Attach a backpack

[tazmania720 16]

I have been noticing addons/missions that have some backpacks attached to the bed of the pick-up trucks. How is this accomplished? I have tried searching for "arma 3 attach backpack truck" and other ways and still can't find the answer. Also, when this is done is it able to remove the backpack from the truck so that someone can wear it? Thanks!

attachTo is what you need to attach it. You'll also need to change its direction using setDir before attaching it. Good luck finding the offset value you'll need for the backpack to be at the right location on the truck as that requires trial and error as its a complete crapshoot as to if you'll hit it dead on or not. Using addAction can attach and detach the backpack from the truck (probably will also need some way to track what backpacks are attached to the truck and how many are attached, then that'll need to be synced up to all clients in mp, which makes it a bit more complex). I don't have the time to assemble any code right now, you should try to do it on your own.

Thanks austin_medic for the reply. I'll give it a shot, but I am pretty clueless when it comes to in depth scripting.

So I have learned that attachTo does not work with backpacks. I changed the item to a toolkit and I am able to attachTo to the offroad.

I have found something called "groundweaponholder" and found a script that changes a placed object to another.

Placed a road cone and in the INIT entered:

this setpos[(getpos this select 0),(getpos this select 1),-100]; Waffe1 = "groundweaponholder" createVehicle getpos this; Waffe1 addWeaponCargo ["arifle_MX_F",1]; Waffe1 setPos [getPos this select 0,getPos this select 1,0];Waffe1 setdir 75;

The cone was changed to the rifle on the ground.

I changed the script to this:

this setpos[(getpos this select 0),(getpos this select 1),-100]; Waffe1 = "groundweaponholder" createVehicle getpos this; Waffe1 addBackpackCargo ["B_Carryall_ocamo",1]; Waffe1 setPos [getPos this select 0,getPos this select 1,0];Waffe1 setdir 75;

The cone changed to a backpack.

NOW, how do I use the attachTo command with all this? Thanks!

waffe1 = "groundweaponholder" createVehicle getpos myCar;  // use the createVehicle array syntax in future though
waffe1 addBackpackCargoGlobal ["B_Carryall_ocamo",1];

// Now attach waffe1 to vehicle;

waffe1 attachTo [myCar,[0,2,2]];

Now your backpack is attached to the vehicle

Thank you so much for this! Now how do I make the bag with the bottom down and front facing left (I know how to adjust the attachTo numbers to position it on the truck where I want)? I found setDir, and can turn it, but it does not change the other axis. I also found setVectorDirAndUp but that makes no sense to me. Thanks!

That's probably the best answer for you.

You might have to play around with the numbers but everything is in that link.

Thanks! I am looking at it now.

Guys are you serious...

It's the method of showObject or whatever

Check the virtual garage and export to your needs, or just find the command and do it that way.

Vehicle - Offroad - Backpacks, Lights, Bullbars, etc.

I have found that, but I wan't a player to be able remove the pack and use it, not just an eye candy thing.

Nah you can't do anything with those. He's not talking about unhiding an animation.

[epicgoldenwarrior 11]

mmm k sorry then.

[tazmania720 16]

Figured it out!

And used:

waffe1 = "groundweaponholder" createVehicle getpos myCar; waffe1 addBackpackCargoGlobal ["B_Carryall_ocamo",1]; waffe1 attachTo [myCar,[-1.7,-1.2,-0.48]]; waffe1 setVectorDirAndUp [[-1,0,-5],[0,0,1]];

Thanks for all the help and info!!!

hey mate could you write up a little guide on how to do this? Im not sure where to put the script you posted in the last post. I know this is almost 2 years old now but hope you can help. 

[tazmania720 16]

@stormoffires If I remember correctly I was playing around with this in the debug console, as seen in the imgur link, but you can easily add this to the INIT block of the Offroad.  Just name Offroad myCar or change "myCar" in the script to "this" removing the " of course.  Now what I didn't figure out, and maybe someone can add to this, is how to fill the bags with gear.  Enjoy!  I'm glad I was able to develop something someone else sees as useful.

Well you have a reference to the groundWeaponHolder waffe1 so you can just do a everyBackpack on it to get a reference to the backpack object.

waffe1 = "groundweaponholder" createVehicle getPos myCar;
waffe1 addBackpackCargoGlobal ["B_Carryall_ocamo",1];
waffe1 attachTo [myCar,[-1.7,-1.2,-0.48]];
waffe1 setVectorDirAndUp [[-1,0,-5],[0,0,1]];
{
	_x params[ "_backpack" ];
	_backpack addItemCargoGlobal "FirstAidKit";
}forEach everyBackpack waffle1

Thanks!  I'll play around with this.
