Something I want to point out - This is **not** Mode 7, this is simply a perspective projection (which, while was possible using Mode 7, was not the only purpose) Mode 7 on the Super Nintendo was a Hardware Acceleration feature that allowed a background layer to be adjusted using an Affine Transformation.

*adjusts glasses* "well, acktually..."

Retro Game Mechanics Explained covers this topic in his SNES series. The familiar “mode 7” perspective also depends on HDMA varying the scale factor over time as the screen is drawn.

[@eddievhfan1984]

It's worth noting that in the IRL Super NES/Super Famicom, that Mode 7 was natively only capable of doing linear matrix transformations (translate, rotate, scale, skew). In order to get these 3D perspectives, the console could run small graphics attribute updates at the end of every video scanline (H-DMA, horizontal blanking Direct Memory Access), changing the Mode 7 transformation matrix on each line to simulate a non-linear transform. This is also used to get different "sky" and "floor" patterns, as Mode 7 supported only one background layer; you'd draw the sky, then rapidly mirror the floor graphics into the graphics memory.

For those who might follow along with this tutorial and write the code as it goes, note that you will not be able to get a display window to pop up (seen at 2:40 and 3:30) if you have created only a mode7 and settings file. The reason it works for them (and wasn't explained from the beginning) is because they're using PyCharm and, when they run the code in the mode7 file, their configuration is set to work off of the main file they already have coded out. Note: As of this writing, Numba is only compatible with Python 3.7-3.10, and NumPy versions 1.18-1.23. They are currently working on updating it to work with Python 3.11.

Magnificent tutorial. Brings back memories of writing a ray-caster demo many years ago.

[@sulrich70]

Incredible. Thank you. It’s simple the way you do this, but it’s also hard!

[@gawd0r]

Amazing video, so beautiful to see stuff that I used to implement in days in assembly, being done in a few python lines. Excellent tutorial!

I hate this recent "trend" of using ai voices in videos. Please let us hear your voice, it is not a bad one I am sure, it can't be worse than the emotionless ai voices.

[@K5RTO]

Nice! I am really enjoying your channel. Keep up the good work.

とても参考になる興味深い解説です！ 細部まで理解して、自分でも実装してみます

[@HandlebarOrionX]

Such a brilliant looking effect

[@randy7894]

Just what I needed! Ty

[@omarsilva924]

Well done! Impressive channel. Love how much more you get out of pygame. I’d love if you make a video about driving game from the driver perspective

[@user-dc9zo7ek5j]

Amazing work, I remember I played a game with similar effect 15 years ago, I think it was final fantasy but I might be mistaken.

[@VeraVoxel]

you know they could easily sell a gimped piece of doom by just adding a second background, but scaled from the top instead to seem like a ceiling. And then the walls could be moving sprites. And the floor of course is the normal mode 7 layer.

[@thelucin]

wow, thanks for the new video!

[@gianlucagiuman6132]

Super !! High level teacher updated on latest news for library !! i remeber the old demo on amiga....

[@johneygd]

For two decades i always tout that mode7 could move a background in 3D space including 3D rotation in all directions,BUT as it turns out,a background doesn’t move in 3D space,instead a background is scewed,stretched,shrinked in whether form to fake 3D movement of it but in reality it just uses perspective correction to give the elussion of a background moving in 3D, Pretty clever, Same thing with sprite scaling trough software, Now even if a background and a sprite could,ve move in 3D space,i still would,ve considered that as fake 3D as well since everything would,ve be still flat anyway,except that it would,ve look smoother.

[@SkyFly19853]

I love retro style...

[@dietrichdietrich7763]

wow this is very interesting. I love 3D effects.

great video! please continue creating tuts about interesting topics like this

I love this I'm gonna try to make a flying game via mode 7

[@costelinha1867]

People: Pygame isn't exactly suited for 3d game develpment. Coder Space: Make a shit ton of videos on how to do 3d/pseudo 3d game development in Pygame.

[@zhabiboss]

You should make a series with nostalgic games

[@ThankYouESM]

Liked and already sub'd! I wish there was a way to also create HTML5 games at least from our Python scripts, especially because I have far more time to play smartphone games as opposed to PC games.

[@user-lo2qv8wz8f]

so nice^^

[@blurayys]

Love this! Do you think you could make a tutorial on 2.5d, where you are a 2d character in a 3d environment? (Like Pokemon Diamond and Pearl)

[@CoderSpaceChannel]

I'll think about it

[@dekerus3]

​@@CoderSpaceChannel lolz!

[@spikkit]

I was able to implement this into your previous DOOM-like tutorial, but it looks super janky. Like, it displays the floor and ceiling properly, and I have it use the players position and angle to move it around which also works, but it looks like its all detached from the walls. Any suggestions on how this could be fixed?

[@spikkit]

I think i has to do with the FOV not matching between the wall projection and the floor/ceiling projection, but I'm not sure how to remedy this.

Hmmm how can i bend the plane to make it like a sonic 3 special stage style?

[@phillippi2]

I wonder; is it possible to use this with a Wolfenstein 3d style ray cast for drawing walls?

[@djaccount5458]

Hello, how put object on projected plane, i have no idea!!!

[@HrvRockstar12]

lol I don't even know how to get to the first menu that he got. How do you get GMS2 to recognize these files? Also - will this overwrite how Game Maker Studio 2 will run? I have other levels that do not use this.

[@IdkFlyCasual]

i feel as if this should be easy to add to your wolfenstein game. any tips?

[@lanchanoinguyen2914]

Which api you use?

[@cookiepolice2086]

What does dx, dy and focal length mean? And thx.

[@CoderSpaceChannel]

dx, dy - increments, one step on a 2d plane, along the x and y axes fol_len - distance from the camera to our screen

You have a typo in your description, "Paygame" should be "Pygame".
