Sure, create a panel.

Code:

---

 
panel my_debug_pan
{
	digits 225,225,"angle 1 %.5f",digit_font,1,sword.roll;
	digits 225,275,"angle 2 %.5f",digit_font,1,sword.tilt;
	digits 225,325,"angle 3 %.5f",digit_font,1,sword.pan;

	layer = 3;
	flags = visible;
}

---

Replace sword.roll etc., with whatever you want to see. Make sure you have a font set up.

Code:

---

 
font digit_font = <digfont.pcx>,12,16;
