Spacebar for jump not working?

Development Programming & Scripting
1

I have no idea why this is happening but I can not get space bar to work as a input for game play.

Ive done two days worth of searching and come up with nothing.

  • I tryed unchecking Focusable on all of my UMG buttons and I still cannot jump with spacebar
  • I removed my HUD and UMG from the game with no change
  • I changed the input to N and it works as expected. Changed it back to spacebar and still does not work

Any help or ideas would be huge and save my head

Do you use set input mode nodes ?

yeah it is the jump preset from the third person templet

1 - I don’t know if it’s an UE4 bug
2 - Spacebar can be already attached to another input event.
3 - Can you try in a new PlayerController to test (example files are sometimes bugged)

just replaced the old controller with a blank new one and space bar still wont work for jump. I also search the whole project for the space bar input and the jump input and found nothing.
-edit: it was interesting though, I couldnt get the R input to work iether but in my old controller I did find a unused R input that I deleted and now my R input for jump works. Im thinking there must be a spacebar input that is messing up my jump/spacebar input?

I even created a new 3rd person project and my jump sparsely works with space bar!
Exact same issue im having with my main project

I also dont think that its a problem with my computer as I can S p a c e when I need to?

I have no Idea what to do. Is anyone else have this issue?

Hey Hughie,

Do you use any programs such as AutoHotKey to remap any keys?

Another thing you can try, rather than using the “Jump” event, find the “Space” key event and wire the jump nodes directly to it.

If still no luck, could you post a screenshot of both the graph that contains the the Jump code and a screenshot of the Project Settings → Input section?

Hey
I dont use AutoHotKey and I have tryed using the space bar key input directly.

The jump node path is pretty big and I figured it wasnt really as important as I do have a print string right after it letting me know when ever spacebar is actually pressed. When playing I hit the space bar repeatedly and every once and a while I will see the char jump and that the button is pressed.

Im going to try and reinstall the engine from git.

Hi HugieDM,

Do you have any other spacebar functionality that may be consuming the input from your Jump action? I have not been able to reproduce this on my end thus far.

Hey ,
I did a search through the project for any spacebar related inputs and did not find any.
I also reinstalled the engine with no change.
Its also strange as when I create an completely new 3rd person project I have the same issue.
Maybe there is something going on with this PC Im going to try another computer that I have.

Edit: Also noticed while editing a map the space bar no longer switches through the manipulator tools

Found this post to be the exact issue Im have but not much of an answer…

I had an issue a while back where my project lost all input for the “E” key so I had to use an alternate key. I ended up finding it was from building my game on 4.8.2 (on my home desktop) and I had 4.8.3 on my laptop that I use also. I ran it on 4.8.2 that evening and it worked again!

13

Try with an alternate keyboard if you have a second one available. Are you seeing any errors with the spacebar outside of the editor?

14

I did no matter the key board I have the same issue and I dont have any issues with space bar out side of the editor

Hey HughieDM,

I have a few additional questions:

  • You mentioned using a source version of the editor, have you tried this in the Launcher version of 4.12.4? If not, please do so and let me know the results.
  • Are you experiencing this in any of the other templates?
  • Also, try this: create a new, blank project. In the level blueprint, add a space bar pressed event and then run a print string off of that. Does that event fire?
  • Is it possible that you set space bar to be a hotkey for something else in your editor preferences?
16

Hey Sean,

  • I am currently running 4.12.4
  • I did create a fresh 3rd person template to see if it carried over and it does
  • when create that the space-bar fires sporadically like every tenth or twentieth push
  • I did run through my editor hot keys and removed everything and still get the same result. I also noticed that for some reason when hitting the space bar in the view port it used to switch the gizmo but now it happens sporadically just like the above blank project
17
  • What operating system are you currently running?
  • Does this issue occur in any older versions?
  • Could you provide your dxdiag?

The space bar seems to be working as expected on our end, so I’m thinking it could be something related to your setup. Do you have any external plugins installed at all?

18

Im running windows 10 and it was occuring in 4.10 and 4.11 but we haddent started any major work yet. link text

19

We’ve tested this using the 4.12.4 source build, but have been unable to reproduce it on our end. Did you make any changes to any of the config files? Have you enabled any plugins at all in your project?

I do have the victory pluggin and advanced sessions pluggins but nothing experimental turned on. The only things in the config files that I have changed are settings for steam, xbox and PS4.
