As a programmer, mainly databases, but programmer non the less, I always wondered how fps games are made. It's a wonderful tutorial and education. Thanks for sharing your hard work with the world! Greetings from Honduras!

Thank you for this! I've so far only been able to accomplish super simple projects. By having everything laid out so explicitly I am going through the motions of a more complex project and learning a lot as I go and building confidence. Thanks so much!

This is really like a dream come true tutorial. Keep making these awesome tutorials. You are helping thousands of developers who can now understand how 3d games are coded.

I love your compartmentalizations of your classes and methods. You’ve inspired me.

just one of the best tutorials i've ever seen ! Excellent works thank you so much !

This was awesome, love how the raycasting part is just 15 minutes. Really dissected the that part and now I finally understand every single thing about it!

First of all Thank you so much for all your hard work and dedication !!! Great job mannnn ! When I initially show the game, I thought its going to be highly difficult to understand, but you really made it look nice and worth trying. Path finder part was just awesome intro to the game. A good learner will not only learn coding part but also about managing modules and files properly, what an experience !!! Thank you again.

Aww man, this is so cool. First time I see something like that. Ive always wanted to actually see someone program like that. I kinda knew who it theoretically works, but watching it like that, with your explainations, just awesome. Thank you so much. I actually recently played Doom 1 again, so funny.

i got recommended this. your format is fantastic. i can tell that a lot of effort goes into these videos. kudos.

Can't believe how organized the code is, you're a beast!

A whole engine in the first 15 minutes, great job man and amazing code structure!

Thank you very much! I started programming a few months ago, I started in Python. I learned a lot from this video, I spent a whole day on it. I already had the math basics, so I wasn't scared of raycasting, pathfinding algorithms and projection. I even improved the game a little bit: added levels, enemy lifelines, the menu, even a map in the corner that can be switched on and off, with different coloured dots depending on the enemy type. I've also improved my object-oriented approach. I have improved in several areas, so thank you!

That's awesome! So glad to see cool games and tutorials coming with pygame library.

Amazing work :-) I appreciate the way your work is so well organized.

Wow, this is an impressive tutorial, nice stuff

So detailed yet brief, excellent work

holy code! That's fast pace, but it's incredibly smooth and clean. Awesome tutorial!

An hour is about max for my attention span when watching a programming video, and most tutorials end up being too slow for me to follow up on once I start. This one hit the sweet spot. I don't know much about pygame or game development in general, but pretty much all of the questions I had about it were answered-at some surface level at least-during the time it took to watch this. Really well done 👏

You are continously increasing the quality of your tutorials, this one is in my opinion the best and most interesting one. Congratulations and thank you for your great work!

I found this fascinating! As a competent programmer, but having never written games, this was awesome! Thanks for taking the time to make it and get the presentation super slick! 😁

Thank you! Fantastic tutorial and so well explained. I was never good at trig, but you've explained it well.

This is an amazing walk through, thank you for sinking so much time into this video.

Never seen anything like this before. Everything from the explanation of maths to the coding is spot on 😯😊

This is a great demonstration of gradually adding features and testing along the way. I find when scripting, I try to jump ahead to the end state of full functionality sometimes, causing me to encounter errors and get stuck in debugging. This video offers good insights into how to break up a complex set of interacting functions, attacking them individually and gradually integrating things together.

Sick video man, I always look forward to your next video

This is an amazingly detailed tutorial and explanation. Thank you so much for sharing your knowledge

As a beginner, I just copied the code myself, because I understand the math very well, but I can not program. With the very good structure and very good explanations, and because I repeated many parts of the tutorial over and over again, I learned a lot in the process. Thank you for the very much and hard work you put into these tutorials of high quality. For me, they are the first tutorials that I really understood and motivated me to continue.

It's awesome the scripting time and dedication to code all that. Sorprendente el tiempo dedicado a la codificación y el cuidado de tantos detalles así como lo bien ordenado del código en los distintos archivos creados. Solo de pensar en los programadores de id software (John Carmack, John Romero, etc.) se queda uno fascinado por tanto trabajo, sobretodo en ray casting, colisiones con las paredes, la elaboración de los mapas para los niveles y otros tantos detalles. Ahora que aparecio este video lo disfrute y aprendí cosas nuevas en programación. Buen trabajo y felicitaciones.

Great video! I've seen many of these ray-casting treatments, and have done a couple ones myself, this is one of the best and full treatments. That said, basically in almost all of them, one fish-eye lese effect is still left unadressed. There are actually 2 kinds of those in a typical ray-caster, for 2 different reasons - the second one is more slight, and also more subtle to spot where it comes from - which is the choise of using angle deltas to compute ray directions: In a rectilinear projection as the one used here, that choise makes the rays hitting the projection plane distributed along it non-uniformly, where they get more spread-out around the center and more clumped together closer to the right and left edges of the screen (where this second fish-eye lense effect becomes noticeable). The full fix for that is to instead step along the projection plane itself (in this case, a projection-line, as it's 2D ray-casting), at a constant step corresponding to a fixed width of the columns. Then, the ray direction are the vectors from the player's position to those points on the projection-line - but normalized.This ensures the distribution of the rays is uniform across the screen, removing that fish-eye lese effect.

Wow! It's amazing the power and simplicity of python. Thanks for the tutorial.

This video is one of the best tutorials I have ever seen. Perfect for a beginner who wants to learn the basics of raycasting. The mathematical explanations were really interesting. For my part it was my first experience in Python. Very easy to set up and run things quick with just VSCode. As I have a lot of experience in javascript and C#, the next step for me would be to explore the whole thing in the unity universe :). I also really like the idea to start from this project and build biggest maps (or even a tiny virtual world) with this pseudo-3d retro style.

So there are some things I'd improve: 9:13 in so far -Compute player movement without using two (slow) trig functions every frame the player moves (Update: checked the underlying C source code for pygame, it's using a sqrt() function, not any sort of optimized square root approximation, so it's likely the trig is faster.) -Use a clamping method to make the player's whole circle, not just its central point, get stopped by the wall but this is easily the highest-quality pygame tutorial I've seen so far, I'm excited to follow it.

Don't be deceived by the short run time... this project is beefy and it comes at you real fast. Thank you for this... the math makes my head hurt but I feel it's getting clearer the more I look at it and practice.

I had texture smudging and ended up having to do a little bug hunting. I accidentally had a: objectToRender = [] Instead of: objectsToRender = [] Always remember to check your variables! I've been doing this tutorial when I'm getting distracted from school work. I've been putting my own spin on things, with plans to make it more modular so it functions more as an engine. Very good tutorial!

That was very informative, well explained and animated. Thank you.

Wow tremendous job! Thanks for your efforts!

Impressive. Python is probably about my 4th language after C#/C++/JS, not done anything large apart from a Django ecommerce project, so a pygame would be interesting, just never had to use anything other than Unity or UE to create a large game. Good stuff and interesting to see python used outside of server side web dev. 👌🏽

That is a great guide! Maybe you also have an advise about how to make a non-static floor? I mean, if I would like to have different textures, like in the case of walls, how would you do that?

GREAT JOB! I started teaching my kid how to program in Python. Your code is a great resource and a motivator for him to see what he can achieve with less than 1000 lines of code.

Very nice Python tutorial for creating a DOOM style game. The only major issue that I can see here is the mixing of the "Engine" code with "GameLogic/Rules" code. With this type of approach it will make it quite difficult to reuse the "Engine" code within future projects. Coming from a C++ background the "Engine" code should be completely agnostic of any Game Logic code. It should only be responsible for knowing how to draw elements, knowing how to process sound and to trigger user events, calculating basic physics - collisions, processing animations, networking, and resource(assets) management. Anything that is game related such as the assets themselves(textures, sprites, audio files, etc...), game logic, rules, personal settings, etc. should be abstracted out of the engine into its own project. The Game project would rely completely on the Engine project where the Engine project should have no dependencies on the game itself. This would allow for more of a modular and generic programming style to give the developer ease of use of reusable code down the road. In simple terms if you wanted to make a second game with this approach all of the "Engine" code or boilerplate code would already exist as a library. You would only then need to include or import it into a new "Game Project" and add the necessary game logic for the next title. Maybe in the next title you want the player movement to be different, maybe you want a different camera style such as 3rd person, maybe you want to add new abilities such as crouching and or jumping mechanics... Having these layers of abstraction early on helps in the long run. Other than this type of programming philosophy, this video is very well done on quickly explaining all of the required steps into making a DOOM style game. Then again one could argue that "Pygame" is that engine... I'm use to writing the actual DirectX, OpenGL, and or Vulkan code to implement the renders and shader modules.

@@CoderSpaceChannel Yeah, your code implementation looks great, your code style is good. In the future if you decide to make another game, you wouldn't have to start all over, you can just import your engine. You may have to make minor changes based on the type of game your making though. A FPS compared to a RTS compared to a RPG type game does use different frameworks, but even these for the most common parts can still be abstracted away. Yeah, keeping the game code seperated from the engine code helps in the long run. You don't have to go back later and try to figure out what is game code vs what is engine code to rip it out with a high chance of breaking the engine code. It can save a lot of future headaches, head scratching, and hair pulling.

While this tutorial definitely had some great merits and I really learned a lot, there are some areas that I felt needed improving. The speed of the automatic voice narrator was very fast, along with showing what to do, but at least that was remedied by adjusting the playback settings in KZread to a slower speed. And, rewinding a lot. Also, towards the end I noticed that some parts of what was shown in the final result of the game did not match up with the coding you showed along the way. It appears that a lot of information was left out: the extra soldier sprite and Hell Demons, the "Victory" screen, background music, larger map layout, and the additional red torches. I was confused as to why my final result didn't match up to what was shown in this video until I compared the files on your GitHub and noticed some code blocks were never mentioned in the tutorial. While I do understand that a tutorial can help give a basic understanding of some things, I feel that it would be beneficial to also mention that the final result shown on screen will differ to what was presented code-wise, and to use the knowledge given in the video to try and implement the rest on one's own.

Hey there, Wanted to give a big thanks for going through likely days of researching, testing, and editing together this project. Used to be reluctant about following along videos because it seemed too much like copying, but I also learned that’s how we learn. I learned a lot about organization by getting used to how everything was structured, learned how to coordinate my mental reasoning more efficiently, and most of all, learned a lot more about bringing python beyond the shackles of 2D. I have 15 pages of notes. I’d take time to first code along with the video during my homeschool week, then during the weekend, I’d dissect all the mathematics and mechanics on paper. Mind you, my previous game was just two-player atari breakout (and god, how horrified I am about my old code, no words). Previously, I only learned code just for the sake of being able to read it, being able to pass tests on documentation, never intended to make anything. But ever since, I’ve been working towards game development as a side.

Man... This was beautiful. Every 5min or so, I was trying to click the like button again...
