Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

Retina Display coordinate problem.

I try to display image to the Screen at Retina iPhone.
So I used this code.

#define ScreenWidth 960
#define ScreenHeight 640

void ConvertCoordf(float* x, float* y)
{
int height = ScreenHeight;
if ( height / 2 > *y )
*y += (height / 2 - *y) * 2;
else if ( height / 2 < *y )
*y -= (*y - height / 2) * 2;
}

void DISPLAY_UPDATE(char *name, int x , int y , int startx, int starty , int w , int h ,float rotation)
{
CCSprite *sprite = [[CCSprite spriteWithFile:[NSString stringWithUTF8String:name] rect:CGRectMake(startx, starty, w, h)] retain];
float drawX = x, drawY = y;
CGSize size = [sprite contentSize];

int nWidth = size.width;
int nHeight = size.height;
drawX = drawX + nWidth/2;
drawY = drawY - nHeight/2;

ConvertCoordf(&drawX, &drawY);
drawY -= nHeight;
[sprite setPosition:ccp(drawX, drawY)];
[sprite setAnchorPoint:CGPointMake(0.5, 0.5)];
[sprite setRotation:rotation];
[_mainLayer addChild:sprite];
[sprite release];
}

Unfortunately, the image doesn't display correctly.
The image's position is wrong.
But in other iphone, it display correct.
What's the matter?
What's the problem in this coordinate convert?
