Simplifying

[Main]

Can I simplify this further?

If da > 0 then
  Begin
    If T<180 then
    Begin
      If ((Fx < 0) and (Fy < Ny)) or ((Fx > 0) and (Fy < -1 * Ny)) then dA:=dA + 180;
    End else
    Begin
      If ((Fx < 0) and (Fy > -1 * Ny)) or ((Fx > 0) and (Fy > Ny)) then dA:=dA + 180;
    End;
  End;

I know that

If a then b
  else
    c;

is possible.
but can

if e then c;

replace the b?


EDIT: I fixed the problem in the second embed, its still the same but I replaced "c end;" with "c;" which is correct but my question remains the same. I hope you guys can see what am on about.


EDIT 2: I realized my example can but I couldn't get it to work with what I have in the first embed. so it would be a if ..then within a if..then and within a if..then without begin and end if the final then ends up with a procedure like this;. Yeah this thing is a bit hard to explain.. I just want to see if i can save some space

It can be shortened, one sec.

if (da < 0) then
    Exit;
  if ((((Fx < 0) and (Fy < Ny)) or ((Fx > 0) and (Fy < -1 * Ny)) and (T < 180)) or (((Fx < 0) and (Fy > -1 * Ny)))) or (((Fx > 0) and (Fy > Ny)) and (T >= 180)) then
    IncEx(dA, 180);

if (T < 180) then n := 1 else n := -1;
if dA > 0 then
begin
  if (Fx < 0) and (n * Fy < Ny) then dA := dA + 180;
  if (Fx > 0) and (-n * Fy > Ny) then dA := dA + 180;
end;

This is cleanest, imo. (I'm pretty sure it works )
You could also replace the n's with Sin(T)/Abs(Sin(T)) (degrees, not radians!) and remove the first if..then statement, but that would probably take longer and will give an error if T = 180 (If it never will be then you can also just replace the first if..then statement with n := Sin(T)/Abs(Sin(T)), but again that'd probably be slower)

Yeah, I was gonna do something similar to Ogre's so nevermind .

thanks ogre, you actually fixed a mistake where I missed a begin and end in the first embed I posted.
