While I was practicing a simple FPS example, I found that the ‘LookUp’ and ‘Jump’ function for the Character have no effect
What I did is:
1.inherit a class from character class
2. did these like below

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

	PlayerInputComponent->BindAxis("MoveForward", this, &ASCharacter::MoveForward);
	PlayerInputComponent->BindAxis("MoveRight", this, &ASCharacter::MoveRight);
	PlayerInputComponent->BindAxis("Turn", this, &APawn::AddControllerYawInput);
	PlayerInputComponent->BindAxis("LookUp", this, &APawn::AddControllerPitchInput);
	PlayerInputComponent->BindAction("Jump", IE_Pressed, this, &ACharacter::Jump);
}

3.bind axis and action like this:

Results:
The character can move and trun, but can’t jump and look up and down,which really confused me.

Is there anyone so kind to help me solve the problem?
