   Hello, all. I have a dumb problem with sprite rotation. According to documentation, I wrote the next:

   id rotateAction = [CCRotateBy actionWithDuration:4 angle:360];
   [sprite runAction:rotateAction];

   but...nothing. I run the console and get messages:
   cocos2d: deallocing <CCRotateBy = 019B1BA0 | Tag = -1>
   cocos2d: deallocing <CCRotateBy = 01958460 | Tag = -1>

   CCRotateBy instance was deallocing, but visually sprite was not rotated. Can anybody say what happens? Thanks for participation.

   well from first look at your code... a 360 degree rotation is 1 full turn, so it shouldnt appear any different. Did you try any other rotation angles?

   Yes, I tied to set different rotation values, the same effect. May be I show not all needed information... I wrote that code in scene class in init method and all worked fine. I think my problem connected with something else. I defined some wrapper classes for box2d objects and some others and pass the pointer on sprite between a few objects. In one of this objects I try to set sprite rotation.

   inhibitor,

   Just to make it a bit easier on yourself to see what is going on, you might to try wrapping the action in a CCRepeatForever so it keeps running.

   Thanks for answers. I finally fix the problem, but don't understand why it happens. I connect cocos2d sprite with box2d body and assign userData pointer to sprite. I commented this line and now all works fine. Why, I don't know )).

   First make sure that the box2d body is not trying to set the rotation also.
   And I have found that the sprite's rotation property must be set to 0 for CCRotateBy to work.
