delete all units inside a trigger area

[nettrucker]

Hi
can someone help me out with this. I need all units in a trigger area deleted once the player is distant from the trigger. i did a search but didn't find anything.
What is the right syntax? I know the deletevehicle command, but I need everything in the trigger area to be deleted.
( deleteVehicle_x) forEach units thisList . . . I tried this but it gave me an error message. Can someone tell me the right syntax?
Any help is really appreciated.
thanks in advance

The above syntax is correct, except for the fact you need to use curled braces {} for the forEach, and you don't need to use the units command (units is only used in conjunction with groups):

Code: [Select]

{deleteVehicle _x} forEach thisList

Remember to set the trigger activation to "Anybody", otherwise it'll just delete the units of the side specified.

Hi wolfrug
thanks for your swift reply mate. I checked it and it worked right away but I'm still stuck maybe I should have explained myself a little bitter better and more precisely in the first message. Since the player is moving away from the trigger1 area where all units are supposed to be deleted I need this delete trigger1 to be activated by another trigger2 as a condition. Player reaches the new trigger2 area so the former trigger1 area will delete all units inside range.
I set trigger1
condition:  delete
activation: {deleteVehicle _x} forEach thisList

trigger2 - activated by player
condition: this
activation: delete = true

but it doesn't work.
any ideas?
thanks

If you're sure you've set up the triggers correctly, the problem may lie in your variable definition: it's always a good idea to first define a variable before using it (i.e., by giving it some value such as delete = false). So try putting somewhere (in your init.sqf/sqs preferably, but the Player unit's init field works fine for tests and such too) delete=false to declare that variable: it might work then!  Also, if you want to see if there's something wrong with the script you've written or something wrong with the trigger's activation, add a hint to the other trigger, something like: hint "Trigger started!"; to make sure it's at least triggered.

Beware the anybody type triggers, you might end deleting also gamelogics vital for your game. Also, if you delete a vehicle, its crew will be "ejected" from it. So, for each vehicle you should take care to remove its crew first.

I havent tested nested foreach, it is up to you to try it:

Code: [Select]

{if (typeOf _x != "logic") then {{deleteVehicle _x} forEach crew _x;deleteVehicle _x};} forEach thisList

Hi Mandoble
Thanks for your help. I'll try that one too. well what i want to achieve is simply deleting units and objects in the trigger area to free ressources for the 2nd part of the mission so it won't be causing lag. i need simply to shift place in the mission. At a certain point all units in trigger1 aren't neccessary anymore and therefore i need them deleted.
I try to use the snippet you suggested now.
thanks for your reply

EDIT:

Both solutions worked perfectly thanks a lot.

Although Mandoble's care about logics is wise, it only protects the "logic" found in vanilla Arma. Since many addons contain derived logics, I think you'd be better protecting all types of logics:

Code: [Select]

{if (not (_x isKindOf "logic")) then {{deleteVehicle _x} forEach crew _x;deleteVehicle _x};} forEach thisList;

Hi everybody

sorry for digging up this old topic but I have still some issues with this. I did some extensive testing on the syntax. It will delete all units still alive when the trigger gets activated but dead units will remain. I need also the dead units to be removed but I really don't know how to implement this condition in the syntax of mandoble or spooner.
can anybody help me out?
thanks in advance

You will not detect dead units with a trigger. Look for dead body remover scripts in the depot.

Thanks Mandoble

I found a remover script by Taurus are you referring to that one or is there something else.
Thanks
