Pass level time to Congratulations scene cocos2d - iphone

Question

Just wondered if someone could quickly give me a hand. Im building a simple puzzle slider game, ive added a timer to the game now and all i want to do is pass the time it took to complete the puzzle over to the congrats scene. Could anyone just have a look at my code see where im going wrong please?
play.h
#import "cocos2d.h"
#import "Box.h"
#interface PlayLayer : CCLayer
{
int timeInt;
int secs;
int mins;
CCLabel *timeLabel;
NSString *TotalTimeString;
}
#property (nonatomic, assign) int timeInt;
#property (nonatomic, assign) int secs;
#property (nonatomic, assign) int mins;
#property (nonatomic, retain) NSString *TotalTimeString;
#end
Play.m
#import "PlayLayer.h"
#import "Congrats.h"
#implementation PlayLayer
#synthesize timeInt;
#synthesize secs;
#synthesize mins;
#synthesize TotalTimeString;
-(id) init{
self = [super init];
TotalTimeString = [NSString stringWithFormat:#"Time: %02d:%02d", mins, secs];
timeLabel = [[CCLabel labelWithString:TotalTimeString dimensions: CGSizeMake(130,27) alignment: UITextAlignmentCenter fontName:#"Marker Felt" fontSize:25.0] retain];
timeLabel.position = ccp(155,430);
[self addChild:timeLabel];
[self schedule: #selector(tick2:) interval:1.0];
return self;
}
-(void) tick2: (id) sender{
timeInt++;
secs = timeInt % 60;
mins = timeInt / 60;
[timeLabel setString: TotalTimeString];
}
-(void) check: (id) sender data: (id) data{
int valueToCheck = 0;
bool breakOut = false;
for (int y=0; y < box.size.height && !breakOut; y++) {
for (int x=0; x < box.size.width && !breakOut; x++) {
Tile *tile = [box objectAtX:x Y:y];
if (tile.check != [box hashOfXY:x y:y]) breakOut = true;
valueToCheck++;
}
}
int totalTiles = box.size.width * box.size.height;
if (valueToCheck == totalTiles){
[[CCDirector sharedDirector] replaceScene:[CCFadeTransition transitionWithDuration:1 scene:[Congrats node]]];
CCScene *scene = [Congrats scene];
scene.TotalTimeTakenWhenDiedString = TotalTimeString;
[[CCDirector sharedDirector] replaceScene:scene];
}
}
#end
Congrats.h
#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "PlayLayer.h"
#interface Congrats : CCLayer {
CCLabel *timeLabel;
NSString *TotalTimeTakenWhenDiedString;
}
#property (nonatomic, assign) NSString *TotalTimeTakenWhenDiedString;
+(id) scene;
#end
Congrats.m
#import "Congrats.h"
#import "DifficultyLevel.h"
#import "PlayLayer.h"
#import "PlayLayerMedium.h"
#import "PlayLayerHard.h"
#import "MainMenu.h"
#implementation Congrats
#synthesize TotalTimeTakenWhenDiedString;
+(id) scene {
// ‘scene’ is an autorelease object.
CCScene *scene = [CCScene node];
// ‘layer’ is an autorelease object.
Congrats *layer = [Congrats node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
// on “init” you need to initialize your instance
-(id) init {
// always call “super” init
// Apple recommends to re-assign “self” with the “super” return value
if( (self=[super init] )) {
timeLabel = [[CCLabel labelWithString: TotalTimeTakenWhenDiedString dimensions: CGSizeMake(130,27) alignment: UITextAlignmentCenter fontName:#"Marker Felt" fontSize:25.0] retain];
timeLabel.position = ccp(155,430);
}
return self;
}
-(void) goToGameplay: (id) sender {
[[CCDirector sharedDirector] replaceScene:[CCFadeTransition transitionWithDuration:1 scene:[MainMenu node]]];
}
}
#end
I was kind of hoping that, that would work. But i keep getting this error "error: request for member 'TotalTimeTakenWhenDiedString' in something not a structure or union"
Anyone help at all?
Cheers

Answer 1

Your problem is here:
CCScene *scene = [Congrats scene];
scene.TotalTimeTakenWhenDiedString = TotalTimeString;
The object scene is of type CCScene and you are trying to access TotalTimeTakenWhenDiedString on it. But that is a property of Congrats, not of CCScene.
Here's a suggestion which might work, by getting the Congrats object out from scene. (Caveat: I'm not familiar with cocos2d, and I only looked it up quickly here. This may be a terrible way to be doing it!)
Change here:
// add layer as a child to scene
[scene addChild:layer z:0 tag:1]; // tag it with 1
and here:
CCScene *scene = [Congrats scene];
Congrats *congrats = (Congrats *)[scene getChildByTag:1]; // get the congrats child object, which we tagged 1
congrats.TotalTimeTakenWhenDiedString = TotalTimeString;
[[CCDirector sharedDirector] replaceScene:scene];

Answer 2

... Why dont you just create a singleton class which you can use as a global object? and access/update it anywhere in the game?
