What is "mCap"?

by Demolishun · in Torque Game Engine · 09/24/2004 (8:25 pm) · 2 replies

Hello,
I am playing with the icon tutorial:
http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=4124

In the code it uses a call to "mCap" in script. Does anyone know what this is? Torque 1.2 gives me an error saying function cannot be found. I assume this is not standard Torque.

Here are the calls from IconCtrl.cs:
// keep icon inside gui object
%x = mCap(getWord(%this.position, 0), 1, (getWord(%parent.extent, 0)-getWord(%this.extent, 0)));
%y = mCap(getWord(%this.position, 1), 25, (getWord(%parent.extent, 1)-getWord(%this.extent, 1)));

These both fail for function not being found. As is the code will work, but I for the life of me cannot think about what math function this would be.

Thanks,
Frank

    I'm guessing it was a console function for enforcing a minimum and maximum boundary on a value. I'm guessing the first parameter is the number to be capped, the second is the minimum allowed value and the third is the maximum allowed value; the result would equal the min/max if under/over them respectively, otherwise the result is the same as the input value.

    Again this is a total guess, but it makes sense in the context of the script that is using it. I checked the source and there is no reference to it at all there. It could be replaced easily with a script function with something like:

    function mCap(%inputValue, %minimumValue, %maximumValue)
{
   %returnValue = %inputValue;

   if (%returnValue < %minimumValue) 
   {
      %returnValue = %minimumValue;
   }

   if (%returnValue > %maximumValue) 
   {
      %returnValue = %maximumValue;
   }

   return %returnValue;
}

    Assuming of course the positions and uses of the parameters are what I think they are. Perhaps someone who remembers the function can enlighten us for sure.
