I'm doing a bit of programming for the PSP in C/C++, using the pspdev thing for compiling.

I'm trying to make a function to print in color.

Basically, I call my function, giving it a string I want to print, and a RGBA (red, green, blue, alpha) hex color code. Then my function should print the message in that color.

I have some code to do this:

void	printStuff( long colour, char *message )
{
	int r;
	int g;
	int b;
	int a;
	int c;

	c = colour;

	r = c / 0x01000000;
	c -= (r * 0x01000000 );

	g = c / 0x00010000;
	c -= (g * 0x00010000 );

	b = c / 0x00000100;
	c -= (b * 0x0100 );

	a = c;


	pspDebugScreenSetTextColor((a * 0x1000000) + (b * 0x10000) + (g * 0x100) + (r));
	pspDebugScreenPrintf(message);

}

In theory, if I use:

printStuff(0xFF7F0FF, "Hello");

...it should print the text "Hello" in orange.

It compiles fine, and when I do the sums on a calculator, it works fine.

But when I run it on the PSP, it doesn't work at all...



I think the problem lies when I'm doing "r = c / 0x01000000 ;", like it can't divide properly or something.

Does anyone know why this doesn't work?

Or, can anyone think of a better way of getting r, g, b and a from the color?

Thanks.

I have no idea what to do on this but gabe said something about patching your mainframes before....

lol the statement is justified.

Severe bumpage going on here...

And if anyone actually cares, the devision works strangely on the PSP. The way I did it was as follows:

void	printHex( unsigned long color, int x1, int y1, char *str)
{
	char message[999];
	unsigned r1;
	unsigned g1;
	unsigned b1;
	unsigned a1;
	unsigned char r;
	unsigned char g;
	unsigned char b;
	unsigned char a;

	if( strlen( str ) < 800 ) {
		sprintf( message, "%s", str);
	} else {
		sprintf( message, "String too big (%d chars)", strlen(str) );
	}

	r1 = color & 0xFF000000;
	g1 = color & 0x00FF0000;
	b1 = color & 0x0000FF00;
	a1 = color & 0x000000FF;

	a = (char)(a1);
	b = (char)(b1 >> <img src='http://www.ibotmodz.net/forum/public/style_emoticons/<#EMO_DIR#>/dirol.gif' class='bbc_emoticon' alt='8)' />;
	g = (char)(g1 >> 16);
	r = (char)(r1 >> 24);

	pspDebugScreenSetXY(x1,y1);
	pspDebugScreenSetTextColor((a * 0x1000000) + (b * 0x10000) + (g * 0x100) + (r));
	pspDebugScreenPrintf(message);
}
