Writing scripts in the Script window 79
Performing common tasks
The following are ways to perform common tasks for creating, attaching, and opening scripts.
To create a frame behavior (script attached to a frame):
• Double-click the behavior channel in the frame to which you want to attach the behavior.
When you create a new behavior, the behavior receives the cast library number of the first
available location in the current Cast window.
When you create a new frame behavior, the Script window opens and already contains the Lingo
on exitFrame handler The first line contains on exitFrame, followed by a line with a blinking
insertion point, and then a line with the word
end. This makes it easy for you to quickly attach a
common Lingo behavior to the frame. To make this handler work with JavaScript syntax, replace
on exitFrame with function exitFrame() {, and replace end with }.
One of the most common frame behaviors is one that keeps the playhead looping in a single
frame. This can be useful when you want your movie to keep playing in a single frame while
waiting for the user to click a button or for a digital video or sound to finish playing.
To keep the playhead in a single frame:
• In a frame behavior, type the following statement on the line after the on exitFrame (Lingo)
or
function exitFrame() (JavaScript syntax) statement:
-- Lingo syntax
_movie.go(_movie.frame)
// JavaScript syntax
_movie.go(_movie.frame);
The Movie object’s frame property refers to the frame currently occupied by the playhead. This
statement essentially tells the playhead to "go back to the frame you are currently in."
