thanks for your answers, but unfortunately did not help...
1. "laserguidedbomb" camcreate getpos chopper1
a lgb appearing and falling, whet hit the ground exploding...
it looks like more like bombing...
2. "Explosion" camCreate getpos (your chppers name)
this explosion looks good, but cause no harm to the chopper and has no sound...
After searching and experimenting I set up this script, and it works now:
MySatchel = "pipebomb" camCreate [(getpos chopper select 0) + 10, (getpos chopper select 1), (getpos chopper select 2)]
MyBlast = "SHELL73" camCreate getPos MySatchel
~0.2
deleteVehicle MySatchel
deleteVehicle MyBlast
exit
It means I had to camcreate a shell73 to explode the satchel...
and after delete these...
thanks anyway
bye
