Question

Annoying newbie problem here. This variable isPlayerTouchingAnotherPlayer is being set to true as soon as I touch the piece. I’m almost positive I know why but I can’t find a way to display this in log to confirm. I could probably do it by setting different flag numbers for each of the objects but I was hoping there is another way.

The problem is that piece is an object that is also located in p1Array so as soon as I touch it it hits itself and isPlayerTouchingAnotherPlayer is evaluated to true.

Is there a way I could print out the view or image name of the objects touching somehow to confirm this? And furthermore, is there a way to somehow avoid this annoying conflict.

for (int i = 0; i <[p1Array count]; i++) {
    UIImageView *tempP1;
    tempP1 =[p1Array objectAtIndex:i];

    if (CGRectIntersectsRect(piece.frame, tempP1.frame)) {
        NSLog(@"selected piece: %@, touched piece: %@ ", piece, tempP1);
        isPlayerTouchingAnotherPlayer = TRUE;
    }
}

Answer 1

why not use fast enumeration and skip the image view you are not interested in checking.

for (UIImageView *imageView in p1Array) {
    if (imageView == piece)
        continue;

    if (CGRectIntersectsRect(imageView.frame, piece.frame)) {
       // do whatever
    }
}

it seems like you are already printing out the names of the objects touching in the code sample you have provided. if you want to print out specific properties of the objects you can do that to.
