I have just finished setting up the attack and combos for my character. However, after going into the client double player mode, none of my roll/attack animations play. I can’t even jump. How can I solve this? Is it possible to convert my blueprint scripting into multiplayer seamlessly? Thank you.
Unfortunately it’s not seamless because you have to tell the game little thing that happens in multiplayer and it’s a long involved process. They do this to make the netcode more efficient, it only sends data that you tell it to send and there’s no simple way of putting it into your game.
You will have to do research on “ue4 replication” and how to implement it. Here is a live stream where they show some of the basics :
Good luck on your game

Thank you for the link.
