Why I get this error?

Hi Epic Odino,

The second line in your output log Ensure condition failed: InvocationList[ CurFunctionIndex ] != InDelegate is identical to this post: Handled error Ensure condition failed InvocationList[ CurFunctionIndex ] != InDelegate - C++ - Epic Developer Community Forums

Try taking a quick look at this post to see if you are having the same issue and if the solution listed helps. If not just let me know!

for your response, I’ve found the problem. This happens when I spawn an actor on begin play of another actor void ASpawnerVolume::BeginPlay() { Super::BeginPlay(); if (ROLE_Authority - Pastebin.com Why this cause a problem?

4

I don’t see anything that would cause a freeze. If enemy class is NULL this may cause issues I would check if Enemy Class is valid and if not Log an error.

if (ROLE_Authority == Role) 
{
if( EnemyClass )
{ 
GetWorld( )->SpawnActor(EnemyClass);
}
else
{
UE_LOG( LogTemp, Error, TEXT("Enemy class doesnt exist!" );
}
}

Also check to make sure your delegates are using unique functions.

Oh, Right… The problem is the spawned actor.

On AEnemy I’ve this BeginPlay http://pastebin.com/8PPQ6PmY where AddDynamic cause the problem. So AddDynamic can be used only on the constructor?

I talked with a co-worker and this is what he recommended. On the constructor.

 AEnemy::AEnemy() 
{
SensorSphereComponent = CreateDefaultSubobject<USphereComponent>( TEXT("Collider") );
SensorSphereComponent->OnComponentBeginOverlap.AddDynamic(this, &AEnemy::OnLocalBeginOverlap);
SensorSphereComponent->OnComponentEndOverlap.AddDynamic(this, &AEnemy::OnLocalEndOverlap);
}

At this point it has been determined not to be a bug with the engine. You can check out our documentation and content examples or post in the C++ section of AnswerHub to get assistance with this questions from our commuity!
