[@belalehner3937]

Your code is great, but i have a suggestion. At 9:12 You define and initialize the GAME_UNIT final constans, which later creates a huge and unnecessary X[] and y[] coordinate arrays. I would rather write this: _static final int GAME_UNITS = (SCREEN_WIDTH * SCREEN_HEIGHT) / _*_*(UNIT_SIZE*UNIT_SIZE); // 576_** In this case the x[] and y[] arrays will be at size 576 which equals 24x24, and in this case this is the exact size of the the game field. After that I would initialize the arrays like this: final int x[] = new int[GAME_UNITS / (SCREEN_WIDTH / UNIT_SIZE)]; which will give you an array with 24 elements. *This way You will save some memory.*

[@Dartanghan]

ı think it could be like this for x SCREEN_WIDTH/UNIT_SIZE = 600/25 =24 for y screenHeight/ unitSize =600/25 =24

[@Dartanghan]

@@belalehner3937 bro btw i didnot get the move method of the snake especcially first part x[i] = x[i-1] , y[i] = y [i-1] part like what does that mean? Howbit makes it move to the right? I dont understand

[@moshezechariah3705]

No, x[0] y[0] is referring to the head of the snake because this is the first segment until ... x[6] y[6] which is the last segment of the snake body at first. So , in this loop, the sixth body segment which is the last body segment gets the position of the fifth body segment, so it moves right. The same about the fifth segment which gets the coordinates of the fourth coordinates, and so on until you get into the head. So in this way, you shift the snake body including the head to the right.

[@Dartanghan]

@@moshezechariah3705 i think if snakehead doesnot move body doesnot move either

[@moshezechariah3705]

@@Dartanghan you're wrong because there's a switch statement after that loop which moves the head separately opposed to the rest of the body segments. It means, that if you for example moves the snake down, all the body segments follow each other until they reach the head - this is the loop After that begins the switch statement which gets the input 'D' so the snake head moves down , and all the body segment follow it when the loop begins again

Great tutorial, I just started learning Java and had no idea it was so powerful. I did some C++ and it seemed I needed a 3rd party framework for everything, but Java has native libraries for just about everything it seems. All the different classes/interfaces and functions/methods are difficult to keep up with but this video is helping a beginner like me become more familiar.

[@keanjaycox7959]

Hey fantastic tutorial, thank you! One thing I noticed that is off a bit, the checkCollisions() is off by one UNIT_SIZE on the right and bottom, so you can actually go slightly off the screen on those sides. I just subtracted UNIT_SIZE to fix this. if(x[0] > SCREEN_WIDTH-UNIT_SIZE) { running = false; } & if(y[0] > SCREEN_HEIGHT-UNIT_SIZE) { running = false; } Can't wait to dig into more of your videos, thanks again!

There's a bug in the checkCollision() method for right border and bottom border that lets you go through the screen that can be solved by adding an " = " after ">" sign or by substracting 1 "UNIT_SIZE": 1. By adding "=" //Checks if head touches right border. if (x[0] >= SCREEN_WIDTH) { running = false; //Checks if head touches bottom border. if (y[0] >= SCREEN_HEIGHT){ running = false; 2. By substracting "UNIT_SIZE" //Checks if head touches right border. if (x[0] > SCREEN_WIDTH - UNIT_SIZE) { running = false; //Checks if head touches bottom border. if (y[0] > SCREEN_HEIGHT - UNIT_SIZE){ running = false;

First of all I really loved your tutorial! You've made OOP look very simple. However I encountered a problem within this game when I wrote in C for just console. In your code you just check if the head coordinate of the snake matches that of the apple and if it is true the coordinates of the apple exist anywhere outside of the head. Yet as I clearly notice at 40:51 the apple doesn't show up in the canvas, which means that the apple is inside the snake's body. Your code doesn't check if the apple's coordinates match the coordinates of the body hence causing the apple to appear inside the body. So the same problem bothered me in C too and I tried to write an algorithm to figure it out. Once I'm sure my algorithm works properly, I'll post it here. Hope I didn't miss anything in the algorithm. Keep doing this great job bro. Thank you a lot. Loved it!

The only malfunction I came across occurs if, for example, the snake is going downward with its head not near any of its body "segments" (except "segment" # 1 of course) or, for the sake of clarity, with its entire body vertical in the game window and I rapidly press the left arrow followed by the up arrow, the game is over as the snake's head winds up colliding with its first body "segment". The snake's head doesn't make it one UNIT_SIZE distance to the left since the "up" directional change command is being issued so quickly right after the "left" directional change command. And, since the snake is technically not going downward anymore, it is allowed to move upward and thus end up colliding with itself (its first body "segment"). Apparently, the snake's directional changes are being processed faster than the changes to the x and y coordinates of all its body parts when the directional keys are pressed in rapid succession. Is there a remedy for this?

[@MrPaulOMalley]

Eureka! I found a solution to the problem I previously mentioned. In the method public void keyPressed(KeyEvent e), I added an extra conditional statement to each case of the switch (e.getKeyCode()) block. The code is the following now for me in GamePanel.java: { case KeyEvent.VK_LEFT: if ((direction != 'R') && (Y[0] != Y[1])) direction = 'L'; break; case KeyEvent.VK_RIGHT: if ((direction != 'L') && (Y[0] != Y[1])) direction = 'R'; break; case KeyEvent.VK_UP: if ((direction != 'D') && (X[0] != X[1])) direction = 'U'; break; case KeyEvent.VK_DOWN: if ((direction != 'U') && (X[0] != X[1])) direction = 'D'; break; } These x and y coordinate conditional requirements for the head and the first body "segment" of the snake prevent any instantaneous 180-degree direction changes from rapidly pressing, for example, the left-arrow key followed by the up-arrow key (pressing one immediately after the other) when the snake is traveling downward as I described in my previous reply. An instantaneous 180-degree direction change involves the snake's head not moving leftward first before moving upward when the up-arrow key is pressed immediately after the left-arrow key. Problem solved.

you could build in a delay so that after every key press you will have to wait for example .5 sec until the next key press is registrated

[@MrPaulOMalley]

@@elidegen2000 As you can see from my reply to my own comment, I concocted a solution that works flawlessly. However, I am interested in your delay solution since it is the more practical solution in other keyboard interface design implementations. I've tried putting a delay in via "try {Thread.sleep(600);} catch (InterruptedException ex) {Thread.currentThread().interrupt();}, but this only results in pausing the running of the program by 600 milliseconds. I get a pause in the snake's movement lasting .6 seconds, not a delay in getting the next keyboard press, which is what we want. Do you know where to place the delay in the Java code for the desired effect, that is, in which method?

@@MrPaulOMalley okay I don’t see your answer I’m sorry… unfortunately I’m a rookie so i don’t know either how to solve this… i also thought about trying with the sleep function but I don’t know any other solution

[@kemann3815]

Lovely. I was excited for this one since early on on the playlist and its great. Thats an interesting way of setting a 2d grid of blocks or places that the sprites can be placed in. I was wondering about making a gui library and a physics or game engine tho ... despite being a beginner lol reaching for the unreachable i guess ... but i learned that problems are actually good in coding because by the time you solve the issues, you understand the reasons behind it

[@ziskador]

I like that this isn't one of those videos where they explain what a variable is every time

[@mennaeldamaty5269]

Your tutorials are amazing, but I’m having an issue, when I run the program nothing appears, how can I solve this?

[@techdoge3625]

most likely you are forgetting to run the draw(); method in the paintComponent(Graphics g) method

[@fatimaadreeta]

That was super fun to watch! GUI is an absolute nightmare to me but definitely will try this.

[@husein_alfil]

Hello ! Thanks for the great Video ! Just one thing that didn't work for me and that, when I wrote the lines and created the Apple .. nothing showed up on the screen and it remained black .. nothing is added at all ! How to fix this ?

Im having the same problem

[@ChaperoneDad]

Great to get on board when I am a student and this has definitely helped me out with the methods and supers. Thanks Bro!

Neat project :D Hoping following along with many of these projects over the summer will help my mind absorb some of the info. Also this was a lowkey flex that you're just goated at snake, huh?

This video was fabulous, a simple and very detailed lesson, however I would like to know how I could do to make a little system that resets the game, in a KeyPresser, I tried several ways and none worked as expected, I don't care idea how to reset snake pro values ​​0, 0 again. Could you please advise me on how to do this?

Really struggling lately. I wish I knew how to even think of what I would need when creating a simple game like this. I'm starting to feel like a hopeless idiot.

[@gursevaksingh2504]

Thank you for the tutorial. Can you or anyone else please explain how x[] and y[] array are getting initial values, i.e how it get to know the coordiates?

[@TainDK]

i dont know this - but my guess is that it is part of the import settings (at the very top you have the imports =)

[@yonasghirmay6473]

By default the initial value is zero

This is really a good game... where I learned lot of graphics... Thank you buddy......

[@justprem4215]

So I'm learning Java for the first time, and I was curious, what calls the draw and paintComponent methods? is it that the JPanel finds them automatically and calls them from its class?

[@fabianzbranski2061]

So actually time.start() calls all his actions listeners every 75 mili seconds (cause of line timer = new Timer(DELAY,this); and all the actions listeners here are public void actionPerformed(ActionEvent e) and public void keyPressed(KeyEvent e)

This was amazing. I'm going to add new features and improve others. For instance, increase the speed of the snake, add a Restart Game option, save the highest scores, and add your initials to the saved scores.

[@genisys375]

I had two problems with the snake: Sometimes lag and sometimes it went off the edges. If someone has any of these problems, here is the solution. The lag I resolved adding this line in the main class before call GameFrame: System.setProperty("sun.java2d.opengl", "true"); The problem with edges I resolved modifing the next if conditions in the checkCollitions method: //Check if head touches right border if (x[0] > SCREEN_WIDTH - UNIT_SIZE) { running = false; } //Check if head touches bottom border if (y[0] > SCREEN_HEIGHT - UNIT_SIZE) { running = false; } I work on Linux and I use Apache Netbeans.
