Just a guess: gpPlayer() returns null if you are hosting it on a dedicated server and gpPlayer().Place() returns null if the player is not within an vehicle.
Code:
private void DoDamage()
{ // Script that triggered an accidental damage to the player plane
// Author: FG28_Kodiak Modified by: Salmo
// Ref: http://forum.1cpublishing.eu/showthread.php?t=22184
if(GamePlay.gpPlayer() != null && GamePlay.gpPlayer().Place() != null && GamePlay.gpPlayer().Place() is AiAircraft)
{
PlayerPlane = (AiAircraft)GamePlay.gpPlayer().Place();
...
}
}

Thanks Banks, I thought the same, so I've played with removing the Dodamage() call etc but it did not fix the error. So while your code suggestion is more elegant (& I've implimented it), it doesnt fix the NullReferenceException error

Hi Salmo,
I've been seeing this error through the dedi box since the game was released (scripts or not). There's still a huge disconnect between running missions through the in-game GUI and running them through the -server. Nice stuff you've done with scripting btw!

Cool. Simple modification, to add a random delay before failure:
Code:
public override void OnAircraftTookOff(int missionNumber, string shortName, AiAircraft aircraft)
{
if (m_random.Next(1, 200 + 1) != 67) // 0.5% chance of takeoff failure
{
Timeout(m_random.Next(1, 60), ()=> DoDamage(aircraft));
}
}
