The springarm does not move

[Kimbab]

I want to move the springarm to the top to raise the field of view. But the springarm won’t move.

void ATank::SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) {
    //상위 버전 호출
    Super::SetupPlayerInputComponent(PlayerInputComponent);

    PlayerInputComponent->BindAxis(TEXT("MoveForward"), this, &ATank::Move);

}

void ATank::Move(float Value){
    UE_LOG(LogTemp,Warning,TEXT("Value : %f"),Value);

};

And in the lecture, when I declared SpringArm and Camera, I didn’t make a Type Declaration before. But because I didn’t make a Type Declaration, I had a problem and made a voluntary declaration, but why didn’t I declare it in the lecture?

They have to be declared in the header. This is required so that you can set the UPROPERTY(VisibleAnywhere) so you can edit them.

[Kimbab]

Are you saying to do UPROPERTY (VisibleAnywhere) to move the springarm?

[beegeedee]

Yes, but also you have to add the Declaration in the header, not in the constructor. Look at the end of lecture code to see what I mean.

In the header Tank.h you have to have:

UPROPERTY(VisibleAnywhere)
USpringArmComponent* SpringArm;

UPROPERTY(VisibleAnywhere)
UCameraComponent* Camera;

in your ATank::ATank(), you still create them and attach them but you don’t declare them

You made a name mistake. I didn’t notice this. Thank you for your kind reply. It works properly.

[beegeedee]

Definitely possible. I typed from memory. The editor would have told me when I was entering something wrong.
