I believe that Zeus posted this same question: What are the units of starcraft, AOE, Warcraft, etc. called? How does one go about creating them? Don''t go into detail, I just want to know if they did something like draw some pictures them stick them in a sequence, or something else along those lines. And were they models that they used in games like Black and White, Battle Realms, and Empire Earth? They are really small, and I have no idea how to recreate those... Thanks to anyone who responds.

Are you talking about sprites?

In 2D programs such as Warcraft, the animation is created by put a sequence of images.

In 3D programs such as Black and White, are you talking about all the small people?
They are just low polygone 3D objects exactly like the creature. They probably keep all the data for each personne together in an array.
