I have a simple spine project in cocos2d and I want to know the current animation that's being played (the string name) but I can't find any function to get that in the CCSkeletonAnimation class,
Do you know if there's a way to get that?
Thanks
EDIT - SOLUTION
Hey I found how to to it
AnimationState *a = [mAnimationNode getAnimationState:0];
NSLog(#"Layer touched: %s",a->animation->name);
Where mAnimationNode is a CCSkeletonAnimation,
that works perfectly!!

If Spine does not support a clear way to do it, you might be better off by storing the animation name in a property of your scene when you start it.
On the other hand, since an animation is usually implemented in cocos2d through an action, you could inspect the CCActionManager's numberOfRunningActionsInTarget: method implementation to check how you can access the list of running actions in a given target node.
This is for cocos2d 1.1:
tHashElement *element = NULL;
HASH_FIND_INT(targets, &target, element);
element->actions is the ccArray containing all the running actions.

So, let's say that I am displaying an integer myInt value in OneViewController. Then, while a different view is showing, AnotherViewController, I need to increment or decrement myInt.
So the scope needs to be global or at least be able to be accessed by other viewControllers and it needs to be mutable.
I know that properties one way to do this but I haven't been able to get them to work. I have been importing the header file of OneViewController into AnotherViewController but that wasn't what I was missing.
I've gone through several introductory books but multi-view controller variable work wasn't explicitly covered in any of them. Clearly I'm a beginner so please excuse any conceptual misunderstandings.
Doesn't have to be view controllers -- any sort of custom classes.
In FirstClass.h:
#property(whatever) int someIntInFirstClass;
-(void) someMethodInFirstClass;
SecondClass.h
#property(whatever) FirstClass* myParent;
FirstClass.m
SecondClass* second = [[SecondClass alloc] init];
second.myParent = self;
[second startSomething];
SecondClass.m:
[self.myParent someMethodInFirstClass];
int x = self.myParent.someIntInFirstClass;
self.myParent.someIntInFirstClass = x + 1;
Have a look at ReactiveCocoa library and check how the signal pattern works. The library has to offer a lot of things including the scenario you have just mentioned.

A bit of a learning curve. But worth!
Creating an CCNode, setting it to my player's position- in debug draw I see the physics object, but the sprite is invisible or nil or something. It doesn't crash the sprite simply doesn't appear. The bomb also travels the proper path and it's selector method is called.
Does NOT Appear:
GameObject *bomb = [_useBombArray nextSprite];
bomb.tag = kShipMissile;
[bomb stopAllActions];
NSLog(#"_bombSpawnPoint: %.0f, %.0f", _bombSpawnPoint.x, _bombSpawnPoint.y);
bomb.position = _bombSpawnPoint;
I have gotten it to appear by doing this:
GameObject *bomb = [_useBombArray nextSprite];
bomb.tag = kShipMissile;
[bomb stopAllActions];
bomb.position = ccp(_winSize.width * 0.5, _winSize.width * 0.5);
The _bombSpawnPoint is set prior to this and I do receive proper results on output.
Originally I thought I had called to create the object at an inopportune time in the update. So I changed the function slightly, to be sure it is called in proper order in the update method.
Not sure what's causing this! Please help!
I've created all my objects like this and they've all worked perfectly thus far!
The result of this was caused by the Texture of the Bomb was not in the proper BatchNode.
The error was not triggering until I removed the excess subclasses and used solely the sprite.
The error received was: 'CCSprite is not using the same texture id'
Once I used the other batch node everything worked perfect. Hope this helps someone!
I have a problem.
I have an NSObjectController called "mapController" and I want to put some defaults when the object is created. I do this inside the windowControllerDidLoadNib method of my document, as suggested by the docs. But…
if (![mapController content]){ // No map defined yet.
[mapController add: self]; // This should create the instance.
NSLog(#"%#",[mapController content]); // Gives NULL.
I tried:
BOOL ok = [mapController fetchWithRequest:nil merge:NO error:nil];
NSLog(#"%#",[mapController content]); // Gives NULL.
The content of mapController is in the Core Data "scratch pad" but I can't access it. I have to set one of its attributes like this:
[[mapController content] setValue:[matrix colorReference] forKey:#"mapData"];
This gives no error, the file is marked as changed, but it I test the value:
NSLog(#"%#",[mapController content]); // Gives NULL.
When the heck it the controller's content really HERE? Something appears on the screen but… what actually? Reading the docs doesn't help me…
OK, I found the answer in the docs:
add: Creates a new object and sets it as the receiver’s content object.
Discussion
Creates a new object of the appropriate entity (specified by
entityName) or class (specified by objectClass)—see newObject—and sets
it as the receiver’s content object using addObject:.
Special Considerations
Beginning with Mac OS X v10.4 the result of this method is deferred
until the next iteration of the runloop so that the error presentation
mechanism can provide feedback as a sheet.
That's why
[[mapController content] setValue:[matrix colorReference] forKey:#"mapData"];
worked fine when called elsewhere in the app. It was a few iterations later…
Well… maybe this post will save you a couple of hours you could use to sleep longer.

I don't think its your mapController, I think it is your NSLog. Try this:
NSLog(#"%#", mapController);
also try getting simple data from the content, like the float value of the CGColorRef so you can use other formatters like %f.
I would have tested this but I cannot seem to create an instance of NSObjectController because it is an undeclared identifier. What framework is it defined in? Did you have to #import anything?
I'm coding in Objective-C for the iPhone and I am trying create an array that plays a series of sounds. For example the first time I press the button I want it play sound "0.wav", but the second time I want it to play "1.wav", then "2.wav", "3.wav", etc. Then when I've played a total of 14 sounds (up to "13.wav") I want the loop to start over playing with 0.wav. I've looked around Google and the Apple development documentation for almost 4 days without much luck. So if someone could help me generate a code for this that would be greatly appreciated and if you wouldn't mind could you attempt to explain the code briefly so that I can learn what each part does.
Thank you, Joey
EDIT
Okay I've gotten the Array part down (thanks to Thomas) however neither of us are sure how to implement the soundID from the array to the action where I play the sound and how to play that sound. I used the format Thomas used for his array below if that helps you with your answer.
Thanks, Joey
First, create the array of your different sounds and a variable to hold the current index:
NSArray *sounds = [[NSArray alloc] initWithObjects:#"0.wav", #"1.wav", nil]; // add all your files here
NSUInteger currentSound = 0;
Then, when you handle your button tapped event, go to the next sound, and play it. If it's at the end of your NSArray, go back to index 0:
currentSound++;
if (currentSound >= [sounds count]) {
currentSound = 0;
}
// play the sound. Just call your own method here
[self playSoundWithFilename:[sounds objectAtIndex:currentSound]];
I need to keep an NSPathControl updated with the currently selected path in an NSBrowser, but I'm having trouble figuring out a way of getting notifications when the path has changed from the NSBrowser. The ideal way to do this would just to be to observe the path key path in the NSBrowser, but that gives a KVO can only observe set<key> methods which return void message and no updates (setPath returns a bool success value).
I also tried observing the selectedCell key path, but I'm not getting notifications when the selection there is changed.
Is there some other really obvious way to do this that I'm missing?
Courtesy of Rob Keniger over at Cocoa Dev:
Have you looked at the SimpleBrowser
example in /Developer/Examples? It
shows how to get the current selection
when it is changed by the user,
basically by just setting up the
action of the NSBrowser.
That is indeed the way to do it. Just implement a method like - (void)browserClicked: in your controller and map it to the NSBrowser's action in interface builder with whatever you want to happen each time the selection changes inside that method, e.g.
- (void)browserClicked:(id)browser {
self.pathToSelectedCell = [browser path]; // NSPathControl is bound to pathToSelectedCell
}
I just checked in IB, and it looks like NSBrowser has a selection index paths binding (an array of NSIndexPath objects) that you could possibly monitor with KVO. It's strange but I don't see any mention of it in the docs, so you might need to do a little research to see if that's something you should or shouldn't use, even if it seems to work. If it does, in your KVO observation method you would find the browser's current path, and convert that to an NSURL the path control can use.
If that doesn't work there's also the delegate methods - (BOOL)browser:(NSBrowser *)sender selectRow:(NSInteger)row inColumn:(NSInteger)column and - (BOOL)browser:(NSBrowser *)sender selectCellWithString:(NSString *)title inColumn:(NSInteger)column.
As of 10.6, one can find out which items are selected, by using the delegate callback as follows:
- (NSIndexSet *)browser:(NSBrowser *)browser selectionIndexesForProposedSelection:(NSIndexSet *)proposedSelectionIndexes inColumn:(NSInteger)column
{
NSLog(#"New first item of the new selection is at index %#", [proposedSelectionIndexes firstIndex]);
// Do something with the selected index or indicies
return proposedSelectionIndexes; // Allow the selection to occur by not changing this
}
