In your header file declare them as
extern const int kTileSize;
extern const int kGridSizeX;
extern const int kGridSizeY;
extern const int kNumberOfTiles;
an then in your implementation file as
const int kTileSize = 32;//32
const int kGridSizeX = 19;//19
const int kGridSizeY = 16;//16
const int kNumberOfTiles = 4;//4

hello
I'm trying to create a constant that can be used in 2 different
classes but the compiler keeps giving me the following error
GokubanView.h:40: error: variable-size type declared outside of any
function
where the line is:
int levelGrid[kGridSizeX][kGridSizeY];
I'm trying to define the constant in a file called globalConstants.h
like so:
#ifndef _globals_
#define _globals_
const int kTileSize = 32;//32
const int kGridSizeX = 19;//19
const int kGridSizeY = 16;//16
const int kNumberOfTiles = 4;//4
#endif
i've tried using
extern const int kGridSize = 19
but the compiler also complains saying something to the effect:
constant declared extern with initial value
basically what i want to be able to do is
in one class do the following:
@interface levelClass : Object
{
int levelData[kGridSizeX][kGridSizeY];
}
@end
and in another file:
GokubanView..m:
- (void)initializeLevel {
int i,j;
for(i = 0; i < kGridSizeX; i++) {
blah blah blah
levelData[i][j] = some value
}
any help would be greatly appreciated,
Eric
