WChar functs

[keless]

Hey, I want to print out a score or FPS, which will obviously have different 'text' each time.

I will use the IGUIFont object to draw, but I need to figure out how to format the text. In plain char* I would do sprintf(mystr, "Score: %d", myscore); .. how do i do it for WChar?

TIA

Is this what you're looking for?

Code: Select all

wchar_t _Info[1024]; 
int fps = Driver->getFPS();
swprintf(_Info, 1024,"FPS: %d ",fps);

that will definately do it.

also, how would I do it with irr::core::stringw?

It's not possible to convert numbers into a irr:string with it's methds. You would have to use swprintf(). But that's a feature I should do on my TODO-list.

Pick up my function:

Code: Select all

void StringTextOut (gui::IGUIFont * font, int x, int y ,wchar_t text[], int d=-100)

{

	wchar_t tmp [1024];      
	if (d==-100)   
		swprintf ( tmp, 1024, L"%s", text );
	else
		swprintf ( tmp, 1024, L"%s = %d", text, d );

    font->draw ( tmp, 
                core::rect<s32>(x,y,300,80),
                video::SColor(255,255,255,255));	
}

plainn text:StringTextOut(font, 0 ,10, L"Programmed by Me" );

text + integer value
StringTextOut(font2, 0,20, L"Score: ", Score );

how about this one:

Code: Select all

void dout(const char *msg, ...)
{
	va_list argList;
	static char buffer[512] = { 0 }; //max 512 chars long

	va_start(argList, msg);
	vsprintf(buffer, msg, argList);
	
	va_end(argList);
// do something with 'buffer'
// i send my debug output to a file but you can
// send to console via os::Printer::log(buffer);
// or to screen using font->draw

// if you need to turn it into a wchar_t then do this
// wchar_t text[512];
// mbstowcs(text,buffer,512);
}

use it like this:
dout("There are %d ways to code a %s solution\n",10,"working");

just like a printf statement!
