[New Wiki] Memory Management, Count References to Any Object, and Know Who is Referring!

Development Programming & Scripting C++

Dear Community,

I’ve just released a new wiki that shows you how you can count references to any AActor/UObject yourself!

You can also get an Object list of exactly who is referring to your UObject!

The code is quite simple, and I am using built-in runtime engine tools.

Garbage Collection ~ Count References to Any Object

Enjoy!

Sample output:



TArray<UObject*> Referencers;
 
GetObjReferenceCount(this,&Referencers);
 
for(UObject* Each : Referencers)
{
	if(Each)
	{
		UE_LOG(YourLog,Warning,TEXT("%s"), *Each->GetName());
	}
}

You are the best!

Thanks Rama, this should come in handy!

I noticed the return value in your example should probably be “ReferredToObjects.Num()” instead of the array pointer.

I changed the name in the code at one point and must have not added that, but it is correct now on the wiki, so all is well :slight_smile:

I hope you are having fun today!

Hee hee!

:heart:

Thanks again, Rama! This is very useful information.

hey, would it be possible to get an update of this code, with the wiki being shut down and all that?
im getting some really odd issues with GC and something like this would be extremely helpful for telling me what references arnt being resolved.
