示例#1

文件： Projectile.cpp 项目： vsharres/ProjetoRogue

void AProjectile::SpawnShootFX(const FVector& location, const FRotator& rotator, USceneComponent* component, FName name)
{
	FRandomStream Stream; //random stream

	FRotator rotTemp = rotator;

	rotTemp = FRotator(rotTemp.Pitch, rotTemp.Yaw, Stream.FRandRange(-180, 180)); //randomly rotate the effect

	//spawn shooting sound FX
	UGameplayStatics::SpawnSoundAttached(ShootFX.ShootSound, component, name);
