Example: Custom Command Workaround for Both Output Arguments and Return Values

This example contains a command plug-in that you can call from languages that do not support output arguments. It allows those languages to get at the GetSkeleton command’s output argument (Index) as well as the returned skeleton objects.

' Load MyGetSkeleton command
function XSILoadPlugin( in_reg )
   in_reg.Name = "MyGetSkeletonPlugin"
   in_reg.Major = 1
   in_reg.Minor = 0

   in_reg.RegisterCommand "MyGetSkeleton","MyGetSkeleton"

   XSILoadPlugin = true
end function

' Define MyGetSkeleton command
function MyGetSkeleton_Init( in_ctxt )
   dim oCmd
   set oCmd = in_ctxt.Source
   oCmd.Description = "Version of GetSkeleton with no output arguments"
   oCmd.Tooltip = "Version of GetSkeleton with no output arguments"
   oCmd.ReturnValue = true

   dim oArgs
   set oArgs = oCmd.Arguments
   oArgs.Add "InputObj",siArgumentInput
   MyGetSkeleton_Init = true
end function

' Execute callback for the custom command
function MyGetSkeleton_Execute( InputObj )
   ' Call the GetSkeleton command and pack the output 
   ' argument and the return value in an array 
   set oSkel = GetSkeleton( InputObj, lIndex )
   aReturn = Array( lIndex, oSkel )

   ' Return the array
   MyGetSkeleton_Execute = aReturn 
end function
