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"

TScriptInterface: GetObject or GetObjectRef?

I've been working with TScriptInterface quite a bit in some of my gameplay classes, and I have a couple of questions about GetObject() and GetObjectRef().

As far as I can tell, GetObject() is actually a macro to a function GetObjectW(), but the documentation for FScript interface only mentions GetObject and GetObjectRef. They both have the same description, but GetObject returns a pointer to a UObject whereas GetObjectRef returns a reference to a pointer to a UObject.

I understand where a reference might be preferable to a pointer, but isn't it possible to simply grab the address to the pointer and bypass the reference returned by GetObjectRef entirely? If so, when might it be preferable to use GetObjectRef over GetObject?

Which of the two is considedered better practice to use in general? What are the use cases for each? Are there any specific differences between the two that I should watch out for (besides the return type)?
