iphone - 在单个 iPhone View 中使用 Cocos2d

Question

我有一个主要使用标准控件的 iPhone 应用程序。有一种 View 是用 OpenGL 渲染的(花哨的图形)。为了节省自己的大量工作，我环顾四周，发现了 Cocos2d。看起来它正是我所需要的(OpenGL ES，使用起来相对简单)，但我遇到了问题。

我不知道如何限制Cocos2d仅存在于单个 View 中。之前，我在 View 中实现了 OpenGL 内容，并使用简单的 ViewController 在导航 Controller 中呈现它。在这里，Cocos2d 似乎需要做更多的事情，而且我不确定如何将其填充到我使用原始 OpenGL 所做的相同 ViewController/View 方法中。

更新:这就是我正在做的事情。翻到下一个粗体，看看我现在在做什么。

#import <UIKit/UIKit.h>


@interface CocosController : UIViewController {
    UIWindow *window;
}

@property (nonatomic,retain) UIWindow *window;

@end

还有我的 CocosController.m:

#import "CocosController.h"
#import "SomeScene.h"
#import "cocos2d.h"

@implementation CocosController

@synthesize window;

// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
    // Initialization code
    CC_DIRECTOR_INIT();
    CCDirector *director = [CCDirector sharedDirector];

    //landscape
    [director setDeviceOrientation:kCCDeviceOrientationLandscapeLeft];
    [director setDisplayFPS:true];

    //turn on multi-touch
    EAGLView *cocosView = [director openGLView];
    [cocosView setMultipleTouchEnabled:true];

    self.view = cocosView;

    //default texture formats...
    [CCTexture2D  setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888];

    [[CCDirector sharedDirector] runWithScene:[SomeScene scene]];
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [[CCDirector sharedDirector] purgeCachedData];
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
    [[CCDirector sharedDirector] release];
    [window release];
    [super dealloc];
}


@end

最后，我如何尝试呈现它(通过单击按钮):

CocosController *cocosController = [[CocosController alloc] init];
[[self navigationController] pushViewController:cocosController animated:true];

这是新方法，但结果相同。

我的AppDelegate的ApplicationDidFinish部分:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

    // Override point for customization after application launch.
    if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
        [CCDirector setDirectorType:kCCDirectorTypeThreadMainLoop];

    CCDirector *director = [CCDirector sharedDirector];
    [director setDisplayFPS:YES];

    state = kStateEnd;

    // Add the navigation controller's view to the window and display.
    [window addSubview:navigationController.view];
    [window makeKeyAndVisible];

    return YES;
}

我用来呈现 View 的 CocosController:

#import "CocosController.h"
#import "cocos2d.h"
#import "SomeScene.h"

@implementation CocosController

@synthesize mainView;

// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
    EAGLView *glview = [EAGLView viewWithFrame:CGRectMake(0, 0, 250,350)];
    [mainView addSubview:glview];

    CCDirector *director = [CCDirector sharedDirector];
    [director setOpenGLView:glview];

    CCScene *scene = [CCScene node];
    id node = [SomeScene node];
    [scene addChild: node];

    [director runWithScene:scene];
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
    [super dealloc];
}

@end

这一点来 self 拥有的详细 View Controller 中的按钮单击，它应该使整个事情出现:

CocosController *cc = [[CocosController alloc]init];
cc.mainView = self.view;
[[self navigationController] pushViewController:cc animated:false];

Answer 1

你所做的事情似乎有些过分了。 CC_DIRECTOR_INIT(); 用于初始化 View 和 CCDirector，建议您将 cocos2d 附加到主视图。

如果您查看 Cocos2d 中提供的名为 AttachTest 的示例(请参阅文件 attachDemo.m)，您可以了解如何附加 CCDirector 到任何 View 。以下是示例使用的代码:

EAGLView *glview = [EAGLView viewWithFrame:CGRectMake(0, 0, 250,350)];
[mainView addSubview:glview];

CCDirector *director = [CCDirector sharedDirector];
[director setOpenGLView:glview];

在此代码段中，创建了一个新的 EAGLView，然后将其设置为 CCDirector 的 openGLView。

我的建议是像往常一样创建 View Controller 和空 View (可能使用 Interface Builder，或上面的代码)，然后在 loadView 方法中附加 CCDirector 到该 View 。
