Inputsystem.Controls: Key-Input only fires ONCE unless I click into the scene

Unity Engine

I just switched to the new Input System 1.0.0 instead of the old “Input Manager” and now seem to have a weird behavior.

I catch keypress quite simple by the following code:

protected void Update() {
if (Keyboard.current.leftArrowKey.wasPressedThisFrame)
            {
               Debug.Log( "key down");
            }
if (Keyboard.current.leftArrowKey.wasReleasedThisFrame)
            {
                Debug.Log("key up");
            }
}

This script is attached to a not too complex GameObject.

Now when I press the left key (and keep it pressed) the Debug output is fired only once:

[15:01:48] key down
[15:04:48] key up

When I now in preview mode click anywhere into the scene with my mouse suddenly the event is continuously fired instead each Update:

[15:41:21] key down
[15:41:21] key down
[15:41:21] key down
[15:41:22] key down
...
[15:41:38] key up
[15:41:38] key up
[15:41:38] key up
...

In summary: Before clicking anywhere I have exactly ONE output for up and down, after clicking I have a down output for every frame and according ups when releasing the key.

So my question is:
How do I get a consistent behavior? Of course I can simply “remember” that keypress in a property and use that for every following update. But is that the way it should be done? And even if I do so: Why does clicking into the scene change the behavior?

Ok. I received the wanted result by using “isPressed” instead of “WasPressedInThisFrame”. Which makes a lot of sense thinking about it :slight_smile:

Still: Why does this behavior change when clicking into the scene?
