There are two places you can set this information (if I'm not mistaken).
In item_db.conf
in the argument:
Subtype: "W_1HSWORD"
And also in the file itemInfo.lub (in lua files)
in the argument:
ClassNum = 4
If you want to check information on the types of weapons
You can look at the files: weapontable.lub (at your date)
and also in item_db.txt (emulator / doc)
got it. in my case, i had to change View to the correct weapon class since my database is old and doesn't support subtype. the client info was useful as well, i may need that in the future. thanks man.
