If you guys can think of anything to add to this, let me know. Schm0 19:58, 30 October 2007 (EDT)
- I would suggest changing the region numbers to 101-107 etc, as they're unlikely to be already used, and most pregen maps (packs and non-packs) are unlikely to ever use that range either. --Edward 23:01, 3 January 2008 (EST)
Oh yeah, and I can't get the last graphic to show, even though it exists. Schm0 20:17, 30 October 2007 (EDT)
It took me *way* too long to figure out, but I know why the last picture isnt showing. It has "ad" in the URL, and you are using AdBlock.
- Thank you, anonymous. :)
From my own little experiments, it looks like the /wait commands aren't needed. There may be a difference in OS here, but under Windows XP Home SP2, I can create a .bat file with
dwarfort.exe -gen 1
dwarfort.exe -gen 2
right after the other. When one creation ends, the window closes and the next begins. The two [RANDOM]s aren't required, either. If the .bat is in the same folder as your executable, you don't have to go through the whole "C:\df\whatever" tree, either. Mephisto 16:08, 9 November 2007 (EST)
- Well, like I said, it's for you to use or modify if necessary. I know that it will be compatible on all copies of XP and beyond... I don't care to bother and check what version of XP I have, but the batch program will not function correctly unless I use the /wait commands. Obviously you wouldn't need to include the directory of the files, unless you ran it from the desktop. Some good observations, nonetheless. Schm0 22:15, 5 December 2007 (EST)
- I just tried this without the "start /wait" part, and it didn't work for me (Win XP SP1) - it generates only one map, then stops. Leave the code as it is.--Siliziumleben 21:32, 2 January 2008 (EST)
- Like it more this way. If you'll have any problems with 'wait's, just add it.--Dorten 01:42, 11 January 2008 (EST)
i dont get seeds.. sure theyre not random... but what do they do? a list of different seeds and what they create? Twiggie 10:16, 5 December 2007 (EST)

On random seeds... It is very difficult to make a number that is truly random on a computer. Instead of doing something like hooking up a Geiger counter and a source[1] to generate a pseudo random number, you pick a starting point - a seed. You can run this number through a function[2] and get another number. This new number is returned and used in the next iteration. This is a pseudo random number sequence[3]. One of the things that is useful about a pseudo random number sequence is that it is deterministic - if you start with the same seed, you will get the same random numbers. Thus, when you use the seed someone has provided, you will get the same world generated. --Shagie 17:26, 29 February 2008 (EST)
With v0.27.176.38c, in world generation you can now select the size of the world. For example - a pocket world (above) - thats it, thats the whole thing. --Shagie 17:26, 29 February 2008 (EST)
