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"

AIperception causing Crash 4.14.3

Attached Log: My Project Log

I tried troubleshooting the Bug whenever I run the project, I see this alt text

As far as I can understand, it seems to be crashing due to the PlayerShip Blueprint, but it seems to be even more, because right after i removed the blueprint from the project, it detected the other blueprints who has AIperceptions, I tried fixing the stuff but it seems to be whenever i paste the previous save of those blueprints back to the project Content, it automatically crashes... this 3 Blueprints are worth 2-3 Working days of Scripting and this would be a huge setback if I cant retrieve this back... I need help please :(

Hey TheGreenCoder,

The crash listed in the thread you've linked to should have been fixed in 4.14, but out of curiosity could you try upgrading a copy of your project to 4.15 to see if the same crash occurs there as well?

If not, I'd appreciate it if we can work towards isolating the issue and reproducing it in a clean project so that we are able to reopen the ticket if need be.

I already updated unreal to 4.15 and went on a different way (seperating the two AI's) I'll be posting a way to reproduce the problem sooner or later.
