I didn't like how the cities grew over my roads and industries and would like to decide where they build new buildings. With later versions of Simutrans it is possible. I did this:
I went to the pak directory and inside it, made a backup copy of
cityrules.tab, just in case I want to get the default behavior back.
Then, I edited the file (pak64, r1972):
- Changed renovation_percentage=12 with renovation_percentage=8, so that cities spread more
- Put a comment character (#) at the beginning of all lines starting with house_ or road_
I inserted these lines before the first
house_ line I have commented out (notice the spaces and dots):
house_1 = ..... .sSS. .snS. .shS. .....
house_1.chance = -2
house_2 = ..... .SSs. .Sns. .Shs. .....
house_2.chance = -2
house_3 = ..... SsS.. hsn.. SsS.. .....
house_3.chance = -2
I saved the file and run simutrans. With these changes, you get:
- Cities will only build new buildings on straight streets with previous buildings, and up to the next corner
- Cities can also build new buildings in front of an existing one
- When founding a new city, you have to make the first street with the public service player and perhaps, put a first building on it
With this, you decide where the city will expand. If you have a straight road and don't want the city to invade it, just make a "fake cross" like the one in the picture. The city will not trespass.
