do When

[SSpeed]

do when

the When command

Code: Select all

when the_game_is_closed(), 24000
	exitapp

Faster, easier, more elegant than setting timers.

Code: Select all

when a_raider_is_detected()
{	fire_a_warning_shot()
	notify_the_user()
	cooldown when not a_raider_is_detected()
}

(the above code is equivalent to the code below)

Code: Select all

settimer, timer1, 1000
gosub, timer1

timer1:
	if a_raider_is_detected()
	{	fire_a_warning_shot()
		notify_the_user()
		settimer, timer1, off
		settimer, timer2, 1000
	}return
timer2:
	if not a_raider_is_detected()
	{	settimer, timer1, on
		settimer, timer2, off
	}return

and finally, le coup de grace.

Code: Select all

while internet_browser.active, 10000
when (flash_player.active and site="YouTube"), 2000
{	adjust_settings_macro()
	cooldown when not (flash_player.active and site="YouTube")
}

(which is equivalent to)

Code: Select all

settimer, timer0, 10000
gosub, timer0

timer0:
	if internet_browser.active()
	{	settimer, timer1, 2000  ; on
		gosub, timer1
		settimer, timer0, off
		settimer, timer00, 10000
	}return
timer00:
	if not internet_browser.active()
	{	settimer, timer1, off  ; off
		settimer, timer0, on
		settimer, timer00, off
	}return
timer1:
	if (flash_player.active and site="YouTube")
	{	adjust_settings_macro()  ; actions
		settimer, timer1, off
		settimer, timer2, 2000
	}return
timer2:
	if not (flash_player.active and site="YouTube")
	{	settimer, timer1, on
		settimer, timer2, off
	}return

.
Glad to share



Is it to be implemented?
perhaps Cooldown should be simpler, like making it function without a need for parameters?
edit: on second thought, I think cooldown should be implicit.

It could be implemented.
I also think that a syntax that handles events (or can be used to create value polling more easily).
Nonetheless the design you provided is probably very clunky and limited.
The second parameter seems very strange and we might be better off putting it into a function which could provide a simple polling mechanism.

There are also a lot of things that are not clear from this example.

Wouldn't this count as both an OnMessage and an #If?

Code: Select all

When WinActive(game.window) {
	Run(game.script)
	When !WinActive(game.window)
		WinClose(game.script)
}

Code: Select all

When WinExist(chrome.window) {
	Msgbox you've opened chrome
	When !WinExist(chrome.window)
		Msgbox you've closed chrome
}

I think I like this version more than the OP.
