Syntax
repeat with
counter
=
start
to
finish
statement(s)
end
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).
The Director player for Java doesn't detect mouse movements, update properties that indicate the mouse's position, or update the status of mouse button presses when Lingo is in a repeat loop.
Example
The following handler turns sprites 1 through 30 into puppets:
on puppetize repeat with channel = 1 to 30 puppetSprite channel, TRUE end repeat end puppetize
