C++ (Cpp) EntityInstancePtr Beispiele

Beispiel #1

std::pair< EntityNode*, EntityInstanceNode*> EntityNode::CreateInstance( const Asset::EntityInstancePtr& entity )
{
    EntityNode* artClass = &Get( entity->GetEntity()->GetPath() );
    M_EntityNode::iterator instItor = artClass->m_Instances.find( entity->m_ID );

    EntityInstanceNode* entityNode = NULL;
    if( instItor == artClass->m_Instances.end() )
    {
        MFnDagNode nodeFn;
        MObject instanceObject = nodeFn.create( EntityInstanceNode::s_TypeID, entity->GetName().c_str() );
        nodeFn.setDoNotWrite( true );

        entityNode = static_cast< EntityInstanceNode* >( nodeFn.userNode() );

        artClass->m_Instances[ entity->m_ID ] = entityNode;
        entityNode->SetBackingEntity( entity );
        entityNode->Show( *artClass );
    }
    else
    {

        entityNode->SetBackingEntity( entity );
    }

    return std::pair< EntityNode*, EntityInstanceNode* >( artClass, entityNode );

Beispiel #2

    m_UID = m_Entity->m_ID;

    m_Plug.setAttribute( s_ArtFilePath );
