Question regarding removing a struct from TArray

[JackxBlack]

Hello. I’m trying to make a simple Container Component, that holds a TArray of items. The items are a struct - FItemInstance. There’s a function for removing items, that calls Remove on the TArray with a const & to an item (assuming the array contains it). However, using the Remove throws a whole bunch of errors, with (I think) most relevant being:

BRWContainerComponent.cpp(46): note: see reference to function template instantiation 'int TArray<FItemInstance,FDefaultAllocator>::Remove(const FItemInstance &)' being compiled

Here’s the TArray and function from .h:

UPROPERTY(VisibleAnywhere)
	TArray<FItemInstance> StoredItems;

UFUNCTION(BlueprintCallable)
	void RemoveItem(const FItemInstance& ItemInstance);

and here’s the function in .cpp:

void UBRWContainerComponent::RemoveItem(const FItemInstance& ItemInstance)
{
	if (StoredItems.Contains(ItemInstance))
	{		
		StoredItems.Remove(ItemInstance);
	}
}

I’ve tried removing both UPROPERTY() and UFUNCTION() and it didn’t help. Any ideas what I’m doing wrong? My VS (with VA) doesn’t even highlight any errors…

I also don’t understand why only Remove() is wrong, since Contains() has the same definition and is used in the same way. EDIT: nvm it does. If I comment out Remove it breaks on Contains…

Thx to help from elsewhere I know it’s caused by my struct not having == operator defined. I would probably use UObject here instead of a struct (though unique id property for the struct was also propsed and it would work too)
