回到Xcode中,新建一个EndLayer类,继承于CCNode.因为我们得在其类方法中创建实例变量,所以我们得建立几个实例变量的属性.打开EndLayer.h文件,修改内容如下:

#import "CCNode.h"

@class MainScene;

@interface EndLayer : CCNode

@property (nonatomic,strong) CCLabelBMFont *msgLabel;
@property (nonatomic,strong) CCLabelBMFont *restartLabel;
@property (nonatomic,weak) MainScene *mainScene;

+(instancetype)endLayerWithMainScene:(MainScene*)mainScene message:(NSString*)msg;

@end

接着打开EndLayer.m文件添加如下代码:

#import "EndLayer.h"
#import "MainScene.h"

@implementation EndLayer

-(void)restartTapped:(id)sender{
    CCScene *scene = [CCBReader loadAsScene:@"MainScene"];
    CCTransition *transition = [CCTransition transitionFadeWithColor:[CCColor whiteColor] duration:0.5];

    [[CCDirector sharedDirector]replaceScene:scene withTransition:transition]; } -(void)onEnter{ [super onEnter]; [self.msgLabel runAction:[CCActionScaleTo actionWithDuration:0.5 scale:1.0]];
    [self.restartLabel runAction:[CCActionScaleTo actionWithDuration:0.5 scale:1.0]];
}

+(instancetype)endLayerWithMainScene:(MainScene*)mainScene message:(NSString*)msg{
    EndLayer *endLayer = (EndLayer*)[CCBReader load:@"EndLayer"];
    endLayer.mainScene = mainScene;
    endLayer.msgLabel.string = msg;
    endLayer.msgLabel.scale = 0.1;
    endLayer.restartLabel.scale = 0.1;

    return endLayer;
}

@end

注意我们在其onEnter方法中实现了原代码中的菜单动画效果,现在编译运行app,效果如下:

OK!至此我们全部完成了原代码的转换工作,该系列8篇博文到此告一段落.

本猫猪将在新开辟博文”A*寻路算法的Cocos2D实现”的系列文章中,继续CatMazeV3项目的扩展旅程,敬请期待,再会! ;)
