APhysicsVolume is undefined

Development Programming & Scripting
1

I tried to add code to Moveforward function of basic Character in Third person project:

if (GetPawnPhysicsVolume()->bWaterVolume)
	{
		const FRotator Rotation = Controller->GetControlRotation();
		const FVector Direction = FRotationMatrix(Rotation).GetUnitAxis(EAxis::X);
		AddMovementInput(Direction, Value);
		return;
	}

But I get error about Physics Volume type being undefined:

1>D:\Tim\UE4\Projects\Test3Person\Source\Test3Person\Private\Test3PersonCharacter.cpp(95): error C2027: use of undefined type 'APhysicsVolume'
1>          D:\Tim\UE4\UnrealEngine\Engine\Source\Runtime\Engine\Classes\Components/SceneComponent.h(70) : see declaration of 'APhysicsVolume'
1>D:\Tim\UE4\Projects\Test3Person\Source\Test3Person\Private\Test3PersonCharacter.cpp(95): error C2227: left of '->bWaterVolume' must point to class/struct/union/generic type

How to resolve this problem?
