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"

Sorry you are having this problem :( Could you give some more details on how you tried to create this var, if it had a particular name or type, what type of Blueprint you were in etc? Is this easy to repro?

I tried redoing the Door Blueprint tutorial following the steps.

Just happened again.

This time. I created a variable. Throw it in. used it.. saved( I swear I did )... realize no changes happened in-game. Then I go back to the blueprint. Changes are gone. Re-created the same variable with the same name. And then it happened. I did notice that right before it happened, when I click new variable button, It didn't ask me what type, it skipped and directly created the variable ( supposedly with no type ). At this point, selecting the variable shows empty property, but editor is still usable , until I decided to click around and the error pop out. I noticed that the var property seems to be showing up blank ( check the screenshot ) when this is about to happen.

In all 3 instances, it happened in Event Graph of blueprint object. alt text

Irony of the Irony. When I re-opened the editor. The changes were back on.

Did you have Blueprints with the same name in different locations? We fixed a bug related to that recently that may be what you were seeing.

avatar image ue4-archive ♦♦ STAFF Mar 11 '14 at 03:18 AM

Just checked.. nope. no blueprint of the same name

We have fixed several issues with variables shadowing inherited variables etc for the next beta. When it comes out, please let us know if you are still seeing this issue!
