Bug: "Any Key" event strange compile

Development Programming & Scripting Blueprint

Hello, I added this code on my Character for pressed keys tracking

And after I put “key get display name” my blueprint compiles successfully but compile sign never goes to “Good to go” anymore and stays “dirty, needs to recompile” even tho everything works just fine.

I tried this event on empty Character and sign goes green. Can you help me to solve this problem? If needed I can send project.

Maybe this bug not even connected to “Key Get Display Name” node. Someone had same problem?

  1. As I said I tried it in same project on new Character blueprint and it compiles fine and sign goes “Goodtogo”
  2. Not really, it just this event on screenshot that makes button stays “dirty” though blueprint compiles successful. Not really event but “get key display name” node. If I make (Any key → Print string) without anything sign goes “GoodToGo”
  3. My character pretty heavy blueprinted. Better if I send whole project I guess but it on 4.12.4

Hello Xukapy,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide any additional screen shots of blueprints/settings that may be need for reproducing this issue?

If you would like to provide your project you can do so by providing a link to a zipped down version of your project via dropbox or google drive.

Thanks, please change steps to reproduce a little bit

7 Notice that the blueprint will no longer compile

Blueprint IS compiling, its just the sign that stays “dirty”

Experiencing this now in 4.15 with Key is Gamepad within my controller BP. Oddly, creating a new controller BP and doing it there works fine. Also works in my player BP. So it seems to have happened within a particular BP. I am very early in the project, so there’s not a ton of content in it. It also has been compiling just fine otherwise. I can migrate everything over to a new BP, but I’m guessing you guys might wanna take a look.

UPDATE: So I was able to duplicate the BP and insert the Key is Gamepad node and it worked. Extra weird.

UPDATE: It ended up happening again anyway, even after compiling with that node and showing that it was compiled. Now it always shows dirty for compile status. It still works; it’s just showing the wrong icon for dirty I guess? It behaves as if it is compiled.

So it seems the bug is still around, but more of an aesthetic issue than a dev breaker.
