Hi im finally getting around to learning script with Lite-C Workshops ,but i got a small problem already.

im on Workshop 03: Functions.
And every time i try to run my code it dont ,and i cant see a problem with it?.
i got to the part which my code is

////////////////////////////////////////////////////////////////////
#include <acknex.h>
#include <default.c>
var my_age = 19;
var days_a_year = 365;
var number_of_days; // we need to calculate this value
////////////////////////////////////////////////////////////////////
PANEL* pDisplay =
{
digits (10, 10, 5, *, 1, number_of_days);
flags = VISIBLE;
}
////////////////////////////////////////////////////////////////////
function main()
{
screen_color.blue = 150;
compute_days();
}
////////////////////////////////////////////////////////////////////
function compute_days()
{
number_of_days = my_age * days_a_year;
}
////////////////////////////////////////////////////////////////////


But every time i try to run it i get a error that says

Error im 'MAIN' line 17: 'compute_days' undeclared identifier

< compute_days();>
.Can't compile SCRIPT03.C

Please Help.

Hi there,
you have to put your function above the main function.
the enginge reads your script from the top till downside.
like reading a book.

...
..
.
///////////////////////////////////////////////////////////////
function compute_days()
{
number_of_days = my_age * days_a_year;
}
///////////////////////////////////////////////////////////////
function main()
{
screen_color.blue = 150;
compute_days();
}
///////////////////////////////////////////////////////////////

cheers

sorry i fegot to report back i did finally solve the problem, but still thanks.
And with what i learned so far i made this script from workshop 6 resouces

heres my script i made , you press buttion then text moves right.
its more easy then i though it would be.


////////////////////////////////////////////////////////////////////
#include <acknex.h>
#include <default.c>

STRING* aloha_str = "Welcome to Paradise Island!";
TEXT* greetings_txt =
{
pos_x = 10;
pos_y = 10;
string (aloha_str) ;
flags = VISIBLE;
}
BMAP* mouse_pcx = "mouse.pcx"; // bitmap used for the mouse pointer
function main()
{
video_mode = 7;
screen_color.red = 150;
mouse_map = mouse_pcx;
mouse_mode = 2;
while (1)
{
mouse_pos.x = mouse_cursor.x;
mouse_pos.y = mouse_cursor.y;
wait (1);
}

}

function move_text()
{
while(1)
{
wait(1);
greetings_txt.pos_x += 1;
}
}

//////////////////////////////////////////////////////////////////////

PANEL* main_pan =
{
bmap = "main.pcx";
pos_x = 250;
pos_y = 200;
button (250, 134, "quitclicked.pcx", "quitnormal.pcx", "quitover.pcx", move_text, NULL, NULL);
flags = OVERLAY | VISIBLE;
}

//////////////////////////////////////////////////////////////////////

btw, to solve that problem that zwecklos mentioned, in the future you can use something called function prototyping which means you write the function name before main(), and then you can make the function after main. Kinda confusing?...

#include <acknex.h>;

function hello_world();

function main()
{
beep();
hello_world();
}

function hello_world()
{
printf("hello world");
beep();
}

so the function at the top acts like a pointer to the function below main();
function prototyping is familiar in C++.

thank's
also is it possable to use "if" just to check 1 thing?.

for example
if shutdowngame is equal to 0 the games shuts down, with no "else" or "or"

i tryed this but it dont work
if (shutdowngame == 0)
{
sys_exit(NULL);
}

--------------------------------------------------------
Edit fixed it
while(1)
{
if (shutdowngame == 0)
{
sys_exit(NULL);
}
wait(1);
}
