[Solved] Gameinstance deconstructor called twice

Development Programming & Scripting C++

I need to have some things when the application is shutting down.

thougt the gameinstance would be a good place to put the code but found out in the log that the deconstructor gets called twice?

Why?

Anyone else have this?



//Deconstructor
UNitroGameInstance::~UNitroGameInstance()
{
UE_LOG(LogTemp,Warning, TEXT("First call"));
UE_LOG(LogTemp,Warning, TEXT("Second call"));
}

LOG:

Well i guess it´s monday morning :rolleyes:

Leaving this post but as solved.

For anyone else
the solution is simple :stuck_out_tongue:




virtual void Shutdown() override;

The destructor is run twice. Once for the instance of the class and once for the Class Default Object (CDO).

You can check for the CDO and return like so:

[FONT=Courier New]if (HasAnyFlags(RF_ClassDefaultObject))
{
return;
}
