For FREE?? U don't know how much we value these courses brother

[@The123Adrian]

He know

[@khurum]

but not complete, it makes sense of course it must be some really tough work

[@vp3275]

One hour ago I type "ECS tutorial" and nothing recent pops up I go take a shower, come back and my wish has been fulfilled, amazing

[@BlueDuck-vv3eu]

You are so very generous to the aspiring gamedev community. We appreciate it!

[@TheMightyKawama]

The thing that genuinely amazes me about you is your consistency to your beliefs, that education is important for everyone that you'd even go as far to release these courses in full here on your channel. If nothing more than inspiration for game development and learning coding - you're an inspiration on how to stay true to what you believe in. Thank you :)

[@LoneLuminaryDev]

I just wanted to say thank you for helping people like me who can’t afford paid courses. I’ve been learning game dev for three years and learned so much from you. Your effort means a lot! I also try to share your content with others as much as I can because I think it’s really helpful. Thanks again for everything!

[@sebandres]

Such a no brainer to get your full course! Keen up the good work and giving back to the community!

[@w1-w2-w3]

I just finish watching your previous 1hr 27min DOTS video. Now you just upload the new one. Thank you so much, sir. Thank you. 🙏🙏🙏

[@upprrdimensions892]

I am so happy for your channel's growth

[@cleverai2270]

Thank you very much for this detailed free DOTS course! It's been a while since I used DOTS in 2021 for my free universe simulation A Hole In Space, so I am eager to see how it has improved since then. Moreover, I will try to create with the new DOTS a more performant vegetation system than the standard Unity terrain one. Let's see, if this is possible. I will post my results on the Unity Forum later then. EDIT: Holy guacamole is it fast! I just did a simple test run with 20.000 trees with about 80 million vertices. First as terrain, the CPU takes about 25 ms to render. Second as GameObjects (GPU instancing on, static batching off, otherwise the GPU and RAM went full), the CPU takes about 20 ms to render. Lastly, just converting them to entities by putting the tree GameObjects into the DOTS Subscene, the CPU takes about 5,7 ms to render, about 4x faster! Unfortunately, I had to switch the material to the standard HDRP one for this test, as the custom shader does not render as an entity and the Editor is not happy about so much objects, especially when you edit the prefab and it needs to update all its instances in the entity subscene, the RAM usage goes through the roof. But, that looks definitely promising.

[@MarcBomber]

So much value ♥

[@MarcBomber]

Learned a lot and cannot wait for the IJob update.

[@CodeMonkeyUnity]

Many thanks for the super thanks! I'm glad you learned a lot! Thanks!

[@JustATortoise]

Thank you for these types of free courses. I was waiting for one for DOTS, so this is a blessing.

[@mahanthkanaparthi6087]

Maximum all of the basic functionalities we use in monobehaviour approach are covered in this ECS DOTS approach including physics. I have searched a lot for a DOTS practical tutorial. All are outdated and not with detailed explanation like this. You are a savior to us working on Unity 3D projects. By the way I love your voice. Your voice is an asset for this channel.

[@Bumiin]

I was learning ECS for one week from random tutorials, totally confused. I made a small project, but any change takes me hours. Now I have new hope-it's you, Code Monkey! Thank you :)

[@CodeMonkeyUnity]

I hope you learn a lot!

[@sebandres]

Hey Hugo, looking at your paid course, one thing that I think people would really benefit from is a module on Unit testing. I found it super valuable to cover at least my more complex logic with unit tests so that it doesn't break when refactoring or improving. I couldn't see any module that was focused on that (although I haven't finished yet the whole thing so apologies if it is covered inside another module!)

[@mattn5933]

Hurray! Thank you so much for making these free tutorials

[@EightLittleBears]

This guy is an actual treasure. Easily the best game dev channel / teacher out there!

[@CodeMonkeyUnity]

Thanks! I hope you learn a lot!

[@oguzhanoguz2363]

Bro, thank you so much for this amazing tutorial. I really like the way you teach by focusing on real features, bugs, and problems. I've watched many tutorials about ECS, and I can confidently say that this was the best one. Thank you for making this tutorial free; it’s a truly great contribution to the community.

[@StratoChigo]

Yes! I was waiting for this! Thank you Hugo, you're the best!

[@All_About_Portfolio]

Finallllyyyyy its releaseee.... i was waiting for this for a looooooonnnnggg timeeeee!!! Thank u Hugo!

[@GameAlchemistLeo]

Thanks a lot!! I was waiting for it

[@Dilithium1]

2:00:41 You are so good at teaching these core features and how it all works, thank you so much for this course! I always have difficulty sticking purely to documentation without an example project to show systems intertwining or working together, so this has helped me so much to understand how it works so far!

[@NotAZocker]

Only 2 hours into the course and it's just as amazing as your free Unity Course. I love your ideology of free teaching materials for everybody and you're definitely one of the best creators for Unity out there. Keep up the great work and I'm looking forward to what the future has to offer for you, hopefully only good things. Greetings from Germany

[@EnvArtistRupesh]

Wow that’s amazing! 7 hours of content for free??? Thank you so much code monkey 🥺❤️

[@jakubwawrzynczak774]

I just finished watching your previous tutorials and you just upload next 7 hours tutorial

[@gunnarherbert9778]

Thank you so much for this free course! Hopefully the algorithm will understand its value!

[@whitefox2k]

This codemonkey is the real wukong 🙌

[@hinterlandr8638]

Your work here secures your place as a community leader. Thank you.

[@ThynkTekStudio]

dude's creating an awesome Course for a fair price, dude decides to get even more awesome by offering a huge portion of the course for free on KZbin A Legend

[@mehmedcavas3069]

this will be an awesome weekend :D

[@abdelrhmanhashem3256]

you have no idea how odd to see you make this right as i needed it, i was just getting in DOTs and searching for new tutorials and the newest was about 6 month or more and DOTs changed a punch since then, then after 1 day i find you making this video and I'm shocked ^_^. Thank you.

[@CodeMonkeyUnity]

Nice! I hope you learn a lot!

[@masterneme]

Thanks, you're the best!

[@yurybatsyuro8293]

Good plan for the weekend!

[@joll98]

2:45:47 we can switch from timeline view to hierarchy view , there just type "mover" and it will filter it out and once selected switch back to timeline view to find it easily

[@joll98]

i find hierarchy view a bit easier 😅

[@mikhailhumphries]

Can't wait to go through this

[@PrzygodazUnity]

Just bought your tutorial and joined discord ! :D Thans for the good job

[@CodeMonkeyUnity]

Thanks! I hope you learn a lot!

[@ratel-ratel]

Epic! Thank you for your amazing work!

[@Pedroxqr]

you are awesome man really special thanks for free courses❤❤❤

[@AndromedaTV]

appreciate, I'm 32 years old. I have no point what i want to do. now i just begin learn c#. Thanks for sharing this.

[@kostariev_vadim]

Thank you and thank you again for continuing to bring knowledge to the masses for free!!!❤🎉❤🎉

[@alec_almartson]

I'm really really surprised. ❤ Thank You Code Monkey for democratizing this knowledge.

[@dreamisover9813]

Amazing! Your older videos way back when dots was quite new were really helpful as well

[@lamhoang-vt2ih]

Thank you so much, I have been waiting for this for a long time!♥♥♥♥

[@MochiRosu]

Code Monkey You absolute legend. Thank you for this.

[@therealrevelen]

Thank you so much Hugo. Did the whole thing and learned a ton about DOTS syntax and usage. Doing great work for the Gamedev community!

[@CodeMonkeyUnity]

Nice! Congrats on completing the course! I'm glad you learned a lot!

[@Digildon]

Thank you, right on time

[@LiamKarlMitchell]

Well good thing I did not have any plans this weekend other than trying to learn the dots haha. Thanks !

[@Adam-qq9zk]

Thank you so much! This is an excellent lesson on the game, exactly what I’ve been hoping for. Your lesson covers almost everything I wanted to know.

[@CodeMonkeyUnity]

I'm glad you're learning a lot! Best of luck with your games!

[@marveII0us]

Thanks a lot Hugo! Your effort into making this (and many other courses) is insane, and that too giving the courses to us for free is incredible. I'm going to like, comment and share with multiple accounts of mine to try and help with the algo (Though its much more complex than that with retention, ctr etc...)

[@CSPlayerDamon]

Awesome! Thanks a lot mate, I needed a tutorial on this to avoid reading the docs and most importantly trying and failing :P

[@pedropc5824]

The man is unstoppable👏👏

[@TheCookingPixel]

Thanks for this course, DOTS is a complex subject, but you are teaching it throughout making a complete game, thanks.

[@urirat3750]

WTF 1 MONTH AGO? 7 HOURS FREE COURSE? bro... idk if the course will be good or not but, that's a lot of work. You are amazing...

[@CodeMonkeyUnity]

I hope you learn a lot!

[@Suhail-d9r]

This course looks like an absolute blast. Can't wait to get into it. The one thing I'd love to know about is skins. Eg if I want to have the option of my soldiers wearing a red beret or a blue beret, or change the hat to a traffic cone, how would one make those changes?

[@هاشماكرمعيادي]

Fainally the vedio which I have wited so long from the goat

[@yeeeetsssusdelets]

hope the rest will be uploaded too :D either way thanks for this huge video, went through everything and helped me a lot

[@NeoNthriller]

Thanks can't wait to watch in full

[@inversebrah]

great tutorial man, so much attention to detail. wonderful

[@CodeMonkeyUnity]

I'm glad you're enjoying it! Thanks!

[@greenheart5334]

Glad Unity is on good way again btw. I don't use it but some of my fav games run on it. When we at it, I make roguelike, initial version is already on NG and Itch. I will do my best.

[@mikithekynd]

it's here!

[@sannanch7564]

Thanks alot code monkey..... brother i can't thank you enough so greatful to have you as my mentor Again thanks

[@Wonder_Verse_Tech]

Finally My Dream Tutorial Came 🎉♥️🗿Thank you so much Code Monkey

[@schouffy]

Just wow, releasing this for free is unbelievable.

[@CodeMonkeyUnity]

I hope you learn a lot!

[@aL3891_]

Bruh you released the whole thing for free? Legend..

[@DutchyChannel]

The way you have to be specific with queries to get the entities you want reminds me a bit of SQL.

[@rootbindev]

Tack!

[@CodeMonkeyUnity]

Many thanks for the super thanks! I hope you learn a lot!

[@mohamadbakr6474]

Thanks very much

[@canerkaska8355]

Great job as always Hugo! However, I have a question to ask. I'm fairly new at game dev and have barely learned the basics on the GO-oriented side (mostly thanks to your videos). What I wonder is, is it a little bit too early to learn DOTS? I mean not for me, in general assuming there'll be a lot of changes and most things you show/teach in the video will be obsolete.

[@gamedebix]

Hey code monkey you are a true boon to game industry ❤️

[@trantuananh421]

Appreciate your contribution so much!

[@sokoku5569]

Thank you for making so many soooooo good free Courses and on top of that even more good videos with nice topics (also GameDev Report is so nice Thank you for that too) i sometime think writing stuff like that dosn´t matter but this time i am just too grateful not to write something. Thank you! ❤

[@lawowthebigboss9607]

Code Monkey is the best teacher

[@mohamadbakr6474]

Thanks for you efforts. A question is there going to be another course for netcode for entities. Since I cannot find much resources. And if you are going to make one, is it going to be any time soon? Thanks

[@Taher_M]

Thank you so much sir

[@danixadem]

That's awesome !! THANKS A LOT !!!

[@vincentlim8364]

Wonderful course!

[@Magma-uw7yo]

I'm not a complete beginner but honnestly for me I do games for fun to play with my friends and it took me already a lot of time to understand the logic to have for making a game. It's very interesting but I don't think I will change my process because it mean to add a new kind of logics on my brain and that's too hard for the games I make. I keep watching and maye for one project I'll use that just to try

[@CodeMonkeyUnity]

Yup keep DOTS as just another tool in your toolbelt, use it for specific use cases (like pathfinding, complex AI) and keep Game Objects for the rest.

[@Veles017]

It's amazing!!! Thank you!!

[@jihadrouani5525]

Thanks for this super useful video, commenting for the algorithm 📈📈

[@duztine]

Thanks a lot, you're a legend

[@theashbot4097]

This is awesome! I have YT premium, and I am watching the video at .25x speed, and the speeding it up to 15x speed using a web browser extension. I hope this helps with the algorithm. I also have YT premium, and I downloaded the video, and try to brake the algorithm in that way too. : D Thank you for making this free! I will buy the paid one soon!

[@AtomicDurpYT]

I'm not sure if you do fix this. However, if you single select a unit without the selected component such as the zombie, it will throw an argument exception. BTW, your courses are the best I have ever followed 👍. Edit: Never mind, it got fixed, nice.

[@CodeMonkeyUnity]

Yup fixed st some point, I hope you're learning a lot!

[@AtomicDurpYT]

Quick question, why do you sometimes use SystemAPI.GetComponent, and other times use SystemAPI.GetComponentRW? my understanding is reference vs value

[@季捷-d2j]

I can't believe this is a free course, that's crazy my friend! Will you be bringing the full course to udemy?

[@CodeMonkeyUnity]

I hope you learn a lot! Sadly Udemy has some very restrictive rules that prevent me from putting my courses on there. Now I'm trying to make sure all my courses have a substantial free version of some sort. For example my C# course has the video lectures completely free, the premium version has a bunch of extra bonuses. For the DOTS course there's a free sample with the first third of the course, on Udemy that is not allowed. You cannot have a paid course that has a free version available that is more than 2 hours long. Udemy also has very strict pricing rules, all courses must be $20 which makes it impossible to do more niche courses like the DOTS course. And Udemy has a pretty terrible deal for course creators where if someone buys a course without being through my direct link I only keep about 20%. Meaning when someone buys one of my courses on Udemy for $20 I end up keeping just $1 to $4.

[@季捷-d2j]

@@CodeMonkeyUnity Oh my god, it's so bad, I'm on your side my friend! Another question, Unity has just announced in its roadmap that it will implement ECS for all in the next generation, will this bring huge changes for dots?

[@DarshanRanpariya]

First of all, Thank you very much for the tutorial a huge appreciation. I just wanted to ask you to set that runtime mode in entity settings that moves the sphere in scene view but it's collider does not move. Time Stamp 1:12:30 Can you explain that?

[@CodeMonkeyUnity]

Yup that's just the visual of the Gizmo, it stays showing the authoring state even if you set it to runtime mode. I don't know if they consider it a bug or working as intended, but the collider itself is moving, it's just not visible in the gizmo

[@jagdishsahu3935]

Thank you so much!!! 🙏

[@BlackAmongus-r9m]

Great tutorial, very complete and a good starting point to use dots. But I have a question does anyone knows if on unity 6 dots is fully supported on the web? Everything I found googling is outdated and it's basically says it don't have support and isn't on the roadmap, as a possible future dots user I would like to know the web support before deep diving in to it.

[@jonawottjwt5135]

TYSM

[@lcd11001]

Thank you so much🎉❤

[@DarshanRanpariya]

Thank you so much for you last 2 replies. I apologize for my questions, but I tend to inquire whenever I encounter confusion or need clarification, even if I understand that a particular method is superior. Could you please explain why it is not advisable to combine HealthAuthoring and HealthBarAuthoring? Is there a specific reason we cannot check for null references in such a scenario?

[@CodeMonkeyUnity]

Those are very different components, one handles the logic for Health and the other handles a Visual, you should always decouple your visuals from your logic as much as possible to keep your code nice and organized. You could definitely merge them, but then you are enforcing a rule that everything that has Health HAS to have a HealthBar when you might not want that, you might want something that has a Health component without a visible health bar.

[@muuubiee]

Neat tutorial, though maybe the jobs were a bit under utilized (but one example). What kind of things should you read up about, if you can't afford the course, to implement fog of war for example? Or if there's some other really big and important feature that's missing from the free course. I'll probably go and do Turbos dots tutorial now too. (Never finished the kitchen chaos tutorial, too little interest in non-dots, Java made me hate OOP)

[@Void-vn2vf]

Thanks !

[@DarshanRanpariya]

Please let me know why can't we use inverted isSelected on the unit selection? Time stemp 4:12:26

[@CodeMonkeyUnity]

Not sure what you mean, isSelected is the current state which is always true or false, the events are only triggered for one frame when that state changes, they have different purposes.

[@sol1dBl3ck]

Wow, this is so cool

[@KelasMalamVid]

03:04:37 you said that sprite is not supported by DOTS. I'm planning on making a 2D game like vampire survivor. Is a 2D game not supported on DOTS? how to check if something is supported on DOTS or not?

[@CodeMonkeyUnity]

SpriteRenderer is not supported, but you can absolutely just use a 3D Quad Mesh and a MeshRenderer. That's basically what the SpriteRenderer does on the background, you just need to handle that yourself. And 2D physics isn't supported, but you can use 3D physics and just lock it to XY To check if it's supported just add a component to a game object inside a subscene, either it will convert into native DOTS components which means it's supported, or it will not convert or do anything which means unsupported, or it will create a Companion Component which means unsupported and is basically using a game object

[@KelasMalamVid]

@CodeMonkeyUnity thank you very much. it is really interesting.. never thought it could be done that way

[@Suhail-d9r]

2:38:55 FINALLY encountered an error I am not sure how to fix!! On line 38, UnitMoverJob is underlined in green (Warnning): There is no defined ordering between fields in multiple declarations of partial struct UnitMoverJob; To specify an ordering, all imstance fields must be in the same declararion. he code still runs perfectlythough. I'm not sure how much of an issue this is.

[@CodeMonkeyUnity]

Hmm I've never seen that one, maybe you wrote some field name that perfectly matches some other field name in the auto-generated code? If it's just a warning and not an error then technically it shouldn't break anything

[@Suhail-d9r]

@CodeMonkeyUnity I've been using the same field names as you to avoid confusion. I'll double check the code and I'll update you

[@nmn5701]

Hey codemonkey, i am thinking of buying this course very soon now, i was wondering if we will get any discounts on it? for example the upcoming christmas or new year?? it will help me a lot... as 100$ is a lot of money specially from a third world country

[@parthpandya008]

Hello, I have completed 80% of the course, except for UnitMover, I was wondering why the Job hasn't been used for other systems, such as FindTarget, BulletMover, ShootAttack, and ZombieSpawner, which also handle more intensive operations?

[@CodeMonkeyUnity]

No specific reason to not do it, I just haven't gotten around to it by that point. During the polish lecture I do refactor a bunch of systems into jobs. If you have time then yup you should likely go ahead and convert almost every system into a job.

[@iiropeltonen]

04:35:00 Why can't we cache the Physics Singleton and instead get it each frame?

[@CodeMonkeyUnity]

DOTS is all about Structs and not Classes, since Structs are value types you get a copy of the data rather than a reference to the original data. So in general you can't cache things in DOTS, you need to grab it every frame, if you do cache it you usually get an error saying the data is out of date.

[@iiropeltonen]

@CodeMonkeyUnity Right, so the Singleton is also a struct.

[@suicune2001]

Thank you!!!!

[@MathsPlusGames]

I would have gladly paid 100$ for this
