I may be way off base here , but have you tried using a number in the 74..CB range? (RV IDs, not train IDs)

AFAIA, the callback uses the NFO ids, not the global vehicle IDs. At least, that's the way stevenh had me code the hiroshima trams test grf (which is where Sir Bob has copied the code from).

No, it won't. Specifying a sound effect that doesn't exist causes no sound to be played.

Ok. I'm sure I've managed to code sound effect callbacks that crash TTDP before, although that may have been with an earlier build.

Okay, I've got rid of the sound effect callback but it hasn't helped at all.
My articulated trams still don't show up but non-articulated trams do.

If anyone can find something else wrong with the code please say so.

Thanks again,
Sir Bob

EDIT: Do I need to change anything to do with what DaleStan said before?

Hmm. Not showing at all?

... your action 3 is for a different ID from your action 0.

You probably also want to change the callback return from 50 to this vehicle's ID.

I checked with him a few week ago. Apparantly they do just about work, but are very buggy.

I've changed everything you said (I think) but it is still causing problems. I've uploaded my latest .NFO file (The problem is with the last tram)
Another weird thing was found as well, if you have the German Tram Set activated you get the tram, but only the first vehicle.
On another note my Action 4's don't work.

Once again, any help is apprecciated

The meaning of this byte depends on the GRF version of the .grf file as set in action 8.

I advise you re-read this section a couple times; you obviously missed something important in there.

And you're setting the wrong bit in prop 17.

And the last action 0 is still setting properties for a different ID than the action 3 that precedes it...
(I think I said action 2 before, I meant action 0.)

What line is the property 17 on?

The line (or lines) that contain the only action that can set properties.

This should be obvious, and there shouldn't be more than a few such lines.
