your optimization videos are genuinely great! I'd love to actually see a full project that has its logic done "the wrong way" compared to a build done with this approach and just compare the performance between the two on low end hardware good stuff!

Hi everyone, So, in my current project, I replaced all the "event tick/delay" setups with "custom events," potentially using a timer. Before coming across your tutorial, I had read that using "ticks + delay" was a way to ease the CPU load. I had around 40 of them on my main blueprint and 30 on one of my vehicle blueprints. Before switching to your method, my performance stats were: World Tick Time: 7.64ms Tick Time: 7.23ms Blueprint Time: 4.54ms After changing everything to your method: World Tick Time: 4.22ms Tick Time: 3.78ms Blueprint Time: 3.46ms That’s a 40% improvement! I’ve got the screenshots if needed! Thanks :D

Потраченного времени жаль. Пятикратно переваренный кал

I'm trying to get my character to cross over food to heal themselves and have the food disappear, but the food will still disappear even if the player's health is already at 100%. Any ideas how to stop this from happening?

Hi, thanks, very usefull and well explained ;)

what nonsense, just use a delay and a sequence if you want to continue something else while the timer is waiting. 2 nodes and done, no need for that whole timer setup and terminating

This tip is a bit heavy handed but generally okay advice. If you're doing a single player, there's nothing wrong with Delay, use it as you wish, especially helpful using it with a duration of 0 since it waits 1 frame, helps with spreading stuff over multiple frames, like in big for loops where you want to avoid hitching by doing too much in a single frame. But in multiplayer games you should avoid Delays yes, use them only for debug purposes to check if your code executes in a bad order but for actual implementations you should avoid it. If your multiplayer code requires delay to work then it's written poorly.

Very good work! The course referenced on Udemy is third person though, is this included? It's obvious you know your stuff well from watching a few of your videos. I'm sure that even I could learn some things from you. I'll be getting both your courses soon as a sale pops up on Udemy. Any plans to make more courses? Keep up the great work!

Good advice, although you repeat yourself to much. Thank you for help!

Is there a video with optimized player health functionality somewhere? I can already see the videos from the series from #6 and #7, but I don't see the ending of the topic from video #5

Hey i have question why not 5.5?

I noticed that you use a macro instead of a function for the WASD controls. When is it better to use a macro versus a function? Perhaps this could be a topic for a new tutorial. 😉

Can you help figuring out this? How would I trigger a few actors at a distance? Lets say I cant use overlap or line trace. I just want to hit a switch and turn on a buch of lights (or open a bunch of doors) Is there a way to do this without "get all actors of class"? One idea that comes to mind is to put the interaction code in the lights. Maybe they can use "player character" to trigger an interface event that checks if the player interacted with the right switch? Or I was thinking that I could still use "GetAllActorsOfClass", but instead of a specific actor class I could use the base actor class. Then use tags. I dont know if that would make it better, but Im not sure how to sample a bunch of actors that are afar. Thank you!

I always feel that using Delay is the wrong workflow. Thank you for highlighting this so clearly and providing a good example of how to handle a timing case like that!

I dig your youtube channel trying to find the solution for this case, is it a external course ? if not, can you put the solution as a link in the description pls. Thanks!

What do you mean by binding ? what is it that's wrong? I'm not advanced in BP so sorry if I asked a beginner question

What about making an ammo counter? Is ok to bind this?

Hello, Do you have any course or tutorial about how to do those?

Thank god! This is the VERY FIRST TIME someone explains why casting is expensive, no other tutorial I've seen (even from official Epic Games instructors) explains this and how to bypass it!!! Instant subscribe

can we put different interact widget pop up each BP? like press E, F, G

much needed course

Umm can i use it for something that I'm sure that alway load in all level and i cant use BPI like my AI Controller? i have to casting it? I dont know much about event dispatcher if you do tutorial about this and show how it qork and example to avoid consuming Performance it will be great

I am sorry but your video has wrong information as someone who has worked within the engine since udk3 and works mainly within the core of the engine, I feel I have to put a correct statement on this... The delay node and custom event with timer serve different purposes and each has its own strengths. If we dive into the technical details. The custom event with timer can be less performant than the delay node in certain scenarios. This is because the timer uses UE's FTimerManager which maintains a global list (or queue) of active timers... every frame the FTimerManager iterates through its timers to check if they have expired and if so calls the associated callback this system adds flexibility but introduces overhead especially when managing a large number of timers on the other hand the delay node is lightweight it does not rely on FTimerManager instead it uses a latent action within the blueprint system that resumes execution after the specified delay this makes it more efficient for simple localized delays both systems have valid use cases: use delay for straightforward one off pauses and custom event with timer when you need more control e.g looping, dynamic start/stop however it is incorrect to assume that delay nodes are inherently less performant than timers they are actually more efficient for basic delays due to their simpler implementation

omg i love you man, absolutely saved my life today

Trash clickbait …delay is good do not misguide

How about using HasInterface? Does it cost more than HasTag?

Thanks for the video.....

Just to add when to use casting: Casting is for working with classes and inheritance. So if a child class has a function you want to call, you have to cast to that child class, before being able to call that function.

Your example is absolutely terrible. It is only something beginners would do, so even if you are right, you will NOT convince anyone with this example. But what I'd rather like to know is, how about the Do-Once-Node ? Should that be avoided too? Or is it just fine to be used?

Thanks for the tutorial, it helped me so much!

U got a subscriber Sir, nice viedos, keep it up

Great content, just bought it. The UI part is not covered in depth by other courses. This course will make a big difference on my widgets

After having finished the first one a couple days ago, I literally had it in my in basket and bought it before I even looked at it.

yea thats really tutorial that no one done before, defo will buy it.

Excelente vídeo, from Brasil.

My brother i think i understand everything right ? the video is super great, now if i understand correct in deeper if i want to get a variable from the current bp to another bp i just implement the interface in the current bp and make the event like set health with has a output from the interface and when called from other bp i just put the number trough input in the message and that will call that custom event for setting hp with the hp i wanted in the message input so no CASTING brother is that right ?

Great Video Vlatko! I find Interfaces unusually difficult to understand. It is just me though I guess.

Interesting, where is the lesson 2 of this ?

My 2 cents: Join Branch with 'clear and Invalidate' and skip one step. Its necessary 'Clear' after one single loop ?

Can I use this logic to create harvestable tree?

Excellent tutorial!

I heard if the casting is directed to something that will always loaded in the game such as your character, its fine to just keep casting that particular thing. But if its temporary things like normal enemies, once you cast it will still stay in the system and eat up the memory.

what is best optimized way to spawn NPC AI that roam around?

There's nothing wrong with delays, they are simply callbacks to execute async code. Timers do not accept parameters, which is a big problem with UE imho. Timers can introduce race conditions and create really hard to find bugs. Delays are great for things in 50-250ms region to delay gui updates.

I like your videos. Thank you very much.

Can you make full tutorial how to make optimized 3rd person shooter game? I want to Learn what is the most optimized way especially with the gun,shooting,and bullet system. I will buy the course if it’s on udemy

it is usefull for destroying actor but actors contain code you cant perform without casting

Great video - thanks! - However lets say we are interacting with an actor that implements an interface - I have to cast it to a type of that interface to be able to call the methods defined on that interface! - how would I do this without casting? - seems the implementation of casts in blueprints is badly implemented!

Fantastic video. Thank you.

Блин, извини ты угораешь что-ли? Прежде чем учить возможно нужно мать-часть поучить. Извини не удержался. Не вводи людей в заблуждение!
