I remember looking at griffpatch’s projects on scratch as a kid and being amazed. Now, when I understand everything happening it’s even more amazing

[EpicVideos]

I'm still amazed that a project that uses the touching block can render something complex like this in real time, but it's impressive definitely.

As I said on the last episode, this has so much potential!! I think I'll try implementing a grid list system to let myself have more control over colour, and possibly create a level editor. This has genuinely been the best tutorial series I've ever watched, and I can't wait to see what the community creates with it. Keep Scratching, y'all!

[DDP-Gaming]

I can already see so many games on scratch when they find this amazing tutorial... Absolutely Awesome!

[duckcatthequrugosk]

I'm not even using this as a tutorial, I just love how this guy does their magic

[ItsADG]

I started to take Scratch lessons like 1 month ago, and these tutorials will help in the Scratch classes. I love your tutorials!

I used raycasting for a platforming game to prevent the player from standing up after crawling if something is right above them. This really helped me out with it

Here's an extra tip to make a nice looking raycaster. Under the "Single Ray" block, you can go down to the "set pen brightness block" and place a "change pen color by" block under it. place ( distance / 20 ) inside, and it will make it so the farther away the wall is the deeper of a color it will be

[karllospinto]

Tip for decreasing corner flickering: Make player forward and backward velocity a multiple of the ray velocity.

[Gacha_Snobby]

So cool! I love how you not only show us how to make it but you also show how it WORKS!! You are so cool and now I understand actually how this works!

[Unknown-jmix]

the ray casting makes me think of a top-down view games where you are sneaking into a place and an ai guard has a flash light and if you touch in the light you get caught! also ty for making these tutorials! they are really helpful :D

[funut]

Awesome video, imagine instead of using level sprite you used your grid based list! Add maze generation on top of that! Man, lots of great ideas here...

[VSpook]

I'm impressed how scratch can make these things, i thought it was more limited, but your tutorials proved me wrong, keep it going!

[Davi-zolu]

12:06 this raycasting is great, it could be great to use for enemy visions, to make stealth games

[thecringeslayer]

coming back to these tutorials years later as a game dev is insane, I understand everything now!

[lakyk]

I have been waiting for this part for a while now, and I am definitely not disappointed! This tutorial is leagues better than the Scratch Wiki one in my opinion :)

[BJIADUS]

Thank you Griffpatch for releasing Part 2! I was just making a 3D game, you helped me learn 3D in Scratch

[RepressedButton]

This is a note for people who are having this problem: I had the issue where my wall colors would show up a little bit on the wrong walls (some walls were 2 colors) to fix this just save the project and refresh Scratch and it should work fine :D

[mortimermouse]

Incredible tutorial. Honestly great for a COMPLETE beginner like me. I don't mind starting from scratch (heh) and working my way up. I always wondered how these scratch raycasters worked. I just made it and i'm still so confused lol.

[Wondercool]

Hey man, I can't express how thankful I truly am. You are an amazing person making all these tutorials for people, so we can all learn how to make wonderful games! I have told you I think in the first video that I am going to make a game. Well because of you that game that I have always wanted to make is now a reality :D You deserve many more subscribers!
