I Made a Minecraft Clone in C++

[@wsalevan]

Hey guys! Thank you for watching the video. I know it's been a while. I'm going to try to upload at least one video a month from now on, but we'll see how it goes. Feel free to hold me accountable to that lol. Let me know if there's anything you'd like to see in future videos!

[@darkphinkwastaken3362]

bro said I'm not good at c++ then makes a Minecraft Clone. Good video you just earned a sub

[@wsalevan]

Thanks for the sub! Most of the code wasn't specific to C++. When I made that comment, I was specifically referring to my C++ knowledge and not my programming abilities as a whole. I struggled a lot with things like rendering and threads. I could see why it would sound like a humble brag in the video, though

I also jumped into the deep end and started learning 3D programming, C++ and OpenGL for the first time by making a minecraft clone and went through pretty much the exact same steps you did but hit a brick wall due to my lack of knowledge. Seeing a simple and easy to read working model (even if inefficient) like yours is going to make my learning so much easier! Thank you for sharing this project!

[@wsalevan]

I'm glad my project could help you!

[@Console.Log01]

I started my first c++ project a little over a year ago, and I'm still working on the same game (albeit I've restarted from scratch twice) and the improvement is massive. Keep going!

[@wsalevan]

Nice. C++ is a difficult but fun language. Thanks! Good luck on your game!

[@TheBcoolGuy]

You should try making a small project in just a few days, like Ludum Dare, so you'll have taken a project through all stages of production. It really helps.

[@dampfwatze]

It is actually very suboptimal to create a new thread for every chunk. Creating a thread has significant overhead. Your program has to reach out to the OS and the OS itself takes really long to create this thread. Instead, what you usually to is to create many threads at the start of the program (usually as many as you have CPU cores) and build some sort of task queue, from where the threads take tasks that need to be executed. This is called a threadpool and there are libraries out there. These tasks might also be referred to as "light threads" or similar. And having more threads running than the CPU has cores, leads to bad performance too. In this Situation, every core has to run multiple threads (with similar amount of work) at once, which leeds to excessive context switching. This means, the core has to switch the running thread every few cycles, which has major overhead.

[@wsalevan]

Thanks for the suggestion! I did come across threadpools in my research, but I had so much trouble implementing threads that I decided to hold off until a future video

[@vinhtiennguyen1292]

With this big magnitude for your first c++ project I can't imagine how many companies out there are trying to recruit you

[@wsalevan]

[@mariovelez578]

Directional diffuse lighting is easy to implement and will make it way easier to see blocks. Also, I made a (unfinished) Minecraft clone as my first C++ project and did it mostly how you did. Don’t worry about optimizations right away, just get things working, I feel like it’s better learning to make mistakes and then fixing them rather than worrying about all optimizations at the start. Also, if you think 140 lines of code is a lot for a triangle, just wait until you try Vulkan

[@wsalevan]

I'm definitely going to be playing with shaders in the next episode. Now that I look at it, the video is a bit hard to look at lol. I agree with you about the optimizations. I'm going to be slowly optimizing it over time instead of doing it all at once. I did a bunch of optimizations at the end because I was so close to 10 minutes of runtime and wanted to push it past that point. Vulkan sounds scary lol

[@multiarray2320]

[@porky1118]

A while ago I saw a video, where somebody optimized the performance for rendering in minecraft. Not sure where to find it, though. He got the rendering performance up by a factor of a million or something by taking advantage of the fact, that all faces only face in once direction and only the surface ones are shown.

[@Gregthecool800]

Looks a lot better than the Bedrock Edition of Minecraft.

[@Failed096]

"dude, i cant afford minecraft, lemme make my own"

[@wsalevan]

My exact thought process

[@MichaelPohoreski]

5:35 DEBUG builds typically have NO optimizations so real-time rendering will be extremely slow. In large codebases such as UE5 it isn’t uncommon to compile _most of the program with optimizations_ on and to _turn off optimizations for the few functions_ you need to debug.

[@wsalevan]

Yeah I definitely didn't explain myself very well in the video. I knew that debug builds don't have optimizations but I wasn't expecting that big of a difference. It's not shown very well in the video but the chunks take about a fifth of the time to generate when in a release build

[@MichaelPohoreski]

@@wsalevan It depends on the task but yup, while computers are extremely fast the overhead of no optimizations, debug information, exceptions, and type safety can add up _significantly._ On a few Wii games I worked on I built our graphics library with full optimizations and compiled the rest of the game with debug info. and no optimizations to make it easier to trace when it crashed. It is always fun to see the performance difference between no optimizations and -O2 or -O3.

[@wsalevan]

Wow that's crazy. Yeah I never would've thought that the optimizations would have quite that big of an effect

[@MichaelPohoreski]

@@wsalevan 😅 How and where did you learn making vertices to make 3d shapes. I have learned C++ from my university and they never told us about 3d shapes and GUI like stuff. I tried to find online but didn't understand anything. I have made apps in java with android studio and dart in flutter but they provide premade library. I want to create something custom like you have in this video. Can you tell me a little bit of road map. Do I really have to learn openGl with this as well? My skill level in C++ is.... In my last project I made a game which ran in cmd. It was a robot catching numbers. I used 2d array to create game area. And gave the game some colors using ANSI escape characters, Which control the color of text and it's background.

[@wsalevan]

To start making graphics, you need some sort of graphics library which is probably why they never taught you about it in university. I would recommend OpenGL to start with but there are others such as Vulkan and DirectX as well. If you want to use OpenGL, I would recommend following learnopengl.com.

[@porky1118]

I suggest not using OpenGL anymore, but WGPU. WGPU is a more modern rendering API written on top of the lower level Vulkan, originally supposed to be a more modern OpenGL for the web, but not as close to hardware as Vulkan, which would be difficult/impossible on the web. But it's just a modern rendering API, without the old features and closer to Vulkan. It especially doesn't use global variables internally, but instead relies on structs. Also it's cross platform and works on Apple, which doesn't support OpenGL anymore.

I learned C++ from learncpp.com. Though I already had a lot of programming experience when I started learning it. I actually started learning coding when I was 11 and I started with Scratch. If you want to start making games right off the bat, I would recommend learning something easier than C++ such as Scratch, Python and PyGame, or Unity/Godot/Unreal. If you learn an easier language, most of those skills will be easily transferrable to more difficult languages.
