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"

".generated.h" file cannot be opened

When I try to use the JSON Utilities Library, I get fatal errors from "JsonObjectWrapper.generated.h" being unable to be read. This only impacts "JsonObjectWrapper.generated.h", however, no matter what I use within JSON Utilities, I get that error. I have consistently seen errors both across 4.21, and 4.22, and across multiple projects in both versions.

Product Version: UE 4.21

You need to do a little more than just regenerating VS project files. Close both the Unreal Editor and Visual Studio. Open your project directory and delete all these folders - .vs, Binaries, Intermediate, Saved [optional], and also YourGame.sln files. Make sure that the Config folder is there and that you do NOT accidentally delete it!

Next, right click on the YourGame.urpoject and select Generate Visual Studio project files. Open the .uproject file once it finishes regenerating. The Editor will prompt you with a missing .dll module again and will ask you to rebuild the solution. Click Yes and it will start rebuilding. It should now successfully compile if there are no bugs in your code. TellPopeyes

Hope this helps :-)
