Objects in sleep mode

        
        var len:uint = characterArray.length;
        for (var i:uint=0; i<len; i++)
        {
            characterArray*.moveCharacter();
        }

This is how i generally run all my objects

lets say some of those characters are in a “sleep mode”. Would you just run threw the whole array anyway and let the character decide that he is asleep? that’s why i’ve been doing.
