Question InputAction does not contain "wasPressThisFrame" error

I am "using UnityEngine.InputSystem;"

error CS1061: 'InputAction' does not contain a definition for 'WasPressedThisFrame' and no accessible extension method 'WasPressedThisFrame' accepting a first argument of type 'InputAction' could be found (are you missing a using directive or an assembly reference?)

Code (CSharp):

1. private InputAction[] actions;
2.  
3. public override bool GetTrackActionKeyDown(Track track, int index)
4.         {
5.             var key = actions[index];
6.             return key.WasPressedThisFrame();
7.         }

 

Actions don't have

WasPressedThisFrame

. They can be other things than keys and buttons. They have triggered.

 

Oh you actually added extension methods? May I ask you why did the team choose this over what we have in ButtonControl (property as opposed to methods)? This is super-confusing, even for me.

 

Yes, we are, sorry, for some reason I categorized this as extension method. But the meaning of the question still stands, what is the reasoning to have a method instead of a property meanwhile we already have similar pattern and meaning as property elsewhere.
