createVehicle and getPos without name.

[whiskey]

I've got a group of men that I've attached and action to with this line...

Code: [Select]

{_x addAction ["Detonate Vest","detvest.sqf"]} forEach units group this;
...but the only thing my scripting challenged mind can think to put in detvest.sqf is...

Code: [Select]

bomb = "BO_GBU12_LGB" createvehicle getPos guy;

guy removeAction 0;

...but that just blows up the one unit. How do I setPos a bomb to the AI who I ordered to detonate (F#>6>1)? Without having to name 20 men and having 20 detvest#.sqf files in the mission folder.

Change detvest.sqf to (untested, but should work):

Code: [Select]

bomb = "BO_GBU12_LGB" createvehicle getPos (_this select 1);

(_this select 0) removeAction (_this select 2);
When using addAction, it automatically passes the unit the action is attached to, the unit who used the action and the action ID number to the script.  So we've used those here.

Despite making missions since CWC, being able to use and tinker with other peoples scripts or using the functions from A2/OA this stuff is still like black magic when it comes to writing my own.

What should I read to explain the whole 'this select 0' thing?

Thank you James, works perfectly.

[JamesF1]

Well, "_this" is the information (or parameters) passed to the script.  In this case, it's an array of values (the three I mentioned above).  In order to access the values in an array, we use the keyword 'select'.  The first value is '_this select 0', the second is '_this select 1' and so on...

So, if we had an array:

Code: [Select]

_myArray = [1, 4, 3, 8, 9];
To get the number 3, we'd do:

Code: [Select]

_myNumber = _myArray select 2;
To make the script above more obvious, we could do:

Code: [Select]

_parameters = _this;
_attachedTo = _parameters select 0;
_user = _parameters select 1;
_id = _parameters select 2;

bomb = "BO_GBU12_LGB" createVehicle getPos _user;

_attachedTo removeAction _id;
This has no real difference* but is just a more readable version.
* Technically it is more resource-intensive but by such a minuscule amount that you'd never notice it, even if the script was run 100 times simultaneously.

Hope that helps

Lol, you're first description made far more sense than the second.

The script works but not if the unit is in a vehicle, the bomb doesn't spawn. Looking at the Biki for if/else & vehicle commands seems to be what I need but again the syntax is beyond me, to check if he's in a vehicle and spawn the bomb at the vehicle instead....

Code: [Select]

_inVeh = if (? vehicle player != player : hint "Player is in a vehicle")

then

{bomb = "BO_GBU12_LGB" createvehicle getPos (_this select not_sure?);}

else

{bomb = "BO_GBU12_LGB" createvehicle getPos (_this select 1);};

hint str _inVeh

I can only assume that to those who script ^this^ is ugly... and broken.

so you just want to have the player have the bomb? That's your objective?

[whiskey]

In this scenario the player is a terrorist leader with 10 men under him, each of these men strapped with a bomb vest. The objective at the moment is to cause as many civilian casualties as possible with these ten men. I already have the civilian kill counter in. Eventually I hope to have a small but fully populated island where the player can pick the locations of the bombings. There will be options other than instant suicide but just tinkering really.

The problem I have above is that the setposing of the bomb doesn't work if they're in a vehicle, so I need it to setpos it to the vehicle instead (in that case).

Code: [Select]

_unit = _this select 1;
_actionID = _this select 2;
bomb = "BO_GBU12_LGB" createvehicle getPos (vehicle _unit);

_unit removeAction _actionID;

That should work, no guarantees.

When then man is not in a vehicle, the command

Code: [Select]

getPos (vehicle _unit) will just return the unit's position. Otherwise, it will return the vehicle's position.

NB: Speaking of resource efficiency, IIRC getPosASL or getPosATL is up to 10 fold faster than getPos...
