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"

What does the Game Launcher do that is under the 'Experimental' section?

Today I found in the experimental section of the editor a feature called "game launcher".

How does it work? What will it do exactly?

On other engines launchers with the ability to update/patch the game are done manually by every developer... Talk about reinventing the wheel over and over again...

All game eventually require updates, how about developing once and for all one solution everyone can use? Perhaps a solution that works by storing the files on a web server that supports resume, then with some md5 or other voodoo the client downloads/resumes/repairs different/corrupted/missing files.

Hey bigzer,

The Game Launcher is another method for packaging your game. It's a part of the Unreal Frontend.

The option in the Experimental section enables the Game Launcher UI in the Editor, which you can then access via Window > Unreal Frontend. It is normally only available in the UFE, because it works for any project and not just the currently loaded project, and this can be confusing to new users. That's why it's currently in the Experimental section. If someone wants it available in the Editor, they can turn it on with that checkbox, but it's not enabled by default because conceptually it doesn't quite fit. Generally the recommended approach for launching games from the editor is PIE or Launch in the toolbar.

What you're looking for is something the developers are looking into and may eventually provide as part of the Unreal Launcher. The overlapping terminology can be confusing so all of these may go by different names or may not be available in the future.

Hope that clears things up!

Thank you Ben, it makes sense now. Perhaps calling this game executer or game starter could avoid confusion with the usual 'game launcher' everyone is used to see in games.

On a side note knowing that you guys are considering a game updater/launcher is a big hurrah! It looks like engine providers are scared to provide a solution out of the box for everyone which is weird really. Knowing in depth the data structure of games build with the engine allows good patching methods for small memory footprints so I'm pretty sure nobody could do something better than Epic on that matter.

How about adding this on the Trello ? :)
