I have an idea for an animation, I need to know how to write it in "animation language". Is there a special fomat that is used for animation script writing?

Hi,
You might have to buy one of the books, suggested by many sites. Here is a link for some good information:

It's called "standard industry format", and is available in book form. If you wish to see the above link, then scroll down about half way, to "Animation Format".
