What does "Submit" map to? And can it be changed?

Just wondering if it's possible to customize the default submit button like in the old input system:
https://docs.unity3d.com/2019.1/Documentation/ScriptReference/UI.Button.OnSubmit.html

on windows it's "Enter" key, what about other devices though? gamepad, tv remote?

How can I find where Submit is being set in the new input system?

 

The InputSystemUIModule links to the actions from which it sources input.



By default, that's the DefaultInputActions.inputactions asset that comes with the package.

You can link to your own customized version of the asset and customize the bindings of the Submit action.

 

Sorry I was referring to the "Submit [Any]" binding.
How is that determined?

I know just from experience it's "Enter" on keyboards, "ButtonSouth" on gamepad etc.
But how does the Input system know that? Where does "Submit [Any]" determine that it's the Enter key on desktop and some other key on controller?

What for example, would "Submit [Any]" map to on a Racing Wheel, or some other device?

Same could be said for "Cancel [Any]", why does cancel map to the "B" button on controller and "Esc" on keyboard? And is it possible to change that binding?

Is this something the OS tells you? or is the mapping kinda hidden away in the native low level side?

 

Bumpin for the sweet sweet knowledge



I'd like to know what all these "Any" bindings map to on different devices.
What exactly is "Menu [Any]" on keyboard? or "SecondaryAction [Any]" on a gampad/tv remote?

is there just an "Any [Any]" binding?

so many questions, so little time.

 

After scouring the code, it looks like keyboard has the following usage tags:

{Submit} -> Enter
{Cancel} -> Escape
{Back} -> Escape

I could be looking at the wrong thing, not sure, but to find them I:
1. Find the state layout in question (e.g. https://github.com/Unity-Technologi...y.inputsystem/InputSystem/Devices/Keyboard.cs )
2. Search for "usage" and "usages" to find the InputControlAttributes that are assigned the usage in question. You can also maybe search for the usage in quotes, if needed. (e.g. Searching for "Submit" or "Cancel" with quotes around them.)

If anyone knows an easier way to find these than scouring the code, that would be helpful.

 

Can we get another answer on this? Can you remap the Enter key as UI / Submit to something else? I would like Space key to do UI / Submit and dont know how to do that.

 

In this case you could just remove the Submit [Any] binding and replace it with the Space [Keyboard] binding.
