1- Look at your mission.pbo/server_traders.sqf
You will found a list with all your server traders and their TIDS.
// Bandit Trader
menu_RUS_Soldier2 = [
[["Ammunition",577],["Clothing",575],["Helicopter Armed",512],["Military Armed",569],["Trucks Armed",534],["Weapons",627]],
[],
"hostile"
];
( for exemple Helicopter Armed TIDS is 512 ... Keep this number
2- Go to your data base and open your trader_tiems table...
click on insert and complete the box like this for adding UH1Y with ammo at each restart:
ID : let it blank
Class Name : UH1Y_DZ
Type : 2
Group : Helicopter Armed
Afile : trade_any_vehicle
Execute
3- Open your trader_data table and click on insert.
Complete the box like this:
ID: leave it blank
Item : ["UH1Y_DZ",2]
Qty : 30
Buy : [6,"ItemBriefcase100oz",1]
Sell : [1,"ItemBriefcase100oz",1]
order : 0
TID : 512
afile : trade_any_vehicle
Execute.
Now close your data base and restart your server.
The bandit trader now sell a UH1Y with full ammo at restart.
This is how to add any vehicle to any trader. You can do the same path to add other item to the right trader but in this case you will need to modify some stuff like the afile, the tid, etc...
UH1Y_DZE = vehicle without ammo at restart
UH1Y_DZ = vehicle with ammo at restart.
