    Fields

    Name Description
    ClearMissingReferences

    If set; all references to destroyed or missing entities will be set to Entity.Null before computing changes.

    When applying a change this is needed to patch references to restored entities (they were destroyed but are being brought back by the change set).

    Default

    The default set of options used by the EntityDiffer

    FastForwardShadowWorld

    If set; the shadow world will be updated with the latest changes.

    IncludeForwardChangeSet

    If set; the resulting EntityChanges will include the forward change set.

    IncludeReverseChangeSet

    If set; the resulting EntityChanges will include the reverse change set.

    This can be applied to the world to reverse the changes (i.e. undo).

    None

    Shortcut for "no options required".

    UseReferentialEquality

    If set, components are not compared bit-wise. Bit-wise comparison implies that two components that have references to entities that have the same GUID but different indices/versions are different. Similarly blob asset references to blob assets that have the same hash but live at different addresses will be considered different as well. This is often not desirable. For these cases, it is more apt to check that GUIDs and hashes match.

    ValidateUniqueEntityGuid

    If this flag is set; the entire world is checks for duplicate EntityGuid components.
