#15 | IENUMERATOR & COROUTINE IN UNITY 🎮 | Unity For Beginners | Unity Tutorial

[@Tarodev]

Wow, I have been sleeping on your channel. I randomly chose this video to see what you're all about, and I really enjoyed it. Practical examples with lots of tips nestled within the explanations.

[@Dani_Krossing]

Hehe thank you, means a lot coming from you. 😊 You are the one I use as a "benchmark", when I imagine where I some day want to be "Unity scripting knowledge" wise. 🙂

[@Tarodev]

@@Dani_Krossing Oh ♥ You've commented a lot on my content, and I always enjoy your take. Not sure why it took me so long to click your name. Your facecam setup looks fantastic, I really need to up my game in that department.

[@Dani_Krossing]

@@Tarodev Thanks hehe. 🙂 A eye melting spotlight 👁🔥, and a blue lamp does wonders. 😅

[@TheGrimmy]

Ah man, this is SO helpful! I had these problems a LOT with my old code and I thought I just broke stuff along the way. I went back to try and fix it, but obviously didn't know about IEnumerators! Thank you so much for covering this with such a thorough explanation :D

[@Ooga658]

Thank you so much for doing these. These videos are engaging, fun, and super easy to understand. I can't even explain how much this series has been helping me, can't wait for more!

[@TheGrimmy]

This exact example is(I'm pretty sure) used in games like Celeste because players press space, an animation happens that teleports players forward and players obviously can't move during the teleport. It's a matter of 0.2-0.5 seconds, but it still happens, haha. Very interesting example!

[@theUnfrench]

Tried other vids to understand this. None were as clear and easy in their explanations as you are here. I appreciate the help 🤙

[@windup247]

This is so well explained, thank you Dani!

[@shonixgaming3076]

THANK YOU SO MUCH FOR THIS!!! I’m brand new to this and started making a run and gun 2D side scroller as my first game. I wanted my character to keep his firing arm up for a few frames after firing, while also keeping it up should the player keep firing it. I spent HOURS trying to figure this out, until I stumbled upon this. Finally solved my problem but also learned about coroutines. So thank you again. XD

[@东皇太一-s4g]

ty， you teach is clear。 it help me

[@crossing_lears]

Thank you very much for this very good lesson. I used to ignore videos about coroutines but when you emphasized and explained that it improved game performance got me interested to it. You also explained it very directly, thank uou!

Man your code videos are great Dani im learning a bunch. Thanks for the effort explaining this stuff its very apreciated :)

[@HazardLaser]

This was a very informational video! thankks so much for being better than my professors :p

[@KonigTheV]

Thank you!!! This video has helped me a lot.

Thanks a lot, you are greatly helping me and a lot of lucky people that found your video :)

[@Another_me1808]

Very helpful explaination , thanks

[@alessiodibella2003]

Very useful, thank you!

[@anttiv7109]

I would love to hear more practical use cases for this.

[@theBestTwin5321]

Thank you so much for this!!! Great tutorial!

Do you do any conferences planned in the Copenhagen area?

How do you run coroutine out start, Ontrigger or update. I want to use a button to start a coroutine.

[@nathanholmes3334]

Hi there, I found your channel when I was looking for a place to learn C# and I watched the tutorial you made a few years ago and loved it it was great but I had a question that popped into my mind after I finished watching that series and that was how do I learn to code a players health system in unity or give the player a inventory system I want to make games but there isn't any tutorials that I can watch learn any of this I have seen other people code health systems or create a inventory system for the player like it's second nature so surely there's somewhere I can go to learn this can I get any recommendations please?

[@krzheski]

Great tutorial! Can you do a profile page tutorial for the login system please?

[@nathanholmes3334]

Also I am learning more C# on code academy if anyone was interested in where I am learning

When you cancel the coroutine, the player has already gone through the disabling of the movement, so when you cancel the coroutine, the player stays still?

[@Dani_Krossing]

That's right, but in a coroutine such as that one in my example, you wouldn't cancel it mid way. 🙂 And even so you can't really hit the cancel key fast enough since we are talking 2 frames. But let's pretend you did set it up so you could cancel it, you would just add a line of code that enables the player movement again when you cancel the coroutine. It was really just an example in order to show off coroutines, and there are for sure 10 other better ways of doing something similar then the way I showed hehe. 🙂

[@Analyzer_Games]

thanks you

[@Exizos]

Completed all 17# tutorials that you've made and I learned how to apply data types and other stuff but I'm still sad because I just feel too stupid for scripting because I do really bad at math.

[@georgehanna8768]

What about using invoke?

[@Dani_Krossing]

Coroutines provide better performance, and allow parameters, which invoke doesn’t. 🙂

[@georgehanna8768]

@@Dani_Krossing Thank you!

[@anythingpeteives]

You said that IEnumerator is part of .Net and that it allows the user to iterate through something. How does it know in this case that it is going to iterate through frames? Is that it's only purpose within unity?

[@Dani_Krossing]

IEnumerable in .NET is used to loop through a non-generic collections. For example classes or lists. Unity uses this feature so that we can create these "time delays". You can read more about it here: learn.microsoft.com/en-us/dotnet/api/system.collections.ienumerator?view=net-7.0

[@senl9429]

I've been stuck in the debug coroutine for a day now and still can't find a solution. VS2022 says "flame not in modele" I have tried all the methods that can be found on the Internet, and I have also checked some communities. Can anyone help me. This is machine-translated.

[@Mport-UK]

If you need this to only play omce. Put in start and not in Update! :)

[@Natsnok]

Great tutorial :) I wish you wold make a tutorial about public variables and the problem that some times the public variable is saved local in a other script. This is one thing no one could expane to me. But i think you could

[@klaus117gaming]

Is it just me or Dani looks like Elon Musk?

[@cm16533]

to summarize, would you say the main use of a coroutine is to control the flow of code? It seems like whenever I see loops used in people's code, it is within coroutines.

[@firepenguin9919]

Im new to coroutines in general, but I heard that they are also used for functions that would normally be in Update, but dont benefit from being called every frame. For example a timer in seconds. You could code that in Update but a coroutine skips all the unnecessary frames and just activates every one second. For a timer you'd use a while loop

[@sebaferrari_tattoo]

[@wearwolf4202]

How can you use a coroutine when someone enters a trigger like onTriggerEnter, or onTriggerStay?

[@Dani_Krossing]

Just use the StartCoroutine() inside the OnTriggerEnter function :)

[@lorshim7669]

Hello sire My you make videos with return item when customers want to refund in php

[@Dani_Krossing]

Sorry but I don’t do much more in PHP tutorials. 🙂
