CGRectContinsRect problem

[haza100]

hi,
i have a problem with the function if CGRectContainsRect... i only want the score to +1 when a CGRect contains another, and i want the score to +1 only when the user has let go of the CGRect, at the moment if you drag the CGrect inside the other CGRect the score is constantly increasing, and you also don't have to let go of the CGRect, heres my code. Its very simple but i thought it would do the job, but at the moment it isn't.

- (void)touchesMovedNSSet *)touches withEventUIEvent *)event {
UITouch *myTouch = [[event allTouches] anyObject];
bomb.center = [myTouch locationInView:self];

[self checkCollision];
}

- (void)checkCollision {

if(CGRectContainsRect(redzone.frame, bomb.frame)) {

[self addScore];

}
}

- (void) addScore {
{
score = score +=1;
}

scoreLabel.text = [NSString stringWithFormat:@"%d", score];
}



Thanks, haza.

If you want this to trigger when they drop the CGRect then you probably want to trigger it on "touchesEnded:withEvent:" , not on "touchesMoved:withEvent:"

yeah, but the you cant actually see the CGRect move with your finger so it looks wierd.
is there any way to make it follow your finger and use the touchedEnded function at the same time.
thanks.

Then keep the bomb.center=blah in touchesMoved, but move the [self checkCollision] into touchesEnded.
