trigger activated smoke grenade

[ual002]

How do i make a trigger activated smoke grenade for when I approach an LZ in my blackhawk from like 500 meters to pour out a specific color of smoke from a smoke grenade fo a specified period of time?  Red=hotzone green=clear etc.  Like 2 mins or so.

Ive found some trigger activated AP mine posts but I need a large radius trigger and a specified ammount of smoke.  Anyone point me in the right direction.  Editing Essentials: A Beginners Guide by Mack also helps but where the coding for it is, there are mixed in characters which look like this ^%#E(*&^ and i cant quite read whats going on.  I belive that was a mistake.

Also, anyone know where in the editor the brick and mortar building w/ red cross on it is.  I know about the tent, not what i need.  I have the editor addon, but im not seeing it.

what if i just wanted a smoke grenade on the ground to start smoking once i got close.  Or would that be harder.

_smoker = "SmokeShellRed" createVehicle (getpos trigger)

then

_smoker setdammage 1

not sure of the new syntax...you'd have to look it up to be sure

If it's for MP...dunno..maybe createVehicleLocal

oh yes, sweet, I wa wondering how can I make a handgrenade to detonate in ArmA, this way works very well. You didn't need to set damage to grenades in OFP, they would explode as soon as they where camcreated.
I just noticed, there is no flares in ArmA?
I have all this traps in the field, it would be nice to have some flares too.
