well the event handler is pretty easy,
this AddEventHandler ["event", "actiontotake"]
so it works like ths
this AddEventHandler ["hit", "hint {I'm hit}"]
the other events are
Killed
Hit
Dammaged
GetIn
GetOut
Init
Engine
Gear
Fuel
Fired
IncomingMissile
and you can use {} instead of " " for strings now, setvelocity is weird, I can't get things to move where I want yet
vehiclename setVelocity [1000,10,10]
[edit]
it looks like Chomps has figured out setvelocity
here.
