The document provides step-by-step instructions for creating a blinking eye animation for a character in Flash. It describes how to extract the eyes from the character file, create a new blinking eye animation file, and insert the blinking eye symbol back into the character file so that the eyes blink when the animation is played. Key steps include separating the eyes, building frame-by-frame animations of open and closed eyes, turning it into a symbol, and placing the symbol in the character file to trigger blinking. The process allows animating eye blinking without having to manually redraw the eyes for each frame.
