WHY does this CreateDefaultSubobject return a nullptr? I can see nothing wrong with it. I copied this line for line from the wheeled vehicle example, but changed to simple movement.
header
private:
UPROPERTY(Category = Vehicle, EditAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
UWheeledVehicleMovementComponent* move;
cpp
Aprogramatic_vehicle_c::Aprogramatic_vehicle_c()
{
move = CreateDefaultSubobject<UWheeledVehicleMovementComponent, USimpleWheeledVehicleMovementComponent>(TEXT("Move"));
}
