Question

I know this is a very beginner question, but I’ve been struggling to figure it out.

I’m trying to build an iOS game (using cocos2d) and so I have 2 sets of files

GameScene.h and gameScene.m
MainMenu1.h and MainMenu1.m

GameScene has the sharedcode I’ve leaned to put in.

I call my MainMenu1 – the user chooses how many players from a MenuItemwithImage and that calls ChoosePlayers

I can figure out which menu item was touched, but I need to pass the number of players back to GameScene

in GameScene I put in

-(void) setPlayers (nsinteger*) players
{
totalplayers = players;
}

so in mainmenu1 chooseplayers i did

[[GameScene SharedGameData] setPlayers : 2];

but that doesn’t work.

I’m sorry, I don’t have the code in front of me (not until tonight); i’ve been searching for hours and can’t figure it out.

Answer 1

Your method format is incorrect. It should be:

-(void)setPlayers:(NSInteger)players;

NSInteger is not a pointer either.

To pass multiplie values, you coud either pass in an array, or:

-(void)setPlayers:(NSInteger)firstValue withSecondValue:(NSInteger)secondValue; and when you want to call it, it would look like this:

[[GameScene SharedGameData] setPlayers:2 withSecondValue:4];
