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"

Undeletable event dispatcher created

Hi,

in my umg blueprint, there is one event dispatcher that is invisible from the list and one that I can't delete or rename. Probably happened because the total name got too long or because the first one contains a period, don't know. Now if I compile my blueprint, I get a warning that I want to get rid of:

 Warning No delegate property found for  Dispatch_BTN_Select.Atp
 Warning No SignatureFunction in MulticastDelegateProperty 'Dispatch_BTN_Select_Atp'
 Info Fast Template Successfully Created.

Could I edit the uasset file in a text editor, so I could delete both dispatchers from the blueprint editor - or will my file get corrupted this way?

Steps to reproduce:

  1. Create widget blueprint

  2. Create event dispatcher "NewEventDispatcher_abcdefg.hi"

  3. Drag event dispatcher in editor, select 'Call'

  4. Rename event dispatcher to "NewEventDispatcher_abcdefg_hi"

  5. Refresh dispatcher node - name won't change to underscore version

  6. Congrats, now you can't delete or rename your dispatcher from the list

Product Version: UE 4.16

Seeing the same bug in 4.21.2, and ended up having to copy-paste across to a new UMD blueprint, and redo all the connections in the level blueprint. What a huge pain.

Thank you! Even after the bug is getting fixed, the faulty delegates would stay in my blueprint. So what is your opinion on editing the uasset file to get rid of the problem, bad idea?

I would suggest using a backup file for the asset from before the Event Dispatcher was added. I have provided a link to the default location of the back up files below.

Default directory (C:\Users\YourUserName\Documents\Unreal Projects\YourProjectName\Saved\Backup)

I was able to repro this issue in 4.20. I created an event dispatcher in a BP called MLTotemRightOff and added a call and bind in the BP. I then renamed the event dispatcher to SimpleTotemRIghtOff and deleted the call and bind functions to the event dispatcher. Now when i compile the BP, I get a warning that "No delegate property found for MLTotemRightOff

I duplicated the BP and still get the same error. I cant find a way to resolve this

Why is it marked as "fixed" in the bugtracker? It still happens in 4.20

This should not be marked as fixed, I'm still seeing it in 4.22.2.
