How to build A TMap with FString and TFunction?

So, I was experimenting a little bit with this idea and I came up with a solution that does what you expect.

When defining your map, do it like this:

TMap<FString, TFunction<void(USomeActorComponent*)>> StringFunctionMap;

In this way you are storing a pointer to a function whose first argument is a pointer to USomeActorComponent. You just need to remember that a member function is just a function where the first parameter is the this you can use inside the function.

You can create the map in the same way:

StringFunctionMap.Add(TEXT("FunctionA"), &USomeActorComponent::BlahBlah);

The only difference will be when you call this function:

StringFunctionMap["FunctionA"](this);

You just need to remember to pass the this.
