showing part of an array in digit - 07/12/11 08:02

Hi,
i have a little problem with showing a part of an array in a digit.

while definination and declaration seems to work

Code:

STRING * res[6];
	res[0] = "640 x 480";
	res[1] = "800 x 600";
	res[2] = "1024 x 768";

but as i want to show it via

Code:

digits(0, 0, " %s", "Arial#16", 1, res[1]);

it shows only "(null)"

also unfortunately

Code:

str_cpy(resolution, res[num]);

gives me an malfunction says: "Empty pointer in set_res" (set_res is the function called by the button from the panel with the digits above)

what i have to do to use the part of the array in the digits and iin other functions without exactly know thwat the player wants and witout writing a new function for each possibility?
i hope you can help me with it

greetings

STRING * res[6]; //Ok
res[0] = "640 x 480"; //No
res[1] = "800 x 600"; //No
res[2] = "1024 x 768";//No

You need to make a function that inits the strings:

res[0] = str_create("640 x 480");
res[1] = str_create(..);
..
Then, the digits will work

hmm anyhow the global declared string array isn't grey as the other global strings (and not shown in the code jumper on the right side)
also str_create isn't highlighted (?) and if i now call the function which shows the panel containing the digits the engine crashes (also it crahes instantly if the panel is shown at the beginning)

Code:

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

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

FONT* fnt_test = "arial#20";
STRING* str_res[6];

PANEL* pnl_res = {
//	digits(10, 10, "%s", *, 1, str_res[0]); //wont' work, string is not yet initialised!
	flags = SHOW;
}

void main(){
	
	str_res[0]= str_create("600x480");
	str_res[1]= str_create("800x600");
	pan_setstring(pnl_res, 0, 10, 10, fnt_test, str_res[0]);
	pan_setstring(pnl_res, 0, 10, 30, fnt_test, str_res[1]);
}

though you'd be better off using TEXT instead of PANEL

Code:

TEXT* txt_res = {
	font = fnt_test;
	pos_x = 300;
	strings = 6;
	string("600x480", "800x600", "1024x768");
	flags = SHOW;
}
