Super excited to see another tutorial! Your explanations are very clear and have helped me a lot. I only have a couple of videos left in the 2D tutorial and I'm looking forward to tackling this one when I'm ready.
This looks way more fun than using a Game Engine. And not only that its more fun, but its a great way to learn more cause its so challenging ! Amazing work Ryi .
Thank-you so much for the tutorial! It's always so cool to see how people handle these kinds of projects differently and your take was very simple and straight-to-the-point, which I find to be one of the best things about your channel! I can't wait to see what else you have planned in the future and wish the best of luck to you!
Thank you so much for this video. You've inspired me to study programming on my own. I don't know if I ever make a career out of it, but I really like it as a hobby :) Keep up the good work, RyiSnow!
this tutorial is great, i followed it the whole way through besides some of my own design changes for a school project. Ive learnt so much more than i would if i tried to make my own original game
this is really awesome. Just finished following this over 2 days (!) I have found this really good in writing my own projects using your code as a template for how to do things the right way! Many thanks - I look forward to seeing more excellent content.

I have been very excited for this since I saw tweet about the tutorial. It's always exciting to see an upload from you!! I learned so much from your videos 💕
I finally finished this tutorial, the end result looks really cool! When testing the Sound class at about 1:26:12 I kept getting a null pointer exception for the Clip object, which seemed to indicate the file paths for the wav files weren't being read correctly. After checking the Sound class for typos and not finding any, I eventually figured out that the res folder wasn't included as a resource in the project's build configuration by default. If anyone runs into this situation while using Eclipse, the steps I took to fix it are: 1. Right-click on your project in the Project Explorer and select "Properties" 2. Select "Java Build Path" from the menu on the left 3. Click "Add Folder", check the "res" folder in the window that pops up, hit OK, and then "Apply and Close". This allowed the res folder to be recognized, stopped the null pointer exception and now music & sound effects play perfectly. :) It's kind of weird because I've never had this issue before. I could always just create a folder, add the sound files and it would work without any extra steps just like it did in the tutorial. So maybe it had to do with me recently moving my projects around on my hard drive? I'm not sure. Anyway, thanks for another awesome tutorial, Ryi. I'd love to see more tutorials for classic games like this. I appreciate your hard work.
@RyiSnow OH woops, I thought I followed what you did at that timestamp exactly, but turns out that I selected "Folder" instead of "Source Folder". That explains it. 😄
PlayManager class 68 line: While the value is 7, Mino Z2 does not fall out, if you change it to 8, then everything works, since now we take into account 0 and count from 0, not from 1

I love your videos, and have been working on your 2D Game tutorial and want to make a video walking through it. What screen recording software do you use?
Man, i'm having a problem and I was wandering if you could help me. On the Auto drop step, when i put the "gp.launchgame" the mino simply disapears and I dont know why, can you help me?
Actually, you should put the "repaint" method outside that if. You should update in every possible moment, it's good to limitate the update but the render should be outside.
hey @ryiSnow. i've been following your code very carefully but at doing the auto drop part when i tried calling the gp.launchgame, i dont see any blocks falling but before i call the gp.launchgame its just floating and not moving just like yours.
Hey! I've ran into an issue, I tried adding a 1x1 mino, but it didnt work. I tried putting all 4 cubes in 1, but then the line breaker didn't work, then I tried just removing other 3 parts, but then it had some bugs. Could you please help me?
Love the tutorial so far! Quick question about the auto drop, I called launchGame in the main class and it seems to not be running after doing that as well. Was wondering if you have any thoughts as to why? Thank you and great content!
@@RyiSnow Yes I saw that my if statement in the game loop was not in the implementation of the while. Hence why it was not running. Thank you for responding!
Hello Ryisnow unfortunately I can't fix issue. I can't replace the current mino with next one. when Im writting if bottomCollision than else and autoDropCounter. but it does not work please check f you can: package Main; import java.awt.Color; import java.awt.Graphics2D; public class Mino {

Hey nice video !! I'm using your video for training my java haha. But i'm stock because I use intelij. Is someone here using intelij ? because at 5:29 you telling us to add unimplemented methods but can we do that on intelij ?
If it doesn't show up in your environment, you can manually type the run method. I just used the auto-fill function of Eclipse. I'm pretty sure IntelliJ also has a similar function though.
@@RyiSnow thank you :) but I have an other bug. I check all of my code but I dont found the bug... the left, top and right colision of the static mino's are OK But the left side have no colision.

Thank you so much for the video ❤❤ but the static boolean variables upPressed,downPressed... doesn't work in the class Mino(KeyHandler.upPressed...) please inform me to solve this problem
Hi Ryi, thank you very much for this video. I am having some trouble though when creating the first mino. When running the project, it returns the error: Exception in thread "main" java.lang.NullPointerException: Cannot assign field "x" because "this.b[0]" is null. Could anyone help me please?
At 22:02, when I type in Block.SIZE, it shows an error that it cannot find symbol variable for Block. In the mino class I did make it a public array, so not sure why its not finding the symbol. Otherwise, great video so far!
