I have noticed there are many ways of animating. One of the most obvious ones (to me) is the option of having a single image file with multiple animation sprites, or multiple files each containing one sprite per animation frame.
Which option is most efficient? I personally would like to use a single image instead of multiple; but if using multiple images is more efficient; well - I would go with the most efficient method.
I am still new to animation so any additional tips are welcome :)
