| Thanks for your help
I saw the funcion in lua_scripting, and you used it in the original startup.lua (or its equivalent to get the player's name)
If I understand well, when it says "attempt to index local room (a nil value)", this means that he doesn't know what I'm trying to call, right ? something like an undeclared function.
I just did
function mob_byte()
local room = mud.room_info ()
...
end --function
I have this : mob_byte = require("mob_byte").mob_byte
in starup.lua
And mob_byte is called when a mob (called Byte) is created : Byte have an open_lua, then a call_lua calling mob_byte function | | Top |

| Which line exactly is the error on? I don't see how this line is indexing anything:
local room = mud.room_info ()

Ya, this doesn't return error, but as soon I try to use the "room", nil value blabla
For instance, got this local room = mud.room_info () in the beginning and player= room.first_person; few lines after.
player= room.first_person; returns the attempt to index local "room" (nil value)
note: my modified L_room_info does define a first_person attribute to the room
edit : I will look if I cannot do what I wanted directly with L_players_in_room | | Top |

| My code returns nil if the current character is not in a room:
static int L_room_info (lua_State *L)
{
CHAR_DATA * ch = L_getchar (L); /* get character pointer */
ROOM_INDEX_DATA * room = ch->in_room; /* which room s/he is in */
EXIT_DATA * pexit;
if (lua_isnumber (L, 1))
room = get_room_index( check_vnum (L) );
if (room == NULL)
return 0; /* oops - not in room or specified room does not exist */
So you need to look into whether ch->in_room is NULL or not. Maybe use gdb to get to the bottom of it? |
