Checking if a person is inside a vehicle?

[OmniMax 0]

I'm having some problem with some code to check if a person is inside a static defense weapon. Whenever I run the script I crash with an error 7.

Here is the code in question:

#check
if ((assignedGunner c130_nose) == 0): Hint format["Nobody inside!"]
end

I'm assuming a null object returns 0, I just don't know syntactically what is wrong with the code.

You can use this:

if (isNull assignedGunner pod) then { 
       hint "No one inside!"; 
   } else { 
       hint format["This guy is gunning: %1", assignedGunner pod];
};

Figured it out. :)

Thank you, I skipped ARMA so I'm not sure when they abandoned the poor goto scheme of scripting or if you could always use C style braces. I never knew this and it will make life a lot easier.

If I wanted to execute the command of the activating unit of the script (command added via AddAction) and as far as the OFP days go:

_unitWithAction = _this select 0;

_activatingUnit = _this select 1;

_actionIndex = _this select 2;

So why doesn't this line of code work?

if (isNull assignedGunner pod) then { 
(_this select 1) moveInGunner pod;
   } else { 
       hint format["This guy is gunning: %1", assignedGunner pod];
};

The pod is empty yet the activating unit doesn't get moved into the empty pod. _this select because the array is made when you invoke AddAction and _ActivatingUnit already exists, correct?

EDIT: Okay, it works, but not when the action is invoked inside a vehicle, because the activating unit is whatever vehicle you're in. Wonder how to solve this one... any ideas?

Might be since _this is local, but who is calling that action from what?

If it's an action that seems to indicate that it's a player doing this, and if it's a player and a static gun, why not just have them use the default 'Get In' option?

What's the scenario for this action/gun/thingie? :)

Edit: Ahh, I see, so this is an AC-130 type thing, trying to get a gunner into an attachTo'd weapon from inside?

Ah, it isn't doing moveInGunner because it thinks the activation is the vehicle you're in and moveInGunner/moveIn series requires a soldier argument.

What I'm trying to accomplish?

Something like this:

Ever since OFP and seeing the juicy VBS and VBS2 videos, people have wanted a way to either walk in vehicles or have multiple gun positions per vehicle. So I've attached these M2s on a C130 with attachTo and it works pretty well. I haven't tested it out in multiplayer yet, though. If it works, the implications are really good for modders and such.

My game mode is simple: Two C-130s with their appropriate OPFOR/BLUFOR attached machine guns "dogfight" each other. The M2s are going to be invulnerable with an event handler, but the guys in the guns are not invulnerable (tested). If a pilot/gunner dies, he is respawned in the middle of the ocean with a corresponding trigger. That trigger moves him into his side's C130's cargo. I want the script to be able to put him on the guns outside while being in the C130's cargo.

Whichever C130 dies\runs out of fuel\ammo\crashes first loses. Simple and mindless fun and proof-of-concept.

However, I'm going to have a problem with this _activatingUnit, whoever is in the C130 and triggers the action is going to pass the C130 as the activating unit, unless you know of some work around?

I appreciate your help thus far. I'm a computer science student and I dwell in C and C++ so the data types of ARMA's engine drive me nuts and I wasn't aware you could use C like braces; but the last time I coded any script I must have been 15 and had very little knowledge of such things.

So, any work around ideas? :confused:

My first thought was to use a dialog. I setup a quick test and got it halfway working. I can EITHER get in the C-130 from outside OR get in the M119 from outside, but from inside.. nothing.

To be honest though, vehicle placement and dialogs are well above me, but here's what I got so far. Pretty sure the doGetOut isn't working properly, since it seems to stop at that point.

Update: YAY! Got it working! If you use setPos to yank the player out of the vehicle they are in, you can then immediately plop them back into the OTHER vehicle. Next up would be to make it dynamic, so instead of Player it would be whoever pushed the button.

_ok = createDialog "myPositionPicker"
exit;

Then each vehicle the plane1 and pod have:

this addAction ["Change Position", "pos.sqs"];

You'll definately want to read up on the SQF Syntax changes. :)
