I’m using the delegate [OnMontageEnded](https://dev.epicgames.com/documentation/en-us/unreal-engine/API/Runtime/Engine/Animation/UAnimInstance?application_version=5.5) of the `UAnimInstance` to detect when an attack montage has been completed as such:

```auto
void AMyCharacter::Attack(const FInputActionValue &Value) {

    if(IsAttacking)
        return;

    IsAttacking = true;

    UAnimInstance* AnimInstance = GetMesh()->GetAnimInstance();
    if(AnimInstance){
        AnimInstance->Montage_Play(AttackMontage);
        AnimInstance->OnMontageEnded.AddDynamic(this, &AMyCharacter::AttackEnd);
    }
}

void AMyCharacter::AttackEnd(UAnimMontage* Montage, bool Interrupted){

    UAnimInstance* AnimInstance = GetMesh()->GetAnimInstance();
    AnimInstance->OnMontageEnded.RemoveDynamic(this, &AMyCharacter::AttackEnd);
    IsAttacking = false;
}

```

I’ve noticed most tutorials online use notifies for this instead, Can I run into any problems doing it this way?
