(A:Eng1 N1 rpm, number) 0 > if{ (>K:SMOKE_ON) } els{ (>K:SMOKE_OFF) } Also, where can I find a resource for the vector graphics commands available?Thanks, Patrick

Or, perhaps ".. els{ 0 (>K:Smoke_on)" to turn it off. Ron

Hi Ron!You don't need to write a 1 or 0 in front of those (>K:...) vars! As Smoke_OFF already tells FS to turn smoke off, you don't need the 0 or 1. You would need it if you do it via (>K:Smoke_SET)!I don't know whats wrong about the code. It works fine for me(FS2002).Maybe the problem is somewhere else(maybe the Engine Variable isn't used in the plane. There are that much engine parameters that you often choose the wrong one. Try to use Airspeed as a variable, then you can see if the code works or not!)Regards,Harry

You would need it if you do it via>(>K:Smoke_SET)! I wasn't sure. In a RELOAD_PANELS file I have there are 0 and 1 ahead of the variables. Maybe because I had added "0 (>L:TestInit,bool)" to reset a counter I had in my main file and put "1" ahead of the K: event. >I don't know whats wrong about the code.

Thanks guys.I have a heli I'm using it with, and I'm not sure, but it seems to be working after all, lol.If not, I'll try different variables as you suggest.Patrick
