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"

Modifying UPROPERY value, making it persistent

I need to modify a UPROPERTY value within a component from C++ code (preferably from the component itself). The modified property must be serialized when the package is saved. I cannot find a suitable place to modify this property, it ends up in the UCSModifiedProperties list (read only in the editor and won't save). There's one single exception I found though. If I override PostEditImport I can modify the property value and it will be serialized, but PostEditImport is ONLY called if the actor is copy-pasted. I must be able to set the property value when actor dragged into the world.

Product Version: UE 4.9

I am confused. You are trying to modify the value from C++ in the editor, and you want to store the C++ modified value as the new default value? Or the C++ is trying to modify it at runtime?
