When trying to check the event instigator to make the hit enemy turn to the damage location, the game crashes. I am not sure why.
float ABM_EnemyPawn::TakeDamage(float DamageAmount, struct FDamageEvent const& DamageEvent, class AController* EventInstigator, AActor* DamageCauser)
{
Super::TakeDamage(DamageAmount, DamageEvent, EventInstigator, DamageCauser);
Health -= DamageAmount;
if (Health <= 0)
{
//...Die
PlayDeath();
bDead = true;
return DamageAmount; //Return modified damage
}
else
{
this->PlayAnimMontage(TakeDamageAnim, 1.0);
//Rotate to hit location
if (EventInstigator->GetOwner() != NULL) // Problem statements
{
FRotator HitRotation = FVector(EventInstigator->GetOwner()->GetActorLocation() - this->GetActorLocation()).Rotation();
HitRotation.Pitch = 0;
HitRotation.Roll = 0;
this->SetActorRotation(HitRotation);
}
this->GetMovementComponent()->StopMovementImmediately();
return DamageAmount; //Return modified damage
}
}
This is the crash log

The same exact thing happened when trying to get the enemies based actor to bounce off. I was forced to do a trace instead.
