The following line of code is generating a link error:
const FCollectionVectorParameter* BoatPosParam = BoatPositionCollection->GetVectorParameterByName(TEXT("BoatBos"));
Link error:
error LNK2019: unresolved external symbol "public: struct FCollectionVectorParameter const * __cdecl UMaterialParameterCollection::GetVectorParameterByName(class FName)const
Seems odd, I can see the implementation in ParameterCollection.cpp, why can’t the compiler find it?
Update: I see this was in fact the wrong method to call, instead I need to get the instance. This also causes a link error
Code:
UMaterialParameterCollectionInstance* ParameterInstance = GetWorld()->GetParameterCollectionInstance(BoatPositionCollection);
FLinearColor BoatPosOut;
bool Result = ParameterInstance->GetVectorParameterValue(TEXT("BoatPos"), BoatPosOut);
Link error:
error LNK2019: unresolved external symbol "public: bool __cdecl UMaterialParameterCollectionInstance::GetVectorParameterValue(class FName,struct FLinearColor &)const
