Item id's over 32k?

[bimbi]

Hey community,

i have a little question. I know where i can change the maximum of item ids, but my problem is now i saw this notice

// 32k array entries in array (the rest goes to the db)

What does it really mean? Is this only for txt item_db? I think so, because the sql itemdb is already in a db O.o and doesn't need an array.

BTW: Is there any known problem if i increase my item_db to 50k?

YES THE MAX, BECAUSE THE CLIENTE IS HEXADECIMAL CODE

Yeah that what sensei334 is trying to say, its like this too 

ragnarok max zeny on hand = 2,147,483,647

maplestory max meso on hand = 2,147,483,647

Server msg:

Recompile your server after you do things mention in the quote!

in the past eathena can also support ItemId bigger than 32767

 

if you did the things in the quote and >>>(RECOMPILE Your Server)<<<

after you did that it should all work.

 

Item Id actually can be more Like in hercules it does support more than 32767

if the item_id (nameid inside item_data struct) is defined by short data type (uint16).

struct item_data {
uint16 nameid;

Maximum value of positive value is 32,767 (2^15-1)

I just know it, don't what is effect if use __int32 or larger, maybe about the performance I think and memory capacity

so i have to figure out, but i dont really kow how to test it - i don't see a performance reduction. Maybe it will lower my performance if i change the int. It would be great if somebody could tell me if he/she has tested it before.

Server msg:

: DB error - data of field 'nameid' was truncated.

[Debug]: column - 1

[Debug]: data - type=UNSIGNED MYSQL_TYPE_LONG, length=2

[Debug]: buffer - type=MYSQL_TYPE_SHORT, length=2

 

What I did:
 

on src\map\itemdb.h:

 

I changed

 #define MAX_ITEMDB 0x8000

 

to

 

#define MAX_ITEMDB 0x10000

 

and

 

struct item_data {

    uint16 nameid;

    char name[iTEM_NAME_LENGTH],jname[iTEM_NAME_LENGTH];

 

to

 

struct item_data {

    uint32 nameid;

    char name[iTEM_NAME_LENGTH],jname[iTEM_NAME_LENGTH];

 

I used item IDs starting from 50000
