I love your tutorials. They are different from most tutorials since other people tend to just tell you what to do. You do it differently, you explain why and how it works, and just overall gives the viewer more knowledge that they can use later in other projects.

i didnt even watch this tutorial for the tutorial i watched this to see how cool ultra fast scanning is and how it works. i really like the methods you use like using a giant sprite, sizing it down, then switching to a small one, or maybe turning down the image brightness to make scanning easier.. its all very cool, good job griffpatch!

I love these tutorials! I'm a computer science student now, but my original interest in programming came from Scratch. The way you explain how things work in these videos is amazing, it's done in a way that even beginner Scratchers can pick up on, but I still find myself learning new and better ways to organize my code from them. I love seeing how much Scratch can really do, and it is a fun challenge for me to try implementing these projects in other languages like Python or Java. Thank you so much, I'm excited to see your future videos!

Wow. This had my head spinning for a while, but I can't argue with the results. This looks amazing. And it would make for a great jumping off point to make a file compression program such as jpeg or png.

This is so amazing, you're truly one of the best scratchers out here. I also tried the blue line project and it's really fun!

I've gotten this far on learning from you on raycasting in scratch 3d. I'm trying to learn from this video so i can put my own textures for walls and other objects. An attempt to create seemingly random raycasting maps. I cant get past the 2nd scan. I finished the video. Watched this video several times. I know i can catch my mistake. Im using turbo warp. Stantard settings to mimic scratch to avoid errors uploading. Youre such a great tutor. Its so hard to catch my own mistakes. How you broke down this, is mind boggling smart. Yet so simple kids can understand. Bravo 👏

A good idea for saving and loading pictures. Got saving to work before I went to this video but with it saving around 30 pixels a second, so I went to this video to make my saving way faster!

This is legendary! Love this job, it will open a lot of possibilities!!

This is really cool! 8 seconds is definitely an improvement from 20 minutes it was before. If you had a game with a small color palette could you make this work in real-time so you could do cool screen effects to specific things in the game? Since it wouldn't have to check more colors.

Leaving this comment up in case anyone else has trouble. TL:DR if your initial scan test (30:04 into the tutorial) starts glitching out about 50,000 pixels into the scan and the i value starts skyrocketing, make sure that you aren't running the "when space key pressed" code on both your original scanner sprite and the full screen mask. In other words, check to make sure that your "when space key pressed" code block starts with "If costume number >1, then stop this script." ----- INITIAL POST: Running into an issue where my scanner, on intial pass, seems to be freezing up after about 50,000 pixels. Fault seems to be in the "touching color item i of colors" line: the i variable value is continuing to escalate p[ast 8. This seems to indicate that the scanner is looking for a color that isn't in the initial scan color list. Double-checked the tutorial, and both my ghost values and color list lists match yours. Not sure what the issue could be here. UPDATE: Tried a couple of other images, and they all seem to hang around 50,000 pixels. Now wondering whether the issue is somewhere else. If it were a color match issue, I'd expect them to freeze at different points, but they all seem to freeze between 50k and 70k pixels. Wondering if this is a fault in the Scratch color sensing block? SOLVED: Found the issue in the "press space" code block. I forgot to have it stop if the costume number >1. As far as I can tell, the problem seems to have been that when I "borrowed" the code for the "When I receive Scan Pass" block, I forgot to put it back into the original place where it was from. I never checked that code again because I was sure the problem was somewhere in my color values lists. Like a fool. So what happened is that the scanner started its scan, and then the mask clone broadcast another scan pass. This caused it to switch its ghost value to the next value on the list. The main sprite is already in the middle of doing its scan, so the "broadcast and wait" block skips past it and goes on to the next step, which is to broadcast "scan complete." Broadcasting "scan complete" causes the mask sprite to hide itself. . . and suddenly in the middle of its initial scan, the scanner sprite finds the black mask gone and runs into the full array of colors, which causes it to freeze up looking for a color that isn't on its list. Initially, I'd thought that something weird was up with the color sensing block or my mask. Maybe I'd used a color slightly off black or something. I tried fixing this by temporarily changing my initial pass code to run the full "get color" code if it hit the end of the list. . . but then I noticed it was running the full get color code every time after about a quarter-second. When I tried rendering, the first fifth of the image was four-color as expected, then suddenly switched to full color. This told me that something was turning off my full-screen black mask after about a tenth of a second. I tried a few things, like adding a "Am Clone" variable and switching up the order of my code, but it didn't work. Finally, I went back to the start of the video and went step by step comparing my code to griff's, and found the problem at about 18:00 into the tutorial. I spent a moment facepalming, fixed the code, and it worked perfectly.

@@RandomDrawinglol I might try setting it up so that if it reaches the end of the preset colors list and doesn't find the color it's looking for, it records the actual color it is using the slow method. I'm just worried it might cause issues with the later scanning passes. EDIT: Tried this, and found out that the problem appears to be with the broadcast and wait block. For some reason, the code is jumping ahead to "broadcast scan complete and wait" after a split second instead of waiting for the entire scan to finish. EDIT: Found the problem. Feel like a fool. Forgot to stop the script if it's a clone.

i have been waiting for this for a few days

The cleverness of that darkening trick is astounding! You would need to know a lot about how colors work: like I had no idea that "darkening" a color fuzzed it, and "lightening" unfuzzed it so to speak. I wonder if you could do it in reverse? Like instead whiten the screen first and then darken it to reduce the color searches? Anyways: great tutorial on showing us how this works.

I thought a little more about it. Theoretically, we can get ~0.117 fps 480x360 streaming! *Streaming on Scratch, Carl!* Edited: (LONG TEXT WARN) I know the fps will actually be less than 0.117, but we can reduce the resolution: if you scan every 2nd pixel and row, the image will be compressed 4 times (resolution 240x180), increasing fps to 0.468; if you scan every 3rd pixel and row, the image will be compressed 9 times (resolution 160x120), increasing fps to 1.053; if you scan every 4th pixel and row, the image will be compressed 16 times (resolution 160x90), fps will grow to 1.87. if you scan every 5th pixel and row, the compression will be 25 times (resolution 96x72), fps will increase to 2.92; if you scan every 6th pixel and row, the compression will be 36 times (resolution 80x60), fps will grow up to 4.2! And so on, and so on.

You can shorten the time required to detect color by starting search from vlosest number to the last one. So if you have blue plane you will almost instantly scan whole aproxmate color.

Awesome! you are the best! 😀

That's clever. Nice application of the binary search, @geotale! I haven't peeked into your blue line filter yet, but I suspect for uses like this you really only have to do a single line scan at a time, rather than a full image scan, correct? And the 8 second wait (in total) isn't problematic because you're scanning it in realtime with the user. On to texture mapping!
