Hi everyone, I'm announcing that the wildfire nasal code in fgdata has been converted to an addon.
2020.4 and on will require the addon to get wildfire as the code has been removed from the base. If you want to use it on any other FlightGear version, just rename fgdata/Nasal/wilfire.nas to wildfire.org and use the new addon interface.
There are a couple upgrades and hopefully more to come. Fire propagation is now wind driven including speed of growth and direction. Also elevation change should have some effect but needs more work. I also added a random radius and time fire ignition section to the GUI. You can set a random timer to ignite a fire at a random radius and time. There is an option have it report the lat, lon, bearing and range upon ignition.
It's great fun to sit on the tarmac waiting for a spot fire to ignite and race to get the AirCrane or Catalina loaded with water and put the fire out before it expands to the point of no return.
For an extra challenge use the Cargo Towing addon and add a water tank to fill from, this requires the AirCrane. CL35 is a perfect place for a base of operations. Located in the back country of So California in the chaparral covered mountain. Lake Henshaw is close by and large enough to use as a water source for both the Catalina and the AirCrane fast loading capabilities. The AirCrane can load water from virtually any water source using the snorkel, including tanks, ponds and even streams. Have fun!
Special thanks to Anders for the original code for wildfire.
