本文展示了如何使用AtlasSpriteManager进行精灵的缩放、旋转等动作操作，并演示了精灵的水平和垂直翻转功能。

例子6：（展示AtlasSpriteManager这个集合的action动作情况）
@implementation Atlas6
-(id) init
{
    if( (self=[super init]) ) {

        // small capacity. Testing resizing
        // Don't use capacity=1 in your real game. It is expensive to resize the capacity
        AtlasSpriteManager *mgr = [AtlasSpriteManager spriteManagerWithFile:@"grossini_dance_atlas.png" capacity:1];
        [self addChild:mgr z:0 tag:kTagSpriteManager];

        CGSize s = [[Director sharedDirector] winSize];

//If YES the transformtions will be relative to it's anchor point.
//精灵，标签和任何其他sizeble对象使用它有它默认情况下启用
//场景，层和其他“整个屏幕”对象不使用它，有它默认被禁用。
mgr.relativeAnchorPoint = NO;
    mgr.anchorPoint = ccp(0.5f, 0.5f);   //为中心点
    mgr.contentSize = CGSizeMake(s.width, s.height);   //设置内容的宽度和高度为整个屏


        // AtlasSprite actions
        id rotate = [RotateBy actionWithDuration:5 angle:360];
        id action = [RepeatForever actionWithAction:rotate];

        // AtlasSpriteManager actions
        id rotate_back = [rotate reverse];
        id rotate_seq = [Sequence actions:rotate, rotate_back, nil];
        id rotate_forever = [RepeatForever actionWithAction:rotate_seq];

        id scale = [ScaleBy actionWithDuration:5 scale:1.5f];
        id scale_back = [scale reverse];
        id scale_seq = [Sequence actions: scale, scale_back, nil];
        id scale_forever = [RepeatForever actionWithAction:scale_seq];

        for(int i=0;i<3;i++) {
            AtlasSprite *sprite = [AtlasSprite spriteWithRect:CGRectMake(85*i, 121*1, 85, 121) spriteManager: mgr];
            sprite.position = ccp( 90 + i*150, s.height/2);

            [sprite runAction: [[action copy] autorelease]];
            [mgr addChild:sprite z:i];
        }

        [mgr runAction: scale_forever];
        [mgr runAction: rotate_forever];
    }
    return self;
}
-(NSString*) title
{
    return @"AtlasSpriteManager transformation";
}
@end

例子7：（展示flipX:是否精灵水平翻转 flixY:是否精灵垂直翻转，可以用来制作人物运动）
@implementation Atlas7
-(id) init
{
    if( (self=[super init]) ) {

        AtlasSpriteManager *mgr = [AtlasSpriteManager spriteManagerWithFile:@"grossini_dance_atlas.png" capacity:10];
        [self addChild:mgr z:0 tag:kTagSpriteManager];

        CGSize s = [[Director sharedDirector] winSize];

        AtlasSprite *sprite1 = [AtlasSprite spriteWithRect:CGRectMake(85*1, 121*1, 85, 121) spriteManager: mgr];
        sprite1.position = ccp( s.width/2 - 100, s.height/2 );
        [mgr addChild:sprite1 z:0 tag:kTagSprite1];

        AtlasSprite *sprite2 = [AtlasSprite spriteWithRect:CGRectMake(85*1, 121*1, 85, 121) spriteManager: mgr];
        sprite2.position = ccp( s.width/2 + 100, s.height/2 );
        [mgr addChild:sprite2 z:0 tag:kTagSprite2];

        [self schedule:@selector(flipSprites:) interval:1];
    }
    return self;
}
-(void) flipSprites:(ccTime)dt
{
    id mgr = [self getChildByTag:kTagSpriteManager];
    id sprite1 = [mgr getChildByTag:kTagSprite1];
    id sprite2 = [mgr getChildByTag:kTagSprite2];

    BOOL x = [sprite1 flipX];
    BOOL y = [sprite2 flipY];

    [sprite1 setFlipX: !x];   //当前状态取反，两种状态不断的切换
    [sprite2 setFlipY: !y];
}
-(NSString*) title
{
    return @"AtlasSprite Flip X & Y";
}
@end
