You Cannot Set A Member Variable As A Pointer To A Delegate
Almost all the time, you want a reference to unreal engine delegates, not a copy. At this point you may have tried and attempted to do something like:
UPROPERTY()
FSomeDelegate* delegatePtr;
Or
FSomeDelegate& delegateRef;
This will not work and Visual Studio will have warned you even before building or as building errors. Specifically for the Pointer type, You may get the error:
cannot have an exposed pointer to this type.
and for the reference method , you may get a build error saying something along the lines of:
references must be initialized.
That is because in c++ a reference needs to be set at declaration.
The Workaround
A solution that often works is to get a pointer to the UObject* that contains the unreal engine delegate. The downside is you will need to go through this UObject* to access the delegate every time in code but it’s a small tradeoff. Here is an example of calling the Broadcast function through the UObject.
UObject->DelegateVariable.Broadcast()
