works well for most standard features like movement, collisions, and constraints

  • Custom support for other physics engines like Jolt, Havok, Bullet, Box2d, etc is possible. Please reach out!

• Fully decoupled simulation and display rates

  • E.g. Run physics at 30hz but render at a buttery-smooth 144hz​ without jitter

• Cheater-free dedicated server model by default. Peer-2-peer possible as listen server
