  if (HitSound)
  {
  UGameplayStatics::PlaySoundAtLocation(this, HitSound,SweepResult.Location);
  }
  

• PlaySound2D()

  UGameplayStatics::PlaySound2D(GetWorld(), HitSound)
  

• 其他

  • SpawnSound2D() 返回 UAudioComponent*
  • CreateSound2D() 返回 UAudioComponent*
  • SpawnSoundAtLocation() 返回 UAudioComponent*
  • SpawnSoundAttached() 返回 UAudioComponent*

播放特效

• SpawnEmitterAtLocation() 返回 UParticleSystemComponent*

  FString exploreParticlePath = TEXT("ParticleSystem'/Game/InfinityBladeEffects/Effects/FX_Monsters/FX_Monster_Chicken/P_Proj_Chicken_Imp_Explo_01.P_Proj_Chicken_Imp_Explo_01'");
