[patch] More Map Settings v2 (r14439)

[Alberth]

So... who's in the mood for writing YAMAGEN (Yet Another MAp GENerator)?

For the benefit of scenario's and height maps, it may be better to implement (exact or random) placement of everything by reading generator commands or so from a file.
The generator problem can then be shifted to an external program.

New version!

- it allow player to set count of towns instead of total population
- the algorithm was code-wise vastly simplified

You can now set the count of towns to any number between 1 and 5000

[Terkhen]

I'm going to try it immediately!

I LOVE YOU

It works perfectly, I may never download another version of openttd, it is now complete.

Thank you so much!!!

[PhilSophus]

AFAIK it doesn't and it's a shame. We really should talk the devs into reworking the damn town placement, because at the moment and ever since, it's totally random.

Well.. yes, it is purely random. And there is absolutely no reason whatsoever that it would have to change. Sorry. But that's how it is.

And by purely random you obviously mean distributed by a Poisson point process, i.e. uniformly distributed. Any other random distribution is also purely random (if you accept pseudo-randoms generated by a linear congruential generator to be random at all for a moment. Is there any effort to make the Mersenne Twister network-safe?).

Funny enough, I just read that the uniform distribution is perceived as slightly clustered by most people including me (clustering illusion).

You confuse me. Do you alway rename the patch or is this NOT a new version of original MMS, but something additional?

[CommanderZ]

It is a new version, but it lacks the water level feature for now, so I'm calling it differently.

[Octopuss]

any news?

[CommanderZ]

I'm very busy nowadays. Busier than ever, sorry, I don't have time to even play games, not speaking of developing them

[Octopuss]

Soo, when you have time, what are the plans for future versions? Or do you consider the patch complete?

[Terkhen]

I'm using the v1 patch found at the first post. When using "Very high" water level at 2048 x 2048 maps, the map is created with no water at all. I have been tinkering with the HeightMapAdjustWaterLevel function at tgp.cpp and I found two variables (water_tiles and desired_water_tiles) that needed to be bigger. Here is the patch with my small changes. I hope it helps

[CommanderZ]

Oh, thanks

I still believe I will be able to finish this when my exam term is over

I have been trying some stuff in the map generator lately. More precisely, trying to generate maps that looks like the western part of norway, with fjords, and an increase in height going from west to east. When doing that, I realized that the random distribution of towns is far from realistic on mountainous maps, many of my cities appeared in the eastern highland, above snow level.

I like Roujin's idea of having a dropdown:

Well, it could be a dropdown like the other dropdowns we already have for map generation.

Town placement
* Random
* Equal distribution
* Clusters

And maybe someone can think of additional options. Maybe something along the lines of "towns are only in the center of the map; the outer ring is reserved for industry".

So... who's in the mood for writing YAMAGEN (Yet Another MAp GENerator)?

A "realistic" setting could be made in the following way:

- First, we figure out (or guess) how the world distribution of cities is (how many are placed close to the sea, how many above a certain height, how much less likely is it to find a city above snow level etc.)
- Then we distribute the cities accordingly. Still random, so that clusters can appear. (If there is a need for determining the degree of clustering, that may also be a parameter, but it probably complicates things)
- Other possible parameters to review thoroughly may be the size distribution of cities and the correlation between size and position.

This new generator may of course have very different values for the given No. of towns than the original

It's about finishing, isn't it? Passed all of the exams I hope?

Still one left. I gonna pass it tomorow. I hope.

Ok so I hope everything went the best way and we can be expecting updated version of this awesome piece of artwork
Hell, if it gets released I will start compiling my own builds again as this is absolute base of everything!
