解决UE4开发播放动画有一帧Tpose

实现代码

void SequenceEventManager::PlayAnimMontage(class USkeletalMeshComponent* InMeshComponent, class UAnimMontage* AnimMontage, float InPlayRate /*= 1.f*/, FName StartSectionName /*= NAME_None*/)
{
    if (IsValid(InMeshComponent) && IsValid(AnimMontage))
    {
        if (UAnimInstance* AnimInstance = InMeshComponent->GetAnimInstance())
        {
            float const Duration = AnimInstance->Montage_Play(AnimMontage, InPlayRate);
            InMeshComponent->TickAnimation(0.f, false);
            InMeshComponent->RefreshBoneTransforms();
            if (Duration > 0.f)
            {
                // Start at a given Section.
                if (StartSectionName != NAME_None)
                {
                    AnimInstance->Montage_JumpToSection(StartSectionName, AnimMontage);
                }
            }
        }
    }
}

动画是Tick驱动的，调用播放动画有概率出现还没走到下一Tick。直接调用一下Tick里面的驱动函数 InMeshComponent->TickAnimation(0.f, false); InMeshComponent->RefreshBoneTransforms();
