◆ MoveEntityAndDescendantsToListAndReplaceWithEntityId()

static bool UiElementComponent::MoveEntityAndDescendantsToListAndReplaceWithEntityId ( AZ::SerializeContext &  context,
AZ::SerializeContext::DataElementNode &  elementNode,
int  index,
AZStd::vector< AZ::SerializeContext::DataElementNode > &  entities 
)
static

Helper function used during conversion of old format canvas files. Called from UiCanvasFileObject::VersionConverter and PrefabFileObject::VersionConverter. In the old format child entities were referenced by Entity* rather than EntityId so each entity had all of its children nested under it in the file. In the newer format, that was introduced when slice support was added, the entities are owned by the root slice and referenced by entity id. An index of -1 is used when this is called on the root element of the canvas, otherwise index is the index of the child entity withing the children container.

The documentation for this class was generated from the following file:
