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"

Project constantly crashing

Hi,

I have a project since the 4.14 version of Unreal. I have been porting it with no aparent issues but now it keeps crashing. I`m using source control and despite reverting to a previously stable version, the project keeps crashing.

I switched to ReadOnlyTargetRules (or smth) on the constructors, as pointed out by the compiler.

It happens on a new map, without using any of my assets (bp, controllers, game modes...) so I have no idea what could be the problem. It starts, but when I exit the game, it crashes. When I compile two times the project (via a bp) it crashes...

I debugged with visual studio to see where it was crashing but it didn`t help me, as each crash had different values on the variables, despite always being on the same place.

This is the crash report.

 Fatal error!

Thanks to the logs I fixed some warnings and errors I had on my BP. Yet it keeps crashing.

Ok, so I had a variable that referenced a type that no longer existed (a object type) and despite it not being used, it caused the project to crash.
