Hey guys, in today's video, I'm going to be showing you how to create a door which can be opened and closed by all clients and players in a multiplayer game. This will replicate the door, and it's timeline.

A second part will be released soon to fix a minor bug. If client 1 opens the door, and client 2 goes to close it. The door will snap closed then open again. This is a simple fix, we just need a replicated Boolean so each client knows if the door is already open or not.

yea i was going to ask, what about client to client? so nice you caught that and make a second part fixing it..

The video is very well explained as usual, thanks for putting this content out. Now I hope you don't mind, but I do have some comments on this one: 1) You mentioned the usage of interfaces to avoid casting into heavier objects, but then you ended up casting your array entry into the Door Blueprint anyway, which ended up defeating that benefit of using the interface. 2) The behavior of how a door is open (the usage of the angle and so on) should be encapsulated within the door itself, and not spilled into the character that is interacting with it. Maybe you wanted to showcase the Event Dispatcher, but if the Server/Multicasts RPCs where kept within the Door Blueprint, not only the logic to open the door would be properly encapsulated, but you would also solve issue #1 above, and wouldn't need to cast into the Door Blueprint. Once again, thanks for the content and I wish you the best!

i know this video is 2 years old but when cunnecting the Run on server to the dispatcher it wont let me i get the following Delegate is not compotible with delegate (by ref) Any idea ?

@amigoface 10 ай бұрын

actually it is much simpler : on the bp_door collision box overlap event check if it's a character then call a custom event on the server wich will call a multicast event and in it put the rotation logic . this work just fine in ue5 at least

@eddysouth2023 Жыл бұрын

Hey Matt. Great work. I was just wondering if you still had plans for the second video. I'm not sure where we would use the replicated boolean to make this work correctly.

@goldenclaw_ Жыл бұрын

You can't, that's why he did not make another video. The problem is that the timeline playback position is not in sync between server and client. What you need to do instead is get rid of the event dispatcher (and the cast to) and just make a custom server/multicast RPC to call the interface inside the character BP, then just copy all the code that was called from the event dispatcher and paste it in your interact event inside your door BP.

@bsg8761 Жыл бұрын

Can you use a single event dispatcher to move two different objects from the same bp?

@arankasih1162 2 жыл бұрын

hi matt, this is actually helping me a lot. but my nodes seems a bit off. i need to press interact action twice in order to run the event to open the door. and i can't cast to the door because the object can't be accessed. any ideas? (im in 4.27)

@Fettman89 2 жыл бұрын

Hey when I go to implement function, I get implement event instead, it looks the same as yours after clicking it, so just curious if it's the same thing, re named from an update or something, Or if I forgot a step.

Fixed... I didn't add a space in my event dispatcher scene component, and the spaces are automatically added by Unreal, so I think you have to name them with spaces or it will not connect...
