Cocos-2d actions -- CCallFunc not doing anything - iphone

Question

Basically, I'm trying to animate a sprite. When moving right I want one animation to play, and when moving left another to play. Here's my code-- nothing is happening at all, the sprite is merely shown on the screen.
-(void)moveLeft{
[sprite stopActionByTag:0];
NSMutableArray *spriteFrames2 = [NSMutableArray array];
CCSpriteFrame *frame4 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft10.png"];
CCSpriteFrame *frame5 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft11.png"];
CCSpriteFrame *frame6 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft12.png"];
[spriteFrames2 addObjectsFromArray:[NSArray arrayWithObjects:frame4,frame5,frame4,frame6, nil]];
CCAnimation *anim = [CCAnimation animationWithFrames:spriteFrames2 delay:0.15f];
CCAnimate *animate = [CCAnimate actionWithAnimation:anim];
CCRepeatForever *repeat = [CCRepeatForever actionWithAction:animate];
repeat.tag = 1;
[sprite runAction:repeat];
id moveToLeft = [CCMoveTo actionWithDuration:3.0 position:CGPointMake(0, sprite.position.y)];
[sprite runAction:moveToLeft];
}
-(void)moveRight{
[sprite stopActionByTag:1];
CGSize winSize = [[CCDirector sharedDirector]winSize];
NSMutableArray *spriteFrames = [NSMutableArray array];
CCSpriteFrame *frame1 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight6.png"];
CCSpriteFrame *frame2 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight4.png"];
CCSpriteFrame *frame3 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight5.png"];
[spriteFrames addObjectsFromArray:[NSArray arrayWithObjects:frame1,frame2,frame1,frame3, nil]];
CCAnimation* anim = [CCAnimation animationWithFrames:spriteFrames delay:0.15f];
CCAnimate* animate = [CCAnimate actionWithAnimation:anim];
CCRepeatForever *repeat = [CCRepeatForever actionWithAction:animate];
repeat.tag = 0;
[sprite runAction:repeat];
id moveToRight = [CCMoveTo actionWithDuration:3.0 position:CGPointMake(winSize.width, sprite.position.y)];
[sprite runAction:moveToRight];
}
-(id) init
{
if( (self=[super init])) {
[[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:#"KnightImages2.plist"];
sprite = [CCSprite spriteWithSpriteFrameName:#"KnightSpritesRight6.png"];
sprite.position = ccp(240, 180);
[self addChild:sprite];
id actionSequence = [CCSequence actions:[CCCallFunc actionWithTarget:self selector:#selector(moveRight)],[CCCallFunc actionWithTarget:self selector:#selector(moveLeft)], nil];
CCRepeatForever *repeatForever = [CCRepeatForever actionWithAction:actionSequence];
[sprite runAction:repeatForever];
}
return self;
}

The way you've set this up is that the following happens, frame by frame:
Frame 1
execute moveRight
execute moveLeft
Frame 2
execute moveRight
execute moveLeft
Ad infinitum.
Since you're starting the animation all over every time you call moveRight or moveLeft, nothing really happens. You need to wait some time before running another animation for it to actually play. You can use the CCDelayTime action for this:
id actionSequence = [CCSequence actions:
[CCCallFunc actionWithTarget:self selector:#selector(moveRight)],
[CCDelayTime actionWithDuration:2],
[CCCallFunc actionWithTarget:self selector:#selector(moveLeft)],
[CCDelayTime actionWithDuration:2],
nil];
