TGP, its advantages and one good thing to know about
Since TGP was merged into the trunk, OTTD-maps started to look really good. “Perlin Noise” is the name behind the function which generates this real-world-like maps we all like. The good news for you: #openttdcoop uses TGP since we switched to Nightly r5993.
The bad news for #openttdcoop: it was quite hard to understand why TGP didn’t accept our settings. Usually, for a dedicated server, you edit your openttd.cfg. You may select a TGP-seed in the variable “generation_seed =“. The thing about Linux and OTTD-Dedicated: this seed will not be used by the server! Instead, it always takes the same seed which represents 2^32. For dedicated servers on other system it should work though.
After some three hours of nuisance and despairness we gladly got help by Rubidium. He also gave us a clou for a workaround: just start the server and make a newgame via console (command: newgame).
