按键事件触发播放翻滚蒙太奇，调整姿态，是蹲伏还是站立。如果是站立需要蹲下再翻再起来

void ACwlAlsCharacterBase::OnRoll()
{
    GetMyAnimInstance()->Montage_Play(GetRollMontage(), 1.13f);

    if (GetCurStance() == ECwlAlsStance::Standing)
    {
        DesiredStance = ECwlAlsStance::Standing;
    }
    else if (GetCurStance() == ECwlAlsStance::Crouch)
    {
        DesiredStance = ECwlAlsStance::Crouch;
    }
}

翻滚动作的动画蒙太奇添加动画通知

void UCwlAlsNotifyStateMovementAction::NotifyBegin(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float TotalDuration)
{
    Super::NotifyBegin(MeshComp, Animation, TotalDuration);
    ACwlAlsCharacterBase* BaseCharacter = Cast<ACwlAlsCharacterBase>(MeshComp->GetOwner());
    if (BaseCharacter)
    {
        BaseCharacter->SetMovementAction(MovementAction);
    }
}

void UCwlAlsNotifyStateMovementAction::NotifyEnd(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation)
{
    Super::NotifyEnd(MeshComp, Animation);

    ACwlAlsCharacterBase* BaseCharacter = Cast<ACwlAlsCharacterBase>(MeshComp->GetOwner());
    if (BaseCharacter && BaseCharacter->GetCurMovementAction() == MovementAction)
    {
        BaseCharacter->SetMovementAction(ECwlAlsMovementAction::None);
    }
}

在动画通知的开始和结束set movement action

注意这两个地方有个进入事件 stop transition
同时补充逻辑

void UCwlAlsCharacterAnimInstance::StopTransition()
{
    StopSlotAnimation(0.2, GName_Ground_Slot);
    StopSlotAnimation(0.2, TEXT("(N) Turn/Rotate"));
    StopSlotAnimation(0.2, TEXT("(CLF) Turn/Rotate"));
}

这里加一个事件
