Okay, seems like I have everyone here that I wanted ;-)
For your information there are three (excluding myself) subscribers now
-- ABCGi, Ilya Bely and Igor Savin.
Currently this list will probably be low-traffic (especialy that some
of us have exams now) but I hope that in the future this list will
become for Carceri what gearhead_dev is for GearHead. As for my activity
on Carceri itself it will be very low the next three weeks -- I have
three exams -- on the 13th, 16th and 20th of June. Still, I know myself,
so probably I will be coding Carceri when I will be pressed by the
deadlines at most :-). Afterwards probably between 5th and 24th of July
I'll probably be on vacation. But after that the hardcore development
will start ;-).
Anyway, to go back on topic -- here's an example of how the Carceri
Data File format looks like. It is still beta, so changes in the way it
looks can be made without problem, so I await your commens. "//" are
comments after which I provide explanations.
Let's take a tile (cell) for example:
TILE "st_closeddoor" [st_wall] ( // the data type "TILE", id:"st_closeddoor
// in the square brackets we have
inheritance
Name : "closed door"; // self-explanatory
LightColor : #brown; // This should be a number, but the
engine supports
// pre-defined constants, and resolves
them at run
// time.
Picture : '+'; // characters are in '' quotes, strings
in ""
ActivateTo : @st_opendoor; // "@" sign denotes a reference to
another object
ActivateMsg : "You open the door.";
BloodTo : 0; // This would be a reference to what the
tile changes
// if blooded over
flags : [tfBlockMove | tfBlockSight | tfOpenable];
// set of flags.
)
Another one, without comments:
TILE "st_stairup" [st_floor] (
Name : "stairs leading upwards";
LightColor : #yellow;
Picture : '<';
ActivateTo : @st_stairdown;
ActivateMsg : "You climb upwards.";
BloodTo : 0;
Flags : [ tfStairUp | tfNoChange ];
OnEnter : $onenter_stairs;
)
The new thing here is the OnEnter field. Fields starting with On are
script hooks. Variables starting with "$" are references to Lua
functions. This example is artificial, for the stairs do not need any
"OnEnter" script tough.
There are more fields in a TILE type data, but the rest are inherited
from st_wall. If not present, the system tries to guess reasonable
defaults.
FORWARD "st_bloodycorpse"
NPC "wolf" (
Name : "wolf";
Picture : 'w';
Color : #lightgray;
SpeedMove : 50;
Corpse : @st_bloodycorpse;
HitPoints : 2;
OnDie : $ondie_wolf;
)
In the above data we see a special type called "FORWARD". It is needed
because st_bloodycorpse is defined later. The data here is pretty random
and simple tough ;-).
Any comments, questions, suggestions? I have a nice syntax coloring for
this data in Texturizer. I can post the whole current data file if
anyone is interested.
