How do you know which keyboard key was pressed?

How to know which button was pressed in the new inputSystem? I've been scratching my head now, just to make my typing game works with the new inputsystem.

 

This works

Code (CSharp):

1.        
2. InputSystem.onEvent
3.         .ForDevice<Keyboard>()
4.         .Where(e =>
5.         {
6.             if(e.type != StateEvent.Type && e.type != DeltaStateEvent.Type)
7.             return false;
8.             else
9.             return e.HasButtonPress();
10.         })
11.         .Call(ctrl =>
12.         {  
13.             foreach (var button in ctrl.GetAllButtonPresses())
14.             Debug.Log($"{button} was pressed");
15.         });

But who thought it was much better to do this compared to the legacy? I'm baffled by how hard just to do small things now

 

Thats the method I used before, but that requires separate bindings for other keys by the end-users and that's not ideal bcos I'm making a typing game framework, so it must fit all cases.

Further to that onTextInput keeps spewing "InvalidOperationException: Already have an event buffer set! Was OnUpdate() called recursively?" when I bind some other keys (enter, space, etc...) even tho I did not do anything recursively, this was a bug from prior v1.1 preview which should be fixed in v.1.1.1 which also the version I'm using for my typing game framework.

So the use case here is freedom for both dev who provides the easy-to-use-feature and end-users who will use the framework without having to tinker around, generating file this/that, setting actions here/there.. like oh my.. (big G here)...

Think about this, there are people who depends on full 3rd party framework in Unity engine as a whole without having to know every technical aspects of Unity itself, which also what I'm trying to provide to those who will use my typing game framework, and it's been one hellish of an experience let me tell you.

Either way, props for the Unity InputSystem team who made it happen. I will still use it (because no other better choice!)

 

For reacting to any key press,

onAnyButtonPress

is probably the easiest way.

Code (CSharp):

1. InputSystem.onAnyButtonPress.Call(
2.     button =>
3.     {
4.         if (button is KeyControl key)
5.             Debug.Log($"Key {key.name} pressed! (text: {key.displayName})");
6.     });

(treating

displayName

as typed text generally isn't correct but for a typing game not an altogether unreasonable assumption to make)

Another way (not terribly efficient):

Code (CSharp):

1. var action = new InputAction(binding: "<Keyboard>/*");
2. action.Enable();
3.  
4. action.performed +=
5.     ctx => {
6.         if (ctx.control is KeyControl key && !key.synthetic) // Synthetic is stuff like anyKey.
7.             Debug.Log($"Key {key.name} pressed! (text: {key.displayName})");
8.     };

 

Note to anybody stumbles upon this post.

The solution @Rene-Damm posted for onAnyButtonPress would throw exception bcos of this bug

it was fixed in v1.3


Also, is it possible to get the deviceId with onAnyButtonPress?

 

Code (CSharp):

1. InputSystem.onAnyButtonPress.Call(
2.     ctrl =>
3.     {
4.         Debug.Log($"Button {ctrl} on device {ctrl.device} with ID {ctrl.device.deviceId} was pressed");
5.     });

 

This just recently added? Pretty sure, I can't do this in v1.1

Edit: I did it wrong, i thought I could just ctr.deviceId... so yeah, this works
