I was playing around with Event dispatchers and Blueprint Interfaces to see how I could pass variables between my HUD and other Blueprints. I deleted the interface, which caused some reference issues and lots of crashing (I won’t be doing that again). Eventually (I think) I sorted those out.
However, I have an Event Dispatcher in my Blueprint that I can’t delete, and a warning appearing in the Compiler results; “No SignatureFunction in MulticastDelegateProperty ‘%s’”. I can’t work out why this message is appearing, nor why I’m unable delete the Event Dispatcher (I’m not trying to call it or reference it in any way in any of my Blueprints). If I try double clicking on this phantom event dispatcher, no tab is opened; I don’t think it actually ‘exists’.
Whilst this isn’t causing a compiler error (and thus isn’t game-breaking) I hate developing with a big yellow warning triangle appearing every time I compile!
I got the same problem sa well. I just can’t delete that dispather and it keep gives me exactly the same warning as you meet. I am going to delete the blueprint and remake one.
What version of the editor are you running? Does this occur in a clean project with no additional content? When th ewarning appears, does it have any text that you can click? For intance, can you click event dispatcher in the warning and it direct you to the location of the error? You may be able to get rid of it that way. Thank you!
I am running 4.3. It happends in a project with mouse event template (I deleted some content and added my own content). I just created a event dispatcher and played with it then try to delete it. But the delete option is turning grey which means not available and I can’t delete it by press “delete” key as well. And I check my blue prints, I didn’t use this dispatcher any where, but when I compile this warning would pop up. I can’t remember if the warning gives me a clickable text. At last I deleted the blueprint which hold the event dispatcher (And replaced it with another) then the warning were gone.
Unfortunately I have been unable to reproduce this effect. If you have an asset that is producing this effect and are comfortable sharing it, I would be more than happy to have a look at it and see what is occurring.
I understand completely. If this comes up again please feel free to comment with this information. I will mark this question as answered for tracking purposes.
