Hi Cherno, is there a way to make a one time contribution to support your game engine project? (I don't want to do it on the membership basis)

[@TheCherno]

@@anchutkastierlitz You can pledge any amount on patreon.com/thecherno and then immediately cancel your pledge, that's how most people do one time contributions. :)

Hi cherno, I would like to thank you for complete game engine series for free, never seen a video like this on KZbin some are too complex and some lacks useful information. I am a self taught graphics programmer so I have faced little bit difficulty in learning game engine architecture. The books about game engine are too expensive and advance too, there's no one in our country who can teach game engine. Your game engine series is like a gem to me this can help me to build a complete working game engine thanks a lot for giving a time to make this video.

[@chriscruz429]

I can't believe how much more I learn from hid videos than what I've learned at school.

[@WeirdBrainGoo]

Schools don't usually teach you to develop game engines, unless it's a vocational school or something.

[@Dagrond]

Love this style. Not only did I see everything that needs to be done, but I more importantly know why.

[@EternalEvanesce]

i have no plans of coding a game engine nor do i want to make games. Here just to see how it is built! The depth is just keeping me hooked

[@veroxid]

I recommend after creating the engine project: save that as a project template; this way you won't have to do _all_ the setup for _every_ project, just the parts that changes from one project to the next _(like changing it from a DLL to a EXE)._

[@JoseRodriguez-rx4ck]

In visual studio community 2019 I cannot see the "Project Defaults" section to access the "Configuration Type" is it only available for the full version? Is there a workaround? thank you

[@MartinAndrovich]

Why "bin-int" and not "obj"?

[@Jaredbud]

Just now getting into the series. Love the depth that you've put into this. Been wanting to build a level editor in Unity to get something that fits my concept. This may be a better idea as I enjoy knowing how things work.

[@lexsheyn]

This trick with repository cloning saved my day, thank you.

[@frankjibe]

Cherno, I just wanna thank you for your videos. I'm learning so much through your channel.

[@kombuchamp]

I always added readme and license after pushing local repository to the github so there is no conflict, never thought of the way to avoid it you showed here!

[@XxxGuitarMadnessxxX]

I am absolutely excited that you put these videos out; thank you!!! I'm just now starting to code along with this series and I can't tell you how much I've learned from and enjoyed your other videos; especially as a new aspiring programmer. Thank you again and I hope to eventually catch up to your current-ish (I know the dev flow is ahead of these videos lol) video series code-alongs!

[@matt-g-recovers]

The coolest thing about this is, other than everything (and saying the word declspec out loud) is learning cool stuff at every turn. I day job as an Android Java/Kotlin engineer in the automotive industry near Motor City and I can almost guarantee the concepts here will apply to making me better at my job;) (There is sincerity here so many overlaps, so many solutions recast as other problems and solved in CS).

This is such a cool idea. Although it may not help much anymore two years after posting the video, i turned off addblock for all your videos, i'll give all of them a like and am subscribed. I really hope this series keeps going for a long time!

[@gigik64]

Great video dude, but really, use git init and then add a remote origin, that thing you did with the clone was quite twisted xD

[@7c7c7]

It's nice to learn the origin of the name of hazel. I heard about the engine before watching this video and I though it was a reference to the hazel eye color. Hazel eyes are those eyes with a changing color with the distance from the pupil and it fits the graphic challenges a game engine faces. Just though it's an interesting coincidence.

[@MsJavaWolf]

I am not really interested in game engines, I still like watching your videos, I just pick small stuff up here and there. The thing with deleting x86 is one such small thing, I have wasted some compilations because I had the wrong config selected which I don't support anyway. Also in general I think it's really cool to see someone build a real project. It really helps you to see the big picture of software engineering.

[@catorials444]

Took me hours cause I'm stupid, I actually made a "custom build system" in CMake, that functions almost exactly as what chemo said. The directory contains two CMake projects that each has a CMakelists.txt file in it. One is the Hazel/custom game engine that statically links with all OpenGL libs and outputs a dynamic link library in a lib folder in the root directory, and the other is the sandbox template project that adds the game engine as a subdirectory and links with it. The root directory contains another CMakeLists.txt file that controls the flow of the build system by adding subdirectories. All of these feel very very hacky to me and I'm no expert. If you want the sample code just reply and I'll be "glad" to share it to ya, though It's not the best it works fine I guess... cheers!

[@EnryuTheUnknown]

What a great series to watch and work with, i learned alot in this vid thx and great work.

[@casvanmarcel]

I don't mind longer videos. That way you get more done and not become handmade hero

[@gavinw77]

Handmade hero vids were 1 hour + 30 minutes QnA, recent HH vids are 3 hours. I don't understand your concern.

[@derstreber2]

The two projects differ in several ways. (there may be more differences, likely are, and with time even more will likely become apparent) 1. Handmade Hero is completely programmed on stream, no code is typed in unless the camera is rolling. Only exception being in the rare cases that the stream goes down, and the local recording stops or becomes corrupted. To the best of my knowledge, it has only happened a handful of times, and Handmade Hero is approaching 500 episodes. 2. One of the goals of Handmade Hero is to write everything from scratch, no libraries. Only exceptions, if you can call them an exceptions, is the win32 api for interfacing with windows, and openGL for rendering. Noting that in the latter case he has already written a software renderer that does not require openGL. Edit: If I remember correctly he also showed how to use the stb_font library for font rendering, just to show how to use a lib in your codebase, but at the moment the win32 api is handling fonts. If I understand correctly, TheChernoProject's project will not be adhering to such rules. This will come with it's own benefits and drawbacks. And that is totally fine. Handmade Hero is great for what it is doing, and I hope that this project is equally successful for what it aims to be doing. In either case, much respect to anyone who can maintain a weekly regiment of work on a side project, and in a relatively consistent manner showing off such work to the eyes of hundreds, possibly, thousands of potential critics, plus balancing that with a full time job and family life etc. I'm looking forward to what is to come. Good luck.

[@shaikantest7646]

"avoid spaces in paths" - it's good advices for native speakers, but in general case it's worth mention "avoid non-english letters as well" as it breaks even more tools than spaces and is quite a common problem

[@admercs]

I second the request for CMake, gcc or clang, and Linux

[@HermanWillems]

while using windows only libraries?

[@themenko]

Meson > CMake

[@npc6924]

Adam Erickson If you're good enough with coding, you can do it without a tutorial. For a start, you'll want to compile all the dll(so) code with -fPIC and -fvisibility=hidden, and where the Windows version uses `__declspec(dllexport) void Print();`, you'll want to use `void Print() __attribute__ ((visibility("default")))`. For dllimport, just using external seems to work for me, but I'm doing this in C so idk what results it would bring in c++. Should I release my code for the Linux/gcc version?

[@axeldahlberg7043]

@@npc6924 That would be great :)

[@dekinxxx]

You are remarkeble. Just wanted to let you know. Please keep teaching these

[@jamesmnguyen]

It's not super important but you can link static libraries into each other. So the game can only need one link.

[@jaredgray7872]

That's exactly how I spin up a local solution for a git repository I've just created. Always thought there has got to be a better way but it works and it's basically no effort

[@anup.deshmukh]

Wow i am super excited to learn so many things from you.

[@haggard262]

I respect highly the approach, and I’m sure your implementation being framework centric was very successful. I’m looking forward to a non render foundational approach

[@Conversion108]

TRIED THIS 4 TIMES TODAY FINALLY WORKED!!!!!!!!!!!!

[@erin1569]

You probably want to define a macro _ENGINE_START namespace Engine {_ _ENGINE_END }_ and write classes like _ENGINE_START_ _class X : public Y { ... }_ _ENGINE_END_ instead of writing _namespace Engine { ... }_ manually It's done like this in the c++ string library and it helps you with indentation and it clearly marks the end of the namespace so you won't get confused with the last _}_ if you'll decide to expand the engine with more namespaces, but it can confuse IntelliSense in some cases.

[@playermat8574]

This is so in-depth..! You did amazingly :)

[@Pedro_ZKS]

This is going to be EPIC

Duno if you know physics, but if you do not, it'd be nice to get one of your colleague to work with you on the physics part of this engine and upload it on his channel with explanation. There are not any more proper (advanced) videos about physics in games. There are some articles, but I have not seen any engine series/tutorial/videos with fully custom physics inside.

Hey, @TheChernoProject, Great video series, really enjoying. Can you answer a question please? At 18:35 when you're adding Hazel.lib as a reference to Sandbox. I 've linked them, but when I open the Property Pages for Sandbox, I don't see the option listed in the property sheet. I can add it as an additional option, but wondered why, and will it break my code later ?
