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"

My game has become crash happy after 4.12 update

I've been working on my game since UE 4.7 and every update has gone well except this one.

At first it would crash the game when launched on start up, this was resolved by adding a delay to the play sound node that I used to play music on start up. After that I made it to the main menu and the next series of crashes were provoked by a spawn 2D sound node. Again adding a delay stops it from crashing.

After that I can get my levels to load but something is still provoking a crash and I don't know what it is and the logs aren't giving me more info.

Strangely enough if I export it to my iphone it works perfectly and loads very quickly with out any hitches.

Does anyone know what is going on?

Product Version: UE 4.12

HI Archerx,

Entire project crashes like this can sometimes be a bit hard to track down. We are going to need some more information. Could you please post the Call Stack from the Crash Reporter popup window and make sure to submit it. Include your Epic ID or Machine ID.

Also post your Crash Logs.

Do you get the crash reporter window? If so, make sure to submit it please include the other info I mentioned above.

In the meantime, I'm looking into your logs.

1 answer: sort voted first

The crash report wasn't giving me much info because I did not install the debug symbols so I decided to uninstall UE4 and reinstall it with the symbols and my game ran without any issues.

Either I needed the debug symbols (they're 8gigs!) or something went wrong with the first installation/project copy.

I would consider this somewhat solved?

That's good to hear! If the crash is no longer happening then yeah, we can consider this resolved for now. I wasn't able to track down the exact cause with the logs alone.

If this issue pops up again, just post a comment here to reopen the post. In the meantime I will be keeping a eye out for any other reports of this issue.
