Hi, I wonder if there are any plans to get these in Blueprint. I found for example, that TSet and TMap did get added in 4.15.
I would really like to have these Map Types available in Blueprint to avoid the need to go for C++ just for some small part of code…
Maybe there are some good reasons for not having these in BP. But the SortedMap for example can even be faster than TMap for low element counts.
I would like to see these in blueprints as well, mostly the TMultMap (there is a work around of having a Struct but it isn’t great)
for the TSortedMap they probably feel that “TMap already has sort, so just call it” on the speed of TSortedMap, for lookup and iterating over it should be faster, but for insertion even without collisions it would still have a speed drawback as at the very least every insertion would call sort(), and based on the potential random order of Remove() it should call sort on that too.
for the TMultiMap they might think it troubling to have to work with a 2D data structure (a TMultiMap<T1, T2> is a TMap<T1, TArray<T2>>) in the Details window either on the implementation side where it should be usable or on the paradigm of “don’t want to confuse non-programmers” (this has some merit at times, and can be more then a bit condescending at others).
the best work around to a TMultMap<T1, T2> is to TMap<T1, T3> where T3 is a struct that holds an array of T2, but this feels clunky on all levels, and would probably be the same details window result as any reasonable implantation of TMultiMap.
