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"

Editor crashes when you add a interface to a widget, that contains a function which has the same name as one of the target widget variables.

Version: 4.17.2

Platform Windows 10 x64

Description: If you add a BP interface to a BP widget, that contains a function which has the same name as one of the widget's variables. Then the editor will crash once you click on compile, without Warning.

Repro Steps: - Create a blank project - Create widget with a variable called "Test". - Create a blueprint interface with a function called "Test". - Add the interface to the widget and click compile.

Partial crash output:
