Trying to make a room picks random?

Posted 26 July 2011 - 09:06 PM

I am writing this code where a player can enter different rooms, and i can not get it to give me a random room when I enter the bathroom. My code will build but this suggestion comes up and the program shuts down when i enter the bathroom.Here is the message i get / warning: incompatible Objective-C types 'struct NSArray *', expected 'struct Room *' when passing argument 2 of 'setExit::' from distinct Objective-C type/
here is my code
#import "GameWorld.h"

@implementation GameWorld

	static GameWorld *theInstance = nil;
	if (!theInstance) {
		theInstance = [[[self class] alloc] init];
	return theInstance;

	connections = [[NSMutableDictionary alloc] initWithCapacity:10];
	Room *livingroom, *hallway1, *kitchen, *mbedroom, *bedroom2, *bedroom3, *frontdoor, *hallway2, *bathroom, *stairs, *outside;
	self = [super init];
	if (self) {
		// Create the rooms
