First and foremost, i apologise that the audio is far less than perfect, I have been having some technical difficulties with audio.
In this video, I want to introduce you to a pair of nodes that I find extremely useful in Unreal Engine. Set Timer By Function Name, and Set Timer By Event have many different uses, but in short allow you to create functions and events that run after some interval and/or loop. In this video we cover a few common use cases for these nodes, such as making a literal timer, making an event delay, and making an automatic weapon. There are a lot of pros to using these nodes, but also some cons to be aware of, so stay tuned to learn more!

finally got cleared up, was confused about return and differences between both, thank you so much!!
FIRST - I really enjoyed this deep dive into timers! Very important concept with so many uses that I'm very sure will help a lot of people make games!
It's nice to learn Blueprint from a programmer; I have been having some trouble grasping it due to it being so abstract. You break it down really well
Great video - Straight to the point and great use of examples
Hey man, i just discovered your channel few days ago, let me say that you have some of the best tutorials on Unreal Engine i can find on youtube. You explain essential concept in an extremely clear way and with great multiple cases examples! Thank you so much, i hope to see a lot more from you in the future :)
Thank you so much! I'm really glad you enjoy them. I definitely have more coming soon!
OMG the delay node was very useful. thank you
THERE IS NO FUCKING WAY I DIDN'T KNOW YOU CAN CALL AN EVENT WITH "FUNCTION TIMER" THERE'S JUST NO WAYYYY. Thank you
Great content, keep it up!
Terrific tutorial. Another comment for the algo here.
Great video as always! And indeed it was a simple tutorial until you dropped the bombshell in the end. What do you use to replace Event Tick?
This really depends on what you are doing. Again, you have to ask yourself "do i need this to run every single frame" if the answer is no, there's usually another way. A lot of the time you use custom events that trigger other events and so fourth. But at the end of the day, it depends on what you're trying to achieve. IF you do have to run something every single frame, from what I'm told, you're way better off using tick via C++ rather than trying to micro optimize tick in blueprints.
Keep posting, you teach very well. You have a careful approach to teaching that reduces the cognitive load on the other side.
In the end where you talk about Event Tick... The thing about Event Tick instead of using Timer by Event/Function Name, is because Event Tick is individually based off of your frame rate. Meaning if you had a multiplayer shooter where you and your opponent had an AK47 and let's say you had 60 FPS while playing and he had 30 FPS, regardless of how you set the RPM (Rounds per minute) for the AK47 globally, he would literally shoot at half your fire rate.
I was just wondering how to put in parameters for custom events within Set Timer by Function Name.
Is there a way for the timer to call functions or events with variable parameters inputs?
Not that I'm aware, plus how would you pass those values through? The events just getting ran on a loop by the timer, you wouldn't have a way to pass different values through each loop
12:00 negation of the time variable
To save anyone else that might do the same dumb thing I did - make sure you're not trying to create a custom event this way inside of a method. You need to do it from the event graph.
You can do this from inside a function, and use the "create event dispatcher" (or something like that - the one that gives a dropdown to select compatible events) node to call the event outside of the function
Question: Is there a reason to use a Branch on the "triggered" node of the IA instead of using the "Ongoing" and "Completed" Nodes? I used those 2 and eliminated the need to add trigger modifiers to the inputs, and removed the need for the branch node by using the "Completed" as a false and the "Ongoing" as a true.
Is there a drawback to this method?
It's funny, recently I had a friend doing this in his project and I wondered the same thing. To be honest with you, I just did it the way I'm used to in this case. I have not experimented with the Enhanced Input system enough yet to determine the potential draw backs if any.
@@TylerSerino I'm looking through your tutorials and, despite me learning development for vr, you've got some good stuff... I'm gonna give you a subscribe, cos there's really a bunch of stuff in your vids that are helpful :)
Is it impossible to make these timers work when pause is on? If not, is there any alternative?
the AI is telling me there is a "on Timer Expired" event...
Why do all “tutorial devs” slam their keyboard when typing, it’s like everyone is just trying to show off “I can type fast, see? I know what I’m doing” relax guy. We get it. You know unreal.
And way too fast. Slow it down to show what your actually doing instead of showing off your “dev speed”. We get it, you have more experience. Was such a annoyance to the video how hard you were trying to show it, I watched only a quarter through and said “screw this guy” and found someone that taught me, not tried to show off.
That’s why no one watches your videos bro.😂
?
Paranoid much? Highly doubt that he was trying to show off by typing loudly and fast. It's more likely he has a mic directly on his desk on top of having a heavy hand. Not everyone is willing to shell out for a microphone arm and dampeners to reduce their keyboard/mouse sounds.
Cause you ain't got time to be nice to the keys
