With "Enviromental" Types I mean all objects listed in FMB under "Enviroment" (?not sure if thats is the right designation in the english installation, I have the german one installed). For excample this object:
Static274 Stationary.Bf-109E-1 de 280631.88 212409.64 3665.00
or this
Static278 Stationary.Renault_UE_Track_CargoSet2 gb 245508.16 233959.69 -120.00
Is not recognized with OnActorDestroyed of course, because it is no actor. Artillery-Objects in FMB as:
Static258 Artillery.Bofors_StandAlone gb 88914.33 195537.75 75.00 /timeout 0/radius_hide 0
are Actors and are therefore recognized - that was what I tried to say.
