231 insect: insect enemy type

创建dead动画资源

往insect head上添加socket

创建攻击root motion动画。motion warping需要与root motion合作使用

为buff_blue创建物理资产

设置simulate physic使sinsect死亡后能落到地板上而不是漂浮在空中，要将die函数设置为

----------BaseCharacter.h----------
	//BlueprintNativeEvent不能和virtual关键字公用，并且在实现.cpp时要加后缀_implement以及子类继承重写时要加上
	UFUNCTION(BlueprintNativeEvent)
	void Die();

------------BaseCharacter.cpp-----------
void ABaseCharacter::GetHit_Implementation(const FVector& ImpactPoint, AActor* Hitter)
{
	//DRAW_SPHERE_COLOR(ImpactPoint,FColor::Blue);
	if (IsAlive() && Hitter)
	{
		DirectionalHitReact(Hitter->GetActorLocation());
	}
	//需要调用die函数（蓝图中的event die),才能走蓝图逻辑,而不是c++中的die_implementation
	//You need to call the `Die` function (the `Event Die` in the Blueprint) to execute the Blueprint logic,
	// rather than calling the `Die_Implementation` in the C++ code.
	else Die();

	PlayHitSound(ImpactPoint);
	SpawnHitParticles(ImpactPoint);
}
------------Enemy.h------------
	/** <ABaseCharacter> **/
	virtual void Die_Implementation() override;

----------Enemy.cpp-----------
void AEnemy::Die_Implementation()
{
	Super::Die_Implementation();
	EnemyState = EEnemyState::EES_Dead;
	
	//不加clear的话，角色死亡之后会像僵尸一样原地又立起来
	ClearAttackTimer();
	HideHealthBar();
	//不加这一个的话，在角色销毁之前，胶囊体呆在原地会阻碍echo的前进
	DisableCapsule();
	SetLifeSpan(DeathLifeSpan);
	//不加这一个的话，角色死亡之后可能会旋转
	GetCharacterMovement()->bOrientRotationToMovement = false;
	//如果不加这个设置，角色死亡之后还没销毁的这一阶段，武器仍能对echo造成伤害
	SetWeaponCollisionEnabled(ECollisionEnabled::NoCollision);
	SpawnSoul();
}
