UE5 Blueprint Tips - Event Tick Performance

[@randombleachfan]

I didn’t know UI binding was an event tick, thank you for showing us that 😊.

[@RobinDale50]

Yes I think I stumbled on this by accident. I have been learning UI/widgets and once I started messing with bindings, I was like "oh, great! it will just automatically update whenever the variable(s) change!" and then I thought "that must run on tick or something, as it is constant"

[@DawnBriarDev]

Excluding UIs and the player controller, I disable tick by default as I've never run into a case where an event can't be done via context (trace, hit, sweep, reference from somewhere else), or by setting timers for specifics tasks (like having multiple event ticks, with the specific interval best tuned for what they need to do.) Given that tick runs on every frame, you generally want your inputs and the things you input into (UIs) to be on tick. You can make a lot event driven, but there's diminishing returns past a point. However, most gameplay context can be event driven by something other than tick. Though, feel free to slap tick on just about anything during prototyping while you're adjusting to event driven practices. Nothing wrong with that.

Thank you for this. I was trying to look for ways to optimise my game to allow for large numbers of enemies and this video was recommended for a way to set actor AI to not impact performance by only making checks when they need to. Very helpful and clear, and learned some other great tricks along the way too

very nice explained im going to make use of this in my own project because here and there i see some flaws, definitely subbed! EDIT: HOLY SMOKES! okay, i have a car with a Nitro UI costantly updating and the engine sound ofcourse in deltaseconds, within 1 minute it became unplayable on a very decent machine, using your tips instantly pushed the game to rock solid 120fps with 8ms, just like it should. i REALLY appreciate this video as this was a very big trouble point for me in the past!

5 tips that really got me going in my next project, thanks! I'm actually rotating a ball on kick, so that came in handy!

[@sufifrank]

You can also use Timelines for rotating/floating objects and enable AutoPlay and Loop

Man, you are genius, thanks a lot!

[@nazmihanarslan8498]

Useful video thank you.

[@raivo4716]

Very useful. Thank You.

[@garrytalaroc]

Wow thank you so much! There's so much I have learned.

[@vladsafronov5952]

thank you very much for nice tutorial!

[@rifat.ahammed]

Great Video. Thanks a lot

[@Kombatant777]

It was a very helpful video thank you very much

[@Studio_Beats]

Fantastic tutorial, thank you very much!

[@Troyseph]

Fantastic video, made me a subscriber!

[@glormond]

Great tutorial! It's a pity that many other authors don't warn against using Event Tick in their tutorials.

[@lloydmilton]

wow loving the tutorials man.... :)

[@ZarconVideo]

Tick can really hurt performance, espesually if you put it on something heavy. Use Event Timers. In most cases a looping .1 time is going to be just fine.

[@nevfelemrecicek]

I love that video thank you!

[@TaLila360]

Hey, thanks for the video, it was very informative! I was also wondering, if line trace for object is always on, does this influence performance much? I look forward to another video with performance tips.

[@DawnBriarDev]

It's a question of scale. If you're tracing one line per frame a 1980s calculator can keep up. If you're tracing 1,000 per frame you might have problems. Optimization is all about balance: There isn't one setting or rule that will automagically make things run better, it's about allocating many different resources in a way where one doesn't aggressively halt the others. That, and abstraction: Sometimes, a very roundabout way of solving a problem form a human perspective is a very straightforward way for a computer to do it. Over time, you will gradually learn more and more about those of these considerations.

Hi, my custom event are not set, I did exact same set up and connection, it outputs timer start just once. If I use event tick instead of event begin, it prints 60 times a sec...any clue why it dont do like you with event begin play ?

[@DawnBriarDev]

Not sure what part of his video you're citing, but print string nodes contain a "key" value. If you stick a name into that key, the string won't repeat. Example, key a print as "health", and even if it prints every frame, it will print "Health: (string)" in the same place every frame. It won't move and won't print duplicates.

[@gil6970]

On anim notify state blueprint , is the override receive tick the same as using an event tick? I’m using an anime notify state and put override receive tick. Would it hurt my performance?

[@furkannarin2844]

everything you use on tick has a pretty high chance of impacting your performance a lot depending on the code. if you dont do complex things every frame it wont, if you loop an array every tick you will suffer a lot

[@lovinghand7325]

THANK YOU SOOOOOOO MUCHH

[@crazyguy7585]

hey sir i am ur new subscriber thanks alot for amazing tutorial. i saw a orange Cube is amazing material can u teach that material or can u share where i can get that type material.

[@unrealitybites763]

You're welcome. The material I used for the lava cube was one that already exists in the engine... /Engine/VREditor/LaserPointer/LaserPointerMaterial

[@pimeine]

Damn I though that UI bind was super handy never noticed it was a tick lol I was mainly using directly the "variable bind" so I set it when needed on an event update, I think this one doesn't tick each frame. I think it's what you did for tip 4 but you didn't showed the widget BP and from tip 3 we see that you set the variable in an event inside the BP. (Personally I don't use event but I understand it would make the bp easier to understandt) xD
