Remarks

Returns or creates a shared struct associated to a given shared fragment set of values identified internally by a CRC. Use this overload when a different struct should be used to compute a CRC (i.e., UE::StructUtils::GetStructCrc32) and values can be provided as constructor arguments for the desired const shared fragment type e.g.,

USTRUCT() struct FIntConstSharedFragmentParams {

FIntConstSharedFragmentParams(const int32 InValue) : Value(InValue) {}

int32 Value = 0; };

USTRUCT() struct FIntConstSharedFragment : public FMassConstSharedFragment {

FIntConstSharedFragment(const FIntConstSharedFragmentParams& InParams) : Value(InParams.Value) {}

int32 Value = 0; };

FIntConstSharedFragmentParams Params(123); const FConstSharedStruct SharedStruct = EntityManager.GetOrCreateConstSharedFragment(FConstStructView::Make(Params), Params);

@params HashingHelperStruct Struct view passed to UE::StructUtils::GetStructCrc32 to compute the CRC @params InArgs List of arguments provided to the constructor of the desired fragment type FConstSharedStruct to the matching, or newly created shared fragment
