hey, i need help with changing the action of an object when i already have
the object number. heres the code i have:

aw_int_set (AW_OBJECT_OLD_NUMBER, screenNumber);
aw_string_set(AW_OBJECT_ACTION,newDes);
aw_object_change();

so, can anyone help me? :) i keep on getting an error 204:
RC_CANT_FIND_OLD_ELEMENT, so not sure what im doing wrong, since im pretty
sure the object number is right, i get it when the user clicks the screen.
:)

[View Quote] You need to provide the address of the object too:

Excerpt from the SDK help:

"
The object to be changed is uniquely identified by the attributes AW_OBJECT_OLD_NUMBER, AW_OBJECT_OLD_X, and AW_OBJECT_OLD_Z. These values are typically taken from the attributes AW_OBJECT_NUMBER, AW_OBJECT_X, and AW_OBJECT_Z within the context of either the AW_EVENT_CELL_OBJECT or AW_EVENT_OBJECT_ADD event.

XAMPLE

int rc;

aw_int_set (AW_OBJECT_OLD_NUMBER, 1278643762);
aw_int_set (AW_OBJECT_OLD_X, 0);
aw_int_set (AW_OBJECT_OLD_Z, 0);
aw_int_set (AW_OBJECT_X, -200);
aw_int_set (AW_OBJECT_Y, 0);
aw_int_set (AW_OBJECT_Z, 0);
aw_int_set (AW_OBJECT_YAW, 0);
aw_int_set (AW_OBJECT_TILT, 0);
aw_int_set (AW_OBJECT_ROLL, 0);
aw_int_set (AW_OBJECT_OWNER, my_number);
aw_string_set (AW_OBJECT_MODEL, "street1.rwx");
aw_string_set (AW_OBJECT_DESCRIPTION, "Cornerstone");
aw_string_set (AW_OBJECT_ACTION, "create sound xyz.mid");
if (rc = aw_object_change ())
printf ("Unable to change object (reason %d)\n", rc);
else
puts ("Object changed");

Are you basing it off a query? Only ever deal with 'live' data, thats data
that you know exists....

While the code Andras posted its correct, you have to be absolutly sure that
you have the live data for the objects X and Z coordinate, as well as its
number... then use this...

aw_int_set(AW_OBJECT_OLD_NUMBER, lngObjectNumber);
aw_int_set(AW_OBJECT_OLD_X, lngObjectX);
aw_int_set(AW_OBJECT_OLD_Z, lngObjectZ);

That will fully reference what you are after... coordinate X and Z are
needed for the database to find the object in a relitivly quick time... can
you imagine trying to query 10,000,000 database records every single time
you change an object? There is always a user-based local store but thats
getting too much to elaborate on here.

correct.

that would certainly help to see where is the problem :)

alright, well heres my complete code! i guess it code also be helpful to
people if they are tring to make like a projector bot or something :), or
just a win 32 console which gets info from a txt file, well, heres the code!
p.s: its not commented, and is very very messy! ^_^: oh, to get it to work,
you will need 2 text files, one called cit.txt and the other called
pictures.txt, check the code to see the infomation needed, quite obvious i
think. but i'll put a sample txt file here anyway.
