Blueprint Communications | Live Training | Unreal Engine

[@apananabeel]

I love how timeless this lesson is. While he uses examples utilizing specific nodes, the underlying principles are the same in Unreal 5.1 and beyond (probably).

This guy and everyone in the background putting this together makes learning unreal fun. i can't stress how rare it is to see a video with this level of education and production on the internet. You guys are the best! This video is a must re-watch, godlike work!

[@tehf00n]

This is the most important video in all of Unreal Engine. I've told people to watch this hundreds of times in the past 6 years. Im writing this comment after telling someone else to watch it. Dont skip it. It sets you up to win.

You can use the pain volume to heal your character by taking the damage and multiply by -1, and the result will increase the character's health.

[@babytime1]

i feel like this works with anydamage right?

[@sam-psonsmith9951]

@@babytime1 this works with any value that you would like to invert. If you have some kind of add/subtract process you can invert it by multiplying by -1

[@LyubomirIko]

36:03 _"The idea of damage lives in the Engine but the idea of health does not"_ its very relevant after wasted my whole day in searching how to do something extremely simple and even didn't find it. I fell damaged indeed.

[@autbo]

Unreal Engine, can you please make more updated c++ tutorials? I would like to learn how to write c++ instead of Blueprints. Not that blueprint is bad, I just kinda prefer the code way of scripting especially after coding in Unity 3D C#.

[@cnash5647]

Super clear explanation, it's a shame that these tutorials have been tucked away in a dark corner, not even a single playlist available.

[@yasararabath2729]

[@ShiroiAkumaSama]

Don't worry just stumbled across this tutorial today.

[@weaponx1969]

Wow, thanks for this video. Until this, I was extremely adverse to developing anything with blueprints because it was new and extremely dissimilar to developing games in C++ like I am used to. I have not made any progress in developing my games since getting a Udemy course that showed me how to do development in C++. This may finally jumpstart me into using blueprints. Could you please make more of these videos about using blueprints or make it a Udemy course?

[@ItsEpicWesley]

This was an absolutely amazing tutorial for someone that understands the concepts of OOP to wrap their head around Blueprints in UE. Outstanding tutorial! Thanks for all your hard work.

[@javiermateos4950]

I started getting into unreal no more than one month ago. The first two weeks I got lost in the "tutorials labyrinth". I had a lot of information but it was disorganized. Only after watching this master class I started getting blueprints communication, specially Interfaces. Thanks Zak! You're a great teacher. It shows that you enjoy sharing knowledge with others. If you ask me, that's a superpower 💪

[@glormond]

Super easy to understand along with those funny remarks on the way :)

[@Aaronmac404]

Been watching Zak Parrish tutorials for as long as I have been a hobbyist. Love this dude. I remember loving his UT2004 mapping and character guides back in the day. Super awesome to see that he is still teaching! He is absolutely stellar at it!

This is the best two hours I have spent while learning Ue4. Zak rules.

[@Lord_Volkner]

Me too. Every other video I've watched has been: "put in this node, plug in that line" with next to no explanation of what the nodes do or why the line is being plugged in. This is, without a doubt, the best UE4 video I've watched so far, and I've watched quite a few.

[@Quein922]

This video is beyond helpful, the amount of stuff I've learned thanks to Zak is immeasurable. Thank you ;)

[@MySteamStation]

Toooonnnnnnnnns of Thanks Mr. Zak.......Thank you Epic Games ......I love this type of tutorials ....(Reminds me of Jason Busby the best teacher ever) \m/

INCROYABLE SES INFORMATION ^^ Certes en anglais mais avec le TTS de Google c nickel

[@llvvds1231]

I don't speak English well, but this video has taught me a lot about BP communication. I started studying 12 hours every day since the pandemic started and the truth of all the videos that I have seen to document myself, this has been the best, I really liked the "bar" that simulates falling at the end of the video . Thank you very much, unreal people, I hope someday to be able to work with you. A hug, and have a nice day. PS: It is translated from my native language to English by google translation, so I don't know, if it will be very well written :(

[@juergent.5972]

Great, after 2 days of reading I finally understand how casting works! Thanks! :)

[@Kinos141]

What I don't get about event dispatch is that they have to still get a ref to the object, so why this over just direct comms? I can't see the point.

[@jorgevalles6835]

More than two hours with gray power point slides, but it is the most dynamic and clear tutorial I have ever seen. 😄

[@thetubeaccount2015]

Thank you SO MUCH. This is EXACTLY WHAT I NEEDED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@NocturnalJin]

If you're new to UE4, know that you should SAVE everything as often as possible. I'm only mentioning this because this video sets a terrible example in that one area. After your first dozen crashes or so, you'll see why CTRL+S is a UE4 dev's best friend. Or maybe it's more of a lover cuz you'll be "hittin' dat" over and over.

[@imagine-games6677]

thought this was only a Mac problem...

[@NocturnalJin]

Hehe. Actually UE4 has been doing a lot better lately. Oh and it's SHIFT+CTRL+S for save all, which is even better.

[@tamasmaar5372]

YOU MUST COMPILE!! Oh god I love when he like goes bananas with this compiling thing, or the blueprint yelling "cannot create in read only" and similar stuff. I think he also was the one in one other tutorial who said "and we're gonna make it a torus 'cause the thought of a flying donut amuses me to no end". :D This is the right style to make a tutorial. Also reminds me of myself at times when I feel a bit funny crazy

[@ChuckWilsonWilsonsStudio]

Wouldnt it be cool if UE4 hired Jason Busby and had both Zak and Buzz make tutorials for the community. Im sure Zak might not be so happy but man the community would sure would love them.

[@Sei783]

Kind of having a bro moment here. Love ya Zak. Actually, I've been learning from you since I first started game design work waaaay back when trueSpace and gameSpace were still a thing. This is a really old video now but if you still read these, do one on all things Array in UE4 blueprints because my wee programmer brain for the life of me cannot grasp arrays in blueprints. Programming with arrays, I love -- blueprint arrays confuse the ever living... out of me.

[@HiphopBurny]

[@fish3010]

Amazing is an understatement. Props for the free information! This is TONS better than any paid course I've had from a 3rd party.

[@nexus1g]

The best way to access a child attribute is to ask them what bills they be paying to slam interfaces closed.

[@AdelaideBen1]

This was really helpful - however I am having all sorts of problems with the receiver object being able to recognize interface functions with an output (even boolean as shown here)... they are only showing up as functions, not events (and yes, I AM COMPILING both the interface and the receiving BP). If i remove the output on the interface signal, then it works fine. I'm on 4.25, and have successfully achieved the interace implementation with calls that have an input, but no output.

[@luistovar6643]

Somebody please put a coat of pure platinum in this video! It was so clear and fun to watch! It should be part of the installation package. I am using 5.4 an it clarifies one of the most confusing and obscure subjects for beginners and intermediate users

[@ThanksIfYourReadIt]

I like that 4th itteration countless patch and still noone can use cast to without an overlap event xD such a dogshit situation. It's like Hey I want to edit the size of a box. Okey reference it then. Uhm.... it's the only box in the scene... I named it bob, can I OVERLAP!!!

Theres a typo at 1:39:36 right? It should be "The Receivers can all get a reference..." and not "The Receivers call all get a reference"?

[@SoaringSimulator]

Is it possible that, if you have one sender and multiple receivers you use event dispatcher. If you have multiple senders and one receivers you need direct casting. Finally if you have multiple senders and multiple receivers you need an event interface.

[@fallenhoenix1255]

Would a blueprint auto-compile feature be beneficial or detrimental to the general workflow of most? Perhaps if it were called along with crtl+s or when certain things like when interfaces are added, would that be useful? Is that already something someone out there implemented in some way?

[@edgardsimon983]

thats the best video on the subject and i still dont get what u have to put in the wildcard pin of a cast node despite developping with the thing show in the video and making thing to work the moment it get out of the scope of classic get controller, get player im lost, do u have to get the class ? how do u get it properly ? what is needed for correctly getting a class thats so annoying it feel like everyon explaining that logic just forgot to understand that u have to use it after u explain it

[@redgeciccone8218]

I have a problem with INT.. I made a topview game, I want the mouse pointer widget image to change when my pointer is over a mob. How can I do that with Int ? do I need to send the ref of the widget and then in my BP retreive this reference to be able to change the pointer ?

(Re. vs. BP components, 1:30:00) Say your AI could draw upon EQS (like in the find a place to hide tutorial) , and now you want your TPC to inherit that sense, but to spot places where things could be hidden….

I can't believe I still can't figure out how to change this variable in my character, depending on whether or not this enemy is clicked, he explains everything so plainly but I can't figure this simple thing out.

[@WhiteNorthStar1]

Zak... a great, great tutorial... excellent, excellent work as usual

[@justind6983]

using interfaces to change anim state seems...idk not right... should I use event dispatchers instead? In my player controller I am grabbing objects by clicking on them and then getting their mesh to get anim instance just to set a function using an interface... This seems like alot of work and probably that I am doing this wrong. There has to be a way to say, " Hey all you guys in this array, if you are able to respond to crouch(for example) do so"

[@hoodwatcher8496]

How would you do the Event Dispatchter thing with another bar f.e. with a mana bar? Would you create another input for "UpdateUI" called "Mana" and do the same thing like with the health or would you create a new event dispatcher for this which only updates the mana bar? In my opinion I would prefer the second method with creating a new event dispatcher because one will call the other event at the same time although you don't need to. Or am I wrong?

[@awoidf]

Man this guy is awesome. He is a D&D GM right?

[@JohnDaniels]

The "Simple Primer" was amazing! Have been studying BP2BP communication for awhile and this summed it all up. Because of all the referencing and everything else you have to setup with interfaces and dispatchers I just use the good old tried and true "Get All Actors" or "Get Actors with tag", these are the work horse nodes and they are so simple and elegant.

[@genlee2354]

Zak. Can you talk about character physical body collision ? So many way to make Physical animation effect in Unreal: "Anim dynamics node" and "Rigidbody node" and "Cloth Effect"
