How does level gen work?

[wobbly]

Thanks will give that a whirl. Also starting to think what I want might be more like:

y_size = z_info->dungeon_hgt * (size_percent - 20 + p->depth / 4 + randint0(10)) / 100;
x_size = z_info->dungeon_wid * (size_percent - 20 + p->depth / 4 + randint0(10)) / 100;

That gives a range of 31%-82% on dlvl 1, the old sizes at dlvl 60, & around 20% bigger at dlvl 98 (the questor levels are set to 100%). The range is probably too big at dlvl 1 there so maybe I still have to split it off into another profile to get it right but I'll try this & see what happens

y_size = z_info->dungeon_hgt * (size_percent - 20 + p->depth / 4 + randint0(10)) / 100;
x_size = z_info->dungeon_wid * (size_percent - 20 + p->depth / 4 + randint0(10)) / 100;

Ok dived through 20 levels & it pretty consistantly gave me around the max. size that'll fit on the screen. Sometimes smaller, sometimes a little bigger. Didn't manage to split it off into another profile, I got this on trying to compile:

DUN("small', small)
             ^
generate.c:65:25: nite: in definition of macro 'DUN'
  #define DUN(a, b) {a, b##_gen},
                        ^
make: *** [generate.o] Error 1

so I'm obviously doing something wrong there.

In the labyrinth generation, there is a line of code that scales the number of monsters by the level size:

    /* Scale number of monsters items by labyrinth size */
    k = (3 * k * (h * w)) / (z_info->dungeon_hgt * z_info->dungeon_wid);

It seems like this line ensures that a labyrinth has 3x the "monster density" of a normal level (correctly scaled with its area as t4nk and wobbly observed).

Maybe it can simply be copied also in the other profiles, without the 3?

Not unmodified (h and w are undefined in modified gen) but I'll see if I can work out the equivalent.

[wobbly]

Ok it's this bit

/* General amount of rubble, traps and monsters */
    k = MAX(MIN(c->depth / 3, 10), 2);

/* Pick a base number of monsters */
    i = z_info->level_monster_min + randint1(8) + k;

I'll work something out there

Looks like you have different kinds of quotes there? (double and single)

[Pete Mack]

Yep. You want double quotes for a string (array of char) for that. Single quote for a single character.

DUN("small', small)
             ^
generate.c:65:25: nite: in definition of macro 'DUN'
  #define DUN(a, b) {a, b##_gen},
                        ^
make: *** [generate.o] Error 1

Ouch. You *need* a better editor. Anything with a decent syntax highlighting will color this line in a way that makes the wrong quote obvious. You risk wasting a lot of time unnecessarily otherwise.

[wobbly]

Anything you'd recomend? Free and for windows?

Got it to compile. There's a bit that needs to go in generate.h

[fph]

I'm not that expert on the Windows side of things, unfortunately, so probably you'd get better results by Googling around (e.g. https://www.slant.co/topics/795/~bes...r-c-on-windows)
I am now using Sublime Edit, which is sort-of free (has very occasional nag screens in the free version) and is available on Windows, too. I've heard good things about Notepad++, and Microsoft now has a free version of Visual Studio.

Thanks will look round. Well I can change stuff and get it to compile so I can play here. You can enforce it to the early levels in generate.c just under where it picks the town. I might enforce a moria level and questor tag the balrog to see how that goes. There's stuff to play with for a bit.

Notepad++ is my go-to text editor. It has syntax highlighting, regular expression find and replace, and some pretty nice text manipulation tools in the TextFX plugin. It also has a compare plugin which is helpful.

Visual Studio is the only compiler I can use on my work computer, but be warned that it doesn't support a lot of newer (C99) C programming things that make compiling newer Vanilla or anything based on it a major problem. Notably, VS does not allow variable length arrays, i.e.
int size = 80;
char text[size];

You have to make a constant expression for it to work, i.e.
#define size 80
char text[size];
#undef size

I'll look at notepad++
I've been compiling with mingw. Seems to work for me

Notepad++ is what I use in general, but I bite the bullet and use VS to work on composband code
