Question

so I have a label and I would like that when an image collide with another image it increase of 10 . score = score +10; but instead of this it increase of 40 I don’t know why . so here is my code :

-(id) init
{
    if( (self=[super init] )) {

        [self schedule:@selector(update:)];

        score = 0;

        scoreLabel = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"%d",score] fontName:@"PUSAB___.TTF" fontSize:15 ];
        scoreLabel.position=ccp(450,30);
        [self addChild:scoreLabel];
    }
}

- (void)update:(ccTime)dt {
    if (CGRectIntersectsRect(mangeurRect, targetRect)) {
        [targetsToDelete addObject:target];     
        score=score + 10; ;// Not really, but your score changes somehow...
        [scoreLabel setString: [NSString stringWithFormat:@"%d",score]];
    }                       
}

sorry for my english I’m french :/

I think that there is no frame you are getting in the CGRectIntersectsRect. You should Try the Below code

- (void)update:(ccTime)dt {

if (CGRectIntersectsRect([mangeurRect frame], [targetRect frame])) {
    [targetsToDelete addObject:target];     
    score += 10;
    [scoreLabel setString: [NSString stringWithFormat:@"%d",score]];
}                       

}

OR

- (void)update:(ccTime)dt {

if (CGRectIntersectsRect([mangeurRect boundingBox], [targetRect boundingBox])) {
    [targetsToDelete addObject:target];     
    score += 10; 
    [scoreLabel setString: [NSString stringWithFormat:@"%d",score]];
}                       

}

By this you would probably get the score increased whenever the images collide with each other.
