Griffpatch, sometimes, I don't even follow your tutorials. I am just in awe every time you make things happen (especially your raycasting series). You have inspired me to make better projects on my scratch account. Thank you for that.

[@ego-lay_atman-bay]

I've literally moved on to python, html, css, and javascript, yet I still watch griffpatch's videos. I just love to see what incredible things scratchers (like griffpatch) are doing. Oh, I also still check my scratch messages every day, even though I don't get much anymore (besides studio activity).

[@Cool-Crash]

yep

[@haoweilim6484]

Great

[@blengen1]

8:10 That is ... surprisingly smart actually. After seeing your post about this video I've just started working on a cloud-based game, and the way I got around this problem was by keeping the number "9" as a special symbol. Kind of like a "next task" operator. Also useful for finding out where you are in the variable. That does of course imply that every number and letter is a string of two numbers, which is why I could see some insane optimization with your method; to get the absolute most out of what we are offered by scratch.

[@BasketBoy123]

I was gonna follow that entire series for multiplayer a day ago and realised I messed up somewhere...I had quit it and now you upload this at the perfect time!!

I use to spend hours following your tutorials! I took me 2h 45m to do the one that has your text appear letter by letter! As you can see I am not a good coder but you’ve been my inspiration in coding and me and my sister loved playing your minecraft game during online classes! You’ve helped me gain confidence to try learning html and css! It’s very difficult but I hope I can push through! Awesome tutorials btw nobody to explain it in a way I could understand, not even my digits, literacy teacher.

[@boredyoutubeuser]

I really wanna create a multiplayer 3d sandbox game in scratch, and while I don't have enough experience to do that yet, these tutorials really teach me the concepts better!

[@rustam_cpp]

To convert negative values, we can simply add 240 or 360 to them, depending on the coordinate. And add these numbers to the positive values too. I used google translator, so sorry if the text is bad! 😀

[@snojeng]

I was thinking the same thing!

[@SeeThatHuman]

Yes, but it converting the value won't require having to add and remove values, which can be useful when sending many different types of values, having to add and remove different values.

[@fireflash2803]

The text is good

[@WindowsDrawer]

Or just add 500 to both, so you don't have to check the coordinate

[@rustam_cpp]

@@WindowsDrawer Why didn't I think of that right away?

[@LukeAnimador]

Griffpatch is that one person who really help millions of scratchers in one video, this is really impressive!

I think it could be a fun idea if you started a tutorial on simulation projects like The Sims. It would probably be extremely complicated, but maybe worth it in the end. You could program eating, drinking, school, marriage, birth, death, etc., and go wild. You don’t need to do this idea, but I thought it sounded interesting.
