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"

I started to get this odd error in my game every now and then when I randomly open the project on times. Sometimes it'd just work fine, sometimes I'll get the crash. My solution at the moment is not optimal, a rebuild all fixes it but it consumes alot of time.

First it started happening with my interfaces, then I removed those and remade them under a different name, now it's happening with other classes.

I'm working on a complete renew of the project on a different branch of the project and I removed all files before-hand so it shouldn't know about any other files.

Any idea how to find what causes this? :o

"I'm working on a complete renew of the project on a different branch of the project and I removed all files before-hand so it shouldn't know about any other files."

can you explain how you did this? As most likely this is the carprit and mess preferences in assets. it's C++ project right?

Yeah! I removed everything except for the .git folder. Its indeed a C++ project. I just created a new branch with an entire new "project" but it has the same name and everything. But none of the files from the old project are around. I just migrated them by downloading the source assets from gitlab and put them back in their place, compiles were working aswell.
