Blueprint communication in general i feel is one of the more difficult aspects of learning unreal engine. I have learned casting, i have learned blueprint interfaces and now starting to get a grasp on event dispatchers. Thank you!
Excellent description! Short, just about the right balance between simple and complex to get a grasp of what I don't know and what I ought to and why! Have a good day!
Hi! I'm a level design student and have been having a really hard time with scripting. Your channel and videos have been so helpful for me to learn and make fun things for my levels! Your content is amazing, thank you 😊
Oh, this is very helpful. I just found it and I'm sure to use it in my 10 level game where the player comes back to a slightly different level 1 after beating each level. I was dreading making a huge blueprint and now I know I wont need to.
Bro, I've a little bit of confusion. Usually, if we cast to third person bp From level bp, we can communicate with that. Like we're increasing our level in the character bp and then we're casting it from our level bp. So we can directly call the code that you called from the custom event. Isn't it? Ex (From level bp) : Event Beginplay -> Cast to Third Person Character -> Branch (Condition: Level == 5) -> Play Sound -> Destroy Actor. So why should I use Event Dispatcher? Idk if I explained if perfectly, but hope you'll understand what I'm talking about!
Because with the example you just gave, the level bp would only be checking if the player is level five at BeginPlay, which will always return false unless the player starts out at level 5. The reason an event dispatcher is used is because the player's level needs to be checked every time there is a level up, not just at BeginPlay.
Matt, what if we want to do the opposite, have the Event Dispatcher called in level BP, but bound in Third Person Character BP? I can't seem to figure how to get that reference, can't cast to level BP, in another vid you made you said you could use get actor of class, but didn't see the event dispatcher. Any help is appreciated, thanks!
Hey, I'm having trouble for some reason binding a use item event in an inventory system to a custom play montage event. Should I be in them item itself? Then to player? Or should I be in the widget?
Do you have a video on how to make a stealth where when the enemy see you first a eye icon pops up above them telling the player if there about to be caught or detected kinda like dishorned or the last of us etc
Will this work for let say to fire off a animation like if I have a axe or gun blueprint and have them in my action bar or inventory can use to spawn in hand?
You could use it for that yeah, as long as you call the dispatcher when you want to play the animation, and it fires off an event which then does play the animation. It should work :)
I'm wondering. Does the level blueprint need steps to replicate, like in your character blueprint you need to create an event and make it run on server and another one to multicast right. But if an event runs in the level. It should automatically run on all clients who are connected and in the level right?
I don't believe it is replicated by default, I.e. you still need to create the custom events to run on server and clients etc, however you can run these events in there. So normally they need to be in a character controlled blueprint, I.e. a door BP wouldn't be able to run replicated events, but this does work in the level blueprint. But, you may be correct, it does run on all clients, but I don't believe it is correctly 'synced' (I think that's the right word), for replication. I'll have to look into that more, you've raised a good point and got me interested haha. I've never really tried to run a replicated event from the level blueprint before to be able to tell.
I've been working on making games Unreal for so long (since 2016), and It really doesn't make sense that after all this time, I just learned what the event dispatcher does.
my notes: 1) Create event dispatcher in first blueprint (CALL EVENT DISPATCHER) 2) In second blueprint Cast/Get the first blueprint to get a reference to it 3) In second blueprint, BIND EVENT DISPATCHER to a custom event to use the event dispatcher
I know this an year old video, but TH-cam just recommended it to me now. My question is, it's easy to cast for the Player character, using Get Player Character as the wildcard object. But, what about when it's not a Player character? How would you use E Dispatchers when not set up in the Player character? We can't just cast to something, and have a wild card object available to plug in for the cast to succeed, right?

I really appreciate the unpolluted focus on Event Dispatcher, without complicating the entire thing. It really helped. Thank you
Keep doing this series it's so helpful
Thank you so much for the support :)

Just started learning unreal and this will be my go to documentation from now on. Thank you!!!!
This is brillantly explained, one of the annoyances I had in Unity is easily solved here. Thx!

Teach a man to fish and you feed him for a lifetime.
Thanks as always :)
Awesome! I was just learning these last night! Perfect
straight to the point , very good.
Just want to say thanks
Thanks for your support Phoenix :)
Thank you Matt, wonderful. This sounds very useful.
Awesome explanation, this helped me a lot. Thanks!
Can you do a video about how to make a perches shop in your game with blueprint . Love your videos 🤩❤️
Can you cover bp interface please
Would you help me? I would like to cast to Actor (in order to create box collision sun animation) how should I connect it?
And all that great stuff...

I have a problem where i cant place 2 events without it leading me to an already exstiting one. like I want 2 events not 1
Do you have a video on how to make a stealth where when the enemy see you first a eye icon pops up above them telling the player if there about to be caught or detected kinda like dishorned or the last of us etc

perfect

I will definitely test this out later today.

Seems like a job for Interfaces then
