Use a trigger only in a certain area?

[stephen271276]

is it possible to make a trigger that is only usable in a certain area? ie a small area of town where a firefight is taking place with a radius of say 150... but when you move out of that radius the option to use the trigger via radio disappears?

Code: [Select]

_trg=createTrigger["EmptyDetector",getPos xxx];
_trg setTriggerArea[150,150,0,false];
_trg setTriggerActivation["CIV","PRESENT",true];
_trg setTriggerStatements["this", "1 setRadioMsg ""Call Radio"""];

_trg2=createTrigger["EmptyDetector",getPos xxx];
_trg2 setTriggerArea[150,150,0,false];
_trg2 setTriggerActivation["CIV","NOT PRESENT",true];
_trg2 setTriggerStatements["this", "1 setRadioMsg null"];
