I think this just proves how dynamic Scratch can be. Not just a kid's coding site, but a whole new world!

The next episode should be about sliding doors since it seemed like the right progression to this series. And honestly, most ray casters have doors.

Everytime I think something's just impossible in Scratch, you never fail to amaze me.

I didn't realize you did tutorials! When I was younger, I remember spending a long time playing your projects like scratcharia and paper minecraft. Now, I've kind of moved on from scratch to python (Plus a bit of java). Your creations were one of the things that got me into programming. Thank you.

WOO HOO! Was constantly checking your channel waiting for this part, super excited to get this working!

i very rarely even use scratch anymore, i just find your videos entertaining. and its cool to see how people are really pushing scratch to its limits

This tutorial is literally perfect for the backrooms

I like how with just this, we can make a whole 3d action game, a 3d moviemaker, a fun maze, etc, yet there is bound to be more episodes. This is awesome!

This is just what I needed to finish my game thank you

This is the best series yet! Could you add a cloud server, sounds hard but would be another fantastic achievement.

Holy crap! I remember following you on Scratch back in high school several years ago. I was eagerly awaiting for each new update to your Gauntlet remake to try in the mornings before school started. This is such a pleasant surprise to find you making videos! You inspired me to try and make video games myself!

This is so cool! I do have some more ideas for more improvements, including one optimization: 1. The optimization idea is implementing draw distance. I noticed that wide open areas with far away walls cause some slowdown because the raycaster has to travel farther, even with the Episode 6 optimization, but those far away areas are basically pitch black. So there's no point in raycasting that far anyway let alone draw there, so I'm thinking having an adjustable limit to how far a ray travels, and then just not drawing any of the walls beyond that range, could save resources as that reduces the amount of raycasting done, and how much we have to draw with the pen. With some clever adjusting of the background image so that there's a taller black bar in the middle, given how dark far away walls are, this could be made so that it doesn't even become noticeable that far away walls aren't getting drawn or even detected. 2. I wonder if it's possible to allow for really large maps by merging this with a sidescrolling engine. Like, for starters, adjust the movement so that instead of the player moving and the level sprite remaining fixed, the level sprite moves instead while the player remains fixed. And then use a sidescrolling engine on the level sprite to allow for multiple screens of the level sprite that scroll together on the map, and since the player remains fixed and the level moves via the sidescrolling engine, this could potentially allow for theoretically infinite levels without having to make a ginormous level costume or tax performance. In fact, I believe this is exactly how the Doom engine worked, where the level moves instead while the player remains fixed, and different areas kinda get loaded as the player gets close to them.

Just wow. I'm only up to ep 2 regards coding but I love watching each vid as it comes out.

This is truly amazing! It's going to be interesting to see what else we will do with this. Anyways, I'm going to implement this into my project now. Scratch on!

Just finished the series. I love it. Please add more!

Wow oh wow, this Raycaster just keeps getting better and better! This is my favorite series from you so far; I've learned so much! I know multiple people have already suggested it, but would you be able to make a video on looking up and down & going up/down slopes and stairs? Thanks either way! 😁

These videos keep getting better and better. Keep up the hard work! Can't wait to see what you have for us next!

it's as if you can bend scratch to your will, it's incredible what can be done is such a seemingly simple software

This is honestly amazing. It opens up so many different opportunities for a ray caster. Wow!!

thank you so much. i really love your vids. btw congrats for 200.000 subs!

This is awesome! :D I could've never thought this one out lol, and I have to say, you're a really hard working youtuber! Most people (even me) take 2 weeks to post a 10 minute video, but you are posting 15-30 minute videos every week! I have to respect that lol

This is just incredible. Keep up the good work man!

this... is... awesome! this again reminds us that the making of a good game lies in the hands of the dev and not the software. Although the concepts are pretty hard to understand and its very easy to get lost even with griffpatchs simplest and most straight foward explaination, watching your raycaster comes to life is just such an rewarding and satisfying feeling. this is definately worth spending my weekend on. and thank you griffpatch for everything you've done to inspire more people as you have on me :)

I came back to this series when I saw I needed raycasting and am thoroughly impressed griffpatch could come up with solutions to these seemingly impossible roadblocks so, good job!

When Griffpatch uploads, it's a good day

I think wall and floor textures could be a great addition! It might be a bit tricky, though.

yay! i love those wall textures!

Very interesting solutions! Texture mapping floor and ceiling next ep perhaps?

Although it feels like some parts may have been done a little simplier, this is such a great tutorial with some really interesting ideas!

This man is doing real 3D in scratch. He has ascend.

I'm speechless! YOU ARE A REAL SCRATCH HERO!!

Question (maybe for an episode 8?): How could I add animated entities?

200th like and a really amazing tutorial overall! it's a really good episode and the most wanted and the most IMPORTANT episode ever! that you have got us to see and build the program ourselves 'nice job griffpatch'

This is so amazing! Thanks for making this video!

This was really fun :D thank you so much for this

This is awesome. It's crazy to see how far this series has come from just a simple raycaster. One thing that I have been wondering is how would we add things like stairs or other shapes to add depth, similar to your 3D Laser Tag game?

There are soooo many things I would like them to be added! Like Ceiling and floor textures, animated sprites, Wall heights, jumping crawling, etc!! I hope you can teach us

wow! I haven't watched one of your videos since the original scrolling platformer engine video series. you really seem excited to make these videos, thats great! 10/10 video!

YOU ARE LEGENDARY SCRATCHER!!! I am a big fan.. thanks to do such a big coding also for making all this tutorials for us I have started coding this video and my project will be ready soon . #awesome#

the perfect ending for this would be adding ceiling and floors with textures, and probably fog, if possible

THIS IS SOOO COOL!!!! I HAVE NEVER SEEN A 3D SCRATCH GAME THAT CAN RUN AT THESE SPEEDS AND HAVE TEXTURES!!!!!! YOU ARE A GOD

to think this was the same scratch i used to make simple point-and-click games this is incredible, You made your own 3-D game engine.

griffpatch can explain anything on his tutorial and unlike other tutorials, I understand how it works! Amazing explanation at the start btw

Hey griffpatch, huge fan! Just wondering if we're ever gonna add projectiles and animated enemies like Doom or Wolfenstein?

Woah, this is actually next level

the man did it good job man!

i've been keeping an eye on the ray caster playlist for days waiting for this to come out, it is really exciting, i think this is what we all needed, thank you. but i still have to mention some things i would like to see in the future of this series, here are a few: -maybe getting the roof/floor to move with the walls -smarter AI for the enemies -perhaps the ability to look up and down -perhaps the ability to jump and /or sneak -perhaps the ability to layer multiple maps on top of each other as to mimic full 3D -even having small objects that can move freely in all directions without appearing as walls

Could you show us how to make varying level heights like in your first person shooter? And maybe we can use the same technique to render walls and ceilings.

I didn't realize you could search for blocks just with the first two letters of it! That's going to save me lots of time, thanks Griffpatch!

I love how he does this with drag and drop blocks.

Amazing like always! I wonder if it would be possible to have a texture for floors and ceilings too instead of just having a basic background for them.

ngl I find just *watching* these tutorials pretty relaxing for an unknown reason

dude this is actually insane

This is Amazing! so fun to create and follow! can you maybe try to add a minimap later on? Thank you anyways for being such an awesome content creator and by far my favorite! Have a good day!

How about animated floor and roof? Like it moves as you move that would be amazing 😀

This is huge! Crazy.

I love this episode! I was waiting a long time for this :D

Wow! I cant wait for episode 8!

This is such an amazing tutorial and I think I can add this to my infinite level generator. Thank you for making these easy to follow tutorials! :D (Also is it possible to do different textures for the floor and ceiling that rotates with the player? It will be incredible if you could make a tutorial on that! :D ).

I think in the next episode you should make textures for floor and ceiling (if its possible)

I loved!

ive been playing this guys games on scratch an HOLY COW mans a legend!

I couldn't get the extra entity to disappear for some reason so I had to set up code to add spawn protection so if your x pos/y pos is -10 to 10 you can't get damaged which is actually a feature worth keeping even if I fix the extra entity. If anyone wants the simple code: 1. Make 2 new variables called "at spawn" and "temp" or "num" (whichever you prefer), both for this sprite only 2. Make a new block called "Check if at spawn" and set it to run without screen refresh 3. Add this code in the block: define Check if at spawn: set [temp] to (-11) repeat (21) | change [temp] by (1) | if then | | set [at spawn] to (1) | | stop [this script] | else | | set [at spawn] to (0) 4. Change the code inside of if to: Check if at spawn if | change [Health] by (-1) | if then | | broadcast (Game Over) 5. Now you're done! Thanks for using my code that I shared for 0 reason! :)

What if you added a floor and ceiling? I can kinda see how it could work. Something to do with the height variable

Damn, I remember your games from when I was a kid, they inspired me a lot to do game dev stuff proper. Thank you

Awesome video! What's next? Different height walls might be cool to implement, before moving on to stairs, a second level and vertical movement.

If I'm not mistaken, technically using this, someone could make doom in scratch

Second time asking: Add mouse look. and i tried changing the map last episode and the project broke, luckily i had backups! also i love your videos griffpatch!

Perfect project, Griffpatch u are the best

Great videos! I have now learnt the things that Scratch can do. I only figured out that 3D projects can be done on the platform through the 3D Block with Shadow project. It seemed crazy to me at the time, but I love how versatile Scratch is as a software.

This is amazing! I love it! A suggestion. I really would like to create a 3d platformer like some other people did. Is this possible with sprite based raycasting? If so, I would love an episode about it!

Wow! This is wonderful! I'd recommend color coding the level so that you can see different textures at different positions.

Griffpatch is so good at coding he could probably code this on scratch Jr.

i keep rewatching this video because its so fascinating

my 3 questions: are floor and ceiling textures possible? is it possible to make more uniquely shaped walls instead of just verticle blocks? and what about vertical movement?

Could we possibly raycast and texture map the floor too?

Who knew that scratch could do so much! I remember when I thought NES games in scratch was pushing it to the limits! Maybe you could do something for ceiling and ground tiles so that we can maybe go outside or have the floors change textures? Continue the great work!

Great video as always! If there is an Episode 8, I’d love to see Projectiles & Jumping in the future!

Can you please make a tutorial on making a tower defense game like btd 6 griffpatch? Your tutorials are simple and plus you would make it easy to follow along.

im not even making my own game but the videos are just so good not to watch, Thank you griffpatch for making this video.😄

The fact this dude can make 3D in a 2D code interpreter, is awesome. And out of simple block code too!

I love this tutorial! I am using this along with Lemonoids to make a 3D Lemonoids game!

Just an idea: What if we make textured floors??? (edit): We can apply the same concept for the walls, except we would need to calculate the proporions of each pixel of the texture and then draw it before we draw the walls. Don't know if that would slowdown the frames tho

backrooms reference?

Griffpatch you are AMAZING!!!

Thank you this whole series was very helpful and allowed me to create fully functional game 🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩

I've went through this entire video and i cant figure out why my walls arent showing

A list of things that can be added in upcoming episodes: 1- reflections 2- textured roof and floor 3- 3d modeled things (example: a table) 4- jumping and crouching 5- things at diferent heights (a stair or multiple floors) How i can add transparent textures to my walls? I am triying to implement enemy healtbars and i am going to send the game to the studio (minecraft textures included ☺)

Thanks for Tutorial, This is Helpuful.

this is sooooo cool, i'm in a ickk scratch race and this just gave my a animatio;n a idea!

Another Great Episode! I kind of already knew how this was gonna work but I didn't expect every texture to be in one list! Also kind of a weird question, But I managed to modify this project to also have a Camera Y Value and the ability to look up and down, and was wondering if it was Ok if I could post a tutorial to my channel?

Wow this is amazing! It looks like Doom!

I love this tutorial series. It would be even better if you added projectiles, like you said.

I hope the next episode is about texturing the roof & ceiling!

Ooo yeah, thank you very much griffpatch 👍

First off, this is an amazing tutorial! Now really all I’m curious about are enemies and wether it’s possible to make them more fun to play against. For example, if enemies will only chance you within a certain distance, or maybe even enemy projectiles would be awesome!

Thank you so much!

finally i can make some awesome game through your game episode an alternate of ue5 nanite feature great work your really awesome !!!!

Never thought this was possible on scratch!

Thank you só much to thank i added you into my game 😃
