Hi, I am trying to access the vector field actor I have placed into my world. I want to run the FilteredSample function on it. The code below causes a crash with error message “Unhandled Exception: EXCEPTION\_ACCESS\_VIOLATION reading address 0x000000000000005c”, so I assume the cast to the UVectorFieldStatic is failing.

How can I make this work?

Thanks!

AActor\* VecField = UGameplayStatics::GetActorOfClass(GetWorld(), AVectorFieldVolume::StaticClass());

UVectorFieldStatic\* StaticVectorField = Cast(VecField);

FVector Sample = StaticVectorField-\>FilteredSample(FVector(0.0, 0.0, 0.0), FVector(0.0, 0.0, 0.0));

I got it to work with:

AActor\* VecFieldActor = UGameplayStatics::GetActorOfClass(GetWorld(),  
AVectorFieldVolume::StaticClass());

AVectorFieldVolume\* VecFieldVolume = Cast\<AVectorFieldVolume\<\>\>(VecFieldActor);

UVectorField\* VecField = VecFieldVolume-\>GetVectorFieldComponent()-\>VectorField;

UVectorFieldStatic\* VecFieldStatic = Cast\<UVectorFieldStatic\<\>\>(VecField);

FVector Sample = VecFieldStatic-\>FilteredSample( FVector(0.0, 0.0, 0.0), FVector(0.0, 0.0, 0.0));
