nothing

Syntax

nothing

Description

Command; does nothing. This command is useful for making the logic of an if...then statement more obvious. A nested if...then...else statement that contains no explicit command for the else clause may require else nothing, so that Lingo does not interpret the else clause as part of the preceding if clause.

Example

The nested if...then...else statement in this handler uses the nothing command to satisfy the statement's else clause:

on mouseDown
	if the clickOn = 1 then
		if sprite(1).moveableSprite = TRUE then member("Notice").text = "Drag the ball"
		else nothing
	else member("Notice").text = "Click again"
	end if
end

Example

This handler instructs the movie to do nothing so long as the mouse button is being pressed:

on mouseDown
	repeat while the stillDown
		nothing
	end repeat
end mouseDown
