How can i make my game actually playable in multiplayer?

I mean, right now hud gets duplicated one of top of other when i put more than 1 player and i suppose that i need to do something to make my building system useful for multiplayer…
Im following this tutorials for the hud and building system: [Eng] Let's Create Fortnite's Building System: Player States #06 - YouTube
how can i make that things useful for online gaming?
also, if anyone has discord or something and can teach me or help me i will appreciate it a lot cause im a noob on making client and server things

I can show you guys anything you want, just ask and i can show blueprints if you guys need to see anything to help me :’) thanks for reading, hope someone can actually help me ^^

im using the tutorial just for the building system but at the same team i learn about the hud, i will change it visually so i actually want to have it on server and client i suppose too

I didn’t see a problem in the GIF you linked to. What’s wrong exactly? You say the HUD is duplicating on top of each other but I can’t see it happen in the GIF.

I’m going to guess you mean that for the server it is making too HUDs on the same screen for every player, not just the player the HUD belongs to, and the client is not creating any HUDs. Is that correct?

I actually fixed the hud by myself, now i just need someone to teach ot tell me.how to make multiplayer building systems ^^ but thanks!

atleast you tried, i fixed the hud thing, i will make your comment as an “fixed” ^^ thanks! if someone can actually tell me how to do the building system just comment or ask me for my discord :smiley:
