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"

Garbage collection: freezes

I have UMG widget with a lot of other widgets inside. Sometimes I'm creating it and after that, when garbage collection happening, game freezing. Right on the tick by every minute of a game.

I wounder: why garbage collecting actually freezing game? I thought it's something that works in background. Why all thread should wait while garbage will be collected?

Hello Alanir,

I was unable to reproduce this issue on my end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. What version of the engine are you using?

  2. Can you reproduce this in a clean project?

  3. If so, can you please provide a detailed list of steps to reproduce this issue?

  4. Can you tell me at what points exactly your game is freezing?

  5. Do you have any loops inside your widgets?

Hi Rudy,

Sorry, I didn't mentioned that I'm not only creating but removing widget too. It have a lot of inner widgets. And everyone have a pointer to main UserWidget and parents. Maybe it's about some sort of cycle-reference?
