Welcome to Stack Overflow. Can you please provide a little more information, like the error message you got? Also, have you cut down your code to just the bare essentials; in order to find a point where the code works properly? — kgdesouz, Dec 11 '13 at 22:30

you have to check the condition:

**

CCNode s = this.getChildByTag(kTagSprite);
 if(s!= null && s.isRunning()){
   s.stopAllActions();
}

**

It will work.Try this.If not place the log

You've used kTagSprite as wrong argument in addchild function. You have used addchild function as:

addchild(spriteParameter, z-orderParameter);

You need to use addchild as:

addchild(spriteParameter, z-orderParameter, spriteTagParameter);

So you need to replace:

addChild(player2, kTagSprite );

with:

addChild(player2, 1, kTagSprite );
