Problems with collisions

[Eduardo_Ricciarelli]

Hi, I´m having problems with the NPC that doesn´t shoot me correctly:

As you can see shoot off set and doesn´t do to me any damage. I have the same problem as the player that I don´t hit the NPC and don´t get any log message.

Advancing in the course I realize that doens´t affect the health bar at all, so the character isn´t recieving any damage.

What is happening? Thanks

Have you logged out the names of what the line trace is hitting?

[Eduardo_Ricciarelli]

Yes I follow the Debug line in the class of ray tracing and haven´t any problem.

[DanM]

Perhaps you may have misunderstood? I was asking how have you tried debugging your issue so far.

[Eduardo_Ricciarelli]

I try with the debug line that we saw in the class and also finishing the course waiting to see if that will help solving the problem.

[DanM]

What I’m suggesting is you log out the names of what the line trace hits.

bool bSuccess = GetWorld()->LineTraceSingleByChannel(Hit, Location, End, ECollisionChannel::ECC_GameTraceChannel1, Params);
if (bSuccess)
{
    UE_LOG(LogTemp, Warning, TEXT("Hit %s"), *AActor::GetDebugName(Hit.GetActor()))

Hi, with that debug line the player and NPC are hit, but doesn´t suffer damage:

thanks for the help, what else could be wrong?

[DanM]

Well my next point of action would be logging just before calling take damage

FPointDamageEvent DamageEvent(Damage, Hit, ShotDirection, nullptr);

UE_LOG(LogTemp, Warning, TEXT("%s Hit %s"), *GetName(), *HitActor->GetName())
HitActor->TakeDamage(Damage, DamageEvent, OwnerController, this);

[Eduardo_Ricciarelli]

I put it here:

Ando also this see I have this other UE_LOG:

And none of them gime me information in the output log.

[DanM]

Odd, and then if you move that first log to before the if?

[Eduardo_Ricciarelli]

I can´t neither before that if or the first one:

[DanM]

I meant after the declaration of HitActor

[Eduardo_Ricciarelli]

It gives me the same log as before.

[DanM]

That’s weird, did you use AActor::GetDebugName before? That difference is that it will print Null if the actor is nullptr. So I’m wondering why it’s somehow both null and not null.

[Eduardo_Ricciarelli]

No, first time I listen of that function. If you told me how to used it I can give it a try. Thanks for your help by the way

[DanM]

I already posted it
