C++ Tutorial 21 - Simple Pong Game (Part 1)

[@DerMeteor1324]

You make great and nice tutorials. I finally found a KZbinr that shows me how to program in C++. I just wanted to say thanks to you. Keep going with this!!

[@hellomynameisorange2860]

Thanks dude! I love your tutorials, you've gotten me into C++.

[@ElderMoro]

This guy is freakin amazing.

[@karshtharyani4253]

The random direction won’t change unless you add randomise() to the code, right? That’s why you got 6 twice. When you re-ran the program you got a 5 because it was a new seed. Am I correct?

[@justanotherfangirl2398]

Just do #include time.h at the start then put srand(time(NULL)) above direction = (eDir)((rand() % 6) + 1);

[@justanotherfangirl2398]

except that goes into negatives wtf

[@anonymousmask3823]

I love creating games on c++ Thxx for all the videos

[@calvinmillett]

Hey, im having a problem when i try to build the program it gives me an error for the class cBall. The exact error is ( 'cBall::Move': non-standard syntax; use '&' to create a pointer to member )

[@viktornikolov1570]

I really like the opening to the video. Great content as well. I hope you will have some time to do more in the future. Cheers.

[@jorgeolguin3274]

how did i get negatives ex: ball [-1,-1][2] ? did i do it right ? it successfully built but i thought the numbers would only be 1-6?

[@farahhawani5530]

why my program didnt recognise eDir? is it in C++ coding or not?

[@farahhawani5530]

Puneet Verma okay thank you..!!

[@leenahjune]

I have a question..when i code direction =(eDir)((rand()%6)+1) It show error...compiler say 'rand' not declare in this scope

[@erlindamecate]

bro this helps my mom is impressed ty bro she proud of me

[@samuelshtefanio5029]

I had a question to ask; what did you use to start the project? There are a whole bunch of .net options that are available but they don't seem to fit my needs for making a game like this. Help please!

[@NVitanovic]

In the newer versions of Visual Studio >2013 Visual C++ is not included by default. When installing the Visual Studio make sure you have checked that option. Then go to Other Languages -> Visual C++ -> Empty project.

[@randall.o8995]

can anyone explain to me how the friend function works at line 62 to 64 ? thanks in advance.

[@Nguyenthao-oj9ku]

very late, maybe you do not need this information anymore: friend to access x and y that are private members of a class.and he uses an overridden operator, in this case,

[@codergirl1518]

Excellent tutorial, exactly what I was looking for!!

[@daemon4683]

So I'm a Java guy, and I see this and I'm just like "what the fuck...?"

[@LuRybz]

java tries to simplify things by describing the code (more verbose) c++ tries to simplify things reducing code. That's how I feel about them.

[@daemon4683]

lucas pinto I prefer more the verbose path.

[@ad0ns371]

C++ is far more direct. Just like lucas pointed out . Also Java is more close to natural language than C++ even tough they both are high language and Python is too.

[@billhosh9165]

You are not a "java guy", but a guy who knows shit about programming. Except it and do not hide behind the excuses.

[@BananaNerd-guzaboo]

Accept* And don't call me a grammar nazi because if you're going to give out criticism you've got to be able to take it. :)

[@immanuelsiburian2135]

you are great. THAK YOU. keep going on sir

[@Dexter101x]

Have you got a video which states where you start off from? Like, because I am a beginner with Visual Studio

[@paranomal2962]

Bro your intro song is from "mein Bizeps brennt" hahaha

[@hienvu5908]

mong a ra video nữa đi ạ huhu

[@narahs22]

Did you get your directions wrong? For example I thought DownRight should be x++,y--. and when you run the code at the end it says the dir'n is DownRight but it goes UpRight from (0,0) to (1,1)

[@willway1234]

When you go down, the y co-ord increases.

[@shahmirkhan9481]

but why does the y co-ord increase when we go down? it must decrease right!!!

[@modoamodoq168]

Because the way your screen is drawn, you screen draws from the top left pixel down to the bottom right, instead of saying that all the Y coordinates are negative, they just have them going positive instead. That is why the y co-ord is increasing as it goes down instead of decreasing.

[@kavindukokila1543]

I have an error:no matching function for call to'cBall::randomDirection()' what is it? Plz help

[@Darksassy]

Can someone help me understand what this function does...and what inline int gety() { return y; } , is used for please. Thanks friend ostream & operator

[@ParsaTaba]

I dunno bro

[@alaaalmhsery718]

why my rand() need to include #include and your not?

[@alaaalmhsery718]

¨how do you get the boxed in - at lign for im still new to coding

[@dhjslabxdhdj3152]

I program with ubuntu and I do not have the library conio.h, how can I install it (I do not have an ide)

[@Nguyenthao-oj9ku]

rand() does not give us a random, I tried to repeat the program many times, and the direction still is 6

[@edriantiburana]

I get this errors : Error 1 error C2614: 'cPaddle' : illegal member initialization: 'cPaddle' is not a base or member 3 IntelliSense: "cPaddle" is not a nonstatic data member or base class of class "cPaddle" please help. I'm new in programming.

hi - tnx for tutorial - i want to write a breakout game in c++ but i don't know how i can ,actually i don't know how to start, so i watched this tutorial. i want to know how i can use this tutorial and change it to a brakout game?

[@omgitzzaaronn5788]

i get this error: 'return': cannot convert from 'int' to 'std::ostream &'

[@piyush9705]

if its a function check if uve used '()'after it.. that's when I usually get that error

[@classim3715]

You should return o letter I not zero bro if you had int function you return a like like 0 like int main(); but with ostream I you should return the letter o;

[@alexwashbach3315]

i copied it exactly and got about 40 errors.

[@jaideepsinghjeji8444]

How?

[@akazecik]

Aren't functions defined inside a class inline by default?

[@johnniegilkerson4724]

Your code does not work fatal error C1010: unexpected end of file while looking for precompiled header.

I have a problem. my application tells me that "rand" was not declared in this scope plese help me

[@faceloltv2594]

#include use this then it is working

[@electromobilegadget5300]

What is the game of the software that you are using to create this game?

[@electromobilegadget5300]

Thank you :)

[@HeldrikBoldhart]

You can do this exact code in Notepad++ using C++ as the language, correct?

[@Lou_0b1]

Correct.

[@tomiikunxd]

you can, but you'd need to compile with which Notepadd++ does not include

[@LostDarkKingEU]

Hey man i keep getting all kinds of errors when trying to run the code. even if i copy the full code listed in the discription. had the same problem with the snake game. tryed typing it over step by step but does't work. please HELP!

[@alaaalmhsery718]

niels-yvo grummel i think that you have to sour what your typing cos its work

[@LostDarkKingEU]

[@obx4454]

how new are you to programming? some of these errors are baby mistage errors. for the undeclared identifier you misplaced some brackets or used x and y before declaring them take a look at your code logically

[@tyru2]

what project type is that

[@seanmccain1450]

Im having a problem apparently rand is not declared in the scope

[@showallmemes6268]

I get an error when I do direction = (eDir)((rand() % 6) + 1); it says that "rand" was not declared in this scope

[@Mister_Gerbelle]

did u forget #include "inustd.h"

[@johnshalenko2551]

Could you explain which kind of application this is?

[@NVitanovic]

It's a C++ application. If you are interested in which template in visual studio did I use, it's an Empty project, with added source file named main.cpp. Check out my first C++ Hello World tutorial for more info.

[@johnshalenko2551]

NVitanovic No need, I figured it out through just watching, decent tutorial by the way.

[@daveygrean3798]

help it wont run, says cant locate iostream? do i need to download it from somewhere?

[@daveygrean3798]

im using turbo c++

[@daveygrean3798]

i just pasted the source code into turbo?

[@yaboitroy8970]

turbo c++ works horribly for most code, visual studio is much better

[@edurd121]

Excuse me but my code like only stays for like 1.500 milliseconds and then it closes

[@vicc.8135]

+Eduardo Bourget might want to try adding system(''pause''); return 0; at the end of your code if your using visual studio as an idea

will this work if i do this on notepad ?

It will work, if you compile it later properly.

[@manriqueiriarte8268]

can someone explain to me why down left he uses y++ and up left he uses y--?

[@elliot8275]

y-- refers to the fact of the position of the object other wise it will be high or to low, (remember in scratch when you tried to code and when you tapped forward and left or right it will only go one or the other) this prevents this

[@classim3715]

Someone just explain that the initial position (0;0) is not center that why if it was center then your logic is right but image the initial position on the top or or bottom it will different direction
