This line of code

Code: Select all

_levels = [@[level1, level2] retain];

from the init method keeps giving an error, unexpected '@' in program, is it a typo? I am on xcode 4.2

That line uses the new syntax to define an array, so you would need to be on XCode 4.5 to take advantage of it.

As a workaround, you could use

Code: Select all

_levels = [ [NSArray arraywithObjects:level1, level2, nil] retain];


but I would go ahead and upgrade to 4.5.

Have fun!

Hey thanks rcasey

I was thinking that it was some new 4.5 feature but wasn't 100% sure as I hadn't seen it before. Upgrading is on my todo list.

Thanks again.

Use initWithObjects for 4.2 instead of arrayWithObjects if you are still using 4.2 like me rcasey was 99% Thanks again

Code: Select all

_levels = [[[NSArray alloc] initWithObjects:level1, level2, nil] retain];//4.2

Bloody amazing tutorial!

I'm so happy with the timing as well, I was about to do the old tutorial just as it was updated. Yay for me, haha.

Thank you so much, I love this website.

I´m still in Xcode 4.3.2 and I have an issue with this line in LevelManager.m

return _levels [_curLevelIdx];

What´s wrong with that?

Thanks!

I solved this replacing this line of code

return _levels[_curLevelIdx];

for

return [_levels objectAtIndex: _curLevelIdx];

That uses the new array syntax.

Code: Select all

return [_levels objectAtIndex:_curLevelIdx];

Or you can upgrade to Xcode 4.5

Hi,

Thanks for this amazing tutorial, so good job !

Somewhere at the beginning, you talked about component based architecture for games development.
Is there any of your cocos2d tutorials based on this kind of architecture at this moment ? I would love to know how it works.

Thanks again !
