Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

What does this syntax do in C++?

Taken from: https://docs.unrealengine.com/latest/INT/Gameplay/DataDriven/

     : XPtoLvl(0)
     , AdditionalHP(0)

This is in the public area of a struct. I don't seem to remember this type of syntax from C++, can anyone explain each line?

Product Version: UE 4.10

That's the constructor for the struct/class. In this particular case the default constructor, no parameters that is, is empty since no code exists between the opening/closing brases { . . . }

During the construction phase the two members, XPtoLvl and AdditionalHP, which are int32, are set to 0.
