Cocos2d ユーザの面倒だったところに手が届く、Kobold2d の親切設計

Kobold2D ちょっと使ってみました。障りだけですが、よく設計されているのがわかります。
良いなと思った事を記述します。

AppDelegate, RootViewControllerがシンプル

cocos2d を使っていると、AppDelegate が非常に複雑になってしまいます。また、標準でかなり長いAppDelegateに、自分のコードを追加するので、バージョンアップのときのマージが大変です。それが、Kobold2dの場合は、cocos2d関係のコードがすべて KKAppDelegate にまとめられていて、各アプリでは、そのアプリに関係する事だけ書けばいいようになっているので、バージョンアップも楽そうです。
こんな感じです。
AppDelegate.h

#import “KKAppDelegate.h”

@interface AppDelegate : KKAppDelegate
{
}
@end

AppDelegate.m

#import “AppDelegate.h”

@implementation AppDelegate

// Note: only override the UI/NSApplicationDelegate methods that you absolutely must handle yourself.
// In most cases you will still want to call the [super ..] implementation,
// unless you want to override the KKAppDelegate behavior entirely.

// Called when Cocos2D is fully setup and you are able to run the first scene
-(void) initializationComplete
{
// If iAd is enabled and you want to supply your own AdBannerViewDelegate, use this code:
//[[KKAdBanner sharedAdBanner].adBannerView setDelegate:yourAdBannerViewDelegate];

// Note: if you specify FirstSceneClassName in startup-config.lua you do not need to call runWithScene at all!
// If you have to, you can still call runWithScene here, for example to add some logic to select one of many scenes to run first
//[[CCDirector sharedDirector] runWithScene:[test test]];
}

@end
[/cc]
RootViewController.m
[cc lang=”ObjC”]

#import “RootViewController.h”

#ifdef KK_PLATFORM_IOS

@implementation RootViewController

// Note: only override the UIViewController methods that you absolutely must handle yourself.
// In most cases you will still want to call the [super ..] implementation,
// unless you want to override the KKRootViewController behavior entirely.

@end

#endif
