You're welcome but the ones to really thank are those amazing developers who keep coming up with all these neat features.

Hi!
Maybe I should post it into TTDPatch problem section, but ohh well.....
I have little problem.... When I type into sign cht: landgen 2 40 2 It generate nice map (flat, with water etc). But if I choose 'New Game' game asks if I wanna start new game. I answer yes and after that game just freeze. No crash log and in task manger ttd is not responding! I'm using nightly 1430!
And what I should post here? Save game, cfg?

Ok thanks! Dealing with it when I'm back from work!

Is it possible to specify the number of towns when creating a random map? I never seem to get just the right amount (about 20 +/-2)!

ISA · Post by **ISA** » 23 Apr 2007 14:28

He!
I have one problem again!
I'm using nightly 1518 and if I wanna create map (like Cht: landgen 10 35 10 - its map with some water and hills) or some other map/cht the game shows me that cheat was successful, but if I start new game the map haven't change! There is lots of flat land with few small lakes!
My experimentalfeatures is set to 48
Some help would be useful

The last changes made by Urzupator to the terrain gen completely disable (well, to be correct "plainly ignore the existence of") the LandGen cheat.

I've started working on cleaning up and fixing the current incarnation of the code as well as reenabling the cheat, however real life has stepped in and it will take a while longer to finish.

Well.

I don't know how the cheat works, so I couldn't make any provisions for it in the latest refresh of the code (there was a massive change in the structure of the code)

I can provide a function which will make it work, but I need to know what actually was called before.

Looking at the previous revision of cwrap.c would help - specifically http://svn.ttdpatch.net/trac/browser/tr ... c?rev=1328 lines 209 - 213

Neat.

I'll fix it asap - altho - this things are not in my version - they were added when I couldn't commit or update my copy of the repository.

BTW - how to extend the cheat to say - 5 parameters?

minime · Post by **minime** » 24 Apr 2007 10:07

Well, at the moment, the cheat packs the parameters into one DWORD.

Initially the value of this variable is 0xFFFFFFFF (-1), which is also used to represent "cheat off". When the cheat is used, the parameters are packed into the low 3 bytes of this variable, with the high byte being set to zero.

In my rewrite, I have extended the cheat by using bits 24-30 as an extra parameter, used to specify the terrain generation method (basically to enable the user to pick which one of your "themes" to use). Bit 31 is still used to determine the "cheat on/off" state.

If you need more than that, it will be necessary to enlarge the variable used to store the parameters. Unfortunately I don't know enough about patch coding to be able to reliably guide you there. All I know is that the cheat values are stored by code in signcht.asm (label landgencheat).

----

Hmm, after looking at the code, the variable landgen_forceparam is defined only in signght.asm, so extending that should be easy.

The best way to get more space is probably to change the variable's declaration to "svard landgen_forceparam, 2", which will give you a two dwords, both initialized to -1. The extern in the C code will have to be changed to match, of course: "extern int32_t landgen_forceparam[2] asm("landgen_forceparam")". Alternatively, you could add a second variable of a smaller width (svar[bw]), but that would require two variable names, and is probably not worth the hassle.

Can you give us some idea of how to use it? There's no documentation?

Tried looking here Dave?

Post by **Dave** » 16 May 2007 19:37

Hardly a lot of information? Is there no specific information?

Mickeye · Post by **Mickeye** » 10 Jun 2007 08:12

I was trying Cht: LandGen in few latest nighlies and it doesn't wok in same way as LandGen cheat in older nightlies (before r1456). Is there some sort of info how LandGen cheat works in nightlies after r1558? If no, could be someone so kind and write new info? Thanks in advance.
