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 Load Project at all!

I created a loop with a break in my HUD script - I guess there was an error with how I set it up, but the editor closed right down completely and now I am unable to open this project at all. Everytime I try to load it, the editor just shuts down. I have a TONNE of work in there that I can't afford to lose! Is there anyway I can get my blueprints back? I tried importing the blueprints into another new project, and as soon as I go to open the blueprint in the editor, the editor shuts down again. ACK!!!! This goes for ANY blueprint that was in the project, including my character, game mode, state etc. I can't afford to lose all this hard earned work. What can I do??

This is what I get when I try to open the project from within VS2013

Ok so this was a blueprint that created this issue? You could also make sure your Launcher engine did not get corrupted and do a verify from the UE4 launcher to make sure all files are still intact.

It's not the launcher, because the launcher runs any other project fine sadly :( This is so frustrating...months of work nearly taken off my list because of it. I've done a complete reinstall/recompile of the editor and its no issue there. And yes, it was a blueprint that caused this issue.

I think I saw that you got around this on the forums, but in the future if you feel a specific blueprint is causing an editor crash and you can't open the project, go into your asset folders and remove the blueprint file from the folder. This should let you load your project.

Then, in some cases you can drop the blueprint back in the folder while the editor is open and fix your blueprint.

In other cases you may want to find the Autosave for that blueprint and drop it in the folder instead.

I also had an issue where a for each loop with a break basically corrupting my project in 4.4.3. I had to roll back a day of work because of it.
