Advanced Sling Loading

In 2 collections by duda
Advanced Ropes (Sling Loading + Towing + Rappelling)
4 items
Advanced Arma Pack

SP & MP Compatible. Full replacement for in-game sling loading.

Completely optional, but if you want to give back for any of my addons, I would greatly appreciate Donations[]!

Want more? Check out my latest mods!

Also check out my Advanced Towing and Advanced Rappelling
addons for more rope features!


- Ropes can no longer attach automatically! You need to either get out of your helicopter or have someone on the ground pick up your cargo ropes and attach them to an object.
- Helicopters support up to 3 sets of cargo ropes, depending on the size of the heli.
- Once cargo ropes are deployed, any player can go to the end of the rope and pick it up.
- Once the ropes are picked up by a player, they can be attached to pretty much every object in the game.
- Players can drop ropes if they're carrying them
- Players on the ground can detached ropes from an object
- Helicopters can lift heavy vehicles


1. Subscrive via steam or dowload latest release from
2. If installing this on a server, add the addon to the -serverMod command line option

Default Sling Loading Rules:

- Helicopters can sling load all objects
- You can't sling load locked vehicles (see settings below)
- You can't sling load in an exile safe zone (see settings below)

Notes for Mission Makers:

You can customize which classes of objects can "deploy" cargo ropes by overriding the ASL_SUPPORTED_VEHICLES_OVERRIDE variable in an init.sqf file.


This will only allow objects of class Air deploy cargo ropes.

You can customize what can and can't be sling loaded by defining the ASL_SLING_RULES_OVERRIDE variable in the init.sqf file.

[ ["Air", "CAN_SLING", "Ship"],
["Air", "CANT_SLING", "Air"]

In this example, all objects of class Air can sling load Ships but not Air.

You can allow sling loading of locked vehicles by defining ASL_LOCKED_VEHICLES_ENABLED in your init.sqf file. It defaults to false.


You can allow sling loading in an Exile safe zone by defining ASL_EXILE_SAFEZONE_ENABLED in your init.sqf file. It default to false.


**Not working on your server?**

Make sure you have the mod listed in the -mod or -serverMod command line option. Only -serverMod is required for this addon. If still not working, check your server log to make sure the addon is found.


This addon is only required on the server - is it going to slow down my server?

No - while this addon is server-side only, it installs itself on all clients without them downloading the addon. Most of the time, the towing code actually runs client-side, even though you installed the addon only on the server. Magic!

Battleye kicks me when I try to do xyz. What do I do?

You need to configure Battleye rules on your server. Below are the files you need to configure:


Add the following exclusions to the end of all lines starting with 4, 5, 6, or 7 if they contain "" (meaning applies to all values):

!="ASL_Ropes" !="ASL_Ropes_Vehicle" !="ASL_Ropes_Pick_Up_Helper" !="ASL_Cargo"


If you have any lines starting with 4, 5, 6, or 7 and they contain "" (meaning applies to all values) it's not going to work. Either remove the line or explicitly define the values you want to kick. Since the values of the variables above can vary, I don't know of a good way to define an exclusion rule.

Also, it's possible there are other battleye filter files that can cause issues. If you check your battleye logs you can figure out which file is causing a problem.

The sling actions appear when looking at a vehicle, but do nothing when I select them. How do I fix that?

Most likely your server is setup with a white list for remote executions. In order to fix this, you need to modify your mission's description.ext file, adding the following CfgRemoteExec rules. If using InfiStar you should edit your cfgremoteexec.hpp instead of the description.ext file. See for more details on CfgRemoteExec.

class CfgRemoteExec
class Functions
class ASL_Pickup_Ropes { allowedTargets=0; };
class ASL_Deploy_Ropes_Index { allowedTargets=0; };
class ASL_Rope_Set_Mass { allowedTargets=0; };
class ASL_Extend_Ropes { allowedTargets=0; };
class ASL_Shorten_Ropes { allowedTargets=0; };
class ASL_Release_Cargo { allowedTargets=0; };
class ASL_Retract_Ropes { allowedTargets=0; };
class ASL_Deploy_Ropes { allowedTargets=0; };
class ASL_Attach_Ropes { allowedTargets=0; };
class ASL_Drop_Ropes { allowedTargets=0; };
class ASL_Hint { allowedTargets=1; };
class ASL_Hide_Object_Global { allowedTargets=2; };

Really needs some commands implemented for AI controlled helicoptors. Particularly lower ropes and release cargo.

Maybe they're in already but I can't find them anywhere.

Hey duda bigfan and firstly great work on all your mods, liked and rated, just a quick question.
and its probably me being and total scripting noob.... ive been throught all the BI post and most of the post on here...tried all the combos, ["all","can_sling","all"] in the init.sqf, _min _lift =0, even set the atms mass to 0.0001, now i think i know why its not working.

im trying to lift an editor placed altis ATM (



SIZE (Width, Length, Height):



8 - TypeVehicle - Some entity added by game)

is this because the vehicle clase is structre??
and ideas??
any way around it??


MODS from steam

Any help at all would be apericated thanks again for all your work

Greetings! Great mod, however, I was wondering if there is anyway to enable sling-loading while still in the helicopter without disembarking, or is there no option for that still? Thanks for your help in advance!

I even tried this

I even tried upping this in the script ~

ASL_Rope_Get_Lift_Capability = {
params ["_vehicle"];
private ["_slingLoadMaxCargoMass"];
_slingLoadMaxCargoMass = getNumber (configFile >> "CfgVehicles" >> typeOf _vehicle >> "slingLoadMaxCargoMass");
if(_slingLoadMaxCargoMass <= 0) then {
_slingLoadMaxCargoMass = 16000;

Any suggestions?

Duda, I have an issue that I can't seem to resolve.

I have the Stallion Helis, (RHS / CUP / BASE ect. ect.) and I'm trying to have the ability to transport the RHS boat, patrol style / attack boat.

Here is my issue, R3F when you lift it it just falls off after a short time, but no Heli can lift this boat using your mod. Here is what I have in my Init file

["RHS_UH60M_MEV_d", "CAN_SLING", "rhsusf_mkvsoc"],
["CUP_B_CH53E_VIV_USMC", "CAN_SLING", "rhsusf_mkvsoc"],
["CUP_B_CH53E_VIV_GER", "CAN_SLING", "rhsusf_mkvsoc"],
["CUP_B_CH53E_USMC", "CAN_SLING", "rhsusf_mkvsoc"],
["CUP_B_CH53E_GER", "CAN_SLING", "rhsusf_mkvsoc"],
["rhsusf_CH53E_USMC_D", "CAN_SLING", "rhsusf_mkvsoc"],
["heli_transport_01_base_f", "CAN_SLING", "rhsusf_mkvsoc"],
["heli_transport_02_base_f", "CAN_SLING", "rhsusf_mkvsoc"]
