An "Exist" variable? Does it exist?

[scajolly 14]

Okay, I just made a huge f* mistake.

Probability of Presence, if set to 100% for a variable MAN, will of course yield "alive MAN = true" so long as he's not destroyed.

Probability of Presence, if set to 0%, yields nothing in the bloody world.

Is there a command with which I can check whether or not something exists? Say I have the aforementioned MAN, what can I place in his INIT, and call in another unit's condition field, that will check that he either exists or does not exist?

PLEASE HELP :(

Check this:

not isNil "MAN"

Thank you, Kondor!

I just tried to edit the Condition lines in my .sqm (to rectify a far-ranging error on my part about !alive). The game crashed when trying to load the mission. Is a " in a condition line, in the sqm, a source for problems?

Worked it out. If you enter the SQM to make changes, an in-game " is an in-editor ""

If you aren't advanced mission maker you shouldn't manualy edit sqm file but via editor.

Yes " could be a problem. It's not trivial to put " inside a string. The easiest way to fix it is using ' instead of ".

The scripting system supports VB's way of escaping quotes... Use "" inside quotes.

onMapSingleClick "player setPos getMarkerPos ""marker1""";

As said, quotes inside quotes need special treatment. When you just type it in the editor the game deals with this for you in this special case.

isNil "VARNAME" checks if VARNAME has been defined. Once you give unit name VARNAME or once you run a command such as VARNAME = ... the isNil "VARNAME" will change from true to false. So be careful when using it, it doesn't necessarily check if the unit exists or not.

Oh, thanks for the heads up. Just to clarify, can you tell me if the following will not result in isNil "VARNAME" being true:

A trigger activates at t=0, condition "this AND isNil "VARNAME"

B trigger is set to activate at t=1, condition "this AND isNil "VARNAME"

VARNAME has not changed value after trigger A, has it? Trig A is simply a passive check. In a Schrödinger's Cat-like IT existensialist situation, we have not confirmed VARNAME to be TRUE just because we checked that it was FALSE?

Oh God this is getting philosophical.
