on (release) {
_root.base.helptabs._visible=!_root.base.helptabs._visible
}
Again, we’re taking advantage of that logical NOT operator, avoiding the clunkiness of using if statements to test to see if the movie clip’s visibility returns true or false before changing it. Instead, whenever the help button is clicked, the help file’s movie clip becomes the opposite of what it was before. If it was visible, suddenly it isn’t. If it isn’t visible, suddenly it is. It simplifies the script down to one line of code inside a simple on (release) handler.
