How to Fix A Scratch Bug 🙃 - Classic Platformer Wall Jump

It's great to learn good coding techniques like this early on. Being disciplined to reproduce, document, and go back to test is key to successfully coding more difficult projects. One thing I'd add for new programmers: sometimes it's helpful on the REPRO step to figure out the SIMPLEST way to reproduce the bug to avoid any other variables that might make it hard to squash. In this case, you can reproduce the wall slide bug almost anywhere. But imagine it was deep in the game somewhere, making it hard to quickly get there and test. In a case like that, I would recommend creating a new level where you can reproduce the bug easily right at the start. It will make your debugging faster because you can run test more quickly. And sometimes just making it simpler actually helps you figure out what's going wrong.

7:09 wow I love the effect that was created with the "scratch effets that pops" tutorial 🤩

Amazing step-by-step tutorial!! This is very useful for anyone trying to fix bugs, in Scratch, and other programming languages!

Griffpatch you are my favorite scratcher! Any tutorial with you calms me down and makes me scratch even more! Keep scratching and do whatever tutorial you ever want! :)

TYSM Griffpatch, This is very useful for anyone trying to fix bugs, in Scratch. :) you are amazing!

Griffpatch is way better than other tutorials for this reason: He actually explains concepts and bugs, why they happen, and how to fix them! Other tutorials are just: Please copy block by block, which isn't very useful when you want to add the concepts into another project!

Another tip: you don’t have to fix all bugs, you can if you want to, and it is good to at least understand why they happen, but if it doesn’t affect the average playthrough, it should be fine to leave in. For example, if there is a really hard glitch that can only be done on one or two levels, it should be fine to leave in, as it won’t be disrupting anyone’s gameplay. But if the glitch regularly causes things that should work not to work, it should definitely be fixed.

ok so is it me or is his drawing's are just so cool like how do you make scratch cat into a whole spider! its terrifying and very creative

Griffpatch your tutorials always makes my day better 😃

I did not even know about the bug. I did want to add moving platforms; so lovely you are covering that, hopefully, you also cover how to add more levels into the game like level 1, level 2, etc.

Wow! This helped me a lot! I used the same steps fix a bug I was trying to fix in my project! Keep up the great wok Griffpatch! :D

This is my fave video, I like these videos aka tourtials. it helps me improve in scratch, I alsways have bugs and stuff that a normal scratchers have, I knew this channel since 2019 (I think)!

OMG!!! griffpatch you did so well! I need thousand of years to do this!! Good job!! Keep going!!!!

I’ve had this so many times! So good to see a fix!

I have a bit of a compromise for leaving this bug in and making sure it doesn't impede on gameplay. For the IF statement you just added, put an or there and for the right side, put "Not pressing Z and X key" there. (Or whatever keys you want) Now, in order to trigger the bug, you need to press two keys together!

Great video! Congrats on 135k subs!

I'm about to end my membership (hopefully temporarily) for a while, but this looks AMAZING! Glad to support. ~ LaserCat

No One Can Teach Scratch Better Than Him. Love Your Videos ♥️

I hope he makes an episode 14 on removing the enemy sprites when we squish them and not reappearing when we go to a different Scene and back. I just feel like using the technique we did for the collectables. Using a Null room but if Griffpatch can make a new way, that would be nice.
