The Most Common Mistake Beginners Make in Unreal Engine | UE5

- The Observer Pattern:
Software Design Patterns are like a manual on how to write good code, whether you're using Blueprints or C++, knowing good software practices is a MUST!
I hope this first video in the series gives you a good intro on what design patterns are and how the observer design pattern can be used.
This will be done through the use of "Event Dispatchers". Event dispatchers in unreal engine use delegates, which are an implementation of the pub/sub (observer) pattern.
Through blueprints, event dispatchers are available, but have certain limitations that will be touched upon in this series

About me:
I've been learning game development for a few years now, I have a background in software engineering, and I also have a background in education, so being able to combine my love of gaming, software engineering and education is the best way to spend my time.
I am currently working on a few unreal engine games as a hobby, but I am also trying to build a community, thus I am creating RUclips tutorials to find others who are interested in game development and design.

This is the kind of tutorials youtube needs more of! You actually explain conecepts, instead of just telling your viewers to copy paste some code with no explanation. I don't leave comments often, but you definitely deserve it.
Thank you so much for your kind words! I really appreciate your support and I'm glad you find my tutorials helpful and informative. Your feedback means a lot to me.
I literally came down here to write the same sentiment. Thank you!
Here to say the same, this is a really great video and i'm excited to see more in the series. Started watching this channel to start learning some basic AI stuff, but this kind of content I will absolutely love to see.
It's almost uncanny how you described my exact method for this at the beginning. Thanks a lot for not just teaching solutions to problems, but teaching more efficient workflows and good practices while you're doing so. It might be more work up front but it absolutely pays off!
What's uncanny is his eyes bro is seeing into my future
Thank you @@perochialjoe I'm really happy that you see the value in what I do. I truly try to teach how to become a proper developer instead of just how to copy and paste code. Glad that you find it helpful. Thanks for watching and commenting ☺️🙏
Hahah thanks @maxten1463 ☺️
You are an ABSOLUTE SAINT for actually explaining where concepts can be used for actual functionality in the engine instead of just showing people how to make a shiny looking functionality. God bless you man.
Thank you! I appreciate your kind words and I'm glad you find my explanations helpful.
I dont leave comments often, but just wanted to say that your tutorials are easy to follow, and I enjoy watching them! Youre doing a great job!
Hey Eden, thanks so much for watching and commenting. I'm really glad you found this useful 🙏
THIS is EXACTLY what youtube tutorials should be like! Very helpful, easy to understand, you explain the why and hows. Perfect, thank you
Thank you for your kind words! I'm thrilled to hear that you found the tutorial helpful and easy to understand. Your feedback means a lot to me! 😊
This is the kind of UE tutorial video I've been searching for for years! It's so much easier to understand concepts and retain that kind of information when it's described and showcased in this way. Excellent work!
Thank you for your kind words! I'm thrilled to hear that you found the tutorial helpful and easy to understand. I aim to make complex concepts more accessible and it's rewarding to know that it's making a difference for you! Keep watching for more helpful content in the future.
Something you could add to avoid hard references to actors (like you have currently) is handling dispatchers in actor components.
In that way you can have a reference to a generic character instead, get component by class, bind to onDeath that is ran in the component.
Hard references should be avoided when possible because otherwise you will always have the entire enemy class and all its dependencies in memory whenever the Widget is in memory.
Maybe its too much for one lesson, but i think it would be better to not teach hard references.
I think these types of videos are badly needed and i hope you will make many more in the future. Excellent presentation and easy to follow.
I like how you think! You're indeed one step ahead of the rest ;) My plan is to cover actor components when I talk about the component design pattern, and show how it relates to the observer pattern as well. The result would be very similar to what you described, and one of the benefits is indeed runtime "soft" references that can be garbage collected easily
wow I need a tutorial about this. Soft references + using dispatchers inside components
@@AliElZoheiry if you're going for "soft" references, I would advise using interfaces instead. this way you could simply add an IKillable interface, that describes an event you can bind to. you can implement multiple interfaces, so at runtime you could check if the IKillable could be cast to another interface that knows whether or not it's an enemy.
Hey@@jackie.p6891 Thanks for the suggestion, a lot of people seem to be confused about this. I would definitely add event dispatchers in an interface if possible, but in blueprints, that's just not possible. To bind to an event of a class, you need a reference to that exact class, an interface reference isn't enough because you CAN'T add event dispatcher definitions in an interface.
In the next lesson though, as I mentioned, I will be going over the mediator pattern to create an event manager which will remove references all together, both hard or soft
@@AliElZoheiry Oh, my bad. I've been a programmer for years, but am pretty new to Unreal. Seems weird to me that you can't add event dispatchers in an interface. anyway, nice video, I'll definitely check out the next one!
i learned some UE at school, more specifically blueprinting and i have been refreshing it a little and stumbled across your videos, i am flabbergasted, the way you explain things is so clear and simple! amazing work man! you're A-grade teacher material!
Thank you so much for your kind words! I'm really glad to hear that my explanations are helping you understand UE better. It's feedback like this that makes creating these videos so rewarding. Keep practicing and exploring, and I'm sure you'll keep mastering your skills!
In Unreal 5.2 and up, You can also just call interface functions on the overlapping or hitting actor.
The enemy calls the player when hit and dead, the player calls the interface function for the door, when no more actors of class exist each time an enemy dead event is called. There are many ways of creating in Unreal with the new interface functionality.
I’d say use interfaces to generate blueprints fast, and when working you can refactor to use proper patterns
Interfaces are not new to 5.2. Epic has been recommending using Blueprint Interfaces for years and years because the hard reference created by a Blueprint cast can be extremely costly memory wise.
Unfortunately blueprint interfaces don't support having event dispatchers in there. So you would always need the exact reference to the class to bind to an event from it. And even if interfaces supported event dispatchers, you would still need a reference to some class that implements this interface to bind to it
@@AliElZoheiry Technically, you just need a reference to the actors that implement the interface, not their class (and you can use 'Get All Actors With Interface' to get the actors at run time). I believe it's also possible to define delegates in a native UInterface class, and set them up so they can be bound in Blueprint, but I haven't tried it.
@@Fafhrd42 cool! Sounds awesome, that get all actors with interface must be costly too though :(
Like I stated in my initial comment: use interfaces for prototyping fast, then when that works think about refactoring and changing it to use design patterns.
@@AliElZoheiry correct, I personally use the hit or overlap events for the interactive part. (The collision system part that is)
So I have both the overlapping and overlapped (and hitting) objects available in those events. So it’s no biggie.
If you will use another way of hitting actors (like Multi trace sphere let’s say) you’ll also have the reference to them, so it works out with interfaces just fine too!
It’s all about advantages and disadvantages of each method 😁 cheers fellow Game devs
My mind is blown how clean and easy someone is explaining that! You are a gem in all these Unreal tutorial channels. This is a real learning lesson and not just ''look at me how I did that and try to copy''. This is awesome.
Thank you so much for your incredibly kind words! I'm happy to hear that you find my tutorials helpful and valuable. Your support means a lot to me! Keep learning and creating amazing things in Unreal Engine!
I've watched a few of your videos, and many others of others. And I have to say I am really looking forward to this series. The way you explain your code and the design patterns within it are some of the best ive seen on youtube.
Thank you Michael, real glad you found it useful 🙏☺️
A great tutorial!!, but there is a little adjustment that I would add to make it much better:
instead of dispatching an event from the enemy,
1- I would create my own GameInstance class, and this can be referenced from anywhere.
2- Now in my GameInstance class, I would add the event dispatcher that you added in the enemy
3- in the enemy, call the GameInstance event that you added
4- in the widget, just reference the GameInstance, and bind to the event
the benefit: you won't need to iterate all enemies to bind so many events (consider the worst case scenario of having thousands of enemies where you will have thousands of binds).
Regards!!
The game instance should only contain stuff that is necessary to "survive" level switches. Using interfaces is the best way.
But in the end it doesnt really matter, as long as you are happy with it. :D
Hey 3dsakr, what you're describing is an attempt at creating the observer pattern with an event bus, which unfortunately doesn't have native support in blueprints. I will be going over a custom implementation you can use to create an event bus and prevent these hard references, but first I wanted to explain the "simple" concept first.
@@ByteShock You still use interfaces. Just between the gameinstances and widget instead of enemy instances and the widget. This avoids hard references.
Really appreciate your videos. I got so many of your vids in a playlist I use as a beginner to unreal engine 5. Just started learning this engine about 2 weeks ago, and it's so enjoyable learning something new and actually being able to understand it. Never stop posting PLEASE!!
Thank you so much for your kind words! I'm thrilled to hear that you're finding the videos helpful as you dive into Unreal Engine 5. Keep up the great work with your learning journey, and I'm glad to have you as part of the community! 🙏
I'm intrigued, why would interfaces not be better for this? Wouldn't an interface send the same message to the blueprint and is actually easier to implement and to include other blueprints in the system? Especially if you have tens of thousands of actors.
Same. 😅
I believe there is some confusion between interfaces and event dispatchers. An interface on its own doesn't really do anything. It simply describes what functions a class should implement to be considered an instance of that interface. It has nothing to do with the observer pattern which is based on 1-to-many communication between subjects and objects.
In classical C++ the interface can also describe what events a class is publishing, which would have been helpful in blueprints. Meaning you would use interfaces as an additional layer between the publisher and subscriber but not as a replacement. Unfortunately that doesn't exist in blueprints though
Hands down best tutorial I've watched so far in my early UE5 journey. You explain everything so well. The first video I didn't have to pause and rewatch 100 times.
Thank you so much for your encouraging feedback! I'm delighted to hear that the tutorial was helpful for you as you start your journey with UE5. Your appreciation means a lot!
This is really kind of UE related content I've been looking for. Actually I'm pretty sure you did some kind of poll while ago or something and I was mentioning back then, that THIS kind of videos or tutorials or explanations is what I'm missing. I can't say I'm struggling, but there are times when I'm discussing my approach of designing some systems with experienced programmers. Thank you for this and I'm looking for more of this.
Hey there, thanks a lot for the feedback, I did indeed make this tutorial based on community polls and feedback, so if you participated in those, then thank you so much, you're the reason for this kind of content 🙏 and I'm really glad you see the value in it. I'll definitely keep em coming
Love these videos that resolve bad practices from other youtubers, amazing!
Thank you so much for your comment 😊🙏 I do indeed try my best to showcase good practices so that people don't end up with a mess and not know why. Glad you see the value in that
I don't know why it has took me this long to properly understand the event dispatcher but I am glad to have come accross your video. Explained the pattern and the technique in an excellent manner. Subscribed
Thank you so much for the kind words! I'm glad the video helped you understand the event dispatcher. Welcome to the community, and thanks for subscribing! 🙏
Thanks for creating tutorials that go beyond beginner subjects.

This is probably the best channel about UE. Thank you very much!
Thank you for your kind words! I'm thrilled that you find the content helpful. Keep creating and learning! 🙏
Thank you. Your Tutorials are sooooooooooo good.
I was trying to figure out how to deal with this exact problem and didn't realise UE5 already had built in features for it.
Please keep making tutorials on 'best practices' for common programming problems like this. They're super valuable.
You're very welcome! I'm so glad you found the tutorial helpful. Thank you for your kind words and for watching! I'll definitely keep making tutorials on best practices and common programming problems. Your feedback is super valuable 🙏
Great video man. Im learning UE5 blueprints and the way you explain stuff is great, clear and smooth. Also great advice to avoid problems later on. Thank you and keep up the good work.

Such a concise and informative tutorial. Really helps me a lot. Can’t wait to see more content like this.
Thank you for your kind words! I'm thrilled to hear that you found the tutorial helpful. Stay tuned for more content like this in the future! 🙏
Your tutorials are great! Im switching from Unity to Unreal and it really helps to re learn the basics. Keep it up and thank you!
You're very welcome 🤗 really glad to hear that! In Unity it's much easier to find these kinds of tutorials since there's so much info on good C# programming, but it's a lot harder in Unreal's proprietary blueprints, so I'm glad to be filling that gap 🙏
I asked somehting along these lines in discord a few weeks ago, its still been a bit of a problem. Now you made the perfect video! Thanks a lot.
That's awesome to hear! I do take all feedback into consideration when making a new video, so it could have very well been your question that led to this video. Glad you found it helpful 😀🙏
This is such a great concise explanation of how Event Dispatcher is like the Observer Pattern. I was "pretty sure" that is what it was used for before this video, but now I am very sure.
Awesome! Glad it helped you gain confidence in your knowledge. I will be expanding on this pattern in later videos to make it even more performant and efficient
Very nice video. I look forward to see the upcoming ones because I find it very interesting to learn how to use Software Design Patterns in Unreal/Game Dev for better code and which ones to use. Also very good explanied. Love your videos. :3
Thank you for your comment and your support! I will definitely create more design pattern tutorials. Glad you're finding the content helpful! 😊
Clear communication and explanation.. Great job Ali.. keep going man
Thanks so much 😊🙏 I'll definitely keep em coming
One thing to note, you don't want to decrement your enemy count variable because it can change if new enemies spawn. It's better to always get all enemies because the performance hit is negligible or have another dispatcher increase count when enemies spawn.
Thanks for the suggestion. In the next video in this series I tackled the issue of spawning enemies as well as killing them, make sure to check it out if you want to see how it's done
Best channel on youtube for UE5! Thanks for great content!
Thank you so much for your kind words! I'm glad you're finding the content valuable. Your support means a lot! 🙏
This was a very well done explanation and illustration, thank you!!
Thank you so much for your kind words! I'm glad it was helpful. Keep an eye out for more content in the future.
Amazing tutorial again. One of the better channels for all type of tutorials on youtube for sure
Thank you so much for the kind words! I'm really glad to hear that you find my tutorials helpful. Your support means a lot to me!
This is probably the best explanation on not just how, but also and more importantly, WHEN to use event dispatchers I have ever seen. I find a lot of videos for UE BP skip over the why in favor of the how and it drives me nuts. Sure it's just visual scripting. Except logic is still applied making the concepts, or "the why", still just as important. Without the why things like tick or delay get abused. Good stuff you gained a sub!
Thank you so much for the kind words! I'm really glad you found the explanation helpful. Understanding not just the how but also the why behind these concepts is crucial indeed for building scalable games. Welcome to the community, and I appreciate the support!
Great tutorial, enjoyed every second of it! Thanks!
Thank you for the kind words! I'm glad you found the tutorial helpful and enjoyed it. You're very welcome!
Thank you! This really would change my workflow as a begginer in unreal and will probably save me a lot of time.
You're very welcome! I'm glad you found it helpful. Always happy to hear that it's making a difference in your workflow 🙏
You could also update a variable in game mode class, the game mode could have its own event dispatcher and be called when an update occurs, and everyone listens to that ED in the game mode. This way you don't have to get all actors of class just the game mode. Game mode is accessible from anywhere so that would make it also easy to update the variables.
Hey there! What you're describing is the Observer Pattern using an "Event Bus" which is exactly what I'll be working towards in this series, but unfortunately to explain the concept the best way I can, I have to explain some other patterns first. You are already 2 steps ahead, well done 💪
I so needed to watch this yesterday. My work today needed this.
There is always time to refactor ;)
This is amazing for decoupling, will give it a shot with my current logic. Thanks!
Glad to hear that you found it helpful! Best of luck with implementing it into your current logic 🚀
Best Series in my opinion. Keep up the good work. ❤

This was great tutorial very well taught with easy to follow instructions and descriptions that help you to really learn what is being taught. I have learned about event dispatchers already but this made them more understandable to me.
Thank you so much for your kind words! It's happy to hear that the tutorial helped you gain a deeper understanding of event dispatchers. I'm really glad you found it useful.
@@AliElZoheiry I know this has nothing to do with your tutorial but I am working on a project and I am running into a issue I can not find a solution to. I have been asking around to find a solution but have not got an answer yet. Anyways I am making a character that can either be in third person or sidescroller with a camera on the right side. I have it with a enum that lets you switch between which camera is in use. I also have the code where you can switch between being able to move everywhere or just on the x axis. However, I can not seem to figure out how to activate the y constraint in code only when I set the player to sidescroller. If you have a answer for this that would be great if not no issues. Thanks again for this tutorial I have already watched another video and plan to go through more of your videos here soon.
Hey @@oscblade1691 Unfortunately I've never done sidescrolling in unreal engine, so I'm not sure what the issue is :(
@@AliElZoheiry that's fine thanks for replying
Fantastic explanation Ali, thank you.
Thank you Brandon 🙏😊 Glad you found it helpful
Thanks for the tutorial! Ive been looking for a way to include a remaining enemy counter for my retro shooter and this will work perfectly
You're welcome! I'm glad you found the tutorial helpful for your retro shooter. Good luck with implementing the remaining enemy counter!
This is awesome! Thank you
Thank you for your comment! I'm glad you found it helpful 🙏
I'm very new to a lot of Unreal Engine 5 and working within its BPs.
It's safe to say that I don't entirely understand everything here, but I do want to comment on the fact you explain things very eloquently and also mention examples of why this "Publisher + Subscriber," or "Caller + Listener," pattern is VERY practical and resource efficient.
I'm definitely subscribed and hoping that I'll be able to understand a lot of this in the near future. Haha.
Thank you for this!
Thank you for watching and commenting ☺️🙏 really glad you found my teaching style helpful, I do put a lot of time and effort into making sure that things make sense before I hit that record button. glad you see the value in that.
Amazing video! Thanks!
Thank you so much! I'm glad you found it helpful. Your support means a lot to me. Keep enjoying the content!
Very good video. I knew the observer pattern, but not how to do it in UE. Thank you! Excellent example too.
My pleasure 😊🙏 glad you found it useful
more design patterns and approaches please! great video 😁
Glad you found this useful 😊🙏 I'll definitely keep em coming
exactly the kind of thing I want to know, thanks!
Really happy to hear that. Thank you for watching and commenting ☺️🙏
Amezing.. Designer patterns tutorial series in game dev ...absolute insane :) very hard topic to explain in a way everyone can follow along .. absolute amezing and can not wait for the upcomming patterns :) absolute amezing work :)
Thank you so much for your comment 😊🙏 glad you found this helpful. I'll definitely be making more
This is awesome please keep giving more knowledge on making great games.
Will do 😊🙏 glad you found it useful
you my friend explained this flawlessly thank you
You're very welcome! I'm glad you found the explanation helpful. Thank you for your comment!
THIS right here is high quality teaching!! not a copy and paste video, ironically considering the topic; Software design pattern
Thank you so much for the kind words! I'm really glad to hear that you appreciate the depth of the content and my teaching approach. Your feedback means a lot to me.
Very good information! I used interfaces a lot, but as you mentioned, I created unneccesary dependencies as I needed references when calling interfaced functions. Thanks! Time to rewrite interactions!
Glad you found the information helpful! Rewriting interactions to reduce unnecessary dependencies can make a big difference in the long run. Good luck with the changes!
I often find that the most difficult part of learning this engine is just how exactly to go about things and the best practices. Stuff like this really helps bring clarity. I mean, even if I can figure out what an individual feature does, It is still very difficult trying to work out exactly how, or more specifically, when, to use it.
Never understood event dispatchers, or that little red box at the top right. Always get confused with most of the tutorials covering them, or they just seem to be missing something. This was really well done, and many things started to click. Only issues now are knowing how to use all the other options besides just call and bind that the event dispatcher has. When should I unbind, and when to use dispatcher over other things; Lets say for example, over interfaces. I suppose sense this is for observing when something happens, interfaces are just more for when you actually interact with things more directly. Like communicating to the button you are pressing, or the gun trigger you are pulling without specifically targeting a specific one. At least that is where my head is on it for now.
Hey there,
I totally get where you're coming from, Unreal Engine can be quite overwhelming at times. Event dispatchers and interfaces can be a bit tricky to grasp initially, but essentially event dispatchers are great for signaling when something happens, while interfaces are more about direct interaction. Knowing when to unbind and when to use dispatchers over other options does indeed require a deeper understanding of the context and specific needs of your project. Glad to hear that things are starting to click for you, keep at it!
Thank you so much!! I always saw the usual tutorials and I thought "there is no way I should reference other actors for everything. There has to be a better way" and yes there is. Now I know how to make a light turn green when I deposit an item quest.
You're very welcome! I'm happy to hear that the tutorial was insightful for you. If you have any more questions or ideas, feel free to share them!

Hello from France !
After 6 months of learning C++, I'm on learning UE5 learning journey for 1 month and a half, I just worked myself through Blueprint Interfaces to communicate between Target, Trigger, via Gamemode in my little practice aim game.
I had a hard time understanding how casting works even though it seems so simple !
