thank you for continuing this series! i was waiting for the new episode

[@AppliedCryogenics]

Yes! This ^

[@kimeg7294]

Damn, I wonder why we don't have these kinds of projects at our company. Everyone would be smiling the whole day.

[@danhaworth6967]

Have honestly been finding this series so fascinating! Thanks for all your hard work on it :)

[@eruditecode]

Love this project! Thank you for the very entertaining video :)

[@vidgambaws]

This is fantastic work - very much enjoying following along using Dotnet/Monogame. Thanks!

[@mtalhakhalid1679]

Hats off for John Romero and his team

[@thetouristlives]

Whenever I get a notification that you've uploaded another video it makes my day. Thank you for sharing your ongoing phenomenal work 🤘😎🤘

[@acatisfinetoo3018]

Best programming series on youtube...

[@theterri]

I'm learning A LOT from this. Thank you so much

[@yassendimchov8910]

Bro what you are doing is great i cant wait for the next episode

[@abonham82]

Fantastic, I’ve been looking forward to this. I’m following along but translating to Swift and Metal for fun

[@what9418]

These portal walls are interesting. Lately I have been daydreaming about doing a MD version. I'm gonna watch this and who knows.

[@carloprinzi5217]

wonderful series

[@refeals]

amazing as usual

[@damus6665]

Finally, thank you so much

[@prashantm9856]

Nice series , i ❤ too watch

Voxel Cone Tracing + Ray Marching in python

[@guilherme5094]

👍thanks!

[@idjles]

I think this will be the most complex episode.

[@Sebwazhere]

great tutorial! I did end up having to check the code a lot of times as the test at 8:27 didn't work because I misplaced one right bracket

[@sim8816]

👏👏👏

[@coolbrotherf127]

Can you make a series about making Crysis in Perl?

[@bigwhoopgames]

What is the song that plays after E1M1?

[@shadow_blader192]

Using vectors easier and faster, isn't it? (Oh, if you want to use numba, that's can't work (at least for Pygame vectors))

[@Altertoriel]

Numba has been updated!

[@mtalhakhalid1679]

Good tutorial sir why not add Raycast techinque to render and axd hq texture and lights in end if this project

[@CoderSpaceChannel]

yeah, a lot of ideas come up about this

[@rexraptorsaur]

Ohoh boy…I’m already at the second to last vid. Gotta run back through and review everything. Next up is studying the original C code myself….

[@code-dredd]

👍

[@SkyFly19853]

Please, make more videos on creating video games in Python.

[@Altertoriel]

there is a problem, when i run it, the error says: AttributeError: 'NoneType' object has no attribute 'sector'

[@Sebwazhere]

if I try to go to the area left from the start on E1M1 I get the error:
UnboundLocalError: cannot access local variable 'portal_y2' where it is not associated with a value
Edit: it was supposed to be portal_y1!

[@pawxgamingmario9813]

how do i run the code?

[@ianyourgod]

where do you get the ai voice?

[@mantacid1221]

I would like the video but it’s currently at 696 likes at the time of writing this.

pre-calculate all the vertical screen line angles, not for each intersection

talking makes you appear as being a bot, if then else

[@atsanonwadsanthat166]

Ugh, whenever I hear "linedef," my mind automatically adds "...to spawn extra revenants." 🤦‍♂ But wow. And to think that this is all Pygame is just... wow. I've seen platformers, isometric hack-n-slashes, etc., but not an FPS. Wow.

first comment :)

second comment

[@bertiesmith3021]

Turn off the music!

[@kumu2024]

Hate the music .. stop it please

[@oyoplayer]

I don't know if it's normal, but when I tried exploring some maps like E1M2, some walls doesn't render and every time it's a wall with a portal.
I've also noticed than the glitch occur at certain height for some reasons.
This glitch can easily be found in E1M1 of freedom1.wad btw

[@CoderSpaceChannel]

in the next video using textures, I will show how to fix this bug with portal walls

[@oyoplayer]

@@CoderSpaceChannel oh ok

[@supebioshock]

Why didn’t you show how the bug was fixed in the final video?

[@oyoplayer]

@@supebioshock maybe not important enough to be in the video or just haven't fixed it yet

[@supebioshock]

@@oyoplayer oops I forgot to @ him
but I verified he fixed it cause I ran the final code and went to e1m2 where I noticed there was an issue with portals and it was fixed.
I noticed in this videos code. The code before texture mapping that there is an issue with certain sidedefs not having their upper texture listed. I compared it to the code in the next video and this bug was fixed. But I am not sure how that was fixed yet.
I also noticed he did a new way to determine the player height but this was not explained in the video. The method for the new height calculations has a bit of magic numbers unfortunately.
So I believe the bug we see in this video and the one you mentioned has something to do with the player height. Because when I go on e1m2 and go to the elevator to the left… that is when I see there are issues with the rendering. That was fixed though in the final code.
