Customization of gamedata files

[tangar]

It would be great to add 'simple' condition's system to gamedata customization. It would be give wide possibilities, eg to make different races to react differently at stuff.

It could be called: flagcheck

Example of impementation: in PWMA we have corpses of monster. Why not to give possibility to eat them (hello, Nethack!). But different races should have different effects on eating corpses. We can't let elf to eat orc's corpses without consequences So, eg:

name:corpse (orcish)
graphics:%:w
type:corpse
properties:0:100:0
combat:0:1d1:0:0:0
[B]flagcheck[/B]:race: ELF | HIGH-ELF # works at elves
effect:SET_NOURISH # this would happen to all elves
dice:$B
expr:B:FOOD_FAINT:- 1
random: # this is random event which could happen in addition
effect:TIMED_INC:CONFUSED
dice:20d40
effect:DRAIN_STAT:WIS
dice:1
[B]flagcheck[/B]:race: HALF-ELF # half-elf is better in eating orcs ^^
effect:SET_NOURISH
dice: 1000 # as we don't have hunger as timed status effect yet, lets just take weak status ;)
[B]flagcheck[/B]:race:except: ELF | HIGH-ELF | HALF-ELF  # next effects would work at everyone else.. donno how to implement better ('except'?)
effect:NOURISH
dice:1000
desc:Whatever happened with this one, it wasn't pretty.

It would bring customization to the new lvl

It seems it works this way (thanks to Powerwyrm for help):

spell:Detect Monsters:1:1:23:4
effect:DETECT_VISIBLE_MONSTERS
dice:11d2

dice is radius. For x and for y; so:

11 tiles horizontally
2 tiles vertically

so 10d10 would be LOS

/rfe
maybe it should be not 'd', but 'r' (radius).. Like 11r3

cause right now it's very messy with RPG dice notation

[tangar]

/bug (?)

1) it seems 'dice:n+4d2' doesn't work (and dice:4d2+10 would crush the game)

I've tried several tests:

dice:10+4d2
dice:50+4d2
etc

eg

spell:Detect Monsters:1:1:23:4
effect:DETECT_VISIBLE_MONSTERS
dice:10+4d2
desc:Detects all non-invisible monsters in the immediate area,
desc:for one turn only

it works as 4d2, not as 10+4d2

2) when I make spell:

dice:11d2 - it works at distance ~4, not 11-22

dice:8d2 - works as... 8. not 8-16
8d3 also works as 8

That's worth thinking about. What do others think?

I think it would be a mistake to have both systems in place. Having it in object.txt is quite elegant. But it depends who you're optimising for - existing tileset maintainers or new tileset producers. If the latter, you want tilesets as modular as you can get them; if the former, you want everything in one place.

[Nick]

What about to give a possibility to assign an object to tileset 'quick&dirty' way (actually it nice and clean.. ), right in gamedata file? eg:



where:
tile:[number of tileset]:[x]:[y] , so in eg above 'tile:3' is Gervais tileset; 'tile: 4' - Nomad.

and make it override tileset .prf files. Such addition would make adding and assigning new object to tileset very pleasant and easy

Right now to add or reassign object you need to edit 5 different .prf files with the same name.. It's hell mess. Even if it's only 1 tileset to modify - having everything in one file is so great DD

[tangar]

Yayyy! Thank you It's alright for now

*rubs his hands in anticipation* Time to poison some food.. poor things...

[takkaria]

It's not pleasant but the following would give you a 1/4 chance of poison:

effect:RANDOM
effect:NOURISH
dice:6000
effect:NOURISH
dice:6000
effect:NOURISH
dice:6000
effect:TIMED_INC:POISONED

[tangar]

/rfe
add possibility to assign certain chance for an item to produce certain effects. EX:
- assign ..% chance that food ration would be rotten (or poisoned ) and would make player sick for a while.

Something like
random:[chance]:[effect type]:[effect]...
eg:

name:& Ration~ of Food
graphics:,:U
type:food
properties:0:8:3
alloc:40:0 to 50
pile:100:1d5
effect:NOURISH
dice:6000
random:1:TIMED_INC:POISONED
msg_self:That tastes good.
desc:This nutritious but fairly bland food is familiar to anyone contemplating
desc: long journeys.

Actually my dream to have 'proper' rotten rations, but I suppose it's too hard to implement such behaviour.. So they would be the same as normal rations (kinda 'mimic'-items), and you would understand that they are bad only after you would eat them. But I suppose it's too hard to implement such behaviour, cause rotten and common items won't stack in a pile. What do you think?

[tangar]

Great!

I wanna add 'curses' which induce hunger; like inverse 'slow digestion', but it seems there is no way to implement it without modifying the code; so it would be splendid to have customization in this field!

[Nick]

Note that this will have the odd behavior of "filling you up" to Hungry if you trigger the trap when Weak.

I guess the ideal would be to subtract some amount from the player's hunger counter, but I'm not familiar enough with how these effect specifications work to know if that's possible.

Probably the correct thing to do, in fact, is to set hunger as another player timed status effect - this should work fine now there is no gorged status.

Filing that now.

[tangar]

YAY! Takkaria, thank you very much!! DD

[takkaria]

You can just use the number with SET_NOURISH, e.g.

effect:SET_NOURISH
dice:1999

is 1 hunger step into 'Hungry'.

[tangar]

Today this silly newbie (I am) tried to customized the hunger state from traps.. To create my own trap.

# hunger

name:trap:hunger trap
graphics:^:light yellow
appear:1:10:0
visibility:d50
flags:TRAP | FLOOR | MAGICAL | ONETIME
effect:SET_NOURISH
dice:$B
expr:B:FOOD_FAINT:- 1
desc:A trap that makes you very hungry.
msg:You feel yourself very hungry!

But. I wanna make trap less severe. I've looked with my wide blank eye @ source code and found some staff

player-common.h

#define PY_FOOD_MAX 17000 /* Food value (Bloated) */
#define PY_FOOD_FULL 10000 /* Food value (Normal) */
#define PY_FOOD_ALERT 2000 /* Food value (Hungry) */
#define PY_FOOD_WEAK 1000 /* Food value (Weak) */
#define PY_FOOD_FAINT 500 /* Food value (Fainting) */
#define PY_FOOD_STARVE 100 /* Food value (Starving) */

player-timed.c

if (v < PY_FOOD_FAINT) new_aux = 0;
else if (v < PY_FOOD_WEAK) new_aux = 1;
else if (v < PY_FOOD_ALERT) new_aux = 2;
else if (v < PY_FOOD_FULL) new_aux = 3;
else new_aux = 4;

Then I've started experimentation with trap effect..

effect:SET_NOURISH
dice:$B
expr:B:FOOD_FAINT:- 1

I've tried loads of different effects like:
expr:B:FOOD_WEAK:- 1
expr:B:FOOD_ALERT:- 1
...
even to exotic ones (good example when you do something which you have no clue):
expr:B:FOOD_FAINT:+ 1

..

Then I recognized that this could be a boolean

Damm. Then I've tried to use:

effect:NOURISH

with '-' value.. like:
effect:NOURISH
dice:-4000

it didn't work.

/rfe
Would be fun to have some customization on hunger state. At the same time maybe someone could advice me certain trick, maybe it's possible to do it in current version?

Thanks!
