[UE4] Creating a multiplayer ready DOOR system in Unreal Engine!

[@НикитаГришин-ш7ь]

Good lesson, but... Why not use interfaces for interactive objects? Don't you think that your approach is very ossified. A huge tree of loosely connected objects, like a pickup truck and a lever. Interfaces provide the same functionality and more flexibility.

Can I have overlap event based multiplayer replication stuff for same door like tutorial

[@allashama]

i'm using way too much RPC Run on Server and Run on Client to get my things. I have a question, does it change something on performance to call RPC? too much informations to know. sorry is the question seems dumb.

[@ISDISNJH]

bit of question have a mesh as as door with force field, when I go to use door has host it sets force field as invisible on host for opening closing but if I try to set visible from client on mesh that it only sets force field as visible on client and invisible but host is only seeing the visible not the client making force field invisible again.. any suggestions on what could be causing this issue?

[@torquesoftware]

Your client can't set visible objects for everyone on the server. Clients can only control actors they own. If you want to toggle visibility of something, have to do it from the server. (You could get messy with RPCs, but I wouldnt)

[@irjayjay]

Loving your tutorials, been trying to find one where someone shows me how to properly animate a static mesh and this is it! One question though, would it not be better to only do the line trace when the player presses the interact key, rather than doing a line trace all the time and setting the current interactable? I heard line traces were expensive, or is it negligible on the client?

[@aaronhunt7204]

It's a lot better to trace one time, technically speaking. The reason I started using Event Tick for this is because sometimes I like to use outline materials for intractable blueprints, and it's a lot easier to "un-outline" something when it's reference is invalidated on tick. That's an example of a real use case, I guess, but for this tutorial it was just nice to see the red line in real time.

@@aaronhunt7204 ah I see, makes total sense in that scenario! Awesome, thanx for making great, trustworthy content! There are so many bad tutorials out there, I feel like your stuff is just a treasure in a junkyard of other videos.

[@irjayjay]

@@aaronhunt7204 one more thing! Would love to see some videos of whatever project you're actually working on! If it's something you're ready to share?

[@aaronhunt7204]

@@irjayjay I can definitely show some more content! I've been hustling on a 3-year project called Civil, which is actually where I use a lot of the systems in my tutorials. You can check it out here! playcivil.com

"So this is the project walkthrough [...]" What you did there, I see it.

[@aaronhunt7204]

Haha, I was going to make a "tu _door_ ial" joke, but I thought it would be too much.
