Problems with the switch statement
Post: #16
Well, that got me down to only five errors, which shouldn'tt be too hard to fix. Thanks for all the help!

Alright, now I'm getting a 3 parse errors in Game.h. See code.
Code:
/* Game */
#import <Cocoa/Cocoa.h>
#import "Cell.h"
#define BOARD_SIZE 8
enum { STATE_TITLE, STATE_PLAYING, STATE_GAME_OVER };
@class GameController, GameView;
Cell* board[BOARD_SIZE] [BOARD_SIZE]; // game board
@interface Game : NSObject
- (void)setState:(int)newState;
- (int)state;
- (Cell*)cellAtRow(int)row andColumn:(int)column;
- (void)resetBoard;
{
IBOutlet GameController *gamecontroller;
IBOutlet GameView *gameview;
int state; // current Game state
}
@end

First, what are the errors?
Second, don't you need to include the headers that define GameController, GameView, etc?
(and everyone mistypes
)

It's not magic, it's Ruby.

Don't include headers in headers, as a general rule. Forward declarations are perfectly sufficient in this case.

Firstly, Cell.h doesn't have anything in it so far, so I don't know why I was told to do it,(But I don't know alot of what I'm doing
). Secondly the errors were not actually in Game.h(I should have made this clear). What Happens is, I have two files, GameView.m and GameController.m. They are both getting three error messages;
"parse error before '(' token"
"parse error before '{' token"
"parse error before '}' token". The little Red circle with the "x" appears in each of them next to the line; "#import "Game.h". Since neither GameView.m or GameController.m have (, {, or }, I assumed the problem was in Game.h. So I really have no idea what's going on.
Perhaps I should use a different tutorial?

- (Cell*)cellAtRo[b]w([/b]int)row andColumn:(int)column;Needs a colon after cellAtRow. Should help a bit.
Post: #22Code:
#import "Cell.h"What Keith said.
Code:
#define BOARD_SIZE 8
enum { STATE_TITLE, STATE_PLAYING, STATE_GAME_OVER };Fine...
Code:
@class GameController, GameView;Ok...
Code:
Cell* board[BOARD_SIZE] [BOARD_SIZE]; // game boardRed alert.
You're declaring a global variable "board" here. Bad bad bad.
Code:
@interface Game : NSObject
- (void)setState:(int)newState;
- (int)state;
- (Cell*)cellAtRow(int)row andColumn:(int)column;
- (void)resetBoard;
{
IBOutlet GameController *gamecontroller;
IBOutlet GameView *gameview;
int state; // current Game state
}
@endDEFCON 1. This isn't valid at all.
A) You've completely mixed up where the braces and member variables go. Revisit Objective-C syntax 101.
B) What maximile said.
What you should have is:
Code:
#import <Cocoa/Cocoa.h>
#define BOARD_SIZE 8
enum {
STATE_TITLE,
STATE_PLAYING,
STATE_GAME_OVER
};
@class GameController, GameView, Cell;
@interface Game : NSObject
{
Cell * board[BOARD_SIZE][BOARD_SIZE];
IBOutlet GameController * gamecontroller;
IBOutlet GameView * gameview;
int state;
}
- (void)setState:(int)state;
- (int)state;
- (Cell *)cellAtRow:(int)row andColumn:(int)column;
- (void)resetBoard;What tutorial are you reading? Either you're messing up the reading part pretty thoroughly or it has some pretty shoddy code examples...

How about ... adding some brackets.
switch([game state])
{
case STATE_TITLE: {
[self displayTitle:rect];
break;
}
case STATE_PLAYING: {
[self displayPlaying:rect];
break;
}
case STATE_GAME_OVER: {
[self displayGameOver:rect];
break;
}
default:
break;
}
switch([game state])
{
case STATE_TITLE: {
[self displayTitle:rect];
break;
}
case STATE_PLAYING: {
[self displayPlaying:rect];
break;
}
case STATE_GAME_OVER: {
[self displayGameOver:rect];
break;
}
default:
break;
}

We already solved the Switch function problem, it was actually a problem earlier in the code. But thanks anyway…

Well, It's pretty good practice, and as a bonus, you get scoped code
It's not magic, it's Ruby.
