Cinemachine InputProvider caches InputActions so overrides do not work

I had to create a custom Cinemachine AxisState.IInputAxisProvider to use the Input System’s generated C# code as opposed to the built-in CinemachineInputProvider because that version caches the actions so any overrides applied later (like for rebinding controls or inverting the axes) are ignored.

Here’s a script for anyone else who runs into this situation:

using System.Linq;
using Cinemachine;
using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.InputSystem.Users;

public class CinemachineLookInputProvider : MonoBehaviour, AxisState.IInputAxisProvider {

    protected InputAction Action => GameInputManager.Actions.Gameplay.Look;

    public float GetAxisValue(int axis) {
        if (base.enabled) {
            switch (axis) {
                case 0:
                    return Action.ReadValue<Vector2>().x;
                case 1:
                    return Action.ReadValue<Vector2>().y;
                case 2:
                    return 0f;
            }
        }
        return 0f;
    }
}
