Python Game Tutorial: Pong 

Me: *Gets a black box to appear on the screen* *Smiles Proudly*

Build a game, no matter how simple, always makes learning a new language more fun and motivating. Thank you!

This is my first-ever (finally) attempt at coding something in Python. After dozens of "learn python in x-hours" videos, I finally realized I needed a specific goal, and pong was recommended. I had to pause at 32min to just play my pong game, with the biggest grin on my face. Thanks so much for this tutorial, it's EXACTLY what I needed to finally jump into coding.

Me: copies everything he did but the color and size ratio's Also Me : i am programr

Do a beginners tutorial on how to program a game like "Fallout 4" using turtle in Python. It may need a few extra lines of code.

richards from silicon valley was right, spaces are annoying just use tabs

I watched the whole 44min and I was not bored a second. I loved it, thanks for the great tutorial, please make more!

Thank you so much for taking time aside to help people code, coding can be very hard without basic information, and what you do so helpful, please keep uploading. (Sorry for the grammar mistakes, English isn't my native language)

Thanks so much for this. I am super new to coding and found this and decided to give it a try. I still have a long way to go, but I’m having fun. I hope to learn more with your videos and free code camp soon.

This is the best tutorial about a project in python. Thanks so so so much!

Finished. I never thought I could code a game until I watched this video. Thank you, Christian!

Starting at 40:49, the sound comes after the ball hits the coordinates because that is where it is placed in the program. If you move the sound to right after the if statement, it will occur in the correct order hit-sound-rebound. I do not have Python and have never programmed in it but I used to be a Visual Basic programmer years ago (VB 6). Now I am a sys admin. I kind of miss programming. I followed the logic perfectly in this video despite that fact. I believe I will try it now that I have watched this. Thank you! This is awesome! It reminded me how much fun programming was!

That was very helpful with my school project, thank you very much for the help.

Thank you very much for making this tutorial. I appreciate the hard work you put into this bro! Everything worked perfectly ;)

31:25 "I just call it a pen, but it's actually just a turtle" - Smart computer man, 2020

Thanks for this awesome tutorial! The game is working great for me (I just needed to change the ball.dx and ball.dy to 0.2 and -0.2 respectively). I'm going to try and make another game using the turtle module and the techniques I learned in this video.

instead of ball.shape("square"), do ball.shape("circle")

24:35 why is there a 10px offset that causes the ball to go off the screen instead of stopping at the window corner?

Thank you! Great tutorial! Very good style. It is fun to watch! So professional, so inspiring!👍

Really good video! I was really happy with how it turned out! I made some adjustments so they paddles didn't go off screen, but the explanation was so well made!

I think adding the ampersand (&) at end of the file tells to run the command in the background for unix-based systems.

Thank you for the tutorial. it was mind blowing.

Short and to the point. Well done.

no one could have made it any easier and motivating, thank you

Hello, I followed through the whole tutorial and now at the end I'm trying to make a timer for the game. I successfully made the timer just how I wanted but it froze everything else in the game. I'm pretty sure the problem is that the loop is waiting for the timer to finish until it goes again, but I want the game and timer to run simultaneously. Any ideas?

@ 23:50 instead of sending the ball to 0,0 when it collides with the x boundaries, i used: ball.goto(390,ball.ycor()) and ball.goto(-390,ball.ycor()) This is preserving continuity of the game, instead of directly sending the ball at center.

Thank you for this great tutorial! If someone wants to limit paddles movement in y direction you can do this: def paddle_a_up(): y = paddle_a.ycor() if y < 250: y += 20 paddle_a.sety(y) def paddle_a_down(): y = paddle_a.ycor() if y > -250: y -= 20 paddle_a.sety(y)

This was great!!I had to figure out how to show the turtle window and stuff on windows because the way visual studios was set up. I didn’t add sounds because I didn’t want to mess anything up and I didn’t want to spend any more time. Great tutorial!!!

this is probably the best coding tutorial i have watched so far. He explains everything super well for those who have never used turtle before. He simplifies everything and takes his time instead of speeding through it. I really want to see a snake game tutorial by this guy but I hope he teaches us how to make a grid instead of just a dark backround because a grid looks much better and makes it easier to play the game

Yo my dudes, loving this channels 'simple' yet effective tutorials, thank you so much! Having alot of fun here :) Edit: Helps that you guys dont rush things and like to recap before moving onto next!

Thank you for this practical presentation. Explained alot for me man. Appreciated

Great tutorial. Got the sound working in windows and now I just need to figure out how to make the paddles get continuous input from a held down key and make it faster/smoother. Learned a lot. Thanks!

im having problems every time i try to run it, it says in the terminal invlid syntax

Great tutorial, I was wanting to make a more interesting version of pong and using this a base. How would you suggest dynamically updating the background as the game runs?

way more useful than my teacher, learned more here than I have this month

Great tutorial, easy understandeble and good explaining on what does what, so oneself can improve a bit on the programming like not make the bat go off screen and whatever comes to mind :)

print("The only winning move is not to play.")

Thanks I love this without class and difficult code its perfect !

Great video for beginners in python (like me) to learn a simple yet interesting game! I did it on windows and followed this video step by step pretty much and everything works perfectly. I was using python 2 and had to take away a bracket and add a colon on the 'if ' function in 'paddle and ball collisions". Overall amazing Video. :)

For paddle and ball collisions I used absolute value function for the distance between the core of the ball and paddle, it's easier and doesn't cause the ball to stuck behind the paddle.

I don't know why I was so happy when the black square appeared on my screen

A cool little thing you can add to the code as well is a direction randomizer every time the ball is in the center by importing "random" and then adding something like this: if ball.xcor() == 0 and ball.ycor() == 0: firstDirection = random.randint(0,3) if firstDirection == 1: ball.dx *= -1 ball.dy *= 1 elif firstDirection == 2: ball.dx *= 1 ball.dy *= -1 elif firstDirection == 3: ball.dx *= -1 ball.dy *= -1 in the "#Move the ball" section of the while loop :)

Beautifully explained , step by step. Great tutorial. You sound so similar to Dr B Fraser who does You Tube tutorials on Android lists etc.

Which text editor he is using?

Having issues with sound on Windows, Whenever it touches the wall or the paddle it gives a Windows error sound instead of the bounce sound that I had downloaded

I made it... in 2 hours, but its awesome. Thx for all the wisdom hehe

This one works fine. I have tried executing other game codes in RU-vid, it did not work. Awesome tutorial.

having issues with sound on windows and the ball is just to fast for the paddle or whatever to keep up, what can I do to fix this.

Just wondering... why do you like using 4 spaces instead of a tab? I have always used tab and the computer automatically puts a tab in certain situations, so why change it up?

9:37 I have never seen someone need more effort to write the word Function. Overall a great video for beginners

Building a Pong game This does put a smile on my face

you should explain that if ball.dx is set too high at 2 use fractions your code should look like this : ball.dx = 1/5 ball.dy = 1/5 adjust bottom half of the fraction to your desired speed

This is a very good tutorial and I very recommend it. It was easy to understand and I might actually stand a chance at creating games in the future. After it finished, I managed to: Make it slowly get faster, make it so both players can create there own names and make the game a best of 5 where your paddle gets smaller for every point you get and it even comes up with text at the end saying who won. Thank you!

broooooo thank you soo much man i was scared that i would fail my test but you saved my 🥺

Very useful tutorial! Thank you very much from Hungary! 😊

Anyone who's built and run this, does the "spin" of the ball change depending on the velocity and placement of the paddles when the ball hits?

Thank you for a great tutorial! So, how do I export this as a finished .exe game?

thank you so much. this has helped a lot and was very fun

was fun to do this thanks man

hey i got a problem where my ball speed isnt constant even though i have the same exact code as the tutorial, anyone know how to fix this ?

hey I'm facing a bug, do you mind helping me out on this, "whenever the ball bounces from the corners it's speed increases for a fraction of time, and gets shot in the direction it's following... "

im trying to get the ball to move but an error pops up saying the ball is not defined even though im following along exactly

I come from java and I'm shocked because of the simplicity of py. I began to study Python few days ago and I love it

my ball has different speeds, i dont know why, how do i solve it? the best speed on my computer is 0.13

thank you for the tutorial!

YOU ARE AMAZING AND YOUR EXPLANATION LEVEL IS TOP NOTCH!! VERY NICE VIDEO

I can't believe I just programed a game, thank you

So, I was having trouble with the paddles not showing up and I moved the following code, [while True wn.update] after the paddle codes and then it started working!

Thank you for the tutorial. I found it very useful. I have a question though, when I try to move both paddles at the same time (giving the program two inputs simultaneously) the program gives priority to first input given. Is there any way to fix this? Or this is because the turtle library? I am saying this because in some games, mario for instance, you can jump but you can also jump to left or right by pushing 2 buttons at the same time. Thanks in advance.

please help! in the main game loop, where we try to get the ball to move, i keep getting an error that says "instance of turtle has no 'dx' or 'dy' member." How do I fix this???

Thank you very much sir............that helped me to create my own pong game...☺☺

so i tried to do the sound part but instead of the bounce.wav playing, i just got a windows error sound, which is just as good so im happy

im pretty sure i copied the code correctly but the paddles can go off screen, did i do something wrong or did he not code that part?

thank u so much... your video tutorials are the best on youtube!!!! Love your Hard work....

Ahh finally I'm done Christian: *AaAAaanDd*

For windows you have to do winsound.Beep(800, 75) (you can change the numbers if you want you should end up with this import winsound winsound.Beep(800, 75) Edit: Only if the first method doesn't work

i dont know if i missed it, but if you wanna end the game you can do something like this at the end of it all under the while True loop. # game over if score_a == 5: pen.clear() ball.dx = 0 ball.dy = 0 ball.goto(0, 0) pen.write("Player A wins!!!", align="center", font=("courier", 32, "normal")) if score_b == 5: pen.clear() ball.dx = 0 ball.dy = 0 ball.goto(0, 0) pen.write("Player B wins!!!", align="center", font=("courier", 32, "normal"))

28:00 the giant if statement should be nested if statements, since they are a lot more readable and noob friendly

Great tut. I've been trying to improve the game by adding ball speed-up after every paddle hit but i cannot figure it out :/ Can someone help ?

Great tutorial! Only issue I'm having is with the 'w' key. I can't hold it down and continue to move up like I can with the other keys. Anyone else having this issue?

i was so happy when u said u werent using OOP, i cant get my head around it!

Thanks so much this was so fun :D

"raw_input" is not defined. Me: Well, that's because there is no "raw_input" in my code

Im running this code in visual studio code on windows 10, everything works but the ball goes way too fast?

for the sound part what is it on windows?

When I press and hold the keys that trigger the movement, they do the movement repeatedly as long as I'm holding the key, which is what I expect but, I don't know why, if I press and hold the key that triggers the down movement on the paddle b, it only does it one time. It's not a keyboard problem if anyone's wondering

The ball keeps changing speed... please help

Dude my ball speed at the game is really high.. After doing the same as u did.. How can i reduce it.. And keep it to a normal

Amazing tutorial, thank you very much for your time.

Don’t use spaces. Set your visual studio code text editor to use tabs ( seen in the bottom right corner of screen “Spaces”)

Personal Time stamp, please ignore. 19:55

28:49 my ball trespasses the paddle b :(

That helped me alot to understand more of python programming thank you very much

Wow! You are really crystallizing many concepts of my early studies of python. I will watch more.

love code first

how to make pads smooth as the ball Can anyone please give a suggestion

this is awesome. thank you sir

Hello, enjoying the tutorial so far but came across a problem where I tested the paddles and ball after programming and they wouldn’t appear! I doubled checked all the code and no syntax errors. They were just invisible, please help me with this issue soon and I would love to make this game and learn how to program
