The wiki (https://community.bistudio.com/wiki/forEach) just isn't making sense for me. So I'm trying to have multiple alarms going off without having to type a while script for each alarm so I tried to do this

_value = 1;
while {_value > 0} do {
sleep 1.7;
say3D "alarm_1";
} forEach [Alarm1, Alarm2, Alarm3, Alarm4, Alarm5];

Then I thought maybe it thought that my Alarm 2 was trying to define a group or something since thats how the wiki shows it so I changed it to this

_allAlarms == Alarm1, Alarm2, Alarm3, Alarm4, Alarm5;
_value = 1;

while {_value > 0} do {
sleep 1.7;
say3D "alarm_1";
} forEach _allAlarms;

but that didnt work.
I also tried the

_allAlarms = Alarm1...

with just the 1 equals sign but that didn't work either.
And that script is activated by a trigger to make it simple.

2 equals is for comparison, 1 equals is for assignment.

You need to wrap things in brackets to create arrays --> [var1, var2].

That's not the syntax of say3D, you need an object as a sound source.

You can just use the true value in while.

You need a separate pair of braces for forEach.

I'm assuming the Alarm variables are objects that are supposed to be the sound sources.

I thought the forEach was what defined the object for say3D; the Alarm1, Alarm2...are the names for my objects. Also do you have to have the

do {
{
}
};

or can you just do

do {
script;
} forEach;

That worked though, thank you

It defines the current element as the _x variable, it doesn't magically apply it though. Also as I told you, and as I showed in my example, yes yo do need separate braces for each of them.

EDIT: Are you thinking that you need while for the forEach to loop? forEach is a loop by itself, so you can just remove the lines 1 and 6 from the code I posted and it will still iterate (loop) through every element of the array.

Wait so if I have a trigger set to execute that script then all I have is

{
        _x say3D "alarm_1";
        sleep 1.7;
    } forEach [Alarm1, Alarm2, Alarm3, Alarm4, Alarm5];

and the alarm sound will play on a continues loop even if I leave the trigger area?

If that's the case you'd still want while. You haven't fully explained what you're exactly trying to do. Your "alarm_1" sound is 1.7 seconds long right?

If you post the above in a triggers ON ACT. field, it will play the sound on all Alarms while the trigger is activated.

So I have 5 alarm pole objects (from the CBA addon I think) around an AO and I have a trigger near a radio tower set to activate if BLUFOR units are detected by OPFOR inside the trigger area. Then when the trigger is activated is executes Alarm.sqf which is the script that I had trouble with on this post. I used sleep so that there are pauses between the alarm sound instead of it just playing the sound instantly over and over so it just sounds like a long beep. The alarm_1 is a sound file that I pulled from the Addons folder in arma 3 and put in the mission folder because I couldn't figure out how to call on it from the description.ext. But with this

while {true} do {
{
sleep 0.3;
_x say3D "alarm_1";
} forEach [Alarm1, Alarm2, Alarm3, Alarm4, Alarm5];
};

it all worked. I just didn't know you had to have that variable before say3D and those extra {}. Also I wanted the alarm to stay on even if I leave the trigger area. I'm not sure if triggers turn to false when you leave or if you go in once then they stay true so that's why I thought I had to put the while script in there. So that the sound wont stop until the mission ends.

The one thing that didn't go how I expected was that the alarms play in order so alarm 1 will play, then after 1.7 sec alarm 2 etc. But I fixed that by setting the sleep to 0.3 so that each alarm only has a short pause. But technically they still play in order but their spread out between about 1km so it still sounds ok.

If you want I could create a sample mission, I think you would need CBA though for the objects that I placed.

Well, you can get sounds from addons, just need to put an '@' symbol before it. I answered to your other post about that.

The alarm_1 sound wasn't in an addon per-say. It was in THE arma 3 addons folder. I think that folder comes with the vanilla game, though im not 100% sure about that. Anyway, I tried to use the @ for it like this

"@sounds_f_sfx\alarm.wss"

but that didn't work so I just copied and pasted it into a sounds folder in the mission folder and did

"sounds\alarm.wss"

and that worked.
And thats all in the description.ext
