Extention builder needed...

**Durnus** · 30th September 2006, 05:09 PM

I need an extention that can do these two things, nothing more.

Code:

integer distance(int A, int B)
{
     int AtoBforw = abs(A-B);
     int AtoBback = abs(A-(B-360));
     if(AtoBforw&gt;AtoBback)
     {
          return AtoBback;
      }else{
         return AtoBforw;
     }
}
integer way(int A, int B)
{
     int AtoBforw = abs(A-B);
     int AtoBback = abs(A-(B-360));
     if(AtoBforw &gt; AtoBback)
     {
          return 1;
      }else if(AtoBforw &lt; AtoBback){
         return -1;
     }else{
          return 0;
      }    
}

Sorry if you don't understand it, it is meant to get the distance between two angles and the direction you need to go to get there.

Also sorry if some of my syntax is wrong, I've never programmed anything in C++ before.

Why not get the free edition of visual studio (found here) and make the extension yourself? It shouldn't be too hard to make such a simple extension (though I speak as one who has never tried to make an extension)

I don't see why you can't use Lua to do this...

looks perfectly possible to use Lua

Response:

Don't know how to install the SDK (from experiance, installing SDKs is a pain in the neck)

Don't know how to use LUA.

:P

Code:

function distance(a,b)
forw=math.abs(a-b);
back=math.abs(a-(b-360));
if(forw&gt;back) then
return back;
else
return forw;
end
end

function way(a,b)
forw=abs(a-b);
back=abs(a-(b-360));
if(fow&gt;back) then
return 1
else if(forw&lt;back) then
return -1
else
return 0;
end
end

Should work.

But... Why use Lua or make an extension to do that ? It's two simple formulas that you can make directly in MMF2... O_o

If you want to be able to use it with expressions functions, use Power Function object or an equivalent.
