Extention builder needed...

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>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 > AtoBback)
    {
          return 1;
      }else if(AtoBforw < 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>back) then
return back;
else
return forw;
end
end

function way(a,b)
forw=abs(a-b);
back=abs(a-(b-360));
if(fow>back) then
return 1
else if(forw<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.

MMF 2 doesn't handle if statements very well, and such a thing would be "easier" to do via script.

I actually like multiple ways of doing the same thing, thats where MMF really has its power <img src="/center/images/graemlins/laugh.gif" alt="" />.

Immediate If might actually be easier than that.

why even use an if? just use min(AtoBBack, AtoBforw).

Because he's not doing a min() calculation as far as I can tell.

Thanks vortex2 for the LUA script! (Now I know how to use LUA too!)

Sorry for not responding anytime sooner, I never have time to get on my computer. (School :P)

EDIT: Two things:

Is it possible to have the tab button enabled for the text box? I NEED tab to organize my programming.
And now that I have the script in the LUA object, how do I run it? The help file didn't really help me.
Thanks :P

Use the Call function action.

for example call function "Distance" with "a|b" (a and b would be your values seperated by a "|") with 1 return.

You would then get this return after calling the function through an expression.

... and how do you get the return after calling the function through an expression?

What is an 'index value'?


The new forums are wierd...

Bump... because I really need to know.
