Question

Hi dear developers! I’m just wrote my first iphone game. But i have faced an information output problem below

myStr = [NSString  stringWithFormat:@"Best Score:", counter];

The variable “counter” each time changes value at hit in the enemy. But in the information output I receiving always a zero, like “Best Score: 0”. Help to understand and fix that problem.

Class Texture & Sprite I’ve got from John Ward from http://www.karmatoad.co.uk

Some code here:

myStr = [NSString  stringWithFormat:@"Best Score:", counter];
_Texture = [[Texture alloc] initWithText: myStr fontSize:24];
_Sprite = [[Sprite alloc] initWithTexture: _Texture];
[_Sprite drawSprite];

As others have suggested, you are missing the placeholder for your variable. I just wanted to provide some background:

NSString supports the format characters defined for the ANSI C function printf(), plus %@ for any object.

In format strings, a % character announces a placeholder for a value, with the characters that follow determining the kind of value expected and how to format it, i.e. format specifiers.
