Re: Script : Collection freeze selection.

[Bernard Lebel <3dbernard(at)gmail.com>]

I noticed something. I inserted a little loop that prints the content
of oKind, and I get nothing, only a blank line, and only one item was
printed. Then when the selection command runs, it says it is selecting
the objects under the model. At that point, nothing is appears
selected, but indeed I can't select anything. If I right-click on the
model and choose Lock Infos, then the model shows up as selected.


Anyway I rewrote your script and it works fine.

First, instead of creating the model collection in the global scope
and populating it in-place from a function, I create it directly in
the function and returns it to a variable (should also make your code
faster on larger scenes).

Second, I take extra steps to test collection counts, so if the count
is 0, nothing else happens.

Finally, notice the mofication I made with the findchildren call. I
suspect one of the problems of your script might be caused by the fact
that you used add() instead of additems(), so you were adding
collections (returned by findchildren()) instead of geometry. Remember
that add() works better with single element.

Here is the code:


// Get valid models
var oModels = FindKind( "Character" );

// Test if valid models were found.
if( oModels.count > 0 )
{
	// Create collection to store valid meshes under valid models
	var oMeshes = XSIFactory.CreateObject( "XSI.Collection" );
	
	// Collect polygon meshes under valid models
	for( var e = new Enumerator( oModels ); !e.atEnd(); e.moveNext() )
	{
		oMeshes.additems( e.item().findchildren( "", siPolyMeshType, null, true ) );
	}
	
	// Test if polygon meshes were found, if so, select them
	if( oMeshes.count > 0 )
	{
		selectobj( oMeshes );
	}
}



function FindKind( sKind )
{
	// Create collection to store valid models
	var oAllModels = XSIFactory.CreateObject( "XSI.Collection" );
	
	// Iterate all models
	for( var oAllModelsEnum = new Enumerator( activesceneroot.models );
!oAllModelsEnum.atEnd(); oAllModelsEnum.moveNext() )
	{
		var oCpset = oAllModelsEnum.item().properties( sKind );
		if( oCpset )
		{
			oAllModels.add( oAllModelsEnum.item() );
		}
	}
	
	return( oAllModels );
}

That has nothing to do with IE. Firefox also mangles the code formatting.
