Subclassing CCNode question

HI

I am beginning to develop a new game using cocos2D.

The game I am designing will contain enemies which will spawn on the screen, each enemy is made up of multiple images (feet, body, head, arms etc...) I thought the best way to do this would be to subclass CCNode and in the -(id)init method create a CCSpriteSheet which will have each of the separate body part sprites added to it. This (as i understand) will reduce the number of drawing calls made.

The plan is then whenever a new enemy is required the game allocates and initialises a new instance of my subclassed CCNode.

Is this the right way to go about things or should I do it another way?

Thanks

Better would be to initialize all the enemies you need while loading your level, put them in a structure (array for instance) and add them to the scene when you need them, or use the visible property to hide/show them.

If there is only one spritesheet for all the parts, I would initialize the spritesheet, add it to the scene and then add all the nodes to the spritesheet. The parts need to be ancestors (child, grandchild and so on) of the spritesheet to take advantage of the batch draw call.
