Thanks remcen, but I still don't get it. Here's an entry in the config for class Man:
   class Man: Land
...
armor=3
...so the Man class also has armor defined in just the same way as a Tank or a Helicopter, but the Man class uses the HitMan sounds.
Also, look at the building entry:
class Building: Static
...
armor=150
Again, armor values are defined in the same way, but buildings use the sounds defined for the hitBuilding "event".
So...how does the OFP engine "know" how to use hitArmor, hitMan, hitBuilding, hitGround etc? If it plays the sounds according to whether an entity is a man, building, vehicle or ground, where is this link defined?
I just don't see any entry in the config that links the classes to the event. :'(
Thanks again,
CH
