Using the Function: Createdvar

To use this function, this code needs to be present within the file or from an include:

Code:: createdvar(varname, vardefault, min, max, type)
{
if(type == "int")
{
   if(getdvar(varname) == "")
      definition = vardefault;
   else
      definition = getdvarint(varname);
}
else if(type == "float")
{
   if(getdvar(varname) == "")
      definition = vardefault;
   else
      definition = getdvarfloat(varname);
}
else
{
   if(getdvar(varname) == "")
      definition = vardefault;
   else
      definition = getdvar(varname);
}

if((type == "int" || type == "float") && min != 0 && definition < min)
   definition = min;

if((type == "int" || type == "float") && max != 0 && definition > max)
   definition = max;

if(getdvar( varname ) == "")
   setdvar( varname, definition );

return definition;
}

To use it to create string dvars:

Code:: createdvar( <dvar>, <default value>, <empty>, <empty>, <type> )

e.g.

createdvar( "scr_show", "hey", "", "", "string" );

To use it to create float dvars:

Code:: createdvar( <dvar>, <default value>, <minimum value>, <maximum value>, <type> )

e.g.

createdvar( "scr_speedtime", 1.32, 1.2, 1.4, "float" );

To use it to create int dvars:

Code:: createdvar( <dvar>, <default value>, <minimum value>, <maximum value>, <type> )

e.g.

createdvar( "scr_speedwait", 2, 1, 4, "int" );

This function is very useful for quickly making dvars and ensuring they have the correctly default values, rather than using annoying rows of if statements.
