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:16itemHeight: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.
