The following example performs a similar action, but with decreasing numbers:
-- Lingo syntax
repeat with n = 10 down to 2
sprite(n).ink = 36
end repeat
// JavaScript syntax
for (var n=10; n>=2; n--) {
sprite(n).ink = 36;
}
In Lingo, to repeat a set of instructions as long as a specific condition exists, use the
structure.
while
In JavaScript syntax, to repeat a set of instructions as long as a specific condition exists, use the
structure.
while
For example, the following statements instruct a movie to beep continuously whenever the mouse
button is being pressed:
-- Lingo syntax
repeat while _mouse.mouseDown
_sound.beep()
end repeat
// JavaScript syntax
while (_mouse.mouseDown) {
_sound.beep();
}
Both Lingo and JavaScript syntax scripts continue to loop through the statements inside the loop
until the condition is no longer true, or until one of the statements sends the script outside the
loop. In the previous example, the script exits the loop when the mouse button is released because
the condition is no longer true.
mouseDown
In Lingo, to exit a loop, use the
In JavaScript syntax, to exit a loop you can use the term
when a condition is no longer true.
For example, the following statements make a movie beep while the mouse button is pressed,
unless the mouse pointer is over sprite 1. If the pointer is over sprite 1, the script exits the
loop and stops beeping. The
specified sprite.
-- Lingo syntax
repeat while _mouse.stillDown
_sound.beep()
if _movie.rollOver(1) then exit repeat
end repeat
// JavaScript syntax
while (_mouse.stillDown) {
_sound.beep();
if (_movie.rollOver(1)) {
break;
}
}
