RawDrawUnfilledCircle (SOLVED)

[Akumayo]

Is it possible, even with a workaround, to make AGS draw an unfilled circle, rather than the filled ones it draws currently.Ã,  The ability of the engine to do this is crucial to the user-end of my game...

-Thanks in advance, Akumayo

Of course, using the RawDrawLine function.

[EDIT] Heh, I started writing it with radians, but then changed it half way because I was sure CJ had "dumbed down" the functions to take degrees Silly me. Code erased because Wretched's is obviously better (and working!).

 Maths.Sin() and cos() use radians. Also you could get a duplicate arc due to floating point precision with < 360.0

Code: ags

function RawDrawUnfilledCircle(int x, int y, int radius)
{
Ã,  float farcs;
Ã,  
Ã,  float fradius=IntToFloat(radius);
Ã,  float t0;
Ã,  float t1;

Ã,  farcs=2.0*Maths.Pi*fradius/10.0; //Try to keep big circles smooth
Ã,  farcs=IntToFloat(FloatToInt(farcs));
Ã,  if (farcs<18.0) 
Ã,  {
Ã,  Ã,  Ã, farcs=18.0;
Ã,  }
Ã,  
Ã,  
Ã,  float a=0.0;
Ã,  while (a<farcs)
Ã,  {
Ã,  Ã,  t0=(a)*Maths.Pi*2.0/farcs;
Ã,  Ã,  t1=(a+1.0)*Maths.Pi*2.0/farcs;
Ã,  Ã,  
Ã,  Ã,  RawDrawLine(x+FloatToInt(fradius*Maths.Cos(t0)), 
Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  y+FloatToInt(fradius*Maths.Sin(t0)), 
Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  x+FloatToInt(fradius*Maths.Cos(t1)), 
Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  Ã,  y+FloatToInt(fradius*Maths.Sin(t1)) ); 
Ã,  Ã,  a=a+1.0;
Ã,  }

}

Wow Wretched!  Thanks alot.  Now I know how to go about scripting something like this!
