Here's an interesting dilemma. I have two CCMenus being loaded on a page, each with two CCMenuItemImages as buttons. All four buttons call the same function, which decides what to do using a switch statement that goes off the caller's tag value.
The four buttons are start, tutorial, options, and credits. I have them split into two menus so that I can horizontally and vertically align them in a faux grid. This layer is the main menu layer, so it is the first thing to load after the game starts.
The problem is that when the game first loads, pressing _any_ button will call the "options" button. Not just the function, pressing any button on the menu **activates the options button's selected state**. If I press "start," for instance, the start button's selected state (a glow around the image) doesn't workâthe options button glows instead.
Once I get into the options menu, and then back out of it, the main menu works as expected, with each button activating its requisite function.
Here's my .h:
#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "Constants.h"
#import "GameManager.h"
@interface MainMenuLayer : CCLayer {
CCMenu *mainMenuTop;
CCMenu *mainMenuBottom;
}
@endAnd this is my .m:
#import "MainMenuLayer.h"
// Private methods
@interface MainMenuLayer()
- (void)displayMainMenu;
@end
@implementation MainMenuLayer
- (void)playScene:(CCMenuItemFont*) itemPassedIn {
if ([itemPassedIn tag] == 1) {
CCLOG(@"Tag 1 found, Scene 1");
[[GameManager sharedGameManager] runSceneWithID:kGameplayScene];
} else if ([itemPassedIn tag] == 2) {
CCLOG(@"Tag was: %d", [itemPassedIn tag]);
CCLOG(@"Placeholder for next chapters");
} else if ([itemPassedIn tag] == 3) {
CCLOG(@"Tag 3, Options");
[[GameManager sharedGameManager] runSceneWithID:kOptionsScene];
} else if ([itemPassedIn tag] == 4) {
CCLOG(@"Tag 4, Credits");
[[GameManager sharedGameManager] runSceneWithID:kCreditsScene];
}
}
