Now I finally understand why Minecraft completely breaks when you swap the sin and cos functions. I used to think they weren't very important, but it turns out they're used a ton for rendering 3D games! I had no idea!
i'm makin one of these in python, and this was the best tutorial I could find! , even though it isn't in python, the way he makes complex concepts so easy to grasp is brilliant!
I love how griffpatch shares his knowledge to other Scratchers that needed help on their projects. I often learned how to use blocks that I haven't used before.
you just gotta love griffpatch's videos, he's just always so cheerful and fun to watch! just how he interacts with Nano is fun and playful, and it just creates such a welcoming and happy atmosphere for the video. absolutely just a joy to watch and follow along
It would be really cool to see how to make the walls have patterns, add looking up and down, add objects and make the map bigger using some sort of scrolling mechanism. Maybe even add random or infinite map generation.
I bet you could do it with lists. You could probably turn a list into a cube list instead of a grid list, and store the colors as the values for the list. When the raycaster senses a wall, it can detect what color you want by what value is in the list
This is hands down, my favorite series in all of UA-cam. (I really love programming.) so ofc, griffpatch’s series are the best, and his 3D series is definately the best series out of all of the ones he had made. All of this 3D stuff is super cool, and makes me super excited. I love it!!! I hope griffpatch doesn’t hold back on fear that it might get to difficult. I really love learning about all of this, and am really confident in my ability to follow along. I want to put all of this 3D stuff to it’s fullest potential.
When I turn away from my entity, it just gets bigger and bigger until it loops back around, becomes really small, and then grows again until i'm looking back at it.
This is probably one of the best ray-casting tutorials out there! However, I really need to be able to hide enemies and not see them through walls soon, so if you could release episode 4 soon that would be amazing!!! Thank you!!!
Hello, I love what you do and I'm a scrapper too! And thanks to you, I'm getting better and better! Thank you for these tutorials that allow passionate scratcher like me to do things (like you) incredible!
Wow I love it, its so easy to copy these tutorials and slowly, I'm becoming smarter in coding! I'm sure all your fans are having the same thing griffpatch! We all would like to thank you for this!
Method of creating a floor: after drawing a ray, you need to set the brightness to 100% and set the color of which will be the floor and after that you need to move the drawing lines to the edge of the map.
I understand the whole thing and even came up with the rotation beforehand with complex numbers but I would have never come up with this myself. Amazing work griffpatch! However I think an SDF raymarching that allows for a z position would be great to have. Here are some useful formulas if you need them: Union of A and B: min(a, b) Intersection of A and B: max(a, b) B subtracted from A: max(a, -b) Where a and b are the SDFs of A and B respectively.
@@jofsalter He means scaling down the collisions of the map and sticking it in the top right as another sprite, but I don't know about the player and other stuff
Hey griffpatch, love your tutorials. They are very clear and in depth. I have a request, can you make a video on a topic we all are afraid of? Lists! Seeing your other tutorials I am sure that you'll explain this topic very well. Thanks
I used your random maze script with this project as well. i had to change the stamping of corridors into clones to get it working in game, however the moment i start raycasting clones, the game gets really laggy compared to when it was only raycasting off a single large sprite. anyone find a way to generate random mazes without lagging the raycaster?
only issue(s) 1. Alot of M A T H 2. How to make the pen correctly draw the texture but its a great idea since textured floors and walls makes the game look better
I love his humorous and fun way to teach. The other tutors are usually like, put this and that and here and there and you have it, your game. We don’t learn anything.
I made some slight changes with the FOV change, In "Define (Single Ray)" script, scroll down until you see the "set pen brightness" block. "Set pen brightness to (120 - (distance / (DV / 300)))" When you do that, when you slide up the fov, the brightness will change even darker, like the player moving.
@@Aiaimonkey8093 thats actually simpler than you think, you can just make it when the player touches a sprite on the map, teleport them to this x and this y. and you can also add raycasting to that as well
I'd love to see how I can make the player look up or down, and how to move the camera with the mouse, like in games like COD or Minecraft, it would be VERY useful :D

If you are going to make a new one, could you add textured walls?? Maybe with sprites or pen patterns
only issue(s)
1. Alot of M A T H
2. How to make the pen correctly draw the texture
but its a great idea since textured floors and walls makes the game look better
@@PrivacyNProgramming no its simple, you can just use another go to x x y 0-height/2 pen down set y to height/2 pen up
@@Pratixxoh, i thought it would be much harder but thanks :)
@@PrivacyNProgramming actually i messed this up a bit, you just tweak it around a bit and it should then eventually work
@@Pratixx oh ok, its fine since we can wait till the next part :)
If it's possible, you should make a episode where you can change the walls appearance, have ramps or stairs or make it able to have outside areas
deffinitly
Probably could he made on with stairs before
that impossible because in episode one he said make sure there are no gaps otherwise we would get great lag
To make stairs, you need to heavily modify scripts to make the project support stair collision.
@@maxsanby9974 It is possible, you just need a different type of raycaster. Adding stairs does not mean you have to leave gaps on the edge.
This is just amazing! I hope you will release some more videos on how to add stuff in 3D!! Btw. this game reminds me of The elder scrolls 1 or 2 :D
I love how much this looks like you're just teaching us how to make it run Doom. Because Doom looks a lot like it uses the same formulas!
