v5.0
Checks if an object is a member of the group.
For large numbers of objects, it's better to use SIObject.IsEqualTo on each member
(and ProjectItem.BranchFlag, if you
want to know if the object is a branch member).
oBoolean = Group.IsMember( Member, [BranchMember] ); |
Boolean
True if the object is a member, and False otherwise.
| Parameter | Type | Description |
|---|---|---|
| Member | SceneItem | The object to check. |
| BranchMember | Boolean | True to test if the object is a branch member.
Default Value: False |
// This example shows how to test a group for branch members.
NewScene(null, false );
var a = ActiveSceneRoot.AddGeometry( "Cube", "MeshSurface", "A");
a.length.value = 2;
var b = a.AddGeometry("Cube", "MeshSurface", "B");
b.length.value = 2;
Translate( b, 5 );
var c = b.AddGeometry("Cube", "MeshSurface", "C");
c.length.value = 2;
Translate( c, 5 );
// Create a group
var group = ActiveSceneRoot.AddGroup();
// Add members to the group
group.AddMember( a, true );
group.AddMember( b, false );
selection.clear();
selection.add(a);
selection.add(b);
var eSelection = new Enumerator(selection);
// Check if the selected object is a group member.
for ( ; !eSelection.atEnd(); eSelection.moveNext() )
{
var obj = eSelection.item();
if ( group.IsMember( obj, false ) )
logmessage( "selected object '"+ obj.name +"' is a group member");
if ( group.IsMember( obj, true ) )
logmessage( "selected object '"+ obj.name +"' is a branch group member");
}
//INFO : selected object 'A' is a group member
//INFO : selected object 'A' is a branch group member
//INFO : selected object 'B' is a group member
