i have resently been doing the Aum 83 struct workshop and i have hit a major problem:

str_cpy(name_str, Gun[counter].name);

This line produces a syntax error. I can not see anything wrong with it, they are both strings, and on of them is in a struct. ...have i done something completely wrong?

Can you post the Script? And what error? Screenshot or something would help.

look for counter, what does or is counter?
Variable? String? Define...(most likely not that)?


Since gun[counter].name
The red, I have never seen that...

name is a defined variable, gun is an entity.

maybe remove counter and see how that works without it.

it's called an indexer for an array

how can you store an array through an entity?

gun1
gun2
gun3

like that?

Then why isnt that workin?


Edit:

Its not an entity* its an Array to begin with =P



So what we need, is not the line of code, but what then engine is telling you in the error report; what is wrong with that code..?

here gun is a struct of entity (thats wat we assume).

@dakilla: post more code and the error u getting.

Once you try to access an element of an array, you need to separate
its properties from the container, like so

str_cpy(name_str, (Gun[counter]).name);

kk, it isnt a very long script, so ill post up the whole thing:


STRING* name_str = "#30";
STRING* sort_str = "#25";
STRING* inventwho_str = "#20";
var db_inventdate;


typedef struct
{
STRING* name;
STRING* sort;
STRING* inventwho;
var inventdate;
}Gun;


PANEL* gun_pan =
{
digits (280, 120, "Gun name: %s ", *, 1, name_str);
digits (280, 135, "Type: %s ", *, 1, sort_str);
digits (280, 150, "Invented by: %s", *, 1, inventwho_str);
digits (280, 165, "Invented in: %.0f", *, 1, db_inventdate);
flags = SHOW;
}

Gun database[1000];

STRING* temp_str = "#25";

var i = 0;

function main()
{
var file_handle;
file_handle = file_open_read("guns.txt");
while (i < 1000)
{
if (file_str_read(file_handle, database[i].name) == -1)
{
break;
}
else
{
file_str_read(file_handle, temp_str);
database[i].name = str_create("");
file_str_read(file_handle, database[i].name);
file_str_read(file_handle, temp_str);
database[i].inventdate = str_to_num(temp_str);
file_str_read(file_handle, temp_str);
database[i].sort = str_create("");
file_str_read(file_handle, temp_str);
file_str_read(file_handle, database[i].sort);
database[i].inventwho = str_create("");
file_str_read(file_handle, temp_str);
file_str_read(file_handle, database[i].inventwho);
i++;
}

}
file_close(file_handle);
}

function info_startup()
{
wait (-1);
var counter;
while (1)
{
if (key_cud)
{
while (key_cud) {wait (1);}
counter++;
}
if (key_cuu)
{
while (key_cuu) {wait (1);}
counter--;
}

counter = clamp(counter, 0, i-1);
str_cpy(name_str, Gun[counter].name);
// I havent done the others yet, as it's pointless until i fix the name.
wait (1);
}
}
