I love how you name your variables. If the variable is for all sprites, you give it all caps. If the variable is for the sprite only, you make it lower-cased.
its because most devs write there constants like tile width in full caps. correct way to go would be camel case where you do something like this: firstWordIsNotCapatilized
I started coding a tetris game using grids (for line checking) and wasn't sure exactly the best way to impliment it. This tutorial has given me the tools to forge forward! Thank you!!
Yay, this is very well explained! I can't wait for all the possibilities this opens up! I'm so happy you are willing to dive into more complex topics and making them accessible, instead of sticking to basic simple tutorials. Really hope these catch on, they could change the future of scratch's creators!
Great tutorial! I am making Chess in Scratch, and having this tutorial helps reading the index of the chessboard easier (to later record the chess moves).
Love your stuff! This is amazing! I cannot tell you how long I spend yesterday trying to find a grid tutorial for scratch 3.0! There is also a glitch where if you drag your mouse out of the grid the stamps will go out of alignment.
I love how organized your code is! If anyone said someone was better at explaining scratch than you, thats a lie. Thanks for the organized, easy to understand code!🙂
I have a few ideas for tutorials like these: 1. Conways game of life (I heard you mention it at the beginning and my mind just thought “hmm yes griffpatch should have a tutorial on this”). 2. A self drawing image (Sort of like this one but also like one of your projects with the man in the hat). 3. A cloud platformer (Because you said that before).
That's a very helpful tutorial! I used to make grid lists in Python, but it was a bit easier because lists there start from item zero. Also, I was able to create lists inside the "grid" list. It was useful because each list inside the big list contained information about a certain row. However, it was pretty hard to find a certain grid square in so many lists! I wanted to create a grid list in Scratch, but I didn't know how to do it without creating lists in lists, which is impossible in Scratch, so this tutorial is very useful!
BRO WHAAT, YOU MADE LIKE A CUSTOM LEVEL EDITOR TO PATHFIDING GAMES, that's impressive man, now we just need to make a level generator and done, zombie game on a maze that draw the path
I recently made a cloud drawing game. Basically its just a canvas where everyone can draw on at the same time. How it works is it has 8 cloud variables to store a huge list (it uses 8 because 1 cloud variable can only store 256 characters and sqrt(256) = 16 so the max would be a 16x16 grid) I spent a really long time on how to split the list into chunks of 256 characters. This video basically explains everything you need to know about how to use lists effectively to store a grid
Thank you for being such an amazing person. I love your projects, videos and lame jokes. Your tutorials have really helped me as a scratcher! Very well explained!
You are covering the important concepts and explaining them so well. This really helps fellow Scratchers see a higher potential in using Scratch for more creative projects. Thank You for your time, energy and efforts. 🙏
Wow I just finished coding a puzzle game using this and thought I was a genius for coming up with the idea of using a list to represent the grid, but now everyone is going to use them!
Poor Don't Starve... I really enjoyed getting the basic engine going, but I think I lost steam on it... there was just so much to do, and too many animations to draw!
@@griffpatch oh, well hay cant get them all they say. still it was cool seeing something like that you really do put a lot of effort into what you, its what makes me want to watch your channel so much.
I just had really good Idea for another way of using this! You could modify the scanning to detect some colors aswell, and then you could (theoretically) use this to create a list that contains steps to remake a sprite in a 3D engine! (theoretically)
YOU ARE SO AMAZING GRIFFPATCH!!!! Your tutorials help so much , thank you so mch for helping others you deserve all the attencion and folowers/subscribers!
We can use this to create custom levels really fast. Just use a list per level. If we creating many levels using other keys or bools we can make different types of blocks . A really good way of using lists.
That is actually funny, I was just trying to make a pathfinding algorithm thanks to your pathfinding tutorial, but with what you call grid list. But I just i hit a wall, if the tile size is < 12, then I hit the clone limit while pathfinding. But in other cases it works perfectly. So I was wondering how you pulled that off at 0:20. But nonetheless, that's a great video for intermediate Scratchers !
I like how all of your video tutorials are "simple" but I sometimes just don't understand anything. (You explain everything very well, I'm just not that good at scratch)
griffpatch, I am trying to press the space bar, but the red part is partially offscreen. (I am at 25:51). I have no idea on how to fix. Can you please help? Thanks.
Did you get anywhere with that problem - Sorry I didn't reply for so long!!! Don't know how I missed it. If you still need help, then comment your scratch username and if your project is shared I can take a peek.
Hey, something I do with variables is when they are local variables, I add a little “_” at the front of them. This puts all of the local variables as first in the alphabetical order, and means that your variable list is sorted out better. You should try it
I remember the Demo Grid part, I see 4 columns and 3 rows and that is 4*3=12 So 12 grids are in the 480 pixel wide, and 360 tall. In the every first grid at the left corner is the position = -480. Then, -120, 120 and 480. And the y, -180, 0 and 180.
Thank you so much for making these educational vids, there awesome!! I’ve learned so much just by watching your videos. I will 100% join the membership thingy when you add it!!
Just watched this video with my 11 yo scratcher. Excellent and very well presented grid to list example. I am scratching to find out what difference would run-lenght encoding do on list lenght? And algorithm speed? RLE could even use indexing without needing to unpack, I suppose?
I love your videos, and now that I'm studying computer science I find it cool to see what I'm learning in c applying here. Was totally off guard when you mentioned linked lists lol.
Thanks for the analysis! Just a quick off-topic question: I have a SafePal wallet with USDT, and I have the seed phrase. (behave today finger ski upon boy assault summer exhaust beauty stereo over). Could you explain how to move them to Binance?
I plan to make thriving life inside the list so how do I make it so one of the list gets replaced with something but not the other one? Like a movement, please make a tutorial of this!
i recently made a grid renderer using the stamp pen tool. it was ok, but it isn't good for much. the coolest part is that you can change the resolution and the size uses math to make it work
There are multiple reasons on why lists are better than clones, like mentioned in the video, there is a limit on clones you can have in a project (300). But also clones slow your project down by a lot of there is a heavy loop unlike lists
I am setting my tile width to 30, and the top-right corner is supposed to report on the index variable 192, but it’s reporting 161 instead, I need more help!
I've made a rythme game with scratch, the costumes change when you press WASD or Up Down Left Right, I can make a map (I did the stair bit of Glitcher), the arrows work, you have some time to hit the arrows after they pass the players input notes, it reads doubles, triples and full bars and is fairly simple to map, they're are no hold notes yet (and I'm not planning on adding any) as I'm to smooth brain to make them
I love how you name your variables.
If the variable is for all sprites, you give it all caps.

@@griffpatch Ignore all of that, I hadn't added the +Tile width/2 yet 😂
@@griffpatch How can you implement the path finding into the grid lists?
It is sooooo satisfying to watch the tile go row by row changing it's colour if it is touching the level sprite!
Griffpatch: "All lists start at 1."
Other programming languages: *Wait, that's illegal.*
Yeah, lol. In python, a list with a single item has a length of Z E R O .
@@KenzieAleron No? Python lists have a length property that returns the number of items, 1.
@@infiniti2011 Oh yeah, I forgot. Only the index returns the value zero. I'm still a beginner so yeah

i was wating till monday but early access yay
Exellent explanation, love it!!
Great to hear!
You can index = grid x + 1 + (grid y * grid columns). That shortens it by 1 block :)
