what I mean by object (as defined by zmodeler 1 I think?), is collections of meshes in the 3ds file..
for example I think of the front left wheel dummy as an object within the 3ds file...
What I want to achieve for now, is to be able to (with irrlicht) to
a) load a single 3ds file and
b) then afterwards select for example the front left wheel dummy object
c) and then hide it,
d) then I want to load another 3ds file that contains a wheel, lets call it testwheel.3ds
e) and then use the coordinates of the wheel dummy to place the wheel from testwheel.3ds
f) and then use the local axis of testwheel.3ds to "spin" the wheel while moving the car
spinning and rotating stuff like wheels, steering wheel, running gear parts etc, could be done simple by rotating them along their own local axis
So either I need to find out how to do this in irrlicht or else I will need to place all parts of a car in seperate 3ds files and then use a setup file instead of dummy objects to assemble the various meshes from the various 3ds files in to a car
the setup file would then need to contains something like this:
body, x, y, z position
steering wheel, x, y, z position
front left wheel, x, y, z position
front right wheel, x, y, z position
rear left wheel, x, y, z position
rear right wheel, x, y, z position
front left headlight, x, y, z position
front right headlight, x, y, z position
rear left taillight, x, y, z position
rear right taillight, x, y, z position
engineblock, x, y, z position
manifold, x, y, z position
enginefan, x, y, z position
etc etc
IF Irrlicht supports multiple objects within a single 3ds file, then most stuff could be handling using dummys within the cars 3ds file...
Anything that can be replaced or moved in some way or have some other function like lights would need dummy objects
The other option to have a bunch of 3ds files would also work and might make it easier to be able to replace body parts like doors etc... I was thinking that it could be kind of cool if it was possible to for example replace the left and right rear fenders with other types... like one set of fenders could have "wings" and another set could have no wings... stuff like that (like in Gearhead Garage )
