Yeah, either place an empty vehicle, or a full one, name it something (I used carname) and put in it's init field :
deletevehicle driver this
And if it has a gunner :
deletevehicle gunner this
To put new people in it, place them in the editor, in the drivers init field :
this moveindriver carname
And if it has a gunner :
this moveingunner carname
And that should be it
BTW, the init field only shows up in advanced mode (Which I reccomend you use all the time anyway
)
Sorry if you know half this stuff, but you didn't say how much you knew about ofp
Gd luck
