Hello, I’m currently working on a fighting game using Unreal 5.2 and blueprints.
Before I go to far on development I would like to implement rollback netcode, but I’m unable to find any comprehensive tutorial or documentation on how to make it work in Unreal.
I know how the system should work, but I have no clue on how to start implementing it in Unreal.
Would it be possible to implement it using blueprints?
Thanks in advance.
Hey there @Jonner94! Welcome back to the community! Rollback with blueprint would be a difficult endeavor. If you were to require it, I’d recommend working in C++ and you’d require custom tick and everything you’d do would have to be determinate so nothing with built in physics. A great writeup by Rufus on this thread can get a bit more of an idea from a high level. Depending on your use case, there are also some tutorials that will help you with the general idea.
I know GAS (Gameplay Ability System) implements something similar to rollback but it’s outside of my wheelhouse and I can’t find a proper resource on it.

Then here’s an excellent talk from Netherealm studios on it:
Thank you for the quick response! As mentioned before I have an understanding of how rollback network should work, and I have already came across the other forum post and Netherelam video, but I was looking for something more in-depth, since all post or talks about the topic only discuss just the surface of how rollback works.
Hmmm, how about an implementation in Unreal or one in a custom engine for inspiration?
