cocos2d‘s replaceScene

1. new 一个 cocos2d项目

2. 添加一个场景类

// .h文件
#import "CCScene.h"

@interface CCScene_another : CCScene

@end

// .m文件

#import "CCScene_another.h"

@implementation CCScene_another

- (id)init{
    if (self = [super init]) {
        NSLog(@"CCScene_another__init__");
    }
    return self;
}

- (void)onEnter{
    [super onEnter];
    NSLog(@"CCScene_another__onEnter__");
}

- (void)onEnterTransitionDidFinish{
    [super onEnterTransitionDidFinish];
    NSLog(@"CCScene_another__onEnterTransitionDidFinish__");
}

- (void)onExit{
    [super onExit];
    NSLog(@"CCScene_another__onExit__");
}

@end

3. 在HelloWorldLayer.m的init中添加一个replaceScene，当然要包含头文件"CCScene_another.h"

　#import "CCScene_another.h"

- (void)change_scene{
    [[CCDirector sharedDirector] replaceScene:[CCScene_another node]];
}

// on "init" you need to initialize your instance
-(id) init
{
    // always call "super" init
    // Apple recommends to re-assign "self" with the "super" return value
    if( (self=[super init])) {
        NSLog(@"hello__init__");
        // create and initialize a Label
        CCLabelTTF *label = [CCLabelTTF labelWithString:@"Hello World" fontName:@"Marker Felt" fontSize:64];

        // ask director the the window size
        CGSize size = [[CCDirector sharedDirector] winSize];
    
        // position the label on the center of the screen
        label.position =  ccp( size.width /2 , size.height/2 );
        
        // add the label as a child to this Layer
        [self addChild: label];
        
        // replaceScene
        [self performSelector:@selector(change_scene) withObject:nil afterDelay:0.1f];
    }
    return self;
}
