setTimer为什么用了没有效果

void AMapleStoryCharacter::Sword()
{
Swording = true;
GetWorldTimerManager().SetTimer(TimerHandle, this, &AMapleStoryCharacter::AtkSword, 2.0f, true);
Swording = false;
}

void AMapleStoryCharacter::AtkSword()
{
GetSprite()->SetFlipbook(AttackAnimation);
//GetWorld()->GetTimerManager().ClearTimer(TimerHandle);
}

为什么这样子写按j的时候角色并没有攻击
GetWorldTimerManager().SetTimer(TimerHandle, this, &AMapleStoryCharacter::AtkSword, 2.0f, true); 这句话我在tick里面放过，在beginplay里面放过，可是好像都没有效果
我是想让他攻击的时候delay个几秒，让攻击动画放完

P.S：我做的是一个2d游戏
