Also, i have a question : is it possible for a station tile to automatically detect a road nearby ?
Somewhat: you can detect the tile type, e.g. that there is a road - but not which layout or configurationhttp://newgrf-specs.tt-wiki.net/wiki/Va ... s_.2867.29http://newgrf-specs.tt-wiki.net/wiki/Va ... s_.2860.29
Meh, I don't need configuration, just are there any roads or not
(Hmm, probably also empty tiles if no road detected ?)
Also, I would need to know how does it affect the way the station drawed. Any lights on this ? (as theres no example and i don't know any GRF which also use this)
I'm hazarding a guess, but it may be that your graphics are defined for the back part of the station rather than the front part.
The drawing order is ground tile - back station part - vehicle - front station part. Thus the front station part is drawn overtop everything, and that's what you need for this type of station.
No, Foobar - if you mean the vehicle, maybe thats what we need, but for catenary, due to my "roof" is drawn in the same height to your camouflage catenary, it'll always draw a catenary on top of my roof, only the RET signs will appear over. You could test it yourself.
