Very simply - the scripting commands AssignItem an unAssignItem do not work for weapon attachments.
The commands work for NVGs for example but do not move weapon items to/from the inventory. In some cases they will delete the weapon from inventory but not attach to gun. The same applies whether the slot is empty or full.
Create a infantry unit
add to the init line
diveSquad = group diver1; this moveInCargo boat; this addbackpack "B_AssaultPack_blk"; removeAllWeapons this; pack = unitBackpack this; this addMagazines ["30Rnd_65x39_case_mag",7]; this addMagazines ["16Rnd_9x21_Mag",3]; this addWeapon "arifle_TRG20_F"; this addPrimaryWeaponItem "optic_Hamr"; this addPrimaryWeaponItem "acc_flashlight"; this addPrimaryWeaponItem "muzzle_snds_H"; this addWeapon "hgun_P07_snds_F"; unitBackpack this addItemCargo ["NVGoggles",1]; unitBackpack this addItemCargo ["acc_pointer_IR",1];
Then create a trigger with
time > 20
as the condition, and on act
player assignItem "NVGoggles"; player assignItem "acc_pointer_IR";
Only the NVGs will equip.
