BackpackOnChest - Redux

We've been having some collision issues with people being inside of vehicles and the vehicles freaking out and being sent to space when people are wearing two bags. I haven't been able to troubleshoot this further but you may want to double-check wherever ArmA handles collision.

Alternatively, this might be a conflict between Backpacks on chests and the walkable moving objects mod. It's hard to say without more concrete reproduction steps. If anyone else is having this problem, let us know.

Does this have AI support?

It is known. I have an update planned to roll-back some recent changes which made this behavior worse and handle some things I was trying to do with it differently.

When switching the backpack to chest and back it resets the radiochannels with ACRE. Is this a known bug?

Good to know and thank you.

Thanks for the help.

I just needed to write in a patch to prevent people from using the "Alternative Running" sprint mod while carrying a bag on their chest since they were able to circumvent the force-walk restriction by just doing the modded sprint (The mod: https://steamcommunity.com/sharedfiles/filedetails/?id=2198339170)

I just had to change the path to the XEH_preinit.sqf to my own and included this in the beginning to patch the exploit, code below worked as needed as a simple workaround

if (!isNil {player getVariable ["bocr_main_chestpack", nil]}) exitWith {
systemChat "You are unable to sprint with a bag on your chest.";
};

I almost had it, wasn't totally sure about `_main_` being there, and couldn't be arsed to boot the game to try.

I'd recommend using `isNil` directly as of 'Arma 3' v2.18:
_unit isNil "bocr_main_chestpack"

instead of

isNil {_unit getVariable ["bocr_main_chestpack", nil]}

Thank you! 👍

the macro actually expands to bocr_main_chestpack. Easiest way to check if a player has a chestpack is to run

if (isNil {_unit getVariable ["bocr_main_chestpack", nil]}) then {
systemChat "Unit does not have a backpack on their chest";
};

`_unit getVariable "bocr_chestpack"` (98% certainty), as defined on line 52 in the `/addons/main/functions/fnc_addChestpack.sqf` file, showing what the var contains.
