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"

[4.12.5] [bug] Splitting struct pin on custom event in widget shows error label when modifying widget's variables

When using a custom event in a widget that uses a struct as its input, if the pin was split to show the struct's variables an error will appear when a variable to the widget is added, removed or modified. This error message does not do anything and disappears when the widget blueprint is recompiled.

Steps to reproduce:

  1. Create a structure with variables in it.

  2. Make a User widget blueprint.

  3. In the graph add CustomEvent with the input being the structure.

  4. Split the structure pin.

  5. Add a new variable to the widget and see error.
