Myself I'd go with types because it looks cleaner, and wouldn't expect much performance impact between indexes and types.

Type car
Field IP$
Field Name$
Field r,g,b
Field NextWaypoint
Field x,y,z
..

thanks wayne..

if i use types...

you use,

for car.car = each car
moveentity car\entity,x,y,z
next

but how you pointentity the camera to x car? the player car for example, or other car you want, how you make that?

for car.car = each car
if car\id = X then pointentity camera,car\entity ???
next

so, each time i want choose a specific car for something, i nned mame that loop?

(soory my english)

Create different instances of the same type like;

car1.tCar = new tCar
car2.tCar = new tCar

then just

pointentity camera, car1\entity

As well as the ID per car, you could also create an array of types ...

Type CarT
  field Entity
  field Blah
End type

dim CAR.CarT( 99 )

for l = 0 to 99
  CAR(l) = new CartT
  CAR(l)\Entity = Copyentity( CAR_MESH )
  CAR(l)\Blah = ???
next

Then to point to car 4 do this:

pointentity CAMERA, CAR(4)\Entity

I've still not gotten round to using an array of types, but the potential of them looks pretty sweet.
