on idle
Syntax
on idle
statement(s)
end
Description
System message and event handler; contains statements that run whenever the movie has no other events to handle and is a useful location for Lingo statements that you want to execute as frequently as possible, such as statements that update values in global variables and displays current movie conditions.
Because statements in on idle
handlers run frequently, it is good practice to avoid placing Lingo that takes a long time to process in an on idle
handler.
It is often preferable to put on idle
handlers in frame scripts instead of movie scripts to take advantage of the on idle
handler only when appropriate.
Director can load cast members from an internal or external cast during an idle
event. However, it cannot load linked cast members during an idle
event.
The idle
message is only sent to frame scripts and movie scripts.
Example
This handler updates the time being displayed in the movie whenever there are no other events to handle:
on idle member("Time").text = the short time end idle
