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"

Persistent levels not unloading with Open Level node.

here is the log I'm having a crash caused by my persistent levels not unloading when I leave them. When I go to start that level again its already loaded and causes a bug with one of my plugins that results in a crash. How do I fix this?

Do you have any screenshots or logs of the crash? Without knowing what the crash is it could be one of many things? Also, how are you current levels set up and do you do any streaming or just use the OpenLevel node?

The crash is caused by a bug with the level loading and a plugin we use. We've debugged the crash for the last 2 weeks and we know it is caused by the level not being unloaded when we try to enter it again.

We use Open Level nodes every level is persistent.

that still doesnt tell us much about your project, code, and the issue at hand. provide more details like crash reports, logs, screenshots, and what plugins your using.
