同步里面CCAnimation帧进行了cocos2d 2.x的声音* [英] Syncing sounds with frames inside CCAnimation for cocos2d 2.x*

问题描述

如何将同步与动画（CCAnimation）

How would I sync sound effects with an animation (CCAnimation)

        NSMutableArray* animationframes = [NSMutableArray array];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime01.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime02.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime03.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime04.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime05.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime06.png"] delayUnits:1 userInfo:nil] autorelease]];
        CCAnimation* animation = [CCAnimation animationWithAnimationFrames:animationframes delayPerUnit:0.09 loops:1];

我可以以某种方式加入callblock到animationframes阵列？

Can I add a callblock somehow to the animationframes array?

或者，如果CCAnimationFrame有当它激活一个可选的回调/委托它可以工作。

Or it could work if a CCAnimationFrame had a optional callback/delegate for when it's activated.

推荐答案

好吧，我们所要做的是：

Ok all we have to do is:

1. 观察通知CCAnimationFrameDisplayedNotification。
   这就是所谓的上是动画精灵。

1. Observe the notification CCAnimationFrameDisplayedNotification. It's called on the sprite that is animated.

为了使
通知要被广播，字典将需要添加
到要挂接到CCSpriteFrame。我添加了一个的NSDictionary
包含每个精灵的spriteframename所有spriteframes
因为我需要挂钩所有的人，但我猜可能词典
为空好，只是没有无。

    animationframe = [[[CCAnimationFrame alloc] initWithSpriteFrame:[cache spriteFrameByName:str] delayUnits:1 userInfo:nil] autorelease];
    animationframe.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:str, @"spriteframename", nil];
    [animationframes addObject:animationframe];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(frameupdatedinbootanimation:) name:CCAnimationFrameDisplayedNotification object:NULL];

然后抓住它

-(void)frameupdatedinbootanimation:(id)hmm {
    NSLog(@"frameupdatedinbootanimation: %@", hmm);
    Do something here
