i am trying to make the bmap property of my panel be something different depending on the number at index[0] of an array. So i'm trying to create the string
bmap = item4500_bmap;
and make it execute inside of the panel definition.

Code:

---

 
var itemMerchSlot1[13] = [6200, 1, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0];


string executeTestString = "bmap = item";
string item_num;
str_for_num(item_num,itemMerchSlot1[0]); 
str_cat(executeTestString, item_num);
str_cat(executeTestString, "_bmap;");


PANEL merch_slot1_pan
{
	pos_x = 200;
	pos_y = 200;
	layer = 2;
	execute(executeTestString);
	digits (30, 35, 2, _a4font, 1, slot2_var[1]); 
	on_click = slot_click_func;
	flags = refresh, d3d;
}

---

the errors i get are...


< str_for_num(item_num,itemMerchSlot1[0]);>
merchant.wdl 9:0 Error(29): Keyword unknown str_for_num

< str_cat(executeTestString, item_num);>
merchant.wdl 10:0 Error(29): Keyword unknown str_cat

< str_cat(executeTestString, "_bmap;");>
merchant.wdl 11:0 Error(29): Keyword unknown str_cat

< execute(executeTestString);>
merchant.wdl 19:0 Error(212): Keyword unknown merch_slot1_pan execute

< }>
merchant.wdl 23:-1 Error(0): Syntax error - merch_slot1_pan

you have to put the str_for_num and str_cat lines in a function, else it eill indeed give you that error... that's the only thing i can think of, since i use that kind of code all the time, and it does work properly for me.
give it a try

regards,

ok, there are no more errors being generated now; however, the panel bmap is not able to switch to the item4500_bmap

is there something wrong with the code:

merch_slot1_pan.bmap = item4500_bmap;

when item4500 is declared prior to this code, but in another file.

ok there's nothing wrong with the assignment statement, but the str_cat isn't generating the string properly. I'll run a test to see what string is being generated exactly.

I think the problem lies here:
string item_num;

if you declare it like this, item_num now is an empty string with 0 places to put characters in. This means that if you want to add text to it, the text is simply discarted because there is no place.

string item_num = "#5";

This however gives you a string with room for 5 characters. If you now put something in it (in your case, str_for_num puts something in it), the text is not discarted anymore because there is room for it. The first 5 characters of your text will now be displayed. Anything longer than 5 characters will still be cut off.

ok that was indeed the situation.
I also had to make room in the executeTestSTring string in order to have it stop truncating there as well, and then i had to use the str_cpy for the first bit of text. if i tried using the str_cat, i got a bunch of beeping, and some freezing of the system.
here's my final code.

Code:

---

var itemMerchSlot1[13] = [4500, 1, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0];
string executeTestString = "#40";
string item_num = "#5";

//panel for the merchant test

PANEL merch_slot1_pan
{
	pos_x = 200;
	pos_y = 200;
	layer = 2;
	bmap = empty_slot;
	digits(205, 37, item_num, _a4font, 1,  itemMerchSlot1[0] );
	on_click = slot_click_func;
	flags = refresh, d3d, VISIBLE;
}
////////////////////////////////////////



function makeSlot1()
	{
	str_cpy(executeTestString, "merch_slot1_pan.bmap = item");
	str_for_num(item_num, itemMerchSlot1[0]);
	str_cat(executeTestString, item_num);
	str_cat(executeTestString, "_bmap;");
   execute(executeTestString);
	}

thanks for you help both of you.
