Checking if all OPFOR is dead?

[AlxPachino 10]

Right now I'm trying to create an objective based upon the number of OPFOR left. In my case, I'd prefer all of the OPFOR to be eliminated triggering that objective to be completed. I am very new to arma editing so I don't have much of a clue, but I have been doing little stuff here and there. I would be delighted if anybody could point me in the right direction into doing this.

place a trigger with opfor not present and it will activate when all is either dead or not inside trigger area for opfor.

or this one is for all units, no matter where on the map:

if ( ({(side _x) == east} count allUnits) == 0 ) then {
  hint "no east units is alive";
};

this one is for individual groups.

if ( ({alive _x} count units groupname) == 0 ) then {
  hint "none in the group is alive";
};

this one is for array/list with any unit inside.

if ( ({alive _x} count [unit1,unit2,unit5,unit12]) == 0 ) then {
  hint "none in list is alive";
};

So do I place if

( ({alive _x} count [unit1,unit2,unit5,unit12]) == 0 ) then {

hint "none in list is alive";

};

in the trigger?

Just make a trigger and set the size for axis A and B to like 10000, and then select opfor in the drop down box and then click the button "not present." this will activate the trigger when there aren't any opfor in the trigger area

Thanks guys. I'm a noob when it comes to scripting, but I can C++. Wierd ain't it?

So do I place if

( ({alive _x} count [unit1,unit2,unit5,unit12]) == 0 ) then {

hint "none in list is alive";

};

in the trigger?

You would put the ({alive _x} count [unit1,unit2,unit5,unit12] == 0) part in the condition field and the (hint "none in list is alive") part in the activation field. You would not use "then" ("then" is only necessary for if statements in scripts; condition fields in the editor just assume that syntax), and the parenthesis are not necessary.

lol I have that too with an other scripting language (lsl2), took me several years to get the hang of that, with arma scripting it's starting over from scratch again. Thank god there is a helpful community :)

I thought I'd add onto this thread as it had a great title for what I am trying to do. Here's the situation:

I have a BLUFOR base that will be attacked by randomly spawned groups of 24 OPFOR. What I need is a trigger to call the spawn. What I am thinking is that I never want more than 72 OPFOR on the map. I've scripted the spawning, but I need help with the trigger.

I was thinking of a trigger that counted the number of AI OPFOR on the map and when the number went to ~50 or so it would fire off the script, spawning another 24.

Any ideas?

Thanks,

Untested but try this as your condition line:

 
({(side _x) == east} count allUnits) <= 50

Make sure the side of your OPFOR is east or adjust accordingly.

[eLectryx 10]

Well, it fired it off on map start which is good. I got my first 24. But it only fired the once. (I changed the trigger to Repeatedly) How long in between checks?

[loyalguard 15]

If you mean how often the trigger checks the condition, it will do so most likely every frame.

[eLectryx 10]

Right. So it only fired off the once. I have it set to BLUFOR Present, Repeatedly with a radius of the entire map.

[loyalguard 15]

No need for a detection type or radius. Try taking out.

[eLectryx 10]

Ok, done. Still just fires the once. (Thanks for your help btw)

You can try this also mate...

Create a file called.... ummm.... "topup.sqf" in your mission folder.

Put this in it:-

private ["_i","_cnt"];

while {alive player} do {
_cnt = {(side _x) == east} count allUnits)};
if(_cnt <= 50) then {
	for "_i" from 0 to (72 - _cnt) do {
		[color="Red"]//spawn unit here... add your own code[/color]
		sleep 0.01;
	};
};
sleep 30;  [color="Green"]//check every 30 seconds[/color]
};

Execute this from anywhere at mission start. You can simply call it from your players init with:-

nul = [] execVM "topup.sqf";

No need for a trigger.

Untested by the way!! If it doesn't work you'll get the idea I'm sure.

There may be a conflict in the trigger parameters that I cannot see. Try placing a new trigger, said it to repeating, enter the condition code that I gave you , and put in your on activation code. If that still does not work, it may be easier to do this in the script like twirlys

[eLectryx 10]

Thanks for all the help fellas. I tried the trigger a couple times, can't see what the issue is. I just wrapped up my spawn script in the loop from Twirly and it works great. Thanks again.
