Java Game Programming - Develop a Brick Breaker Game

Subscribe to my other channel for updated videos on TECH and PROGRAMMING:

Practice Recursion Problems in JAVA:

Java game programming is really easy to learn. We will develop a brick breaker game with java. We will use JFrame and JPanel for drawing different graphics to make this game work perfectly.

For beginners like me who don't understand the logic easily, your videos have always encouraged me and made it fun! looking forward to many more tutorials. thankyou :))

Just wanted to let you know that you just got me a 95% on my final computer science summative which brought my failing mark to a passing mark which allowed me to graduate highschool ! thank you!

You can change the starting direction of the ball so you arent playing the same game over and over by changing the ballxdir to a random number within small range

Random random = new Random();
int n = random.nextInt(2+1-2) - 2;
private int ballXDir = n;
private int ballYDir = -2;

you can adjust the range of the random for +speed/+difficulty. Make sure to change it in the ENTER key event also.

After 6 months of classes in text and math based Java, this was my first graphics based Java and I LOVED IT!! Thank you SO MUCH!!

For people that have problems when its not drawing anything do this:
put your obj.setVisible(true); after obj.add(gamePlay); This will make it visible after the objects are drawn, I don't know why it matters though but it fixed it for me

[ayub]

okay, so I've completed this tutorial. glad to say this was my first game program. Here are some troubles I encountered:
1.Wrong signs - Mostly < & > were misplaced [Syntax Error]
2.Game restarts with any key press once the ball goes off-screen.

I'm new to coding and would really like to step forward. Thank you very much, Awais for this tutorial.

At 23:26, don't forget to add
obj.addKeyListener(gamePlay)
after
obj.add(gamePlay) in your Main class to get your paddles to move.

Thank you so much for taking the time and effort to produce and share such an informative, insightful, and helpful video!!!

I have made this Brick Breaker game in just 2 hours and 15 minutes it's working properly like yours.This is my first game ever that is in java language and I learned a lot from your video.Thanks🙂

Here is the code:

obj.setResizable(false);
obj.setVisible(true);

obj.add(gameplay);

[adamh]

Thanks a lot for this tutorial. Everything runs great on my end and i changed some minor things on my end like making the bricks and paddle "3d" and adding a pic as custom background :)

[zsoldosbotond]

It tooks 7 hours to make this game after your tutorial, but I learned very much from it. Thank you!

[CarlosRamirez-jvnc]

I like how you explain, cause you go step by step. first time using swing and JFrame and totaly understood.

[panagiotiskoligas]

dear Awais Mirza, i am from Greece.thank you very much for this video.it really helped me a lot.but i built this game with netbeans and i must inform you that you must write the command:timer.start(); into all the functions you have created and implement the keylistener and the actionlistener otherwise the game will not be started!!!take care.thanks again!!!

[jumperlt]

Thanks, really helpful video, made me understand how timer, update and render works. Apart from the "physics", did all those changes between states and other things by myself. I think this video helped understand the basic game-makery and will lead me forwards to more advanced gaming stuff. Now I'm looking forward to upgrade the game and add tons of functions, levels, maps and so on. Thanks!

[khubinomhki]

This took me almost 4 hours to finish but I love the end product. Thanks for this tutorial:)

[mehmedcavas]

best Java channel. solve problems and videos to make games where u explain what u do. best man <3

[_vasu]

Great Video for beginners😊.You have taught in a well mannered and easy way.My game ran succesfully.Thanks a lot.

[neko_senpaianimeamvedits]

It took me 2days to completely understand and type it thank you. I wish i could show you how much i learned from this :)
