In this video I go over the past few months of me tinkering on a Minecraft clone. I have added many different things to this clone. Some of the things I have added include: dynamic block creation, world saving/loading, OpenGL AZDO, order independent transparency, physics, 3D player controllers, commands, cubemaps, lighting, and more. I hope you enjoy my overview of how I went about recreating an iconic game, and I hope you'll join me as I create more videos diving deep on specific game mechanics in the future!

You need simple block based ambient occlusion and different lighting per surface normal. That should help the classic Minecraft look.

True
SMOOTH LIGHTING IS THE SECRET BRUH FR
@@TheTinyCreeperGaming RECREATED not cloned.
7:20 that seems to be the way minecraft actually does it. In the debug screen it has separate values for sky light and block light.
Not only that, but back in the day Minecraft also did it the naive way! It used to have to update every chunk on screen to perform the day/night transition. This caused a very visually noticeable ripple as chunks in your field of view updated, and sometimes even caused a bug where far away low priority chunks would still have daylight light levels during the night. Not to mention the hitch caused by having to recalculate all of the lighting in all visible chunks tens of times during the transition. They fixed this during the Alpha or Beta, by implementing the separate block and sky light levels, allowing the visual daylight of chunks to be changed in real time with no recalculation of light levels.
@@newe6000 Yep! Good old days where you could see the whole world break up into square chunks as they all tried to update and get darker. I believe this was changed in the pre-release of Beta 1.8, which also prettified the game in some other ways. And it allowed for colored light too! So the sunsets turned orange.
Pretty sure he knows this as he explains the system in a Minecraft video from a year ago lol
How do you not have hundreds of thousands of subscribers already? I didn't glance at your sub count before I watched this video, but the quality is insane for such a small channel. Good job dude, seriously
Thanks Night Shade! It's always great to see such encouraging comments like this :D
@@GamesWithGabe do you like monke?
Thank you for teaching modern noise! Even as only a brief mention of what you used, it really does help the field move forward.
The section on pinned graphics memory was enlightening too, and I'm definitely going to look into how that may apply to the current projects I'm contributing to.
Wooohooooo! Been waiting a while for this one, I wasn't able to join too many streams because of timing so this will be fun to see how you did it.
Wait you're here too?
@@CarlossInsurance hey carlos lol
hopson gang
When i see a game developer making anything without an engine, i see him as a god, good job on the quality of the vid too, you are getting places
I've been struggling to write a 3d renderer in OpenGL for weeks, this is going to be so helpful to pick apart and learn from!
You are seriously underrated. And I truly mean that. You're unique, your dedication to your content shows, you care about your viewers' time and their interests, I can tell you're not here for views or popularity. Keep doing what you love doing and don't *ever* let anyone tell you otherwise
dude, i love seeing stuff like this, keep up the great work!
This is so cool!
Maybe, as this little project progresses, you'll eventually be able to make it into a game of its own, not just a recreation of Minecraft.
I love Minecraft clones. I have watched almost every voxel engine demo on TH-cam. I love to see what people choose to implement and how. It's akin to song covers.
Subbed. I love that you touched on multithreading, you touched on benefits of c++ to manipulate low level... You sparked interest that drives me to learn other things. This is what I like in my subbed stuff.
That's so much work man! Amazing!
I'm looking forward for the LWJGL 3D tutorials, you do such an amazing job with the quality of your videos!
Awesome work, Gabe. I’ve been replicating the code from your java 2d game engine series in C++ and this can only make me more excited! Something I would recommend is that if you’re using the official minecraft textures/fonts you should replace them with something else so that you don’t get into legal issues. If you’re already using your own assets just disregard what I just said.
Awesome Video bro! I have been looking for good tutorials in this area for some time. I would be very happy if you continued to make videos about the project
This channel is a gem. Keep working on it!!!
Awesome video! I am really happy that your channel finally blew up!
It's amazing man, good job. But I have to say that the only thing I care about when I see clone projects of MC is how much better is the performance and if it's even better. Because the ultimate dream is to essentially create a minecraft with a pixel sized voxel, but that's just too computationally intensive.
never seen your channel before, but this video definitely earns a subscription. impressive work!
This is pretty good! Hoping to do this myself one of these days, once I'm more comfortable with coding.
Very interesting video! It was incredibly well edited based on your channel size. I wouldn't be surprised if more of your videos blow up in the future.
Amazing editing. All those animations don't go unnoticed. Nice work!
Thanks Foursy! And I'm glad you liked the animations, they did take a big chunk of time :D
I'm a web developer but these videos are just so interesting and entertaining for me. Keep it up!
I really love the lighting system of the game because it looks like real minecraft!
This copy game is really well made, and you can actually explain stuff very well, and i can actually understand what you are saying without any coding experience! Extremely underrated
Wowww..Looks awesome!👏👏👏 Have to learn this from you! Waiting for your minecraft making tutorials! 😇
Another amazing video, rly hope your channel blows up soon
Amazing video with great quality. I've never heard of this channel before, and just 1h after its uploaded its in my recommended for some reason, and probably in others aswell. You're gonna blow up, and you deserve it, keep this amazing quality up, and you gonna get big quick
I would love to see some updates on this clone. it sounds really cool
Enjoyed the video, thanks!
Watching you add all the code and make the game and then I seen the end result it brought back wonderful memories when Minecraft first came out😍😂
Could you do a very specific tutorial on how the lighting works, like with code examples? I am making my own voxel engine and would like to understand this better. Thanks for the video! :)
this is a good ass video man! keep it up you'll get there
Looks great so far! Sucks I've not been able to catch the streams
YEAH GAMERS.
He did just drop a new Minecraft.
🔥
Seriously though walking someone through this with unity would be great. Even just a code walk-through explanation should be quite valuable to me, whose literally just made 2d shooters and 3d controllable spheres.
channel got blessed by the youtube algorithm congrats man
MY GOD IVE WANTED SOMEONE TO DO THIS FOR AGES MAN
Wow, very interesting vid, you earned my sub
This video is going to blow up for sure
I'm looking forward for the tutorials! I want to make a minecraft inspired game, so it'd be a huge help :)
OMG THIS IS THE TRUE MINECRAFT CLONE I WAS LOOKING FOR
More videos about this would be cool :D
Great work hope this gets more views!
Awesome video. Great fan of Minecraft and programming, I'll be back :)
Awesome work
Another great find
Great video! I got the game working on linux through wine.
Just Awesome!!
Great game! You should add more to it!
8:12 [shows working transparency]
That's actually pretty advanced. Why didn't you talk about it in the video?
Working on my own minecraft clone, that's one of the harder problems I have.
How did you do it?
Is it resorted every frame and reuploaded to the gpu? (If yes: Isn't that like super slow?)
Or do you do fancier stuff like using instanced rendering for transparent blocks, to avoid uploading the chunk meshes again and again?
Or is it maybe even done in the shader using depth peeling?
Or are you just lazy and use a commutative blend function?
He loosely goes over this same struggle in his original video, as this is a continuation video of his "Minecraft in 2 days" Project.
I actually got confused, mixing him up with another youtuber. This video covers transparency as a challenge, if you're interested th-cam.com/video/4O0_-1NaWnY/w-d-xo.html
Hey Quantum Developer! I was thinking about going in depth about the transparency, but I plan on doing a whole series where I do a deep dive on each of these issues, and this will be something I'll cover in that series. But, I tried really hard to be a lazy developer and it just didn't look good enough, so I had to go to a more advanced technique.
I tried resorting every frame, and that's not as bad of a performance hit because the way I submit the draw calls to OpenGL is using the glMultiDraw*Indirect function, which means I can just resort the draw calls and resubmit a small command buffer to OpenGL and that will resort the order that you draw the geometry in. Unfortunately, resorting the geometry every frame doesn't work for *everything* because if you have two glass blocks in the same chunk that have been meshed together they'll break unless you sort based on the fragment position.
I eventually found some really good articles about Order Independent Transparency, and that's the route I took. Once I got it working right, you don't even have to reorder transparent geometry and it still looks correct. You do have to separate solid geometry from "blendable" geometry though when you draw everything, otherwise it won't look correct. I followed this tutorial to implement OIT: learnopengl.com/Guest-Articles/2020/OIT/Weighted-Blended
Best of luck with your clone as well! :)
@@GamesWithGabe Wow, that's a clever algorithm. I like how they faked the overlap using a z-dependant weight.
Sadly it doesn't work for me though :(
I am using volumetric fog, and that requires knowing the distance between the front and the back face of a volume.
Although I might have an idea how I can adapt it for that as well...
@@GamesWithGabe lazy? ya mean efficient 👀
Yikes
I just realised mid way that this video only has 500 views...
I was really sure it must be one of those 450k views or something... Keep up the great work ;)
SO UNDERRATED LEGEND!!
Wow, very well done, super cool.
fell in love with a new youtube channel
I'd love to see you develop this further into its own game. Minecraft has had the monopoly on voxel sandbox games for way too long, and I think because of how far removed modern Minecraft is from beta Minecraft, there's a nice audience waiting for that kind of classic Minecraft feeling.
You should take advantage of Mojang/Microsoft self-sabotaging their own game while you can.
Beautifully executed.
Finally someone is going further with the idea of a Minecraft clone. One of the things that'll really make this one stand out from the rest is the addition of ambient occlusion on the blocks. If you manage to add it, there will be a very noticeable improvement to the visuals of the game.
Thanks for the comment unyxium! And yea ambient occlusion is on my TODO list, I've just been lazy and have been implementing more "fun" features haha
Great video Gabe, some amazing work you've done here!
Now remake the unviverse :p
As a person learning frontend for a long time. And now learning java for about 3 weeks. This still looks like a magic to me.
A better way of implementing lighting is to not modify skylight on night time, but instead of a factor (mineraft calls "internal skylight") that gets modified during night time as an uniform and that will be multiplied to the skylight in the vertex shader. That way the day-night transition will look smoother, and prevents costly light updates.
Love your videos
Cool stuff!

EXTREMLY NICE VIDEO!!! BUT: pls show sometimes more of the process, for example when u are creating the hotbar or so
Holy shit that's awesome!
This is soooo impressive
Holy hell this is impressive, as a comp sci student at university I understood...1/2 of it lol
Hitting that bell for when he uploads updates
Great stuff, wouldn't have thought that multi threading reduces the RAM requirements of chunk loading... But I guess it makes sense *hmmm
Wow that's cool to see
This video is bussin!
This video is great!
I also made minecraft kind of clone. Most people just generate some small voxel, do simple collision and add block placement/removal. HOWEVER.. when you start moving past the basic features you really start to understand the complexity.. and also possibly inflict yourself with a slight obession about all these topics. It's a roller coaster of frustration and joy. "Infinite world" with chunk loading/unloading, transparency, all kinds of optimizations, chunk generation, chunk/patch poly reduction... and that's only scratching the surface.
I absolutely 100% agree. So many people dismiss the amount of effort for seemingly small games. Heck, building a full NES Super Mario clone is a solid month of work at least. I really appreciate it when people realize the amount of work and dedication that goes into a game :)
This is insane... I want to do that too, just to learn coding
Woww I only just saw your way too low sub count after watching the video. Amazing quality!
I'm only a few minutes into the video so maybe this is brought up later, but a large texture atlas is actually how the real Minecraft used to store it's textures, you probably knew this if you ever made a texture pack for old versions of the game. Nowadays the textures are all individual images, except they're not. Minecraft actually stitches all the images together into a texture atlas at startup, even in the latest version.
Well done! And good video editing :)
You mentioned this article about the lighting. Would you mind sharing it? Working on a Minecraft clone myself using direct3d and c#.
Hording tons of Minecraft related information :D
Thanks Felix! And yea I probably should have included that article, but I just updated the description with the links :D. Good luck with your clone also!
I want that texture atlas as a quilt!
You have single handedly and wholly made me motivated to start programming again. I used to program in C/C++ and Python a bunch, but I stopped because of extreme stress and stuff. I think I forgot how much I enjoyed it. Thank you so much.
woah EPIC!
never imagined creating minecraft was that huge of an achievement
I cant wait for people to start speedrunning this
Manim looks great!
can't wait for when you try the greedy mesh algorithm haha
Smooth lighting would make it kook like modern Minecraft
Awesome video with concise explanations, I need to take some notes! Quick question, did you use 3b1b's manim library for the animations?
Thanks! And I did use 3b1b's community manim library :)
@@noname_hacke_9747 why are you commenting so much
This clone is the most Original minecraft like.. among all other minecraft clones out there
It'll look really cool with more biomes! (if you haven't done it yet)
WAY TO GO FOR 10K SUBSCRIBERS!
I think an FOV slider should be added soon because it looks a bit zoomed in most of the time in the video
I'm so happy to see an in depth clone like this. I was curious for your lighting, you said you take your highest value around a block and subtract 1. How does this work? Like this makes sense till I think that I'm iterating through and start with 15 the the next block goes 14 then 13..... like what am I not understanding to prevent it from decrementing in the open where the value should all be 15/14. Thanks.
Hey thanks for the comment! And the algorithm is a bit different when it's skylight. Skylight is considered any block that has no blocks between it and the max y level. If a block is skylight then it just takes the max light level and as night time comes along it subtracts the night time values. Then when it hits a non-skylight block, it does the flood fill algorithm that you were explaining :)
@GamesWithGabe Ah that makes total sense thank you so much for the explanation.
Fire 🔥
Waiting for the tutorials on how to do it
Thanks! I'm hoping to release the first video in 2-3 weeks :)
@@noname_hacke_9747 watch the video….he’s very clear that he will

Haha you are a legend my man.
Omg, this is so cool
Only in months. God damnit. That just show how tough Minecraft is
I think you're the first person who picked up on this lol. Everyone else thinks I'm saying it was easy to recreate Minecraft XD
