Unity How to structure your code with UnityEvents - Tutorial

[@TwoVera]

The best event tutorial I have ever seen. I made such a sophisticated inventory system and designed the GUI but had zero idea how to keep them decoupled. I was able to setup everything in minutes. THANK YOU.

[@helciowagner6101]

I've seen a lot of videos and texts about Unity events, and I should say: this is the best I've seen. Simple and precise. Congratulations, man!

[@PeterMilko]

The production is amazing man!

[@SoundMinded87]

It's not really. It's distracting to the viewer trying to get what he's teaching. The drawings are good though, they help.

[@roguerotkosky6213]

Actually such a good tutorial, I was stuck for days reading about unity events and how they fit into scriptable objects and watching Unite 2017 videos to figure this out. And all it took was 20 minutes watching this video and I finally get it! Thanks!!

[@rongreen385]

Superb tutorial! I've watched lots of tutorials about UnityEvents but this is the best explanation I've seen. It all makes sense now. Thanks.

[@Arkan77N]

Hey! Awesome job. I didn't see anyone on YT who talked about this topic. This and your others tutorials are amazing.

[@musicdudem6673]

Awesome! Good to see this still going Will you cover inventory, dialogue and quest systems?

[@CodesnippetBiz]

Wow...I'm really impressed by the quality of this tutorial! Honestly one of the best practical tutorial on how implementing events logic into code... thanks a lot man! And obviously I've subscribed to your channel!

[@Fishpotatogames]

Thanks for this! I saw it today and, while I have been using events, I have not been using them in this manner. I've already updated some of my code. This is a definite rethink on how to approach communication between components.

[@this-cris]

Thank you for making in depth videos about coding. Looking forward to you scriptable objects video!

[@ChethanBhandarkar]

Too much knowledge in one video, explained neatly! Subscribed.

[@martinds93]

Really nice video! I watched the hole thing. Thank you very much, you cleared a few doubts about UnityEvents.

[@cuznerdexter]

This is a great simple way to explain UnityEvents. Great job! Easy to visualize. paper and pens is a great idea.

[@erato1]

Really great video. Will start to look into using this technique. I was previously just using C# Events.

[@artificialdumbness9003]

Amazing , very simple and clear explanations

[@mehmedcavas3069]

Ohhhh thanks a lot. Was looking for that for a lot of time but couldnt find a good tutorial. Thanks 😊

[@skippythemagnificent8103]

Great channel, got my sub straight away. This is a great well thought, planned and executed tutorial, many thanks for the effort :)

[@menyus777]

Yo, intresting concept, just a side note static classes are not initialized when the the application starts, only they type informations is loaded, however it is guaranteed to be loaded and to have its fields initialized and its static constructor called before the class is referenced for the first time. This is important because this can produce errors when the class, for example has inner Monobehav class. Luckily you can force run static constructors this way: System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor(typeof(MyStaticClass).TypeHandle);

[@kailastnam9793]

New vid!!! I’ll edit this after I finish watching.

[@matthewdaugherty5207]

Thank you, this is exactly what I was looking for and very clearly explained!

[@Notreal76]

Your Tutorials are great, thank you :)

[@PeterMilko]

Do you need to remove the event listener on Destroy?

[@CouchFerretmakesGames]

UnityEvent uses weak references so you don't have to worry about removing listeners.

[@Juke172]

Very nice and informative tutorial. Is there any advantage to using this or event Action from System library? At least the syntax seems simpler to understand.

[@CouchFerretmakesGames]

UnityEvent is more forgiving because it uses weak references so it handles most of the work when objects are destroyed (that's why I chose this to teach instead of C# event). You won't have a hard time when you forget to remove destroyed listeners. And it's also native in Unity, so the Inspector fully supports it, but I wasn't showcasing it the video, maybe sometime in the future. :) However, I guess UnityEvent should be a bit slower than C# events, but I don't think it'll be a problem in most of the applications.

[@Juke172]

CouchFerret makes Games looking at them side by side they work in similar way and if you have any need for more performance later on, the change from unityevent to system.action is pretty straight forward. Of course the basic idea of using events rather than accessing other gameobject’s components is a improvement itself.

[@WagnerGFX]

When testing a system I made using the C# EventHandler the message count reached around 1 million per frame (that is A LOT), while the UnityEvents results were quite smaller. But they both are very useful, specially considering things like performance, weak reference and inspector integration. I think the best approach is to consider the scope of the game and the development usability necessities before deciding which to use. This guy made an extended performance comparison between both types (in 2016, things might have changed): jacksondunstan.com/articles/3335 For reference, this is my project for a central Event HUB that uses EventHander: github.com/GFX5000i/GameEventSystem

[@videoguy640]

Wow, had no idea Unity had this implemented. I implemented my own observer pattern, I probably should refactor. Thanks!

[@brycedash2177]

I know Im pretty randomly asking but does anyone know a good place to watch newly released movies online?

[@zekeleonardo48]

@Bryce Dash flixportal :P

[@brycedash2177]

@Zeke Leonardo thanks, I signed up and it seems like they got a lot of movies there :D I appreciate it !!

[@zekeleonardo48]

@Bryce Dash No problem :D

[@ourteammate]

Sorry, I am late this time. But I really needed this one. I know how to code things and make them work but I dont know how to structure them or you know what's the best practice to implement a big system for your game. Thank you🙏

[@everabyss]

That's why everybody is here!.

[@mannymanny1567]

Better performance with UnityEvents or native c# events ?

[@RomanPapush]

Awesome video, mate! 🙌 And just in time, cause I seriously need to brush up on my events :D P.S. What's that black bottle in the background I spy? ;)

[@CouchFerretmakesGames]

Hehe, CouchFerret merch!!! JK :D Fun fact, only the second half has it cause' the first half was shot before Unite :D PS: The next time when I'll be drawing stuff again expect a few new stick figures to show up ;)

[@RomanPapush]

@@CouchFerretmakesGames Haha, but you made it so seamless! Would have never guessed :) Oh shiiieet, hype! :D

[@sebastiansanchez2158]

Lets just type 42... Just the The Answer to the Ultimate Question of Life, The Universe, and Everything... Great vid!

[@serialchiller9183]

Can't wait for the next video!

[@ajaygamedeveloper6148]

The best explanation of the event system

[@sudhanshlone8284]

Perfect Timing!!

[@ashishkmr]

Awesome explanation, thanks a lot.

[@itstwilight7417]

Is it easier to use unity events or c# events?

[@ChethanBhandarkar]

Hi CouchFerret makes Games, Please make more videos . I like your way of teaching. Unfortunately you stopped making videos.

[@rashiddev7545]

Great video

[@BurakNevruzoglu]

Awsome video!! Just curious , will ECS job system remove this logic?

[@PeterMilko]

You forgot to add me, jk. But next yr ill be doing unity tuts too!

[@CouchFerretmakesGames]

I can't wait, man :)

[@Nrodriguez29]

I did basically what you did on the video but adapted to my game, instead of the arrow script I have a UI script that is invoking the events, until then everything was working fine and I was happy with the result as I see this as a clean code, however, when I try to do the opposite (invoking an event in the GameLogic Script and listening to the event in the UI script, the event is never invoked or received I tried to debug and did everything but couldn't find a solution, any idea?

[@moncicis]

Hello...do you share the script in that video?Thank you in advance

[@sashalinaarts375]

Lol. I read forums about not using SendMessage and now a dedicated video comes out ... just in time to check about UnityEvents uses.

[@shawnw86]

What's the difference between using UnityEvents and C# events, for example public static event Action DestroyFinished = delegate { }; and then calling DestroyFinished(arg1, arg2, arg3) ?

[@taddeustentakel8598]

Can some1 explain me, where is then the exact difference between C# EVents? arent they some the same??

[@dempyy]

Are you hungarian, tho? Your accent is really similar to a hungarian accent. (P.S: I am hungarian. :3)

[@CouchFerretmakesGames]

Yep :P

[@angrygeri7026]

LETS GOOO HUN GAME DEVS

[@Ivcifer]

7:53 when I throw my current project away and start a new one

[@TheNamesJT]

could you do a simple 2d game series but still use intermediate/advanced scripting? games like hyper casual,clicker/incremental or like simple games you see on windows store, and Kongregate. For someone learning unity following your rpg series is a pretty big project if said viewer wants to expand or even branch away from that and implement what they learned...Feel it would be easier if you taught us smaller projects. also, not hating on your rpg series just isn't for me but i do like how you teach just wish it was simpler games.

[@YuriNoirProductions]

sorry for asking this here...but here seems to be an active community who cares about unity pixel stuff.. the tile palette seems to be broken in Unity 2019.3b and not usable at all....after dragging in tiles they do not appear in the tile palette yet the . asset files are created. As this is one of the most basic features of 2D in Unity does any of you may have figured out a workaround for now? Unity itself knows its a bug but they dont they anything except of "its beeing worked on"

[@gadgetboyplaysmc]

Would your example still be possible without using UnityEvents? But instead just raw C# events instead? I heard UnityEvents are slower afterall. And all of the subscribing/unsubscribing you did was via script. I've also read that one advantage of UnityEvents over C# Events is because they're serialized into the inspector at design-time: www.reddit.com/r/Unity3D/comments/35oekm/delegate_events_vs_unityevent_which_one_is/ Definitely wanna get your insight on this.

[@SoundMinded87]

Some good insight into UnityEvents. Well explained! But your constant jumping between video shots is very distracting! It would be much better if you stayed on the coding screen with your face at the bottom right or something(and cut to just your drawing examples, they're a nice touch btw). You don't give enough time to look at the code and allow for absorption. Your office is nice but we're not here for your fancy setup. Again, your explanations on the subject matter are great! Just all the sporadic edits make it hard to focus on what you're saying. Cheers.

[@mg70gaming66]

Hey you didn't include *insert favourite KZbinr here*

[@dhyskRand]

great video, loving the series and its really helping me.. except one thing. The view of the code on the laptop. I can't see anything just show me the code. It does look nice but it's impossible to read in smaller windows. Very frustrating to find the few seconds of the code full screen so i can see it as well. I do love the addition of the explanations on brown paper though. those are great
