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"

Having to restart editor after c++ changes

I'm fairly new to programming C++ in UE4, and I'm running into some frustrating workflow issues.

I have the following line inside of a function

 GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Blue, TEXT("This is the log!"));

Whenever I change the text int the debug log message, build the code successfully, when I relaunch the PIE expecting to see the updated code, it instead shows what the text said pre-change. The only way I can get it to display correctly is by restarting the UE editor.

Am I missing something here?

Do you have any pluggin in your code ?

Anyway, try the folowing : Windows->Developer tools -> Modules Then find you game module and click the compile button.

I do have the same problem as you, but it linked to my pluggins and this solution works for me :)

Na, not currently using any Plugins, just a blank c++ project with my few code files in it.

To compile changes in C++, you either need to close the editor down, compile, and re-open the editor, or use Hot reload of the project.

In the editor, in the top bar, there should be a 'Compile' option, which will compile and reload your code.
