Description
Returns true if this actor belongs to the specified data layer asset. There is also an overload that accepts a UDataLayerInstance pointer.
Caveats & Gotchas
- • The overload taking FActorDataLayer is deprecated since UE 5.1. Convert data layers to assets using the UDataLayerToAssetCommandlet before calling this function.
- • Passing a null pointer always returns false rather than asserting — safe to call on unvalidated references, but make sure a false result is not silently masking a missing asset.
