repeat with

Usage

-- Lingo syntax

repeat with counter = start to finish

statement(s)

end repeat

Description

Keyword; executes the Lingo specified by statement(s) the number of times specified by

counter. The value of counter is the difference between the value specified by start and the

value specified by

finish. The counter is incremented by 1 each time Lingo cycles through the

repeat loop.

The

repeat with structure is useful for repeatedly applying the same effect to a series of sprites

or for calculating a series of numbers to some exponent.

While in a repeat loop, Lingo ignores other events. To check the current key in a repeat loop, use

the

keyPressed property.

Only one handler can run at a time. If Lingo stays in a repeat loop for a long time, other events

stack up waiting to be evaluated. Therefore, repeat loops are best used for short, fast operations or

when users are idle.

If you need to process something for several seconds or more, evaluate the function in a loop with

some type of counter or test to track progress.

If the stop condition is never reached or there is no exit from the repeat loop, you can force

Director to stop by using Control+Alt+period (Windows) or Command+period (Macintosh).

Example

This handler turns sprites 1 through 30 into puppets:

on puppetize

repeat with channel = 1 to 30

_movie.puppetSprite(channel, TRUE)

end repeat

end puppetize
