Tunnels
Png and dat patterns
Unlike ways and bridges, tunnels require few images. They are always composed of backimage (images displayed behind passing vehicles) and frontimage (images displayed before the vehicles). Here is the pattern:
obj=tunnel
waytype=
name=
cost=
maintenance=
topspeed=
way=
copyright=
intro_year=1800
intro_month=1
retire_year=2999
retire_month=1
icon⇒ source.1.2
cursor=source.1.3
frontimage[N]=source.0.0
backimage[N]=source.1.0
frontimage[W]=source.0.1
backimage[W]=source.1.1
frontimage[S]=source.0.2
frontimage[E]=source.0.3
Tunnels can have snowy images. To define them, a parameter must be added to the name of each image, equal to 0 for normal (summer) view and 1 for snowy (winter) view. Here is an example:
backimage[N]=source.1.0
#becomes …
#normal view
backimage[N][0]=source.1.0
#snowy view
backimage[N][1]=sourcewinter.1.0
