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"

Property serialization vs Binary serialization

It seems like there are two different methods of serialization used in the engine:

  • Property serialization which is done automatically for non-transient properties and which is nice because it handles adding and removing properties well.

  • Custom serialization code implemented in Serialize() method override. This presumably provides more flexibility but requires messing with versioning every time something changes. I will refer to this as "Binary serialization".

Here are my questions:

  1. When it is preferable to use Binary serialization?

  2. My guess is that since Binary serialization uses less space it is preferable for cooked assets while property serialization is preferable during development when properties get added and removed. Is that correct?

  3. Sometimes in the engine code properties get serialized in Serialize() even though they are not transient. Is this by a mistake?
