and

[TheKahl10]

[scott71785]

LMAO 4:24 FARTTTT

[lordAnarax]

Shit tutorial. When I tried connecting the enemy with the red ball, and the player with the grey ball, nothing happened. Such a great tutorial man, I congratulate you.

[IYIrIYIax]

"Receiver Type 'View Controller' for instance message does not declare a method with selector 'checkCollision'.....

Keep getting this error?

Any Help? Thanks.

[scotssux2]

@IYIrIYIax

You need to call it in your view controller

@interface ViewController : UIViewController { IBOutlet UIButton *startbutton; NSTimer * randomMain; CGPoint pos; IBOutlet UIImageView *player; IBOutlet UIImageView *enemy;

} -(IBAction) start;

-(void) checkCollision;

[0scraps0]

@IYIrIYIax just move the 'checkCollision' method above the 'onTimer' method, then it should work.

[woodliceolympics]

i am getting message does not declare a method with selector 'checkCollision' and alert release isn't allowed for some reason. can u help plz?

[scotssux2]

@woodliceolympics woody! i am getting the same errors! leme know if you've found out how to fix it, Thanks!

For Flying Spaghetti Monster's sake, blow your nose!

[kikbut101]

next time don't make a video when your sick but i liked the tut

[cascarrabias30]

This would be a class A tutorial if you could edit out the bugger-swallowing and the farts. I was learning and gagging, taking a break, then learning and gagging again. It was rough. I have a 32 band graphic eq you can borrow, old school, if you want.

[TheLuckyFactor]

i swear i hurd a fart..

[markmsify]

@TheLuckyFactor me too ~ 4.23

[Chiisuchianu]

I have a question, is it possible to duplicate UIImage for like a hundred times?? if yes, how?? sorry being such a noob...

[pecololek]

[sidorueckwaerts]

@pecololek objective-c

[0TheDreamState0]

This didn't help me at all... Not saying that you're bad, because you are obviously a really good programmer, but get some brains and think about who's going to be viewing this. -.- Great video though for someone who understands it!

[fwragervold]

Im thinking about buying iOS SDK and getting started myself, what kind of 'code' are you using when making iPhone Apps? PHP,CSS, or..? Also how big of a difference is it to develop apps using Windows instead of Mac OS?

[RjProgrammes]

@bfolkrod uiimageview as a background and there you have it!

[RjProgrammes]

hi, i have followed your instructions but i have a label which counts up which is the score. how would i stop it when it collides and reset it so it is ready?

thanks rafee

[TheDom4224]

what's the programming language?

[RjProgrammes]

@TheDom4224 cocoa touch or somet?

[XfStef]

there is absolutely no one on the whole internet who can explain object oriented programming in a way that beginners can pick it up...

[bestgamer6661]

@cuberegister,it gives me like 100 errors

[RjProgrammes]

@bestgamer6661 you have obviously done it wrong then!

[TheAppWizard9000]

Could you make a tutorial that shows "you've been hit you time is...) and after says want to upload this picture to Facebook

[syckdev]

Great video! Very informative and easy to follow! I did this with xcode 4.2 and iOS 5 for iphone. Works great except the ball positions do not reset once you lose and dismiss. Is there a way to do this?

[leelawton5]

Is there an actual app like this? it seems fun haha

[Dzund94]

just made that there in under 30 minutes, great tutorial!! tried to intergrate the timer into it and got 8 errors :/

please make more! :D

[infopb44]

can you do an xcode 4 vid on multi tab bars with multi navigation table views? Thanks

[sickojim]

Hi, I have checked the code several times, and I get ......may not respond to '-checkCollision' along side the [self checkCollision]; statement.

Any Ideas? I am using iOS 10.6.6

Cheers Jim

[akiitrivedi]

@sickojim i get the same error..

[aricbutler]

Nice Video!

[ShockWater3]

hey could you send me the code i got 4 warnings and 7 errors

[jasonapawlak]

Thanks, very helpful in getting started.

[billionaire123456]

can u send me the code pls :D :D

[amirams]

Nice tutorial... except that if a person has come so far, I really don't think you should spend time on things such as "don't put a semicolon in the middle of your IF clause".

[superchadfilms]

How did you learn how to program? I pretty much don't know anything and would like to.

[98cwc]

I keep getting a "SIGABRT" error on the "-(void)onTimer" Method. It shows it on the " [self checkCollision];" I need help. If anyone knows how to fix this please let me know!! Thanks

[bharathptl]

@98cwc ... i am getting same error. did u found any solution. if so please tell me.

[AxapliTV]

@98cwc check your spaces between the codes

[Kramblueify]

Thanks for the Tut it helped me. My eyes are watering now after listening to you and your cold :)

[hhuss9]

make a video when youre not sick, you fucking idiot.

[zeroisamazing]

I tried to build this but i got tons of errors. Can you send me the code?

thanks

[zeroisamazing]

I tried to build this but i got tons of errors. Can you send me the code?

thanks

[ipodtouchacker]

i build and go and it just keeps saying "dismiss" then goes away for like .25 seconds then reappears and it never works. this happens when i click begin. i have connected everything in IB too

[MrMaggle]

Thanks, really helpful vid.

[claudia33433]

Helpful video, thanks. But there's really no need to read whole sections of code to us. It is clear enough if you put it in full-screen mode, and also people can pause it if they need to type things in. Just explain the concepts! :)

[Chalingo13]

Hey dude can I get the source code

[Sackbot342]

Can you please send me the source code. Thanks for the tutorial its awesome, i even bought roller baller 2!!!!

[thebluedoor01]

hey your screen is gigantic!!!! what is it? 32 inches??

[johnydee187]

hey dude how do you add another ball?

[eddieemit7]

do you have any recommendations for books on game programming for the iphone? I am reading one, but it is a little tough because it seems to lack in explaining what is going on in the process. It seems like when i follow along with tutorials on here, i get different results then they get. Not sure if it is version differences in xcode or not.

love the video, keep them coming, i seem to learn more from youtube videos then books.

[Delizsieg]

you have itunes appstore link ? i will purchase some! your vid helps me a lot.

@Techn0Junki3 

[scarthinator]

how would you go about having the enemy ball gradually get faster?

[Sanguer]

@scarthinator Put the speed as variables and in the timer function put an integer variable that adds 1 always the function is called, then you ( in the end of the timer ) you check if the integer variable is five, if it is, you adds 1 to the speed of the ball ( x and y ) and sets the integer variable to 0 again, if it is not, you do nothing.

[musicnrd]

Very nice. I'm still a "beginner" as far as coding goes. Your Xcode videos are quite informative.
