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!

@newe6000 2 жыл бұрын

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.

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?

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! :)

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.

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.

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.

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.

Maybe there is less overhead but the time you would have saved writing a lot of this (and a lot of what you'll have to write in the future) seems worth it.

@GamesWithGabe 2 жыл бұрын

I've done this before with unity and unreal, and you do save some time, but you run into technical limitations pretty quickly. You end up with a lot of problems with lighting and stuff as well since unity and unreal are expecting normal geometry, and not meshed chunk data. To fix that you end up redoing a lot of the stuff I did here anyways, so you end up still spending the time on the same tasks :). I also don't like the way the physics feels with those engines, and it's a lot easier just to roll your own physics for a game like minecraft, and I think it's fun using OpenGL :D Also I would definitely recommend giving it a shot, you'll learn a lot!

There is a game called CyubeVR which is like minecraft in VR and the developer of that still has some of these issues you described despite it being like a 4 or 5 year long project. And I know he's doing it in Unreal. How do you plan on handling multiplayer? I surely hope you aren't going to have to make a networking framework yourself haha.

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.

@GamesWithGabe Жыл бұрын

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 :)
