Smoke over some objectives...

for thouse who was trying to make a smoke on some objects, for exemple on ammo box after supply drop, that how i managed it, kill like half day on different variation, this one works perfectly, you can change color by changing SmokeShell on SmokeShellGreen or others, test2 is Triger, wich will exec you sgf on activation... 200 is radius where you can look for that object and 100 is time for smoke

list1 = position test2 nearObjects ["RUSpecialWeaponsBox",200];
nObject1 = list1 select 0; 
hint format ["%1", getPosASL nObject1];
i=1;
while {i=i+1;i<100} do 
{
  Smoke1="Smokeshell" createVehicle position nObject1;
  sleep 1
}

what do I put in the trigger activiation text to kick this into action?
