添加动画

利用软件Zwoptex制作的png和plist文件添加动画

       // 将花朵的png图片序列和plist载入场景

CCSpriteFrameCache *cache = [CCSpriteFrameCache sharedSpriteFrameCache];

[cacheaddSpriteFramesWithFile:@"Flower.plist"];

idsheet = [CCSpriteSheet spriteSheetWithFile:@"Flower.png"

capacity:60];

[selfaddChild:sheet];

// 将花朵Sprite添加到场景中

FlowerSprite *sprite = [FlowerSprite node];

CGSize size = [[CCDirector sharedDirector] winSize];

sprite.position = ccp(size.width / 2, size.height / 2);

[selfaddChild:sprite];

CCSpriteFrameCache *cache = [CCSpriteFrameCache sharedSpriteFrameCache];

NSMutableArray *frames = [[NSMutableArray array] retain];

// 构造每一个帧的实际图像数据

for (int i = 1; i <= FLOWER_SPRITE_SHEET_CAPACITY; i++) {

NSString *frameName = [NSStringstringWithFormat:@"Flower%04d.png", i];

CCSpriteFrame *frame = [cache spriteFrameByName:frameName];

[framesaddObject:frame];

}

// 使用CCAnimation和CCRepeatForever构造一个一直重复的动画

NSString *firstFrameName = [NSStringstringWithFormat:@"Flower%04d.png", 1];

idsprite = [CCSprite spriteWithSpriteFrameName:firstFrameName];

CCAnimation *animation = [CCAnimation animationWithName:@"Flower“ delay:1.0f / 30  frames:frames];

[spriterunAction:[CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:animation restoreOriginalFrame:NO]]];

// 将构造好的动画加入显示列表

[self addChild:sprite];

播放声音

使用cocos2d的SimpleAudioEngine可以很简单的播放背景音乐和音效。

1，准备工作

引入头文件：#import "SimpleAudioEngine.h"

2，播放背景音乐

[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"background.wav"];

3，播放音效

[[SimpleAudioEngine sharedEngine]playEffect:@"effect1.wav"];

4，暂停背景音乐

[[SimpleAudioEngine sharedEngine] pauseBackgroundMusic];

5，预先加载背景音乐

[[SimpleAudioEngine sharedEngine] preloadBackgroundMusic];

使用CDAudioManager来更改音乐的属性（更改属性之前必须有背景音乐在播放）

6，更改音量（音量大小从0到1）

[CDAudioManager sharedManager].backgroundMusic.volume = 1.0f;

7，循环播放N次背景音乐

[CDAudioManager sharedManager].backgroundMusic.numberOfLoops ＝ N;

8，背景音乐停止时触发事件

[[CDAudioManager sharedManager] setBackgroundMusicCompletionListener:self

selector:@selector()];
