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"

HotReload is not active when Editor is open

Hi Community,

I´m kind of confused. I don´t get HotReload working when compiling in VS in one particular project. The UnrealEditor is open, the Build Configuration is set to "Development Editor", but when I hit compile, VS wants to write to the "UE4Editor-NAME.dll" and not to the ""UE4Editor-NAME-FUNNYNUMBER.dll". D

The Output:

 1>------ Build started: Project: UE4, Configuration: BuiltWithUnrealBuildTool Win32 ------
 2>------ Build started: Project: EscapeTheRoom, Configuration: Development_Editor x64 ------
 2>  Creating makefile for EscapeTheRoomEditor (no existing makefile)

 ========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

So these HotReload-DLL files are not created and I don´t understand why. When I open another 4.19.-Project HotReload works.

Do anybody know where the problem might be?

Cheers,

Simon

Ahh I got it to run:

If VS isn´t compiling with HotReload (UE4Editor is open), just compile in Unreal, and afterwards we can compile in VS.

Nice !
