3 Months of Game Programming in 20 Minutes 

Your technical knowledge is amazing, I'm always impressed with how much you manage to do and how you do it. I can't believe that you added raytracing aswell.

I would strongly suggest watching some better videos for inspiration (seriously though, incredibly impressive to see such an engaging explanation of something that may as well be magic as far as I'm concerned!)

I don't think it devalues the idea at all, but the "robot cultivating plants" pitch instantly reminded me of Grow Home & Grow Up. Very different though as the main focus of those games was unique (for the time) movement & climbing mechanics in 3d environments. Potentially some good research opportunities there!

Seeing vec4 in your code and the projections reminded me so heavily of my computer graphics class. You NAILED this. Great work! Keep it up, ill be watching everything you put out

Dude, that looks really awesome! When I first saw those portals with the sick a$$ lighting, the bloom and the glowing particles _in pretty much all colors of the rainbow_ my jaw just about hit the floor! It looks really, _really,_ *really* good! I'm looking forward to playing your game already 😊

I would love to learn more about your NeoVim configuration, it seems that your workflow is really robust in it.

Man, that's crazy! I love the style and how much you went through to get to something you were happy with :] I was surprised to see someone come up with an idea so similar to mine, (and actually start making the game lol) really hoping it comes out fully fleshed out someday! We need more robot vs nature games out there haha

I find it super satisfying when a pixel art style game actually has consistent pixel size so epic work doing that as well as implementing things that wouldn't traditionally be seen in such a style like smooth camera interpolation

how consistent were you in these 3 months? Did you have lots of breaks in between or were you grinding the whole time?

Amazing video! Recently I've gotten into game development (although I'm starting off with Unity and C#, I doubt I could handle the mental strain of making anything remotely playable in C++ my first try haha), and videos like these are what really pushed me to start in the first place! I'm probably about to use the wrong terminology, but there's just something so fascinating and inspiring about seeing how iterative the design process is; it takes months of dedicated work to achieve systems that most players will take for granted, and watching how you find solutions to functional camera and lighting systems makes it seem a lot less daunting! I was introduced to this channel through the Minecraft from scratch video and found this video through your tweet -- and I'm looking forward to seeing more progress on this game's development!

LES GO WE GOD MORE JDH! Love watching this stuff, been around since the beginning and cant wait to see more!

Very cool project ! Do you think you'll make the repo public someday ? I'd love to check out that engine

Awesome video! I really like how this game is turning out, and i'm excited about what you do next.

your videos are epic. they are super entertaining and I love how you explain everything. honestly one of my favorite youtube channels.

As always, an amazing and VERY inspiring video!! Also, maybe you can consider adding a "pinch of" factario by adding some mechanisms that help you to reach your goal.

I’m absolutely in love with all of these concepts all together. I love the setting, the art, the whole idea of it being underground, the building, all of it. I really hope we’ll get a playable version soon at some point.

The voxel jitter fix reminds me of a technique used in (directional light) shadow mapping to essentially correct for the same problem there: as the directional light view frustum moves with the player camera, object rasterization to the shadow map produces aliasing artifacts which vary with the camera view, so shadow edges flicker and warble as you pan the camera around or move. In that situation you define a matrix projecting the center of the camera frustum to texel space, floor its x/y components, and project that back to world space before finally using the floor()'d frustum center position to produce the actual light view matrix. (I was not smart enough to figure this out on my own, and had to study the trick before properly understanding it, but you're clearly a different breed)

i'll be honest, the screen when palletization is off also looks really cool. the vibe gives me sort of a deep game with soft, subtle graphics that might show the way someone sees the world. i really hope that there's gonna be an option to be able to see the game without palletization, even if the graphics will be made around the idea there will be palletization, it looks like something that would change the graphics in such a subtle but impacting way

This is very impressive, I'm enjoying these dev logs. It would be cool if you could make a video going into more detail about the coding aspects and how you overcame some obstacles. Other than that, it's looking really good :D

Great to see you flesh this out. It's really interesting seeing the problems you ran into with 3D isometric rendering.

This is the first time I'm actually watching one of our movies and at ~0:40 I already subscribed. I love your setup and it's what I also use. But probably the reason I subscribed has more to do with the fact that I relate to your struggles while game designing / programming. I wish you luck and hope to see great games from you! ;)

This is incredible! genuinely! I can't believe you did this, I can barely work with angles in my games, much less lighting effects, ray tracing, I can barely make a working camera. I'm in a similar boat because I use python and pygame to make games, but there is still a lot of stuff under the hood that's already done for me, so this is just genuinely baffling to see!

'Turns out game design is harder than any programming problem.' *(as a programmer)truer words have never been spoken

I'm getting into programming, and development. I love watching what others are doing. Thank you!

Hell yeah, new jdh video just dropped

Keep up the great work jdh, you are inspiring me to get more done especially my programming language

Being a guy who has just started out with programming & CS in general, this all is not only overwhelming but also excessively intriguing. I have always loved the idea of lines & lines of text making a machine do what you want it to. Great video! I enjoyed the dev log very much!

I'm really looking forward to see how this project will turn out, you are one very dedicated programmer, wish u the best of luck

I love your videos, each one is inspiring me to continue working on my projects or learn some new tech!

I really like your C++ coding style. I think you use the modern luxuries of the language whilst still keeping it readable and treating it as a C with Classes.

been working on my own game/engine for a few months and this is really inspiring thank you

great work! looking forward to working with artists like you on the second renaissance

You are so incredibly talented! I love video games. I especially love programmers that create something new, to me it shows wanting more than just programming but art and innovation. Keep up the awesome work, I am always in awe at how complicated games are, and truly respect when one is dont well.

This looks really cool, excited to see more! I think it's a bit jarring when the camera changes angles, though. Have you tried adding a sort of rotation/transition animation when rotating the camera around?

That smooth camera movement is amazing. I saw that other video too by aartheficial, amazing stuff.

Finally, a new video, love your content! 💪💙

Awesome !! Very interesting work. Big up

Watching you navigate you code with your neovim workflow is incredibly satisfying for some reason Also I love the games name!

Amazing work!! Jdh is a Very talented programmer and computer scientist, hats off!

Respectfully i NEEEED more! Chill vibes and I really like the aesthetic of your game, keep it up (or else)

That looks fantastic! I'm excited to play it.

This looks so good dude! I wonder what might be lurking in the underground that could hinder the robotanists flower finding progress

heeey a video from you, nice, can't wait to watch that (edit : very nice video, i learned quite a lot of things while watching it that will most likely be useful for me in some years, yay)

Very tasteful design, the lighting is fantastic

The game is looking fantastic, I really like the concept and the name!

Am I the only one that find it so relaxing and mesmerizing just looking at all that code being written while listening to the soothing voice over telling about this amazing journey?

Great video can't wait for the next one!

Worth the wait mate! Keep up the work.

this is fucking nuts. looks absolutely stunning can’t wait for the next devlog

you deserve 1 million subs NOW!!!! ur the best programming youtuber I've seen!!! And also you inspired me to create my own game! So thanks for all.

This is really cool work, I always enjoy seeing how people encountering similar issues end up with their own unique and clever solutions. I was a dev on the now defunct game, Crucible, and we too had a character that was a plant loving robot. Its name was Bugg, but can you guess what its codename was? Yep "Robotanist." I'm sure we weren't the first to come up with that concept/name, but I'm pleased to see that we were on to something. :)

Cool lighting and cute graphics!!

It's cool to see everything coming along and the game design falling a little bit more into place. One detail I'm not too sure about is the palette stuff. I feel it makes the game look like a heavily compressed video and I personally prefer having smoother colours. Of course, I'm not suggesting you remove it necessarily, but if you release the game, an option to disable it would be much appreciated.

Don't strain yourself too much, every video you upload is a treat.

Really coming along, nice work!

Good video thank you , updated visual studio and everything worked. I'm really glad I found a work

I'm in love with the art style and general feel of the game already

I know this is early but I honestly think you're one of the smartest programmers out there, everything you've done so far literally looks so amazing dude.

3 months wait was worth it for this!

the concept is so very beautiful :)

Keep Working on this, I feel this has a huge future!

Holy Shit, this looks fucking awesome. Really hope it gets finished, not like 99.9% of other game devs with dev logs (*cough* Karlson from Dani *cough*)

Is there any chance you would make a video on the planning/ prep required/put in to make a project of this size? It would be really fascinating to see the methods you use to break this down and make it manageable

The soft camera touch was simply.... hmmm satisfying. It helps easing the motion sickness that usually happens with full locked camera.

I'm just impressed you coded it all in neovim

this looks absolutely insane! really cool stuff! what do you use for building? are you using cmake or makefiles or something else?

One potential problem I see is that losing the character behind the isometric stuff is very possible (say while digging a tunnel), so the geometry needs to be turned transparent/translucent at least partly so the player can see through it?

wow this is so cool! imagine a roguelike with this art style i feel super inspired!!

Let's go new video I'm excited!

the palettized lighting looks so lovely

Great video as always. I am finding it challenging to carve time out for my pet projects with a full-time job I just started. How much time were you able to work on this daily?

Thank you man for sharing this stuff

Those raytraced shadows are mmm _chef's kiss_

Pretty damn awesome dude, subbed

Anxiously waiting for the next video about this game

Very Exciting. Great work as always jdh. Did you create the art as well?

Is the color palette reduction a shader or done on the CPU? Very interested to know how that process works.

Your robot-underground-in-caves game idea gave me this really awesome image of a mixture of the anime Gurren Lagann and the game Grow Home

2 videos from jdh, christmas hit early

Let's Go! So excited!

This reminds me of making final fantasy and dragon warrior like games in pascal as a kid with 2 of my friends. We even wrote a bitmap art program, tailor made to our games. It made sprite and tile art sooooo much faster to make than using other dos art programs too. One nice feature is you could 4 way split screen and load in 3 sprites, then being able to copy sprite frame to 4 and it could even play the pictures as an animation. (Every non background element had 4 frames). We saved a lot of processing by making custom fonts for all the background tiles, so we could fake scrolling. The hardest part was composing PC speaker music, which in the battle procedure, we had to hand code, and basic bank switching to have 3 copies of the game, one with battle music, one overworld and a town song. Honestly, programming without libraries is sooooo freeing. I miss those days from decades ago.

Translation is the paradigm, the exemplar of all writing. It is translation that demonstrates most vividly the yearning for transformation that underlies every act involving speech, that supremely human gift.

Fantastic work!

18:15 when I noticed the cute little green blinking light on top of the robot botanist that made me really happy 😊

When you were talking about the shadows, the entire time I was thinking "raytracing, raytracing, raytracing" as a joke but then you actually did it and I was so happy. It looks awesome!

I JUST REWATCHED UR OTHER VIDEOS LETS GO

The background music really sounds like a Minecraft:Pigstep lo-fi remix to me... Love it (and the video too, keep it up!)

If the Bee Movie taught me anything, it's that flowers need pollinators. Also, that camera overscan trick was real slick, made all the difference!

I really think this color pallete lends itself way better to bright and lively scenes. You might want to merge it with another pallete for the dark underground environment.

You're basically a wizard to me, but I'm loving this so much! Great idea, too😁

You're Vim setup is really nice!

dope video dude you got my sub

Hi, this is turning out really nice. What font are you using?

Maybe the robots blinker could change based on how it feeling or on its health. I feel like it would be cool and add lots of visual feedback if the light were to change to red when getting towards low health and start to blink faster the lower it goes.

It's a joy to watch you program, H. Jon Benjamin

What do you think. How much faster would it be in Unity? Last time when i've used cpp with ogl was like 15 years ago.

I'm like watching your video, I understand what your talking about but i can't even think of how i would inplement that! Amazing!

Do you have a like a target minimum spec for running this game, or make the game and what runs it runs it

I think your game concept has a lot of promise. I a gameplay loop where you learn how different elements of your ecosystem interact through experimentation and use that knowledge to make it self-sustaining would be very fun.

Impressive work ❤
