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"

EQS Crashes Editor

Hi! I decided that I wanted to start using EQS for my project but I can't seem to get it to work.

Here's what I do:

1) create Environment Query

2) Create Testing Pawn

3) Create Context Blueprint

Whenever I make changes to the context, the editor crashes but when I reopen the editor the context is set and the query DO generate from that actor/location.

It's very frustrating.

Product Version: UE 4.18

I haven't been able to repro a crash with the steps above. Could you send me your crash logs and maybe a sample project where the crash happens?

Hello, sorry for the late post but I want to say that I'm running through the exact same issue. The editor doesn't crash right after having made changes to the context but when you move the testing pawn after recompiling the context. Even if no changes were made to the context, just recompiling it causes a crash when moving the testing pawn again. I was on 4.19 but I have the same issue on 4.20.2 I don't think I had this issue on the previous versions (4.17 and 4.18)

I attach here a simple blank project with a few assets and a map where the bug happen. You'll just have to reproduce these steps to make the editor crash :

1) open "EQS_Context"

2) Unplug and replug something, no significant changes need to be made

3) Recompile "EQS_Context"

4) Try Moving :EQS_TestPawn" In the world : Editor crashes.

PS : I noticed that you don't even need have to recompile the EQS_Context to make it crash, just change the name of "EQS_TestActor" and try to move the EQS_TestPawn and it'll crash. this actor is actually called in the Context to get its location.

I really hope this help to fix the bug because it's such a very good feature that is almost wasted because of it

Hi, I've filled the submission form but didn't have a confirmation that it's been submitted. Can you tell me if it's okay?

Has this been resolved? I have a minimal project re-producing the problem. Wondering if there's a workaround

Not yet apparently. I've submitted a bug report bug didn't have the confirmation of the submission. I hope it had been taken in consideration because the form is quite long to fill.
