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"

[Closed] Interface Events Not Showing in Menu

I have tested this on several different projects using v4.5 and the experimental editor functions are enabled. Disabling them made no change.

When I create a A blueprint that implements an interface containing function declarations with no output nodes, I am not able to find the event nodes that should be created in the host class even though I can access the functions themselves. This means even though I can call the functions I can't edit them. If I add a return value, I can call them and edit them, but I still can not generate a default event for them because it appears that one already exists that has already been created.

Obviously the event exists because it will not let me create an event with the same name.

This is the function created in the Interface BP

As you can see, I can call the function but no event exists

As a work around, I added a bool to the return values for each of the functions. I am still not able to create events(which seems like may have been a deprecated method of doing things), but at least I can edit the function graphs now.

Hey RAVaught,

Try disabling the experimental Use New Blueprint Menuing System. I checked this and it seems I cannot find the Event for an Interface Function either, even when searching for it by name. After disabling that feature, it appeared as expected when I searched for it.

The new system was put into 4.5 to help deal with some of the issues with the context menu, but it doesn't fix every issue and this appears to be one of those weird examples. I can confirm that this functions as expected in our internal build, and should work correctly in the next release. In the meantime, you may need to turn off this experimental feature now and again if a node does not appear when you expect it to.

Hope that helps!

I toggled off the experimental menu system and the function events still don't show up (see image). I also tried a full restart, with no joy. If this is fixed in the upcoming release, I will set it as resolved for now. Thanks for the quick reply.

Regards, Tony

Are you in 4.5.0 or 4.5.1?

avatar image RAVaught Nov 07 '14 at 09:38 PM

4.5.0 I won't be able to make the move to 4.5.1+ for at least another week.

Ah, okay. Let me know if this still occurs once you update and we'll look into it a little deeper.

I can verify this is still occurring in 4.5.1 for me, cannot access the events in a blueprint with the interface implemented, and without any returns UNLESS i disable the new bp menu system. pretty frustrating, as it hinders experimentation that was previously very solid and helpful. Love the system though, not having too much of a gripe :D

Nah, not too big of an issue unless you are new and don't know about it, or you have to keep switching back and forth to get Interface events and Cast To nodes.
