Text Output in HUD

[mad mapper]

Hello,

i added a PERSISTANT variable.
The Scores are shown in MP in the lower right like that:
"Scores: 15"

I want to show the Variable I added in the lower left, so I edited the hud.menu in the ui Folder:


menuDef
{
name "lefthud"
fullScreen 0 // MENU_FALSE
rect 0 368 112 112 // Size and position of the menu
visible 1 // Visible on open


// Tells current credits of game********************************************** *******
itemDef
{
name credit_line
forecolor 1 1 1 1
rect 20 20 6 12 // (these positions are relative to the initial position of the menu)
// X pos, Y pos, char size, char height
}
[...]


Afterwards I added this code to CG_DrawHud

const char *creditStr = NULL;
creditStr = va("Credits: %i", cg.snap->ps.persistant[PERS_CREDITS]);
focusItem = Menu_FindItemByName(menuHUD, "credit_line");
if (focusItem)
{
UI_DrawScaledProportionalString(
focusItem->window.rect.x,
focusItem->window.rect.y,
creditStr,
UI_RIGHT|UI_DROPSHADOW,
focusItem->window.foreColor,
0.7);
}


It doesn't work. But if I type this:

char *creditStr = "Credits: ";

It works. I really don't know why.

The problem is definately with how you implimented persistant[PERS_CREDITS]);. You're going to have to detail what you did.

[mad mapper]

I think the bug is there because of the Output function because when I try this code

creditStr = va("%s: %i", "Credits", 0);
focusItem = Menu_FindItemByName(menuHUD, "credit_line");
if (focusItem)
{
UI_DrawScaledProportionalString(
focusItem->window.rect.x,
focusItem->window.rect.y,
creditStr,
UI_RIGHT|UI_DROPSHADOW,
focusItem->window.foreColor,
0.7);
}


nothing happens as well

[razorace]

hmmm. Well, my guess is that va doesn't like it when you use unnessisary alases for testing like that. You got a debugger?

[mad mapper]

Sorry, alases???
Don't know what that is

[razorace]

Err, I've never seen va used with static varibles for input like that.

[mad mapper]

Well,
const char *creditStr is no static variable but a pointer.

Look into the source of CG_DrawMenu. They use const char *scoreStr = va (...)
to print the scores into an AnsiString

Afterwards the output is made with CG_DrawProportionalString (...)

[razorace]

Yeah, but you're using two constant values for inputs onto the va. I beleive the easiest way to check this is to see what's in creditStr before the UI_DrawScaledProportionalString is called.
