Name a unit, then use that name in trigger activation

[Petethegoat 10]

_this disableAI "MOVE"; 

_trg = createTrigger["EmptyDetector", getPos _this];
_trg setTriggerStatements["this", "[b][color="#B22222"]_this[/color][/b] enableAI 'MOVE'", ""];

This is how my code would ideally look. This doesn't work though, because the created trigger can't use the _this variable when it's activated because of scope.

I planned to solve this by giving each unit a random vehicleVarName in the script, and then using that name in the trigger, but I can't get a static var name version of the random name I give each unit.

What I need is a way for multiple created triggers to point at specific units, without manual setup in the editor. I want something equivalent to naming a unit in the editor, and then using their name within a trigger.

e:

Here's my non-functional attempt:

pg_globalName= str random 100000;
_unit setVehicleVarName pg_globalName;

_trg setTriggerStatements["this", "missionNamespace getVariable pg_globalName enableAI 'MOVE';", ""];

I'm not totally sure why this doesn't work.

e:

Here's my original script in full (with the scope issues)

_unit = _this select 0;
_enemy = _this select 1;   //"EAST" "WEST" "GUER" "CIV" "ANY"
_stance = _this select 2;   //"UP" "DOWN" "Middle"
_range = _this select 3;   //trigger radius, in meters
_unit setUnitPos _stance;
_unit disableAI "MOVE"; 
_trg = createTrigger["EmptyDetector", getPos _unit];
_trg setTriggerArea[_range, _range, 0, false];
_trg setTriggerActivation[_enemy, "PRESENT", false];
_trg setTriggerStatements["this", "_unit enableAI 'MOVE'", ""];

e:

Solved this by not using triggers at all. Here's the finished script:

_unit = _this select 0;
_enemy = _this select 1;	//"EAST" "WEST" "GUER" "CIV" "ANY"
_stance = _this select 2;	//"UP" "DOWN" "Middle"
_range = _this select 3;	//trigger radius, in meters
_unit setUnitPos _stance;
_unit forceSpeed 0;

_quit = false;
while{!_quit} do
{
sleep 1;
_nme = _unit findNearestEnemy _unit;
if(_unit distance _nme < _range) then
{
//	_unit enableAI "MOVE";
	_unit forceSpeed -1;
	_quit = true;
}
}

Solved.

You should attach the unit to the trigger with triggerAttachVehicle

[Petethegoat 10]

To clarify, I need the trigger to activate when BLUFOR are present, which rules that out for me (so far as I'm aware).

That's not what you wrote in the OP.

Uh, right. I need both at once.

Here's my original script in full (with the scope issues)

_unit = _this select 0;
_enemy = _this select 1;   //"EAST" "WEST" "GUER" "CIV" "ANY"
_stance = _this select 2;   //"UP" "DOWN" "Middle"
_range = _this select 3;   //trigger radius, in meters
_unit setUnitPos _stance;
_unit disableAI "MOVE"; 
_trg = createTrigger["EmptyDetector", getPos _unit];
_trg setTriggerArea[_range, _range, 0, false];
_trg setTriggerActivation[_enemy, "PRESENT", false];
_trg setTriggerStatements["this", "_unit enableAI 'MOVE'", ""];

So the OP is correct, but I need it without using triggerAttachVehicle, ideally. I suppose I could not use triggers at all, and just write the activation myself.

Im curious how to set a trigger to fire when one unit is present. Say that unit is named s1. how would I setup the trigger?

Petethegoat, this should pass the name of the unit to a trigger

_unit = _this select 0;
_enemy = _this select 1;   //"EAST" "WEST" "GUER" "CIV" "ANY"
_stance = _this select 2;   //"UP" "DOWN" "Middle"
_range = _this select 3;   //trigger radius, in meters
_unit setUnitPos _stance;
missionnamespace setvariable ["unitname",_unit];
_unit disableAI "MOVE"; 
_trg = createTrigger["EmptyDetector", getPos _unit];
_trg setTriggerArea[_range, _range, 0, false];
_trg setTriggerActivation[_enemy, "PRESENT", false];
_trg setTriggerStatements["this", "(missionnamespace getvariable 'unitname') enableAI 'MOVE'", ""];

or you can make the name work like any other named unit, just pass the name to the script

null=[this,"west","down",20,"whatever"] execvm "trigtest.sqf"

_unit = _this select 0;
_enemy = _this select 1;   //"EAST" "WEST" "GUER" "CIV" "ANY"
_stance = _this select 2;   //"UP" "DOWN" "Middle"
_range = _this select 3;   //trigger radius, in meters
_name = _this select 4; // name the unit

_unit setUnitPos _stance;

_unit setVehicleVarName _name;
call compile format["%1 = _unit", _name];

_unit disableAI "MOVE"; 
_trg = createTrigger["EmptyDetector", getPos _unit];
_trg setTriggerArea[_range, _range, 0, false];
_trg setTriggerActivation[_enemy, "PRESENT", false];
_trg setTriggerStatements["this", "whatever enableAI 'MOVE'", ""];

Here's my non-functional attempt:

pg_globalName= str random 100000;
_unit setVehicleVarName pg_globalName;

_trg setTriggerStatements["this", "missionNamespace getVariable pg_globalName enableAI 'MOVE';", ""];

I'm not totally sure why this doesn't work.

Your problem is that you're passing the value of pg_globalName (an object) to the getVariable command instead of the name of the variable. you need missionNamespace getVariable "pg_globalName";

Also, regular assignment uses the mission namespace, so

pg_globalName = _unit;

and

pg_globalName enableAI "MOVE";

will do.

And if you need to just detect the distance in a circle, it's easier to just script it yourself, instead of relying on a trigger.
