Cocos2d如何切换场景 [英] Cocos2d How to Switch Scenes

问题描述

如何切换cocos2d中的场景？我有我的主类，HellowWorldLayer.h / .m，但我似乎不能正确切换场景。我试过：

How do i switch scenes in cocos2d? I have my main class, "HellowWorldLayer.h/.m" , but i can't seem to switch scenes correctly. I have tried :

[[CCDirector sharedDirector] replaceScene:[Race node]];
//And
[[CCDirector sharedDirector] replaceScene:[Race Scene]];

我放一个断点，我可以看到它是去新的场景，但Button i添加到新场景不显示。我正确创建按钮。然后我把它添加到新的场景中的屏幕像这样：

I put a break point in and i can see it is going to the new scene but the Button i added to the new scene isn't showing up. I am creating the button correctly. Then i am adding it to the screen in the new scene like this:

 [self addChild:Menu];

我刚刚从HolloWorldLayer.m / .h中取得了所有代码，并将其复制到新场景（类），但我无法正确转换。我是新到xcode和cocos2d所以很抱歉，如果这是真的很简单。

I just took all of the code from HolloWorldLayer.m/.h and copied it into the new scene (class) but i am unable to transition correctly. I am new to xcode and cocos2d so sorry if this is really simple.

Race.m

#import "Race.h"
#import "Intermediary.h"

@implementation Race


+(CCScene *) scene{
    // 'scene' is an autorelease object.
    CCScene *scene = [CCScene node];

    // 'layer' is an autorelease object.
    Race *layer = [Race node];

    // add layer as a child to scene
    [scene addChild: layer];

    // return the scene
    return scene;
}

-(id) init{

    if( (self=[super init]) ) {

        NSLog(@"Racing!");
        CCLabelTTF *startLbl = [CCLabelTTF labelWithString:@"Start" fontName:@"Marker Felt" fontSize:20];
        CCMenuItemLabel *startMenu = [CCMenuItemLabel itemWithLabel:startLbl block:^(id sender) {
            NSLog(@"I have been pushed!");
        }];
        startMenu.position = ccp(50,50);
        CCMenu *Menu = [CCMenu menuWithItems:startMenu, nil];
        [self addChild:Menu];


    }
    return self;
}


@end

推荐答案

你的代码，因为它是为我工作。

Your code as it is worked for me.

以下是范例：下载

使用转换效果更好。

[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:1.0 scene:[Race scene] ]];
