detecting whether a vehicle is on burning

[yourry 14]

Hello,

I wanted to know if you have a method to detect if a vehicle is on fire.
When I use the command on "isBurning" a burning vehicle it returns FALSE me.
For example :

 

heli setDamage 1;
sleep 5;
hint format ["isBurning heli: %1", isBurning heli];

//-> return FALSE :(

Thank you
