protected:    // Called when the game starts or when spawned    virtual void BeginPlay() override;    // The movement from the previous frame    FVector2D lastInput;

2. We will then need to initialize the variable inside of the class constructor:

// Sets default valuesAWarrior::AWarrior(){    // Set this character to call Tick() every frame. You can turn      // this off to improve performance if you don't need it.    PrimaryActorTick.bCanEverTick = true;    lastInput = FVector2D::ZeroVector;}

3. Update the ::Forward, ::Back, ::Right, and ::Left functions, as follows:

void AWarrior::Forward(float amount){    // We use a += of the amount added so that when the other   // function modifying .Y (::Back()) ...
