So after playing in a multiplayer game with a trainset that has running sounds, i have grown even more disappointed with the GRF's i use that run in pure silence, so my question is:

is it possible to have a GRF to add running sounds to others? (both road and trainsets)


Since i dont use this site too often i apologize if this is in the wrong spot, if there is a more fitting location i will repost there instead.

Funny you should ask that, since I've been trying to work on a sound add-on for the NARS 2cc add-on. As far as I can deduce, the answer is no, in NML. I'll come back with technical details later for those who are interested, showing the experiment I did.

Yes but it's not trivial.

EDIT: but if you plan on changing callbacks, you need to re-define *all* callbacks of that vehicle. You cannot simply add one.

It seems much easier to get the source for the set you want to add sound to and hack that.

Edit: sorry for the misinformation, see Michael Blunk's response below.

This is not possible. You can´t add/change custom sounds (action11 / CB33) by "overriding" destination newgrf properties by another newgrf. You´ll have to modify the source of the newgrf in question.

Isn't it possible in case of road vehicle newgrfs? I found strange behaviour/bug maybe: I defined custom sounds for tram newgrf and truck/buses newgrf, and other one inherited the first one sounds - truck were ringing etc.

but if there are no sounds there at all, does that really still count as "overriding"?

You really can add/override sounds. You just need to replace all callbacks, as I found out.
