[@hansmalm2801]

This is just perfect videos for beginners that have learned the lauguage and how it works but needs to see how you use the code in easy small programs. There are tons of "learn how to program"-videos but with no usable examples. That is just like learning some chord on the guitar but no song to play. YT needs a lot more songs to play, like this. You also have a perfect voice for this and no messing around with side tracks. This is the equalivent to BASIC programs that you could find in paper magazines in the 80s. Just perfect! Keep them coming. Thank you.

[@BabyBunny-Cottontail]

I'm so grateful for your videos! It's so much more fun learning Java when there's some GUI and fun games your working with. I've been slowly learning Java for the past year now, but it's all CLI apps in every tutorial. I'm following your tutorial now and I'm learning so much from them, but I know I'll be coming back in a couple of month and do them all over again when I know even more and probably understand even more of all the things your doing. I just wish you could explain even more of what your doing and why. For an example: why do you need to add "true" at the end when you're changing the tiles for the snake and the food from 2D to 3D? Keep up the good work and I promise to recommend this channel to all my classmates (I'm currently studying QA-testing and were using Java)

[@KennyYipCoding]

I try not to overexplain sometimes so i might not explain 1-2 parameters, but on some IDEs (or if you use vscode), hovering over the function will tell you what the params mean. Basically the boolean value for 3D indicates whether it should be 3D raised or etched. Meaning, should it look like the top of a cube (true), or should it look like a cube shape hole in the ground (false).

[@dovydasbalciunas5002]

May I ask how did you learn to code? Did you learn by creating games?@@KennyYipCoding

[@dovydasbalciunas5002]

How are you doing in learning Java?

[@KennyYipCoding]

@@dovydasbalciunas5002 yes! so people focus too much on syntax and "correctness", instead it is better to learn by building projects :) So I can pretty much code 2D games in any programming language because I understand the concepts, even if I'm not an expert on said language.

[@RachaitaBhattacharjee]

In 27:53 the green dot is not moving. What to do?

[@KennyYipCoding]

go back a few minutes, you most likely missed a step Did you setFocusable and addKeyListener in the constructor? Did you add requestFocus in app.java? Have you updated the x and y positions of the snake when a key is pressed? Either the key presses are not being detected OR they are being detected but nothing happens. It would help to add debugging print statements

[@RachaitaBhattacharjee]

​@@KennyYipCoding how do I add the debugging print statements?

[@jorgerivera3733]

I get a bug on line #22 "Tile" snakeHead variable. I only get the "TIle" as abc **Resolved. The class path was misspelled.

[@DuB_2k]

The grid isn't showing up. There are no errors as the program runs. I'm not sure if its because im on a mac and hes using windows but the program produces nothing when I run it.

[@cubes709]

same im on mac too grid dont work

[@cubes709]

just before you add the lines add a g.setColor(Color.white); it worked for me

[@noahfeazell3336]

Question: Why do you need to declare all the stuff for the frame. and then declare stuff again in another class so it can be drawn on?

[@TheBestCats-l3w]

Amazing Tysm I’m making this tm can’t wait 😊

[@hyf1099]

Tks for the video, but I get bug: when i press left down right sequence fastly, game over. Can u fix that, it happen when score is greater than two

[@robtai6225]

can you build a platformer game in java?

[@tonyguerra136]

Hello Kenny, I am wondering why when I type in line #9.....frame.setVisible (true); and line #11....frame.setsetLocationRelativeTo(null); a "b:" and a "c:" are added automatically to the "true" and "null" like (b:true) and (c:null). Is it there an "auto-correction command" in the VS that I can deselect? Wonderful videos and thanks for teaching me VS and Java.

[@KennyYipCoding]

I think you might be referring to the parameter help box. kzbin.info/www/bejne/eHOTmI18pdqegLcsi=W-lNBaE7m-T-l-cT In my pinned comment for the how to set up java in vs code video, you will find instructions on how to disable this feature

Does this code work on BlueJ too?

[@stevensaleh4263]

Thank you so much bro finally i made snake game 😊❤

[@kartikkakkar9410]

what if I want to change just the color of the snake head? how can I do that?

[@KennyYipCoding]

Let’s say you want to change it to blue. Set the color of g to blue right before drawing the snake head. Then right before drawing the snake body parts, ser the color of g to green

[@SiddhantShedge]

Just did the project and it did help me clear my java fundamentals!I just had one idea,how can I increase the speed of the snake each time it eats the food?

[@ronin6397]

Hmm looks complicated.. The speed increases with a lower level of the Timer. Maybe you can use and adapt to the same system as the velocity.

[@SiddhantShedge]

@@ronin6397 thanks for your suggestion!

[@devincaruso8128]

This seems like a really cool video! I'm new to programming and often don't know what I'm doing, but I'm trying to copy the code down, and I get the error: package javax.swing does not exist(compiler.err.doesnt.exist) after typing import javax.swing.*; I have the java extension pack and a JDK that works for other programs, but not here. Does anyone know what might be happening? Thanks!

First of all thank you very much for this tutorial! Apreciate it! I have a dual boot machine, I tried this tutorial first on Ubuntu and it didn't work, it didn't open the window when I executed the program on 3:44, then I switched to windows 10 and it worked fine. Do you think is there something wrong with my machine or with how I installed java on Ubuntu? Or does this code doesn't work on Ubuntu?

[@nehemiahpaulpichay23]

Is there any idea how can I put a button that says "Start Over" and the game resets from the start again. When u lose, u have to close and run it again, wonder how can I do that, beginner btw peace.

[@KennyYipCoding]

Doing it with a button is unnecessary, you can add a check for a key in the key pressed function, and check if gameOver, if so, flip gameOver back to false and reset variables back to starting state. Ex) set score back to 0, clear the snake body parts array, place the food randomly.

Yes but it is very unlikely to collide with the snake’s head given the total number of square available.

[@Kanha0321]

I have made something similar too can I share its link?

[@Sweet_Solos]

That was very good tutorial i learned alot by following along and tweaking! I just have a quick observation regarding the draw(Graphics g) function you created for both the snake and the food graphics. Coming from JS i find it so odd the behavior of both the .setcolor and .fillRect methods, because at first I was so confused of how these methods were targeting the desired tiles but then i figured it out after reading the docs, apparently all subsequent graphics after .setColor will be drawn with said color until specified otherwise. It just seems unecessaribly verbose if I wanted to generate a more complex pattern but i guess thats just Java.

[@KennyYipCoding]

Yes you can think of setColor as pinking a color pencil, and you only switch colors after calling setColor (picking another pencil) again! I also have a snake tutorial in JS if you want to see how it’s done in JS

u just have to make one in the keyPressed function. Here is a code just paste it in there: if (e.getKeyCode() == KeyEvent.VK_SPACE){ snakeHead = new Tile(5, 5); snakeBody = new ArrayList(); placeApple(); velocityX = 0; velocityY = 0; gameOver = false; }

I can´t run the code,I think it´s because the javax.swing feature is not working, but I´ve written it exactly how you did, so I am confused a little bit. Sorry if there is a mistake on my side, but I´d be really happy if you could help me with that. I set up Java in vscode like you in your tutorial, but I could´ve done a mistake, so I please help me if you can. Also thank xou for creating videos like this.

nice video. if it bothers you that the snake goes in with and and one more body tile in the boarder and doesn't die, just do - 1 at the boardWith and boardHeight like this: if (snakeHead.x*tileSize < 0 || snakeHead.x*tileSize > boardWidth - 1|| snakeHead.y*tileSize < 0 || snakeHead.y*tileSize > boardHeight - 1){ gameOver = true; }
