cocos2d gives slow animation?

i have used cocos2d for game development.but when i use a sprite in CCLayer(inherited) to move through ccTime.but it moves very slowly.i have set in appgelegate CCDirector setAnimationInterval for (1.0/60) The code is as following:

-(id) init
{
if ((self = [super init]))
{
    danceSprite = [CCSprite spriteWithFile:@"images.png"];
    [self addChild:danceSprite];

    // position the sprite in the center of the screen
    CGSize s = [[CCDirector sharedDirector] winSize];
开发者_如何转开发    danceSprite.position = ccp(s.width/2,s.height/2); //CCSprite
    bg_pos.x = danceSprite.position.x;
    bg_pos.y = danceSprite.position.y;
            [self scheduleUpdate];
}
return self;

}

-(void) update:(ccTime)delta
 {
CGPoint pos = danceSprite.position;
bgX = pos.x;
//bgX -= 30.0;


int newX;
newX = bgX + 1.0 * GAME_SPEED_ADJUSTMENT;
pos.x = bgX;


}

GAME_SPEED_ADJUSTMENT variable/constant

to multiply with delta to get a faster movement. My start setting is always a

minimum of 10

, in your case it's 1, so I would expect it to move rather slowly.

So it looks like

newX = oldX + delta * GAME_SPEED_ADJUSTMENT

Try this first - one might also use this to increase the difficulty of the game and globally move things faster.

If this doesn't work, just come back....
