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"

Cannot package project due to use of a Factory

I use a custom factory in my project to allow easy creation of custom assets in the editor. When I try to package my project, I get an error saying "Cannot open include file: 'Factory.generated.h': No such file or directory".

My build output is here in case anybody wants to see it: http://pastebin.com/raw/iJhc7CtG

I understand Factories are really only useful when developing in the editor, is there some way to conditionally exclude them from the build process when packaging?

Are factories something that should be stopping the packaging process in the first place?

This is a much simpler question, could I at least get an answer to this?

UFactory is declared at:

Module: UnrealEd

Header: Editor/UnrealEd/Classes/Factories/Factory.h

You cannot package a game shipping Editor modules. If you want to use factories, you must create a Module with IMPLEMENT_MODULE() macro and create your factories in there; making sure that module will NOT be loaded by GAME modules. This is why your packaging fails, because you implement references to classes that are Editor only.

To create an Editor Module for your game project, look at a guide here: https://wiki.unrealengine.com/Creating_an_Editor_Module

I had a similar problem with a *.generated.h not being found/built. Ended up deleting the "./Intermediate/Build" folder of the project to fix it. The next build time was a bit of a bear, but it fixed the problem for me. Wasn't related to a factory class though.

If that doesn't work, I think I also greped for files under "./Intermediate" containing references to the offending header and deleted some those as well.

This did not fix the issue. Thanks though.
