Make unit activate repeatable trigger only once?

[Taylor1984 14]

Hi!

 

Is there a way of preventing a unit from activating a repeatable trigger more than once? I still want the trigger to be able to activate when other units enter it afterwards.

 

Thanks

So, you don't want it to activate again for that specific player who has already triggered it?

Yeah, of course. Create an array of units that already activated it and add a condition that units that can activate it can't be in said array.

Okay. Something like:

Not tested!

someArr = [];

someArr pushBack player;

if !(player in someArr) then
{
	// do whatever...
};

someArr pushBack (name player);

if !(name player in someArr) then
{
	// do whatever...
};

Alternative to creating an array would be to use setvariable/getvariable to tag the Unit.

Cond

{!(_x getvariable ["trig",false])} count thislist >0

 

On Act

{_x setVariable ["trig",true]} foreach thislist

 

Probably not the best method but it did work for me.

Thanks, it worked :)

Trigger script commands are EL( local effect only ). So if you change an editor placed trigger at runtime( e.g through initPlayerLocal.sqf ) it will only apply to the trigger on the machine you made the changes from.

You can for instance take a reference to an editor placed trigger and change its Activation to "VEHICLE" and Repeatable to False, then add the local client( player ) as the attached vehicle.

The trigger will then only activate for this client, by this client, once.

//initPlayerLocal.sqf

params[ "_player" ];

//Wait for mission to start
waitUntil { time > 0 };

//Get a reference to the editor placed trigger
_trigger = NameGivenToTriggerInEditor;

//Reassign it as active to the attached vehicle only, set unrepeatable
_trigger setTriggerActivation [ "VEHICLE", "PRESENT", false ];
//Set local player as triggers attached vehicle
_trigger triggerAttachVehicle [ _player ];

Wouldn't it suffice to delete the trigger locally after it was activated?
