Wish I had found this when I started out, it would've saved me so many headaches!

I'd most definitely love a part 2, is the resource on it's own extensive enough?

[MrPstewart]

Best network tutorial for UE I've seen and I've been searching. Well done and thank you!

[snappydue]

Yesss! I need more of this! :) I've been trying to do a simple 1v1 sniper game, and I have a hard time keeping information that are in the PlayerState when the client travel. Since everything is destroyed and recreated when traveling, I don't know how to store that information on the server and then pass it back to the client. (Array of PlayerState? Save on file then reload? Save on the server?)

Anyway, thanks for that video, it was a great revision!

This is the best one to explain how the network frame of UE4 works, amazing video, thank you man!!!

[CENSOR_]

This is a fantastic content, We absolutely need part 2 :D

[II-ergj]

Please make Part 2 for Unreal Networking! Awesome!!!

[fictionalgaming]

30 minutes with it on loop....thats going to be the best way to memorize this topic before actually implementing it.

[da_cat]

Nice explanations ... now i am more confident in making a multiplayer game, i think i can pull it off.

[cnVision]

This makes it seem so much less intimidating.
Thanks a lot, amazing video.

Subscribed! Part 2 please, you're a good teacher

[wiglord]

thanks for this, for me the clarity on replicating variables was what I was missing out on the past few weeks. Now I know the server rules all changes I can fix up some of the issues in my replication events :)

[hahugo]

[Ashborne]

THANK YOU SO MUCH! Been searching the web for hours before I found this video and it helped me a ton! Finally understood what the hell is going on. :D

[avtaras]

Super underrated. Best video I’ve ever seen on replication.

[TechnoVikingOz]

talk more about replication.

specifically, flow of join and leaving games, and traveling between servers. Bonus points for dealing with an end game state (show the game scores for a little while), before traveling to the next map.
