I already tried it with a "controled cloning" system. That means that i have a generator and every clone has its specific number so you can add things like a x or y coordinate in a list. But pathfinding is something that i need to learn with this system.
@@rubenvanderark4960 there are a few more scripts to put in place, but once you are comfortable using them it actually really free things up to be very cool indeed
Ive moved away from scratch to use some more powerful engines but I still love coming here and learning the creative solutions you came up with to get past what I thought were the limitations of scratch. Keep up the great work!
3D raycast with multi layering would be amazing for next tutorial, It would be hard to do for beginners,But you really know how to explain and make it look simple
This is even better than part 9 of the tile scrolling platformer. You actually get to learn something here and how to code this for enemy AI games instead of copying code because after a few parts of a project you start to not care so much about the code and only about the final product.
In the tile scrolling platformer, if you just copy the scripts, it's your own fault. Next time, before you do, try to understand what's happening, and teach yourself how it works.
@@trombone28 I'm saying that I try to learn something and I copy what griffpatch does. I understand what he's doing but I don't understand how the code does that sometimes. For example, part 6.
@@RedToilets I see. What you should do then is try to break apart the code into smaller pieces, and watch the video bit by bit to try and better understand how everything works together, but I get your point.
This is why I don’t go to other RUclips channels for scratch tutorials because they most likely don’t work or outdated. Go to the king, he can teach you.
This is amazing! Griffpatch, please know how incredible your projects are, but also these video contributions to the community. I teach computer programming, and I often use Scratch for many of my students. These tutorials help me teach students some really cool tricks.
I'm reaching the 300 clone limit before it can find scratch cat at 6:36 edit: i fixed it, the problem was it was overlapping clones in top of each over quickly going to the clone limit
I personally don't use scratch, but this tutorial is still an amazing breakdown of how to set up a good pathfinding system. This video perfectly breaks down the essentials of pathfinding and make it easy to understand. Good job!
Just wanted to thank Griffpatch for getting me into coding. Two years ago, I stumbled upon Scratch and signed up for it. I began watching your videos and now I have a job for coding. I start tomorrow. This will be my first job at the age of fifteen. Without Griffpatch, I don't think I would've ever picked up an interest in coding.
Another trick to hide sprites while maintaining the collisions: set ghost effect to 100. Btw, this pathfinding (or light flow ;D) method is called flood fill, right?
0:23 Paper Minecraft and the pathfinder are linked because they share a filling algorithm. In the game, the light source will have a "infected" tile with a light value of 5 or something. Then that tile will infect other tiles around it and subtract 1 from the parent.
Griffpatch, is there a thumbnail glitch on scratch for you? (When you want to save the thumbnail as something but it doesn't save.) Its happening for me :(
Im making a fnaf arcade game, where you play as purple guy on a 2d screen while freddy, bonnie, chica and foxy are chasing you, this was REALLY usefull
Good, now do one that will handle diagonals and multiple walled routes using a grid of squares a certain size (to make it simple, because I have no idea how I'll program circular walls) and a character with some circular/ -elliptic*- hitbox and some velocity. Which doesn't rely on processor-draining Scratch-only features, but rather on maths so I can replicate it in any programming language I want. (saw this kind of pathfinding in an unreal engine game) *Actually I think a turning character with multiple dimensions would be unnecessary. Also it's no good if you love the comment and don't really do anything about it soooooooyeah -imanidiot-
Hey if you can reply to me please do cause I copied the draggable apple script entirely but it is still not working :( it is only working once I place the apple back down if I drag it in mid air the arrows are staying the same
Thank you for helping me and many others understand complicated ideas with your help full videos! It really helps me and I encourage you to keep doing so, and Scratch on!
I'm pretty amazed by the way color detection is used. Also I learned that scaling down an offscreen object wouldn't make him go onscreen again. Very smart design, even though it might create a bit too much lag in a larger scale project because of the clones being used. Also, I think you could make arrows invisible by just making them ghost 100, color detection would still work.
Awesome video! Did not expect this type of video since i consider pathfinding being advanced. I like how simple and short the solution was, but i would not have found it myself. This was some sort of reverse flood fill?
I remember playing your projects roughly 6-7 years ago back when i used scratch (the golden days). Was just taken back to this by nostalgia. So glad to see youre teaching a new generation of scratchers how to block code. Godspeed
17:18 I had a bug in my code that made everything move like a escalator lol 18:41 it looks like the apple is eating the cats in stead of the cats eating the apple
A few notes: 1. The path's up and down names are reversed, however this is visual. 2. Moving the paths will result in the pathfinders to stop pathfinding. This is hidden by deleting the pathfinders, but it can cause problems for anyone importing it into a game of theirs.
One little question: Actually i am working on a "open world" game. That means i have a Player always in the center and by clicking the keys i only change a "x" and "y" variable that moves other projects except my player. How can i add a pathfinding function for something enemies? Thats quite a bit more difficult... Thanks for this tutorial 😁
You should put the word "Scratch" in the titles of your tutorials more often, as doing so will give your videos a higher chance to get recommended to people that watch other Scratch videos.
Question: Can this be reused for the tile scrolling platformer? I want to add some sort of flying enemy but It's hard to add the collisions and make the enemy not get stuck on walls Or at least to be able to edit this code to work with the tiles in the other program
My one wasn't working at the start and I figured out the problem. The problem was that my clones were going underneath eachother, quickly exceeding the clone limit. I fixed this my making it place a clone if not touching edge or color purple (which was the color of my arrow)

It's similar to the flood fill yes, just not quite as optimized as floodfill doesn't care the order of search so can be made a little faster.
