From ac959bcc01a52f1738e439b0291dfb8b0a73b388 Mon Sep 17 00:00:00 2001 From: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> Date: Thu, 18 Nov 2021 15:06:58 -0800 Subject: [PATCH] Dragging an entity from outside the focused Prefab into it may crash the Editor (#5762) * Replace Instance References with EntityId of the Prefab Container (WIP) Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Use the invalid entity id for the root instance and get the root instance every time to prevent weird Prefab EOS shenanigans. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Revert unnecessary changes, fix IsOwningPrefabBeingFocused to match previous behavior. Disable some tests that no longer apply correctly due to the testing environment not relying on the Prefab EOS. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Fix minor typo in test comment Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> --- .../Prefab/PrefabFocusHandler.cpp | 131 +++++++++++------- .../Prefab/PrefabFocusHandler.h | 17 ++- .../Prefab/PrefabFocus/PrefabFocusTests.cpp | 8 +- 3 files changed, 99 insertions(+), 57 deletions(-) diff --git a/Code/Framework/AzToolsFramework/AzToolsFramework/Prefab/PrefabFocusHandler.cpp b/Code/Framework/AzToolsFramework/AzToolsFramework/Prefab/PrefabFocusHandler.cpp index 5b51944a75..744c53ef5a 100644 --- a/Code/Framework/AzToolsFramework/AzToolsFramework/Prefab/PrefabFocusHandler.cpp +++ b/Code/Framework/AzToolsFramework/AzToolsFramework/Prefab/PrefabFocusHandler.cpp @@ -98,7 +98,7 @@ namespace AzToolsFramework::Prefab } // Retrieve parent of currently focused prefab. - InstanceOptionalReference parentInstance = m_instanceFocusHierarchy[hierarchySize - 2]; + InstanceOptionalReference parentInstance = GetReferenceFromContainerEntityId(m_instanceFocusHierarchy[hierarchySize - 2]); // Use container entity of parent Instance for focus operations.
