Example scripts that use the attachTo command

[Big Dawg KS 6]

Before we all get carried away and start attaching shit like crazy, has anyone observed any strange side effects of using attachTo? I think it messes up AI's ability to target attached objects, they seem to just keep firing at its starting location. What about getPos on attached objects, anyone tried it?

[Nephris1 10]

Saw that but didnt get it working that way, so i supposed there wereanother one i missed:rolleyes:

Get an type script expect nothing error, by using it in the init.

GetPos should work as usual and I've never observed the AI problem.

Btw the AI do sometimes keep firing on a known position even when the target has moved (without them noticing) but tbh, I do the same thing.

Biggest issue is that attached Objects do not have collision detection.

[Big Dawg KS 6]

Yes I noticed that behaviour from AI, but I'm still not sure AI are capable of tracking attached objects with the same effiency as normal moving objects, which may or may not be related to lack of collision detection.

If I remember rightly there's something like collision detection for some vehicles like the M1A1 or the Ural. For other vehicles like the tractor I hear a collision-sound and the vehicle is damaged but it doesn't collide.

Hmm guess everyone fell in love with the AttachTo :P hehe.

Someone mentioned using it for towing... don't do it. In this specific case youre better of using setpos since a rope is somewhat flexible and with the attachto it would look like whatever is beeing towed is fixed on the end of a stick. Setpos in combination with setvelocity and velocity does a pretty decent job for this. I can post some snipplets if required.

Can I have more information about this? I want to create a good towing script. I though about using attachto with a lot of Math, but mabye you have a better idea?

[Tajin 349]

You'll need good maths in both cases. ;)

My script works like this:

_obj setVelocity [((_vel select 0)+_xdir*1.6)*_factor,((_vel select 1)+_ydir*1.6)*_factor,(((_vel select 2)+_zdir*3)*(_factor-0.3))-4];

It may look a bit cryptic at first... let me explain:

factor is an variable that I use for the length of the rope. In fact it is the deviation from the maxium length of the rope. If the distance is less, then no force will be applied to the towed object. If the distance is bigger than the length of the rope then the speed of the carrier will be added to the speed of the towed object, plus some damping.

If the distance gets too big however, the rope will break.

So the concept is rather simple and unlike normal towing scripts it can look quite realistic.

I think I'll rewrite mine sometime and finally release it one day. (unless I'm getting lazy again)

[nicolasroger 11]

thx. I don't have enought scripting experience right now to fully understand your script (specialy the variables like _vel ) but I get the basic information. I will continue to read about scripting.

By the way, your script use way less math than my initial idea so I guess I'll forget my idea lol

[Tajin 349]

The code I've postet is only an extract. Most of the math happens before. ;)

_vel is the variable in which I store the xyz velocity of the chopper.

Anyway, that line of code was only an example. Good luck with yours, holler if you need anything for it.

Damn.

Wait, I'll give you the last tested version using two files. I've merged those two files into one, but I couldn't test it at the moment so maybe I have an small bug there somewhere that I didnt notice. However, the 2-file version should work.

http://tajin.evilhosting.de/arma/cargoscript.zip

Init:

[this] execVM "c130cargo.sqf"

Ok, i'll get it out the way quick - I'm a noob. I know about <--this--> much about scripting, and i'm gettin a bit stuck with the c130 script, i've added the code to the init box on the unit, but i've obviously put the .sqf file in the wrong place because just as the mission loads i get a message saying it can't find the script. Where exactly do i need to put the .sqf file for it to work? Halp :confused_o:

[Tajin 349]

Look under "MyDocuments" there should be an "ArmA2" folder somewhere then a "missions" or "mpmissions" folder and in there are folders for each mission you're building in the editor. Put the scripts in the folder of the mission you need them for.

[mr_centipede 31]

May I ask a question, does AI soldier using attachTo command can fire their weapon? if they can how is their accuracy? is it like normal or is it like static weapons? I'm figuring it could be made with a foxhole

The Missions & MPMission folders are there but they're empty apart from the readMe :j: and i've got plenty of missions in progress in the editor. Hidden files are on, but knowing me i'm probably doing something else wrong...

[Benneb 10]

There should be two Arma 2 directories in the my documents folder.

Try looking in: My Documents\Arma 2 Other Profiles\<Your profile name>\Missions

Thats where it stores mine.

[Killy_McMurder 10]

Ok, i've got the .sqf in the correct mission folder. And the init box for the unit has the correct line in it, but it still says that the script can not be found when i first load and preview the mission... am i just screwed?lol :confused:

I don't see why it would be different your not changing the config of the unit, the only problem I can see is if the old bugs of not being able to shoot over certain objects is still about.

[Killy_McMurder 10]

Got the c130 script working, finally, Works brilliantly.

Thanks Tajin, done a great job there

[Tajin 349]

Thanks, I'm glad it works for you now. :cool:

Hi,

I've got a bunch of guys to para out of 2 ospreys. The ospreys are spawned with an sqs, as are the troops and waypoints.

Is there any way to get a humvee loaded into a C130 with the same type of script and then when it reaches a scripted waypoint execute the unload function from above or something similar?

[breeze 0]

Is there any way to make the soilders get ontop of the apc for a moveincargo command so that we can have AI scripted to do it and can it be on any of the russian equiptment??

[warpuppy 0]

hi there all

I was wondering if anyone could point me/assist me in being able to use the attachto command to load the mortar/ammoboxes into a truck that could transport them around and then unload

Any help would be much appreciated

Many thanks in advance

[breeze 0]

sqf files go in the same place that the mission does same folder

[vengeance1 50]

I tried getting the Init to work like this but it errors I was able to get it to work like this?

res=[this] execVM "c130cargo.sqf";

Great Script however lots of uses.

Just name the truck and the ammo

ammo attachto [truck,[0,0,0]]

That will be in the wrong place but see where it appears and just adjust it's position to get it into the right place using different values X,Y,Z in the attacto command.

To detach it's just

detach Ammo

place in a trigger or waypoint, To get it off the truck you may need to give it a new position.

Hi all,

The script works for me but unfortunately it stopped to work after the first respawn of the c130. :confused:

Tested on "Co_30_EvolutionUSMC_v08.Chernarus".

Any idea ?

Thx :)
