If you save our map and then press preview, it should
be updatet with all addons being used, except those
which will be added by through scripts or may be inside
ammo crates.
You have two options now:
a) edit the mission.sqm file with your notepad and enter
the bis_weaponpack manually there.
You will find the addons and addons Auto list near the
top of the mission.sqm.
b) place a soldier which already carries the weapon on
the map (if there's one available from the units box).
Most of the addons comming with such a sample unit.
In your case it's easy, as it's the bis_weaponpack, which
you're missing. BIS addons always come with sample units.
All you need to do is: place a unit on the map, which carries
one of the weapons listed below:
New weapons
* Hunting Rifle (HuntingRifle, HuntingRifleMag): civilian hunting rifle with optics. Very strong but a bit slow.
* G-17 - silenced version: This is the silenced version of standard G-17 (but with less range).
* Revolver (Revolver, RevolverMag): very powerful yet very slow hand gun.
* M-10 : submachinegun used as handgun. Not the most accurate weapon but has a high rate of fire and clips that hold 30 bullets.
Now you just need to save your map and then preview it -->
addons list in mission.sqm should be updated from now.
hope this helps
