Re: find parameters that are linked by expression

[Guillaume Laforge <guillaume(at)alamaison.fr>]

Hi Martin,

You can find the connected "object A" of an expression operator with the 
Target propertie.

To find a parameter with an expression using the object A, you must 
search for all the parameters in your scene. If a parameter expression 
(parameter source) use "object A" as a target then it is the parameter 
you want.

Example :

//****************************
MyParam = Dictionary.GetObject("null").posx;

gl_FindExpressionTarget0(MyParam);


function gl_FindExpressionTarget0(MyParam)
{
   var allObjects = ActiveSceneRoot.FindChildren(  );

   oEnumObjects = new Enumerator( allObjects ) ;
   for (;!oEnumObjects.atEnd();oEnumObjects.moveNext() )
   {
       var obj = oEnumObjects.item() ;
       var oParams = obj.Parameters;

       oEnum = new Enumerator( oParams ) ;
       for (;!oEnum.atEnd();oEnum.moveNext() )
       {
           var oParam = oEnum.item() ;
           if(oParam == obj.roty)
           {
               if(oParam.Source)
               {
                   var oExpr =oParam.Source;
                   var oTarget = oExpr.InputPorts(0).Target2.FullName;
                   if(oTarget == MyParam)
                   {
                       LogMessage( oParam )
                   }
               }
           }
       }
   }
}
//*****************************

Hope this help,

Cheers
