   I've been working on my first game with Cocos2D, and I've come across a question that Google doesn't seem to have an answer for. Is cocos2D like Flash, where the camera is fixed and in order to scroll a world you must move all the background things around, or is there a way to move the cocos2D camera (keep everythings X and Y coords static, just add to the camera's X and everything scrolls to the right)? It stands to reason that if Cocos2D is based in OpenGL there would be a way to do that.

   If it helps anyone the APIs have a class called Camera, but the APIs are pretty unclear, and they say that the camera will be overridden by anyone setting the position variables.

   We do this on our scene node:
   [self.camera setCenterX:newCameraPosition.x centerY:newCameraPosition.y centerZ:0];
   [self.camera setEyeX:newCameraPosition.x eyeY:newCameraPosition.y eyeZ:415];

   yes my map bigger than iPhone screen. not really big (15 x 10) screen size. i use the above code to move the map but it move reversely. what value do i need to hange here? Im in landscape mode:

   currTouch is a currentTouchLocation.

   I update My camera and call updateCamera function each time I move the screen by implementing the ccTouchesMoved method:

   -(void)updateCamera
   {
   [self.camera setCenterX:currTouch.x-80 centerY:currTouch.y+80 centerZ:0];
   [self.camera setEyeX:currTouch.x-80 eyeY:currTouch.y+80 eyeZ:415];

   }

   but it move reversely.
