Not to be confused with Agent Character Animation.

An Agent Animation File (AAF) is a file format used by Microsoft Agent characters which stores character animations. Unlike most Microsoft Agent file formats, it cannot be opened directly. The only way to load an AAF file is by loading an ACF file created for Microsoft Agent 1.5 that references the animation.

Usage

While not directly the character themselves, AAF files contain character animations. They contain every different image and sound used in animation, the return animation for the animation, (if there is one) each frame in the animation and its properties such as the duration of the frame, each imaged used in the frame, the offset of each image in the frame, the mouth overlays in the frame, and where the frame is located in the animation. AAF files are important for ACF files developed in MACE 1.5 as ACF files only contain the metadata about the character.

Trivia

• Not much is known about Agent Animation Files, as there is not much documentation about characters made in Microsoft Agent 1.5.
• AAF files were the original file used for storing character animations in Microsoft Agent, but was randomly replaced with ACA in version 2.0.
  • The reason for this change is unknown, it could be either for formatting reasons, as Microsoft Agent 2.0 characters are compiled pretty differently from Microsoft Agent 1.5, or for naming convenience as most Microsoft Agent file types such as ACS, ACF, and ACD starting with the letters AC.
