几种方法创建cocos2d游戏菜单

从学习cocos2d的官方例子入手.官方的MenuTest例子,提供了4个层来展示各种菜单效果和用户交互的实现.

1.----------------------

#import "AppDelegate.m"

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(UIApplication*)application

{
    // 以上省略了大量初始化代码
    CCScene *scene = [CCScene node];
    // 这里是关键要学习的部分.
    // 既往我理解,放在同一个Scene里的多个Layer,同时按不同的z-order显示
    // 存在先后显示顺序的Layer,应该放入不同的Scene里显示.
    // 而这个问题,在发现CCMultiplexLayer的使用后,才得以真正理解.
    // 利用switchTo方法,可以改变激活显示的Layer,在Scene里改变显示的Layer
    CCMultiplexLayer *layer = [CCMultiplexLayer layerWithLayers: [Layer1 node], [Layer2 node], [Layer3 node], [Layer4 node], nil];
    [scene addChild: layer z:0];
    [window makeKeyAndVisible];
    [[CCDirector sharedDirector] runWithScene: scene];
}
//以下省略了大量代码
@end

 

2.-----------------------

#import "Layer1"

 

 

@implementation Layer1
-(id) init
{
 

  if( (self=[super init])) {
   
        //设置默认的菜单项字体属性
        [CCMenuItemFont setFontSize:30];
        [CCMenuItemFont setFontName: @"Courier New"];

        //1*********创建第一个菜单项方法
        //这个菜单项完全使用精灵完成.

        //与其说是菜单项,不如说是个按钮,它像按钮一样,提供普通状态,点中状态和禁用状态三种不同状 态下需要显示的Sprite
        //并且,与UIButton类似的,点击事件通过对target的回调方法来实现.
        CCSprite *spriteNormal = [CCSprite spriteWithFile:@"menuitemsprite.png" rect:CGRectMake(0,23*2,115,23)];
        CCSprite *spriteSelected = [CCSprite spriteWithFile:@"menuitemsprite.png" rect:CGRectMake(0,23*1,115,23)];
        CCSprite *spriteDisabled = [CCSprite spriteWithFile:@"menuitemsprite.png" rect:CGRectMake(0,23*0,115,23)];
        CCMenuItemSprite *item1 = [CCMenuItemSprite itemFromNormalSprite:spriteNormal selectedSprite:spriteSelected disabledSprite:spriteDisabled target:self selector:@selector(menuCallback:)];
       
        //2********创建第二个菜单项方法
        //这个菜单项与第一个类似,不同之处是直接使用图片完称,比精灵更简洁.

        CCMenuItem *item2 = [CCMenuItemImage itemFromNormalImage:@"SendScoreButton.png" selectedImage:@"SendScoreButtonPressed.png" target:self selector:@selector(menuCallback2:)];

        //3*********创建第三个菜单项方法
        //这个菜单项使用的是文本Label方式

        //值得一提的是,cocos2d提供了超级方便的自定义字库调用方法.
        //如下方法中,设置好字库文件,并且以ascii字符排序顺序定义好字库的初始字符,就可以使用 字库创建文本Label.
        //以label方式创建的菜单项,会自动以点击放大作为菜单的操作效果来处理.
        //如果要求护理特别特殊的点中效果,也可以继承CCMenuItem之后复写selected方 法来实现
        CCLabelAtlas *labelAtlas = [CCLabelAtlas labelAtlasWithString:@"0123456789" charMapFile:@"fps_images.png" itemWidth:16 itemHeight:24 startCharMap:'.'];
        CCMenuItemLabel *item3 = [CCMenuItemLabel itemWithLabel:labelAtlas target:self selector:@selector(menuCallbackDisabled:)];
        item3.disabledColor = ccc3(32,32,64);
        item3.color = ccc3(200,200,255);
     
        //4*********** 创建第四个菜单项方法

　　  //这是一个纯文本的菜单项.

        CCMenuItem *item4 = [CCMenuItemFont itemFromString: @"I toggle enable items" target: self selector:@selector(menuCallbackEnable:)];
       
        // 5***********创建第五个菜单项方法.
        // 这也是一个使用文本配合字库文件创建的菜单项.
        // 不同的是,这里使用了fnt格式的字库描述文件.关于fnt格式的字库描述文件,我们今后再做详细研究.

        CCBitmapFontAtlas *label = [CCBitmapFontAtlas bitmapFontAtlasWithString:@"configuration" fntFile:@"bitmapFontTest3.fnt"];
        CCMenuItemLabel *item5 = [CCMenuItemLabel itemWithLabel:label target:self selector:@selector(menuCallbackConfig:)];
       
        // 6*************创建第六个菜单项方法
        // 这是一个最普通的文本菜单项,但是它搭配了一个动画效果.文本颜色,会一直变化

        CCMenuItemFont *item6 = [CCMenuItemFont itemFromString: @"Quit" target:self selector:@selector(onQuit:)];
   
        id color_action = [CCTintBy actionWithDuration:0.5f red:0 green:-255 blue:-255];
        id color_back = [color_action reverse];
        id seq = [CCSequence actions:color_action, color_back, nil];
        [item6 runAction:[CCRepeatForever actionWithAction:seq]];

        //组合菜单******** 使用上述所有菜单项,构造菜单.
        CCMenu *menu = [CCMenu menuWithItems: item1, item2, item3, item4, item5, item6, nil];
        // 将菜单居中对齐
        [menu alignItemsVertically];
       
    
        // *****************给菜单制作一个展现效果.
        // 以下的算法,实现了菜单项交叉从左右飞入的效果,还是很酷滴.
        // 关于cocos2d各种动画效果的使用,我觉得有必要单独开一篇学习笔记来学习,今天就先略过吧.
        CGSize s = [[CCDirector sharedDirector] winSize];
        int i=0;
        for( CCNode *child in [menu children] ) {
            CGPoint dstPoint = child.position;
            int offset = s.width/2 + 50;

                                       period: 0.35f]
            ];
            i++;
        }

        //将第三个菜单项设为禁用,用于演示toggle菜单项的功能
        disabledItem = [item3 retain];
        disabledItem.isEnabled = NO;

        [self addChild: menu];
