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"

How to help debug a frozen UE4 Editor (c++ plugin)


A customer is having the Editor frozen when clicking on a SButton on a Source Control plugin I made. It's a C++ plugin, in development build. I am unable to reproduce it.

In this frozen state, Unreal Engine is using 100% of one cpu core, the Log window is not clickable, and and last logs are not dump to the Log file.

Any tool to pinpoint this? Is there a way to get and understanding of what the Editor is doing from the outside ?

Seems much more difficult to debug than a "proper crash":

  • => Is there a way to crash the Editor from outside to get a proper stack?

Also, any common culprit to look at for such a freeze with a Slate UI? Some problems with delegates?



edit: I will try using Process Explorer to get a stack of a running process
