C++ character wont move, bp character will

[anonymous_user_311c2dae]

I created a papercharacter blueprint to prototype a character moving around the world. I used the add movement input node to do this. I have read that it does not update movement automatically and that I would have to do this in a tick function. However, it does just work automatically without me doing anything special in my tick to update movement.

Since that was working I started moving to C++ creating a subclass of APaperCharacter. I use the same add movement input function as I did in the blueprint, but it doesn’t move anymore. Why is the behavior different between the two versions, and how can I update movement in the C++ class?

This is the code related to the movement.

Aoverworld_player_char_c::Aoverworld_player_char_c()
{
	PrimaryActorTick.bCanEverTick = true;

	movement = GetCharacterMovement();
	movement->GravityScale = 0;
	movement->DefaultLandMovementMode = EMovementMode::MOVE_Flying;
	movement->MaxFlySpeed = 185.0;
	movement->BrakingDecelerationFlying = 100000000.0;

	camera = CreateDefaultSubobject<UCameraComponent>(TEXT("player camera"));
	camera->SetProjectionMode(ECameraProjectionMode::Orthographic);
	camera->SetOrthoWidth(750.0);
	camera->SetupAttachment(root);
	camera->SetRelativeRotation(camera_rot);
	camera->SetRelativeLocation(camera_location);
}

void Aoverworld_player_char_c::SetupPlayerInputComponent(UInputComponent* player_input_component)
{
	Super::SetupPlayerInputComponent(player_input_component);

	// Set up "movement" bindings.
	player_input_component->BindAxis("MoveUp", this, &Aoverworld_player_char_c::moveUp);
	player_input_component->BindAxis("MoveRight", this, &Aoverworld_player_char_c::moveRight);
}

void Aoverworld_player_char_c::Tick(float delta)
{
	Super::Tick(delta);
	is_playing = true;
	setFlipbook();
	moveCamera();
}

void Aoverworld_player_char_c::moveCamera()
{
	camera_loc = GetActorLocation();
	camera->SetWorldLocation(camera_loc);
}

bool Aoverworld_player_char_c::checkForDirectionBlockage(TSet<Edirection> dir)
{
	TSet<Edirection> in = dir.Intersect(lockedDirections);
	return (in.Num() == 0);
}

void Aoverworld_player_char_c::moveUp(float axis)
{
	bool can_move = false;
	FVector vect(0.0, 0.0, 1.0);
	if (axis > 0.0)
		can_move = checkForDirectionBlockage(topSet);
	else if (axis < 0.0)
		can_move = checkForDirectionBlockage(bottomSet);

	if (can_move)
		AddMovementInput(vect, (axis * movement_scale));
}

void Aoverworld_player_char_c::moveRight(float axis)
{
	bool can_move = false;
	FVector vect(1.0, 0, 0);
	if (axis > 0.0)
		can_move = checkForDirectionBlockage(rightSet);
	else if (axis < 0.0)
		can_move = checkForDirectionBlockage(leftSet);

	if (can_move)
		AddMovementInput(vect, axis * movement_scale);
}

In C++ you have to bind input actions/axis to functions. Start by overriding SetupPlayerInputComponent in your character subclass, and bind the axis like this :

void Aoverworld_player_char_c::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
    Super::SetupPlayerInputComponent(PlayerInputComponent);

    PlayerInputComponent->BindAxis("MoveUp", this, &Aoverworld_player_char_c::moveUp);
}

I already did this. I didn’t post all my code and forgot to mention it. I will update the question now.
