Question

sprite.extraData

Is a NSMutaleDictionary.

In one method, I do this:

[sprite.extraData setObject:@"HELLO" forKey:@"NAME"];

Now, in a different method, I do this:

    for (CCSprite *anim in animations) {
        NSLog(@"%@",[anim.extraData objectForKey:@"NAME"]);
    }

Where sprite is a child of the NSMutableArray animations.

When I try to print the name, I get (null). Why is that?

Answer 1

Did you initialize the extraData of sprite?

Make sure you do something in the CCSprite init file like:

extradata = [[NSMutableDictionary alloc] init];
